A performance bond on a $1 million federal job costs a well-qualified contractor about $10,000 to $15,000 in premium, or roughly 1% to 1.5% of the contract, but the same bond on a shaky balance sheet can cost $30,000 or be flatly declined, which is why bonding, not bidding, is what actually keeps most small contractors out of public work. I have watched capable crews with the low bid lose a job because they could not get bonded, and I have watched better-capitalized competitors with higher prices win purely because the surety would back them. The bond is the gate, and the premium rate is a direct readout of how your surety grades your business.
Here is the part nobody tells you when you are starting out: the bond premium is not really a cost of the project, it is a cost of your company's financial reputation. Two contractors bidding the identical $2 million job can pay wildly different premiums for identical coverage. Let me explain how the thresholds work, what the rates actually run in 2026, and exactly how a small shop builds the bonding capacity to compete.
The Miller Act and When Bonds Are Required
Public work runs on statutory bonding requirements, and the federal rule is the model most states copy. Knowing the thresholds tells you which jobs you can even chase.
Federal Miller Act thresholds
The federal Miller Act requires performance and payment bonds on federal construction contracts exceeding $150,000. For contracts between $35,000 and $150,000, a payment bond or alternative payment protection is required but a performance bond may not be. Below $35,000, bonding is generally not mandated. These are the current thresholds under the Federal Acquisition Regulation as of 2026. The performance bond is almost always written at 100% of the contract value, and the payment bond is also typically 100% of the contract value, so a $1 million federal job requires $2 million of total bonding coverage.
The two bonds do different jobs. The performance bond protects the government owner: if you default, the surety steps in to finish the work or pay to have it finished. The payment bond protects your subs and suppliers: if you fail to pay them, they make a claim against the payment bond rather than lien the public property (you cannot lien federal or most public property, which is exactly why the payment bond exists).
State and local "Little Miller Acts"
Every state has its own version, commonly called a "Little Miller Act," with thresholds that vary widely. Some states require bonds on public contracts as low as $25,000; others match the federal $150,000 or set their own figures. Municipal and county jobs often set their own bonding rules on top of the state statute. Before you chase a public job, confirm the exact bonding threshold and coverage percentage in the solicitation, because it drives your bid cost. If public work is new territory for you, our guide on how to win public-works construction contracts walks through the prequalification steps that sit alongside bonding.
Bond Premium Rates in 2026
The premium is what you pay the surety for the bond, and it is a sliding scale tied to your creditworthiness and the contract size. This is the number you build into your bid.
How the rate scales
Bond premiums generally run 0.5% to 3% of the contract value in 2026, and the rate drops as the contract gets bigger and your qualifications improve. Standard-market rates for well-qualified contractors follow a tiered schedule: roughly 2.5% to 3% on the first $100,000, then stepping down to around 1.5% on the next several hundred thousand, and down toward 1% or less on amounts above $1 million. A strong contractor on a large job blends out to about 1% to 1.5% overall; a newer or credit-challenged contractor working through a specialty or SBA-backed program can pay 2.5% to 3% or more.
The Surety and Fidelity Association of America (SFAA) publishes rate guidance the standard market broadly follows, but the applied rate is underwriting-specific. Two things move it: your financials and the job's risk profile. Weak working capital, thin margins, or a troubled project history push you toward the top of the range or into the higher-cost specialty market.
2026 bond premium rate table
Here is what the premium runs across contract sizes and contractor profiles. These reflect standard-market schedules and SFAA guidance for 2026; specialty-market and SBA-backed rates run higher.
| Contract value | Well-qualified (strong financials) | Standard contractor | Newer / specialty market |
|---|---|---|---|
| $150,000 | ~$3,750 (2.5%) | ~$4,500 (3.0%) | $4,500 - $6,000 (3-4%) |
| $500,000 | ~$6,000 (1.2%) | ~$9,000 (1.8%) | $12,500 - $17,500 (2.5-3.5%) |
| $1,000,000 | ~$10,000 (1.0%) | ~$15,000 (1.5%) | $25,000 - $35,000 (2.5-3.5%) |
| $5,000,000 | ~$40,000 (0.8%) | ~$62,500 (1.25%) | Often unavailable |
| $10,000,000 | ~$70,000 (0.7%) | ~$115,000 (1.15%) | Requires strong balance sheet |
Notice the pattern: the well-qualified contractor pays a third to a half of what the newer contractor pays for the identical bond. That gap is not a fee, it is a penalty for a weak balance sheet, and it is fixable. When you build a bond premium into a bid, use your actual rate from your agent, not a rule of thumb, and run the whole markup through our markup and margin calculator so the bond cost does not quietly eat the margin you thought you had.
Bonding Capacity and How Underwriting Works
Bonding capacity is the total dollar amount of bonded work a surety will let you carry, and understanding how it is set is how you grow it.
How sureties set your capacity
Sureties underwrite on what they call the three Cs: capital, capacity, and character. Capital is your balance sheet, especially working capital (current assets minus current liabilities) and net worth. Capacity is your demonstrated ability to actually do the work, shown by your track record. Character is your reputation, references, and payment history. A common industry benchmark is that a surety will extend a single-job limit of roughly 10 times your working capital and an aggregate (total backlog) limit of about 20 times working capital. So a contractor with $200,000 in working capital might get a single-project limit around $2 million and an aggregate program around $4 million.
This is why undercapitalized contractors hit a ceiling fast. You can be the best builder in the county, but if your working capital is $50,000, your single-job bonding limit may be $500,000, and the $3 million jobs are simply off the table until you build capital.
The documents you need
Sureties want to see CPA-prepared financial statements (reviewed or audited for larger programs), a work-in-progress (WIP) schedule showing your current jobs and their percent-complete and profitability, a business plan, personal financial statements from the owners, and bank and supplier references. The quality of your financials directly moves your rate and your capacity. A sloppy, tax-basis statement from a bookkeeper tells the surety you do not run a tight shop; a clean, accrual-basis CPA statement with an accurate WIP tells them you know your numbers, and that lowers both your rate and your risk grade.
Getting Bonded as a Small Contractor
You do not need to be a giant to get bonded, but you do need to work the program deliberately. This is the path I have watched work.
Start with the SBA and specialty programs
The U.S. Small Business Administration's Surety Bond Guarantee Program backs bonds on contracts up to $9 million (and up to about $14 million on certain federal contracts) for small contractors who cannot yet qualify in the standard market, with the SBA guaranteeing 80% to 90% of the surety's loss. That guarantee lets a surety write a bond it would otherwise decline. Many first-time public contractors get their first several bonds through the SBA program or through specialty "contract bond" markets that price higher but say yes when the standard market says no. You pay a premium for it, but the first bonds build the track record that gets you into the cheaper standard market.
Build capacity deliberately
The move is to build capital and track record together. Retain earnings in the company rather than pulling every dollar out (working capital is the number that sets your limit), keep clean CPA financials, and complete a series of smaller bonded jobs on time and on budget so the surety has a track record to grade. Every completed bonded job without a claim moves your risk grade and your rate. Start on jobs comfortably inside your capacity rather than stretching to the biggest bond you can get, because one troubled project can wreck the reputation you are building. Public-works infrastructure work has predictable scopes that make good early bonded jobs; if you want to see the cost structures on those, our breakdowns of asphalt paving cost per square foot and excavation cost per cubic yard show where the margin lives on the trades that dominate early public bids.
Frequently Asked Questions
What is the difference between a performance bond and a payment bond?
A performance bond protects the project owner: if the contractor defaults, the surety completes the work or pays to have it finished. A payment bond protects subcontractors and suppliers: if the contractor fails to pay them, they claim against the bond rather than lien the property. Under the Miller Act, both are typically required at 100% of the contract value on federal jobs over $150,000.
How much do performance and payment bonds cost in 2026?
Bond premiums run 0.5% to 3% of the contract value, with the rate dropping as the contract grows and the contractor's financials strengthen. A well-qualified contractor on a $1 million job pays around 1% (about $10,000), while a newer or credit-challenged contractor can pay 2.5% to 3.5% (about $25,000 to $35,000) for the identical coverage.
At what dollar amount are bonds required on public works?
The federal Miller Act requires performance and payment bonds on federal contracts exceeding $150,000, with payment protection required between $35,000 and $150,000. State "Little Miller Acts" set their own thresholds, some as low as $25,000. Always confirm the exact threshold and required coverage percentage in the project solicitation.
How much bonding capacity can a small contractor get?
Sureties commonly extend a single-job limit of roughly 10 times your working capital and an aggregate limit of about 20 times working capital. A contractor with $200,000 in working capital might get a $2 million single-project limit and a $4 million total program. Capacity grows as you retain earnings and complete bonded jobs without claims.
How can a new contractor get bonded with no track record?
Start with the SBA Surety Bond Guarantee Program, which backs bonds on contracts up to about $9 million for small contractors who cannot yet qualify in the standard market, or use specialty contract-bond markets that price higher but approve more. Provide clean CPA financials and a work-in-progress schedule, start on smaller jobs inside your capacity, and build a claim-free track record that moves you into the cheaper standard market.
Your Action Item for This Week
Calculate your working capital right now: current assets minus current liabilities from your most recent balance sheet. Multiply it by 10 for your likely single-job bonding limit and by 20 for your aggregate limit. If those numbers are smaller than the public jobs you want to bid, your bottleneck is capital, not skill, and the fix is to build clean CPA financials and retain earnings before the next bid cycle. Then call a surety agent this week with those numbers in hand and ask exactly what rate and capacity they would extend, so your next public bid carries a real premium figure, not a guess. Run that premium through the markup and margin calculator to be sure the bond cost is priced into your margin and not against it.
