You already know performance bonds cost “somewhere between 1% and 3%.” Every bonding website says the same thing. What they don’t tell you is why a roofing contractor pays more than a general contractor on the same dollar amount, why a contractor with no previous bonded projects can’t always get the bond they need regardless of their credit score, or why your quote might be $500 more than the math suggests. This guide fills those gaps — with worked examples, the rules most sites skip, and a clear picture of every cost factor that moves your number up or down.
The Short Answer
Performance bonds for US construction projects typically cost between 0.5% and 3% of the total contract amount for well-qualified contractors. On smaller projects or for contractors using credit-only programs, rates of 2.5%–3.5% are common. On large contracts with full financial underwriting, rates can fall below 1%. The premium is a one-time charge for the duration of the project — not an annual fee — and it is fully earned by the surety from the moment the bond is issued.
One thing to know immediately: the bond premium is calculated on the full contract amount, not on the bond face value. If a project owner requires a 50% performance bond on a $500,000 contract, your premium is calculated on $500,000 — not on $250,000. The percentage required does not reduce the premium base.
What a Performance Bond Actually Guarantees
A performance bond is a three-party agreement between the contractor (the principal), the project owner (the obligee), and the surety company. The surety guarantees that if the contractor fails to complete the project according to the contract terms, the obligee will be made whole.
What most contractors don’t fully appreciate: the surety does not simply write a check if you default. They may put the project out to bid with select replacement contractors, hire a contractor directly to complete the remaining work, or in some cases complete the work using their own resources. Whatever the surety spends to resolve the default, they recover from the contractor — the full amount, plus interest and fees. Performance bonds are not insurance. They are a form of credit.
This distinction matters because it explains why underwriting is so thorough. The surety is not setting a premium to cover expected losses. They are pre-qualifying you and certifying to the project owner that you are financially capable of completing the work.
How Performance Bond Rates Are Determined
Performance bond rates in the United States are regulated. Every surety company that writes contract bonds must file its rates with the state insurance commissioner in each state where it operates. The Surety and Fidelity Association of America collects loss cost data from member surety companies — which account for approximately 98% of all surety premium written in the US — and uses that data to help its members develop rate filings. The rates you are quoted are not arbitrary. They reflect actuarial history on construction performance across different work types.
Within that regulatory framework, several factors push your specific rate up or down.
Credit Score For bonds under $350,000–$500,000, personal credit is the most heavily weighted single factor — industry data suggests creditworthiness drives up to 80% of bond pricing decisions on smaller accounts. A contractor with a credit score above 700 qualifies for meaningfully lower rates than one in the 600s. Poor credit does not automatically disqualify you, but it moves your rate into the 3%–5% range and may require additional documentation or support tools.
A practical note contractors ask about: applying for a performance bond quote does not affect your credit score the same way a mortgage or loan application does. Surety bond credit checks are generally soft inquiries, or at minimum have significantly less impact than traditional credit applications. Shopping multiple surety companies for quotes is not the credit-damaging exercise contractors sometimes fear.
Financial Statements and Their Quality For bonds above roughly $500,000, financial statements become as important as credit. More significantly, the quality and scope of those statements directly affects your rate tier. Surety companies evaluate financial documentation differently:
- Internally prepared statements carry the least credibility
- CPA Compiled statements are better, but the CPA provides no assurance
- CPA Reviewed statements provide limited assurance and qualify for better rate tiers
- CPA Audited statements provide the highest level of assurance and the best rates
The difference between a CPA Compilation and a CPA Review can translate to a rate change of 0.5%–1.5% on large bonds. On a $2 million project, that is $10,000–$30,000 in premium. A quality construction-focused CPA review typically costs $5,000–$15,000. The math frequently favors upgrading.
Work Class and Type Performance bond rates are not uniform across all construction types. Surety companies classify work into categories — general construction, roofing and specialty trades, asphalt paving, subdivision and completion work — each with different base rates reflecting historical claim frequencies. A roofing contractor and a general building contractor submitting identical financials for the same dollar amount will be quoted different base rates because roofing carries a higher historical loss frequency.
Experience and Track Record Surety companies look at your history on comparable work: how many projects you have completed, at what contract values, and whether any prior bonds resulted in claims. For new contractors — specifically those with less than one year in business — most sureties limit bond availability to smaller projects until a track record is established. This limitation is separate from credit requirements and applies regardless of how strong your personal finances look on paper.
The 1.5x Largest Completed Job Rule This is one of the most important practical limitations in performance bonding, and almost no consumer-facing surety content explains it. As a general rule of thumb, surety companies require that the project being bonded fall within approximately 1.5 times the contractor’s largest previously completed job. A contractor whose largest completed project was $600,000 will typically be limited to bonding projects up to around $900,000, regardless of credit or financial strength.
This rule exists because financial capacity and field experience are different things. A contractor can be financially strong and still face serious difficulty managing a project three times larger than anything they have previously completed. Sureties price for execution risk, not just credit risk. The implication for growing contractors: the path to larger bond limits runs through successfully completing progressively larger projects, not just through improving your balance sheet.
The Bond Amount Itself The absolute dollar amount of the bond affects your rate through the sliding scale structure: rates decline as contract value increases. This is why a contractor on a $10 million project often pays a lower percentage than the same contractor on a $200,000 project. Larger projects warrant deeper underwriting and attract larger, more financially established contractors — both of which reduce the surety’s risk profile relative to the premium.
What Performance Bond Rates Actually Look Like
Rather than abstract ranges, here is how rates are structured in practice.
Most contract bond companies use a tiered sliding scale where the rate per $1,000 of contract value decreases as the contract grows. A standard Class B general construction rate might look like this:
| Contract Range | Rate per $1,000 |
|---|---|
| First $100,000 | $25.00 (2.5%) |
| Next $400,000 ($100K–$500K) | $15.00 (1.5%) |
| Next $500,000 ($500K–$1M) | $10.00 (1.0%) |
| Next $1,500,000 ($1M–$2.5M) | $7.50 (0.75%) |
| Over $2,500,000 | $5.00 (0.50%) |
Worked Example — $1,000,000 Contract:
- First $100,000 ÷ 1,000 = 100 × $25.00 = $2,500
- Next $400,000 ÷ 1,000 = 400 × $15.00 = $6,000
- Next $500,000 ÷ 1,000 = 500 × $10.00 = $5,000
- Total Premium: $13,500 (blended rate: 1.35%)
Worked Example — $2,500,000 Contract:
- First $100,000: $2,500
- Next $400,000: $6,000
- Next $500,000: $5,000
- Next $1,500,000 ÷ 1,000 = 1,500 × $7.50 = $11,250
- Total Premium: $24,750 (blended rate: 0.99%)
Worked Example — $500,000 Contract:
- First $100,000: $2,500
- Next $400,000 ÷ 1,000 = 400 × $15.00 = $6,000
- Total Premium: $8,500 (blended rate: 1.70%)
These examples use standard rates. Preferred and Merit tier contractors with stronger financials qualify for lower rates within this same structure.
Performance Bond Cost by Contractor Profile
The table below summarizes realistic premium ranges across common project sizes:
| Contract Amount | Strong Financials / Merit (0.5%–1.5%) | Standard Financials (1.5%–2.5%) | Credit-Only (2.5%–3.5%) |
|---|---|---|---|
| $100,000 | $500 – $1,500 | $1,500 – $2,500 | $2,500 – $3,500 |
| $250,000 | $1,250 – $3,750 | $3,750 – $6,250 | $6,250 – $8,750 |
| $500,000 | $2,500 – $7,500 | $7,500 – $12,500 | $12,500 – $17,500 |
| $1,000,000 | $5,000 – $15,000 | $15,000 – $25,000 | $25,000 – $35,000 |
| $5,000,000 | $25,000 – $75,000 | $75,000 – $125,000 | Not typically available |
| $10,000,000 | $50,000 – $150,000 | $150,000 – $250,000 | Not typically available |
Credit-only programs — which allow bonds up to roughly $1.5 million without financial statements, based solely on personal credit — are typically not available for very large bond amounts because surety companies require demonstrated execution capacity at that scale, not just personal financial reliability.
Credit-Only Programs vs. Full Underwriting
For contractors who don’t have CPA-prepared financial statements, need a bond quickly, or are bonding infrequently, credit-based programs offer a streamlined path. These programs allow performance bonds to be issued — often within 24–48 hours — based solely on the personal credit scores of the company’s owners.
The tradeoff is premium. Credit-only programs typically price at flat rates of 2.5%–3.5%, regardless of project size. The sliding scale does not apply. On a $500,000 project, the difference between a credit-only flat rate of 3% ($15,000) and the standard sliding scale for a qualified account ($8,500) is $6,500 on a single bond.
For contractors who bond projects infrequently, the speed and simplicity of credit-only bonding often justifies that cost. For contractors who bond multiple projects per year, the cumulative premium difference makes investing in full financial underwriting — and in upgrading CPA statement scope — a compelling financial decision.
Do Performance Bonds and Payment Bonds Cost More Together?
There is a common misconception worth addressing directly, because some bonding sources repeat it incorrectly: combining a performance bond and a payment bond does not increase the total premium.
The industry-standard position, confirmed across surety underwriting practice, is that a performance bond issued alone costs the same as a performance bond issued together with a payment bond. The obligee receives two separate guarantees for the same single premium. If a project owner requires only a performance bond without a payment bond, the premium remains unchanged — there is no discount for omitting the payment bond.
One application covers both bonds. The process is no more complicated than a single bond application.
The exception is a maintenance or warranty bond issued independently after the performance bond period closes. Standalone maintenance bonds are typically priced at higher rates than when a maintenance obligation is bundled into the original performance bond at issuance.
The Bid Bond to Performance Bond Transition
If you submitted a bid bond to win a project and then approach a different surety company for the final performance bond, underwriters will notice — and they will ask why.
The surety who issued your bid bond prequalified your ability to provide the final bonds if you won. If you are now shopping elsewhere for the performance bond, the new surety’s first question is whether the original surety declined to write the final bonds. That answer, even if it is simply “I wanted to compare pricing,” raises a flag. The original surety’s implicit decision not to follow through with the performance bond is the kind of signal that can make approval harder at the new company.
Unless you have a clear and credible reason for the switch — the original surety does not write bonds in your state, they lack appetite for that bond size, your broker secured substantially better terms — plan to use the same surety for both the bid bond and the final performance bond. Or if you are switching, be prepared to explain why clearly and proactively.
Additional Costs That Affect Total Bond Expense
The percentage ranges above apply to the base performance bond premium. Several other cost factors can significantly change what you actually pay.
Design-Build Surcharge (20%–50% of Base Premium) Design-build contracts carry additional risk because the principal contractor is responsible for design liability, even if the design work is entirely subcontracted. Most surety companies apply a design-build surcharge of 20%–50% of the standard bond premium when the contract carries design-build scope. This surcharge applies even when the design is handled by a licensed engineering subcontractor. If your contract includes the words “Design-Build,” confirm the surcharge with your broker before submitting your bid.
Time Completion Surcharge (Typically ~1% per Month Beyond 12 Months) Standard bond rates cover up to 12 months of project duration. Projects expected to take longer than 12 months incur a time surcharge — roughly 1% of the base premium per additional month. A project requiring 18 months generates a 6% surcharge on top of the base premium. An 18-month, $500,000 project with a base premium of $8,500 would carry an additional $510 time surcharge for a total of $9,010.
Maintenance and Warranty Period Costs Most construction contracts include a warranty period after project completion. Surety companies typically include a standard 12-month maintenance period in the base premium at no additional charge. Extended warranty requirements — 24 months, 36 months, or longer — trigger additional premium calculated using separate maintenance rate schedules. Each additional year of maintenance on a $500,000 contract typically adds $1,000–$1,500 to the total premium.
Minimum Premiums Surety companies maintain minimum premium floors — typically $100–$500 — regardless of the contract amount or the stated percentage rate. On very small contracts, the minimum premium applies even when the calculated percentage would come out lower. A contractor bonding a $30,000 project at a 1% rate would expect a $300 premium, but if the surety’s minimum is $500, that minimum governs. Budget for minimums when estimating bond costs on small-value contracts.
SBA Surety Bond Guarantee Program Fee (0.6% of Contract Amount) The Small Business Administration guarantees qualifying contractors’ performance bonds for projects up to $9 million through a direct federal guarantee to the surety. The program makes bonding accessible to contractors who might not otherwise qualify through standard underwriting. The cost to the contractor: 0.6% of the bonded contract amount, paid directly to the SBA before the bond is issued. On a $500,000 project, the SBA fee adds $3,000 to the total bond cost on top of the regular premium.
Funds Control (0.75%–1.0% of Contract Amount) When a contractor’s financial profile raises concerns, sureties sometimes require a funds control arrangement. A third-party funds control company acts as an escrow manager, controlling the flow of contract proceeds to ensure subcontractors and suppliers are paid before the principal contractor can draw operating profit. Funds control companies charge 0.75%–1.0% of the contract amount for this service. On a $500,000 contract, funds control adds $3,750–$5,000.
What Happens When Contract Costs Change
Performance bond premiums are based on the final contract price, not the original bid. Change orders that increase the contract value create overruns — additional premium owed to the surety. Change orders that decrease the final contract value create underruns — premium the surety owes back to the contractor.
On a sliding scale rate, overruns and underruns are not strictly proportional. An overrun pushes additional contract value into the next (lower-rate) tier, meaning the incremental cost per dollar of overrun is less than the initial cost per dollar. An underrun removes from the highest-rate tier first, meaning the refund per dollar of underrun may be higher than the initial cost per dollar at that level. Surety companies invoice overruns at project completion and issue refunds for underruns at that same time.
Track your bonded contract amount against your running final contract price throughout the project. A large change order near project completion produces a bond invoice you may not be expecting if you have not been monitoring this.
Performance Bond vs. Completion Bond
These terms are sometimes used interchangeably, but they describe different instruments with different purposes.
A performance bond guarantees that a contractor will complete a specific contract according to its terms. It is issued per contract and covers that contract’s obligations.
A completion bond guarantees the completion of an entire project — including all contracts within it. Completion bonds are most commonly required by banks and financial institutions when lending money to developers. They are also used in film and video game production where a completion guarantee is required to secure production financing. A developer securing construction financing for a multi-contract building project might be required to provide a completion bond for the overall project, while individual trade contractors on that same project each provide their own performance bonds per their respective contracts. Both can be required simultaneously for the same project.
Completion bonds are carefully underwritten, typically requiring corporate financials, personal financials, credit reports, industry experience, detailed project information, and sources of project funding. Rates for well-qualified applicants typically run 1%–3% of the total project amount — similar to performance bonds, but with significantly more intensive documentation requirements.
How to Get a Performance Bond
Apply, receive a Quote, Pay the premium, File the bond with the project owner or contracting agency.
For credit-only bonds under $350,000–$500,000, expect same-day to 48-hour turnaround with a simple application and personal credit check. For bonds requiring full financial underwriting, plan 5–15 business days and have your CPA-prepared financial statements, work-in-progress schedule, completed contracts report, and personal financial statement ready at application.
Work with a surety agency that specializes in contract bonds. A general insurance agent who occasionally places bonds lacks the market relationships and underwriting expertise to access the best rates or navigate the approval process on complex accounts. Swiftbonds writes performance bonds in all 50 states and works with well-qualified contractors and those who need specialized programs including credit-challenged accounts and SBA-backed bonding.

Frequently Asked Questions
How much does a $100,000 performance bond cost?
For a qualified contractor with strong credit and financial history, approximately $500–$1,500. For a contractor using a credit-only program, typically $2,500–$3,500. The exact rate depends on the class of work, the contractor’s financial profile, and the surety company used.
Is the bond amount the same as the bond cost?
No. The bond amount is the maximum coverage provided to the project owner — it is the face value of the guarantee. The bond cost is the premium you pay, which is a small percentage of that amount. A $1,000,000 performance bond does not cost $1,000,000. It costs anywhere from $5,000 to $35,000 depending on your qualifications.
Does getting a performance bond quote hurt my credit?
Generally no. Surety bond credit inquiries are typically soft pulls or carry significantly less impact than traditional loan or mortgage applications. Shopping multiple surety companies for quotes is not the credit-damaging exercise some contractors assume it is.
Do performance and payment bonds cost more together than separately?
No. A performance bond costs the same whether issued alone or paired with a payment bond. The obligee receives both coverages for a single premium payment. Some sources incorrectly state that combined bonds cost 1.5–2 times the single bond rate — this is not consistent with how performance and payment bond pricing actually works.
Can a new contractor get a performance bond?
Yes, but with limitations. Contractors with less than one year in business are typically limited to smaller projects. Additionally, most sureties apply a rule of thumb that the bond amount cannot exceed approximately 1.5 times the contractor’s largest previously completed project. A brand-new contractor with no completed projects faces significant bond size restrictions regardless of credit strength.
What is the minimum premium for a performance bond?
Most surety companies maintain minimum premiums of $100–$500 regardless of the contract amount. On very small contracts, the minimum premium may be higher than what the stated percentage rate would calculate to. Always confirm the minimum with your surety when bonding small-value projects.
Can I get a performance bond with bad credit?
Yes in most cases, though at higher rates — typically 3%–5% and sometimes higher. Contractors with open bankruptcies, unsatisfied liens, or open judgments face the greatest difficulty. For contractors who cannot qualify through standard or credit-only programs, the SBA Surety Bond Guarantee Program provides a federal backstop that makes bonding accessible for qualifying small contractors.
What happens if my project costs more than the original contract amount?
Change orders that increase the final contract price create an overrun — additional premium owed to the surety at project completion. The overrun is calculated at the applicable rate tier for the added contract value. The surety company may send progress reports and status requests to the obligee during the project and will issue the overrun invoice when the final contract amount is confirmed.
What is a completion bond and how is it different from a performance bond?
A completion bond guarantees an entire project, typically required by banks financing development. A performance bond guarantees a specific contract within a project. A large development may require both — a completion bond for the developer’s loan guarantee, and separate performance bonds from each trade contractor. They serve different parties (the lender vs. the owner) and cover different scopes.
Conclusion
Performance bond cost is a function of who you are as a contractor, what work you are performing, how well your financial story is documented, and whether your project includes any of the factors that trigger surcharges — design-build scope, extended timelines, long warranty periods. The 0.5%–3% range that gets repeated everywhere is real, but it collapses an enormous amount of variation into a number that tells you almost nothing useful for budgeting. The contractors who consistently get rates at the low end of that range are not luckier than the ones at the high end. They have spent years building the financial documentation, track record, and surety relationships that qualify them for the best rate tiers. That work starts with understanding exactly how the rate you pay is determined — and where there is room to improve it.
5 Things About Performance Bond Cost You Won’t Find on Other Sites
- Surety companies cap your bond size relative to your largest completed project — and no amount of credit can override it. The 1.5x largest completed job rule is one of the most practically limiting factors in performance bonding for growing contractors, and it appears on almost no consumer-facing surety site. A contractor who has never completed a project larger than $400,000 cannot typically get bonded on a $1.5 million project regardless of financial strength. The surety is underwriting execution capacity, not just financial capacity. These are different risks. The path to larger bonds runs through successfully completing progressively larger projects, documented with completed contract reports and work-in-progress schedules that your surety broker can present to underwriters on your behalf.
- The same surety who wrote your bid bond expects to write your performance bond — and if you switch, you owe them an explanation. The bid bond is the surety’s prequalification of your ability to provide final bonds. When a different surety writes the performance bond, the new underwriter’s first assumption is that the original surety declined. That implication follows you into the new application whether you address it or not. Contractors who switch sureties between bid and performance bonds without a clear reason — better terms documented in writing, the original surety lacks state license, the original surety doesn’t write that bond size — should expect additional scrutiny and should proactively address the switch in their application.
- Minimum premiums exist, and on small contracts they can exceed what your quoted percentage would produce. A 1% rate on a $20,000 project would calculate to $200. But most sureties maintain minimum premiums of $300–$500, meaning the actual charge for a very small bond is higher than the stated rate implies. This matters when you are estimating bond costs for multiple small-value subcontracts, where the minimum premium compounds across bonds and produces a total bonding cost that looks nothing like the published rate percentage. Always confirm the minimum with your surety on small-value bonds before you build your bid.
- The quality of your CPA financial statement is itself a pricing variable — not just a qualification threshold.Most bonding guides treat financial statements as either present or absent. The reality is more granular: whether your statement is a Compilation, a Review, or an Audit determines which rate tier you qualify for at class-rating surety companies, independent of the numbers inside the statement. A contractor with $2 million in net worth and a CPA Compilation may be offered only a flat rate at a large national surety. The same contractor with a CPA Review qualifies for the sliding scale rate structure — and on a multi-million-dollar annual bond program, the premium difference across a year’s worth of projects can fund the cost of the upgraded statement several times over.
- Performance and payment bonds cost exactly the same whether issued together or separately — and any source saying combined bonds cost 1.5–2x is giving you incorrect information. This specific misconception appears in at least one currently-ranking surety website. The industry-standard position, consistent with how surety underwriting actually works, is that the premium for a performance bond is identical whether the payment bond is included or not. The obligee receives two separate legal instruments for one premium. The confusion likely stems from how combined bond quotes are sometimes presented — as a total dollar figure that looks larger than a single-bond quote — without clarifying that the single-bond quote would be the same amount.
