A performance bond is a three-party agreement, backed by a surety, that guarantees a contractor will finish a construction project on the terms set out in the contract. If the contractor defaults, the surety pays the project owner or hires a replacement to finish the job. Terms, pricing, and required amounts vary by surety, contract, and country, so confirm the specifics with your own surety agent, bank, or attorney.
Federal law requires a performance bond on most federal construction contracts over $150,000, and many public and private owners require one too. If you are a first-time contractor or a small-business owner meeting this term while bidding on a job, here is what it actually is, who is involved, and what it does and does not protect.
How a Performance Bond Works: The Three Parties
Every performance bond names three parties:
- The principal is the contractor, the party who owes the work under the construction contract.
- The obligee is the project owner, the party the bond protects.
- The surety is the company, usually an insurer licensed by the state's insurance regulator to write surety bonds, that backs the bond and pays if the principal fails.
The bond does not replace the construction contract. It sits alongside it. If the contractor performs, the bond is never triggered and nobody sees a payout. If the contractor defaults, meaning it stops work, becomes insolvent, or breaches the contract badly enough that the owner declares a default, the owner makes a formal claim against the bond. The surety investigates the claim and, if it is valid, typically either finances the original contractor to finish the job, hires and pays a new contractor to complete the work, or pays the owner cash up to the bond's penal sum, the maximum amount stated on the bond, usually set at 100% of the contract price on federal work.
Many performance bonds, especially on larger private commercial jobs, are written on the industry-standard AIA Document A312, which spells out the notice and default steps an owner has to follow before making a claim. Others follow the surety's own form or a form a public agency requires.
Performance Bond vs. Payment Bond vs. Bid Bond
| Bond type | What it protects | Who it benefits |
|---|---|---|
| Bid bond | Guarantees a bidder will sign the contract and provide the required bonds if awarded the job | Project owner |
| Performance bond | Guarantees the contractor will complete the work under the contract | Project owner |
| Payment bond | Guarantees subcontractors, laborers, and suppliers get paid | Subcontractors, laborers, suppliers |
On most public jobs, and increasingly on large private ones, performance bonds and payment bonds are issued together and are sometimes called a "performance and payment bond" package, priced as one combined premium. The payment bond matters on federal work in particular because federal property generally cannot be placed under a mechanic's lien, so the payment bond acts as the substitute remedy for a subcontractor or supplier that does not get paid.
Why Project Owners Require a Performance Bond
From an owner's side, a performance bond does two jobs before a single brick is laid. First, it filters bidders: a surety backs a contractor only after underwriting its financials, experience, and track record, so the bonding process itself screens out contractors who are not ready for a project of that size. Second, it moves the financial risk of a default off the owner's books and onto the surety.
That combination is why public agencies favor performance bonds so strongly, and why many private owners on large commercial jobs now ask for one even though nothing legally forces them to.
Who Needs a Performance Bond in Construction: Federal, State, and Private Projects
In the United States, the federal requirement traces back to the Miller Act. The current bonding threshold under the Federal Acquisition Regulation is $150,000: FAR 28.102-1 (read 2026-09-18) states that a performance bond and a payment bond are required for a construction contract exceeding that amount, with limited exceptions such as work performed in a foreign country. Below that figure, contracting officers use alternative payment protections instead of a full bond; many older summaries online still cite the Miller Act's original statutory figure of $100,000, which the regulation has since updated for federal procurement.
Every state has adopted its own version of this rule for state and local public projects, generally called a "Little Miller Act." Thresholds and required protections differ by state, so the number that applies to a state highway contract is not automatically $150,000; it is whatever that state's own statute sets.
Private owners are not bound by any of this. A private developer can require a performance bond on a job of any size, or on none at all. Whether one is required on a private contract is a negotiated term written into the contract documents, not a legal minimum.
What a Performance Bond Costs and Who Qualifies
A surety underwrites a performance bond the way a lender underwrites a loan. It looks at the contractor's financial statements, work history, bank references, current backlog, and the specific project's complexity before deciding whether to issue the bond and on what terms. Because underwriting is individualized, price and required collateral differ from contractor to contractor and from surety to surety, and no single percentage describes every bond. Anyone quoted a number for their own project is looking at that surety's quote for that job, not a market-wide rate, and the only way to get a real number is to ask a surety agent or bank directly.
Small and newer contractors sometimes cannot get bonded through the ordinary commercial surety market because they lack the financial history a surety wants to see. For that situation, the U.S. Small Business Administration runs a Surety Bond Guarantee program that guarantees bid, performance, payment, and ancillary bonds that participating sureties issue to small businesses, on contracts and subcontracts up to $9 million, according to the SBA's surety bonds page (read 2026-09-18). The SBA states that its own guarantee fee for performance and payment bonds is 0.6% of the contract price, refunded if the bond is cancelled or never issued. That figure describes the SBA's program specifically; it is not what every surety charges outside that program.
Getting Bonded as a Small or First-Time Contractor
Bonding capacity is really a question about the health of the business behind the bid, which is why the conversation with a surety agent tends to sound like the conversation with a lender. A contracting business that has been bootstrapping growth from its own revenue rather than outside investors often has to show a surety the same working capital and equity a bank would want to see before extending a line of credit.
Posting collateral for a bond, or simply carrying the retained profit and cash a surety wants to see on the balance sheet, ties up money a business might otherwise use elsewhere. For a young contracting business watching its runway, a large bond request on a single project can be the deciding factor in whether to bid on a job at all.
If a bonded project's payment schedule slips, or a slow month leaves the business short on the cash the bonding relationship expects it to hold, some contractors look at revenue-based financing to bridge a slow month rather than draw down the reserves a surety is counting on. None of these financing choices change what the bond itself requires; they change how a business manages the cash the bonding process assumes it has on hand.
What a Performance Bond Does Not Do
A performance bond is not insurance the contractor can claim against its own losses. It exists solely to protect the project owner. It also does not resolve every dispute automatically: a surety generally investigates a claim before paying and may raise the same defenses the contractor could raise against the owner, which is a different posture from a bank demand guarantee that pays first and sorts out the underlying dispute afterward. And a bond only protects up to its penal sum, so a bond written below the real cost of finishing an abandoned project still leaves the owner short.
None of this replaces reading the specific bond form, the underlying construction contract, and the applicable state's Little Miller Act, where one applies. The surety agent placing the bond, and an attorney who reviews construction contracts, are the people who can say what a particular bond covers and what it leaves out.
FAQ
What is a performance bond in construction, in one sentence? It is a surety-backed promise to the project owner that a contractor's obligations under the construction contract will be met, or that the surety will step in to cover completion if they are not.
Who pays for a performance bond? The contractor pays the premium to the surety, though the cost is typically built into the contractor's bid price and passed through to the project owner as part of the total contract price.
Is a performance bond the same as insurance? No. Insurance spreads risk across policyholders and expects claims. A surety bond works more like a line of credit: the surety expects to be reimbursed by the contractor if it has to pay a claim, and it underwrites the contractor with that expectation in mind.
Do all construction contracts require a performance bond? No. Federal contracts over $150,000 generally require one under the Miller Act framework as implemented in the FAR, and many states require one on public work above their own threshold. Private contracts require one only when the contract itself says so.
Can a small or new contractor get bonded? Often yes, either through a surety that specializes in smaller accounts or through the SBA's Surety Bond Guarantee program, which backs bonds on contracts and subcontracts up to $9 million for small businesses that qualify.
The Short Version
A performance bond protects a project owner if a contractor fails to finish the job, by putting a surety on the hook to complete the work or pay for it. It is required by law on larger federal and state public projects and is increasingly requested on private ones. What a specific bond costs, how much collateral it requires, and whether a specific contractor qualifies are underwriting questions that depend on that contractor, that project, and that surety, so the numbers on any real quote come from a surety agent, a bank, or an attorney, not from a general guide like this one.
