Every year, construction projects are abandoned mid-build. Contractors go bankrupt, miss deadlines, deliver substandard work, or simply walk off a job. When that happens on a project that required a performance bond, the project owner has immediate financial recourse. When it happens on a project that didn’t, the owner absorbs the loss, scrambles to find a replacement contractor at whatever price the market demands, and fights through litigation that may take years to resolve. That difference — between protected and unprotected — is exactly what a performance bond is designed to create.
What Is a Performance Bond?
A performance bond is a surety bond that guarantees a contractor will complete a construction project according to the terms of the contract. If the contractor defaults — fails to finish the work, abandons the project, or delivers work that materially violates the contract — the surety company steps in to protect the project owner from financial loss.
Also called a contract bond, a performance bond creates a legally binding three-party agreement at the outset of a project:
| Party | Who They Are | Their Obligation |
|---|---|---|
| Principal | The contractor who wins the job | Complete the project per the contract terms, on time and to specification |
| Obligee | The project owner or government agency awarding the contract | Required to accept the bond as a condition of awarding the contract |
| Surety | The bond company | Guarantees the principal’s performance; pays valid claims; seeks full reimbursement from the principal |
The bond amount typically equals 100% of the contract value. The surety’s obligation to the obligee is therefore the full contract amount — not a partial guarantee, not a capped payout, but the full exposure of the project’s cost.
When Are Performance Bonds Required?
The Miller Act (40 U.S.C. Chapter 31, Subchapter III) requires performance and payment bonds on all federal construction contracts exceeding $150,000. States have enacted their own equivalents — called Little Miller Acts — that extend the same requirements to state-funded construction. Most state and municipal thresholds mirror the federal standard, though some jurisdictions set lower bars.
Baltimore County, Maryland, for example, requires a performance bond on all projects over $25,000 at 100% of the contract price — a significantly lower threshold than the federal standard. The bond requirement in any jurisdiction is set by the obligee, not by law alone.
Private project owners are not legally required to demand bonds, but many do — particularly when developers, lenders, or investors require assurance that a project will be completed before they commit financing. A lender who has underwritten a construction loan wants confidence that the borrower’s contractor will finish the building. A performance bond provides that confidence through a third party with auditable financial strength.
Performance bonds are also required in non-construction contexts. In commodity trading, a seller may be required to post a performance bond guaranteeing delivery of the commodity to the buyer. If the commodity is not delivered for any reason, the bond provides compensation for the buyer’s lost costs. This extends the product’s utility well beyond construction — into manufacturing supply contracts, government service contracts, and other large contractual obligations where one party needs assurance of the other’s performance.
What Happens When a Contractor Defaults?
Default can take several forms: the contractor stops working entirely, fails to meet quality specifications, misses deadlines by a material margin, or becomes insolvent. When any of these occur, the obligee has the right to file a claim against the performance bond.
The surety does not simply write a check. The surety investigates the claim — reviewing the contract, the work completed, the circumstances of the default, and the validity of the obligee’s position. If the claim is valid, the surety has three options, and it will choose the one that minimizes its own financial exposure:
Complete the project with the original contractor by providing whatever financial, management, or technical support the contractor needs to finish the work.
Re-tender the remaining work to a new contractor and pay the cost of completion in excess of the original contract price. If the defaulted contractor was the low bidder and the replacement costs more, the surety covers the difference up to the bond amount.
Pay the obligee compensation up to the full amount of the bond, allowing the owner to manage the completion however they choose.
The surety’s involvement does not end when the obligee is made whole. Under the personal indemnity agreement signed when the bond was issued, the principal — the defaulted contractor — must repay the surety in full for every dollar paid out, plus legal fees and investigative costs.
On-Demand vs. Conditional Performance Bonds
Most performance bonds used in US construction are conditional bonds. A conditional bond requires the obligee to demonstrate that the contractor has actually defaulted — that a genuine failure to perform has occurred — before the surety is obligated to respond. This gives the surety the ability to investigate, contest invalid claims, and protect the principal from being driven out of a project by an unreasonable or bad-faith obligee.
In international trade and some US commercial transactions, on-demand performance bonds also exist, particularly when they are issued by banks rather than surety companies. A bank-issued performance bond functions similarly to a promissory note payable on demand — the bank pays on the obligee’s claim without requiring proof of default. The obligee simply makes a demand, and the bank pays up to the bond amount. On-demand bonds provide faster, more certain payment to obligees but expose principals to greater risk of unjustified claims.
For contractors evaluating bond requirements in international contracts or large commercial deals, understanding which type of bond is being demanded materially changes the risk profile of signing.
The Surety Bond Facility
Most contractors who regularly bid on bonded work don’t obtain performance bonds one at a time — they establish a surety bond facility. A bond facility is a standing credit relationship between a contractor and a surety that pre-establishes the contractor’s bonding capacity for the year. The facility sets a single-job limit (the maximum bond the surety will write for any one project) and an aggregate limit (the maximum total bonded work the contractor can carry simultaneously).
With a facility in place, a contractor can bid on bonded projects and issue bonds quickly, without undergoing full financial review each time. The facility is established through an initial underwriting process, then renewed annually based on updated financials and project history.
Without a facility, a contractor must apply for each bond individually and provide full documentation for every project. This is feasible for occasional bonded work but impractical for contractors who regularly compete for public projects.
Three Underwriting Tiers
Not all performance bonds are underwritten the same way. The level of scrutiny scales with the size of the project and the financial complexity of the contractor’s situation:
| Program Level | Contract Size | Aggregate Program | Underwriting Depth |
|---|---|---|---|
| Small / Hard-to-Place | Up to $400,000 | Varies | Minimal — credit check and basic application |
| Standard | Up to $3 million | Up to $6 million | Standard — financial statements, credit, project history |
| Full Account | $3 million+ | $6 million+ | Full — audited financials, work-in-progress reports, detailed capacity review |
At the standard and full account level, the three Cs of surety underwriting govern the process — character (integrity, references, track record), capacity (experience, past project size, management depth), and capital (net worth, working capital, debt structure). For full account underwriting, the surety’s evaluation closely resembles a bank’s credit analysis before extending a commercial line of credit.
Performance Bonds vs. Related Bond Types
Performance bonds are frequently confused with or conflated with other contract bond types. Each is a separate product covering a different phase or risk:
Bid Bonds are submitted with a contractor’s proposal during the bidding process. They guarantee that if the contractor wins the bid, they will enter the contract and provide the required performance and payment bonds. A bid bond protects the owner from winning bids that the contractor later refuses to honor. If the contractor declines to execute the awarded contract, the surety pays the difference between the winning bid and the next lowest bid.
Payment Bonds guarantee that the contractor will pay subcontractors, laborers, and material suppliers. On public projects, subcontractors and suppliers cannot place a mechanics lien against government property — the payment bond is their only financial recourse if the general contractor fails to pay them.
Warranty Bonds (also called maintenance bonds, or issued as AIA A313-2020) are a distinct instrument from performance bonds. Where a performance bond guarantees that the work will be completed, a warranty bond guarantees that the completed work will be free from defects in materials and workmanship for a defined post-completion period — typically one to two years. Some projects require both a performance bond during construction and a separate warranty bond for the post-completion period.
Rural Utilities Service (RUS) Bonds are a specific federal variant required for contractors working on RUS infrastructure projects exceeding $250,000. These bonds are issued to the USDA Rural Utilities Service and carry specific form and filing requirements beyond standard commercial performance bonds.
Performance Bonds vs. Alternative Security Instruments
A performance bond is not the only way to satisfy a security requirement. Some obligees — particularly at the municipal and county level — accept alternatives including letters of credit, cashier’s checks, or cash deposits. Understanding the practical differences helps contractors make an informed choice.
| Security Type | Ties Up Credit Facility | Ties Up Cash | Surety Investigates Claims | Premium / Cost |
|---|---|---|---|---|
| Performance Bond | No | No | Yes — investigation before payment | 1-5% annually |
| Letter of Credit | Yes — draws on bank line | No | No — bank pays on demand | Bank fees, plus reduces borrowing capacity |
| Cash Deposit | No | Yes — full bond amount deposited | No | No premium, but full capital at risk |
A $500,000 letter of credit reduces available borrowing by $500,000 for the life of the project. A $500,000 cash deposit requires the contractor to park $500,000 in funds that cannot be used elsewhere. A $500,000 performance bond typically costs $7,500 to $25,000 in premium and leaves both the credit line and cash available for operations.
Why Surety-Backed Projects Perform Better
Performance bonds improve construction outcomes measurably, not just theoretically. Research commissioned by the Surety & Fidelity Association of America (SFAA) and conducted by an independent firm found that bonded construction projects default at lower rates, cost less to complete when they do encounter problems, and finish at higher rates than comparable unbonded projects. The mechanism is predictable: surety underwriting filters out financially underprepared contractors before they start.
The eligibility standard for a surety bond is not just financial — it is operational. A contractor who has never managed a $10 million project cannot simply buy a bond for one. The surety will not underwrite a project that is materially larger or more complex than the contractor’s demonstrated history. This pre-qualification function has no equivalent in insurance — any contractor can buy general liability insurance. Not every contractor can get a performance bond. The fact that a contractor obtained one tells the project owner that an independent, financially regulated third party has already evaluated them and found them creditworthy.
How to Get a Performance Bond
Apply with a surety agency that handles construction bonds regularly. For projects under $400,000, basic application information and a credit check are often sufficient to generate a quote within one business day. For larger projects, be prepared to provide personal and business financial statements, a list of completed projects with references, a completed contractor questionnaire, and the contract documents for the specific project. Pay the premium after review and approval. Submit the executed bond to the obligee — typically the government agency or project owner — before mobilizing on the project.
The 10-day rule applies on many government contracts: after winning a bid, the contractor typically has 10 days (or the timeline stated in the bid specifications) to respond and provide the required bonds. Missing this window can forfeit the award.

Frequently Asked Questions
What is a performance bond? A performance bond is a surety bond that guarantees a contractor will complete a construction project according to the terms of the contract. If the contractor defaults, the surety company steps in — completing the project, hiring a replacement contractor, or compensating the project owner up to the full bond amount.
When is a performance bond required? Performance bonds are legally required on all federal construction contracts over $150,000 under the Miller Act. State and local governments have similar requirements under Little Miller Act statutes, with some jurisdictions setting lower thresholds. Private project owners may also require performance bonds as a condition of their contract award, regardless of legal mandate.
How much does a performance bond cost? Most performance bonds cost between 1% and 5% of the total contract value. Well-qualified contractors with strong credit and financial statements typically pay 2.5% to 3%. Higher rates apply for larger programs, weaker credit, or new contractors without an established track record. The premium is typically included in the contract price and is effectively borne by the project owner.
What are the three things a surety can do when a contractor defaults? When a contractor defaults, the surety can: (1) provide financial, management, or technical support to allow the original contractor to complete the project; (2) re-tender the work to a new contractor and pay any excess cost over the original contract price; or (3) pay the project owner compensation up to the full bond amount. The surety chooses the option that minimizes its own financial exposure while making the obligee whole.
What is the difference between a performance bond and a payment bond? A performance bond guarantees project completion — that the contractor will finish the work per the contract terms. A payment bond guarantees that the contractor will pay subcontractors, suppliers, and laborers. Both are typically required together on public projects. Performance bonds protect the owner; payment bonds protect the project’s trade contractors and material suppliers.
What is the difference between a performance bond and a warranty bond? A performance bond covers the construction period — guaranteeing the contractor completes the work. A warranty bond (also called a maintenance bond, or issued as AIA A313) is a separate instrument covering post-completion defects in materials and workmanship for a defined period after the project is accepted. Some projects require both.
Can a contractor get a performance bond with bad credit? Yes, though at a higher premium. Specialty surety programs exist for contractors with challenged credit, past bankruptcies, or limited financial history. The premium will reflect the elevated risk, but bondability is not limited to only contractors with excellent credit. Factors beyond credit — experience, project history, available working capital — all affect both eligibility and pricing.
When does a performance bond end? A performance bond terminates when the project is completed in accordance with the contract and the obligee accepts the work. At that point, the performance obligation is fulfilled and the bond is discharged. A payment bond terminates separately, once the contractor provides documentation confirming all subcontractors and suppliers have been paid in full and the obligee signs off on that confirmation.
Conclusion
A performance bond is the construction industry’s financial backbone — the instrument that allows project owners to award large contracts to contractors they cannot fully vet on their own, with the confidence that a financially regulated third party has already done the evaluation and stands behind the result. For contractors, a performance bond is simultaneously a credential and a credit product: evidence of financial stability, proof of professional track record, and access to projects that would otherwise be unavailable. Understanding how performance bonds work — from the three underwriting tiers to the options available when claims arise — is foundational knowledge for anyone who builds, owns, develops, finances, or manages construction projects of any meaningful scale.
5 Things About Performance Bonds That Most Contractors and Owners Never Learn
- The surety’s goal when investigating a performance bond claim is not to pay the obligee — it is to find a way to complete the project for less than the bond amount, and the surety often has more legal tools to accomplish this than the project owner does. When a contractor defaults, the instinct of most project owners is to file a bond claim and expect payment. In practice, a sophisticated surety will first exhaust every option that costs less than paying the full bond. The surety can invoke its right to step in as the effective project manager, negotiate directly with subcontractors already on site, and complete the project for a fraction of what terminating and re-bidding would cost. Sureties also have subrogation rights — when they pay a claim, they step into the obligee’s legal shoes and can pursue the defaulted contractor’s assets, pending payments, and performance claims against any third parties responsible for the contractor’s failure. A surety that pays a $2 million claim on a $2 million bond does not simply absorb that loss. It pursues recovery from the principal’s assets, from indemnitors who co-signed the bond, and from any third party whose actions contributed to the default. Project owners who understand this tend to maintain better working relationships with sureties during default proceedings — because the surety is often working harder than the owner to get the project finished.
- A performance bond’s protection for the project owner is only as strong as the surety company’s financial strength, and the US Treasury’s Circular 570 Listing of Approved Sureties exists specifically to prevent project owners from accepting bonds from companies that cannot actually pay claims. A performance bond is only as valuable as the surety’s ability to honor it. An insolvent surety’s bond is worthless — and surety insolvencies do occur. The US Department of the Treasury maintains a list of approved surety companies (the 570 Circular) that are certified as financially sound and licensed to write federal bonds. On federal projects and most state projects, bonds must come from a 570-listed carrier. Private owners and municipal obligees who accept performance bonds from unlisted carriers may discover at the worst possible moment that their financial backstop cannot pay. Requiring that any accepted performance bond come from an A.M. Best A-rated surety listed on the Treasury Circular 570 is not bureaucratic formality — it is basic due diligence that prevents the bond guarantee from being theoretical rather than real.
- The performance bond does not cover every type of project failure — it covers the specific contractual obligation defined in the bond form, and disputes about whether a particular failure is “within scope” of the bond are among the most litigated questions in construction law. Most project owners assume a performance bond covers everything that could go wrong with a contractor. It doesn’t. The bond’s coverage is defined precisely by the underlying construction contract it references and by the terms of the bond form itself. Design errors, differing site conditions, owner-directed changes, force majeure events, and delays caused by the owner’s own actions are typically not covered because they are not the contractor’s performance failure. A contractor who encounters an unforeseen subsurface condition and falls behind schedule has not defaulted — the contract likely has provisions for schedule adjustment. An obligee who attempts to call the bond in that circumstance will face a surety that contests the claim vigorously, because the failure was not the contractor’s failure to perform. The AIA A312 Performance Bond form is one of the most widely used standard forms precisely because its claim procedures are specific: the obligee must declare the contractor in default, give the contractor the opportunity to cure, and follow defined notice requirements before the surety’s obligation is triggered. Failing to follow the form’s procedures can invalidate the claim entirely.
- Performance bonds played a direct role in making large-scale American infrastructure possible in the 20th century, and the legislative framework that mandates them — the Miller Act — was itself the corrective response to catastrophic project failures that exposed the federal government to losses that could not be recovered. The Heard Act of 1894 first required bonds on federally funded construction, but the regime it created had significant gaps. Contractors regularly defaulted, subcontractors went unpaid, and the government had limited recourse. When the Miller Act was enacted in 1935, it established the modern framework — mandatory performance and payment bonds on all federal construction over the applicable threshold, with specific claim rights for subcontractors and suppliers who had previously had no protection on government projects. The Miller Act fundamentally changed the risk profile of public construction: it transferred the underwriting function from the federal government (which had no expertise in evaluating contractor financial capacity) to private surety companies whose entire business model depended on accurately assessing that capacity. This outsourcing of credit evaluation to specialized private companies is a design principle that has been replicated in construction procurement systems around the world and that continues to define how governments manage contractor risk today.
- When a performance bond claim is paid and the surety steps in to complete a project, the surety’s completion costs often exceed the original contract value — and the original bond amount — yet the surety may still be contractually obligated to ensure the project reaches substantial completion, even at a financial loss on the specific claim. Many obligees and contractors misunderstand the performance bond as a simple payment guarantee capped at the bond amount. In practice, when the surety takes the “completion option” — exercising its right to manage and fund the completion directly — it can spend more than the bond amount if that is what responsible project management requires. The bond amount defines the maximum the surety will pay to the obligee in cash; it does not cap the surety’s total exposure when it chooses to complete the project using its own resources. A defaulted $5 million project may require $6.5 million to complete when accounting for re-mobilization costs, premium pricing from contractors willing to take on a distressed project, acceleration costs to meet deadlines, and the cost of defending prior work that subcontractors dispute. The surety then pursues the $1.5 million excess through the indemnity agreement, through subrogation against the defaulted contractor’s assets, and through any claims the surety can bring as the contractor’s assignee. This is why surety underwriting is as rigorous as it is — the surety’s exposure on a bond claim is not bounded by the bond amount if it chooses to complete rather than pay.
