Surety Bond Cost Calculator

How Much Will Your Surety Bond Cost?

The honest answer is "it depends." Surety bond pricing is driven by the type of bond, the bond amount, your personal credit, your business financials, and whether you're buying bonds one at a time or operating with a real bonding program. Most online bond calculators give you a single number, take your contact information, and call it done. That's the wrong way to shop for bonds.

Our calculator does something different. For performance and payment bonds, it shows you what a credit-only bond costs vs. what a program bond costs - side-by-side, on the same screen, with the dollar gap between them. That gap is real money. For most contractors bidding bonded work, it's the difference between paying retail and paying what real contractors pay.

What This Calculator Gets Right - and What It Doesn't

This calculator is built to give you a realistic ballpark, not a binding quote. Here's what it does well and where you should treat the output as a starting point.

What it gets right

• Realistic 2026 market rates, calibrated against what surety underwriters actually quote
• Side-by-side comparison of credit-only vs. program rates - the most important pricing decision contractors make
• Sliding-scale tier math for performance bonds (rate drops as contract size grows)
• Credit quality and contractor experience modifiers, because both meaningfully change your rate
• Multi-year discount math for license bonds (most state license bonds run on 2-year terms)

What it can't do

• It can't see your actual financial statements, your personal credit, or your project history. Real underwriting changes the number.
• It can't predict surety appetite for your specific trade, project type, or geography.
• It doesn't account for special situations - public-private partnerships, joint ventures, contracts with unusual terms, projects requiring backup sureties.
• It uses generalized industry rate ranges. Your actual quote depends on which surety market we place you in.

The number you see on this page is a starting point for the conversation, not the end of it. The real number requires real underwriting, and that requires the bond agent to know your business.

Credit-Only Bonds vs. Program Bonds - Why the Gap Is So Big

If you ran a $1,000,000 contract through the calculator with the "show me both" option, you saw two very different numbers. A credit-only bond at the standard 3% flat rate is $30,000. A program bond at standard market pricing for an established contractor is closer to $20,000-$23,000. A program bond at preferred pricing for a contractor with audited financials drops to roughly $11,500.

That's not a typo. The same bond, on the same project, can cost three times more or one-third less depending entirely on whether you have a bonding program and what tier you qualify for. Here's why.

Credit-only bonds price for risk the surety can't fully see

When a surety writes a bond based on personal credit alone, they don't have your financials, your work-in-progress schedule, your project history, or your banking relationships. They have your credit report and the bond application. To compensate for everything they can't see, they charge a flat 3% rate up to the $1,000,000 ceiling and require the contractor to indemnify the bond personally.

Credit-only bonds are useful. They get small contractors bonded fast. They handle one-off bid bonds when a program isn't built yet. But they're built for the surety's risk, not the contractor's wallet.

Program bonds price for the data the surety can see

A bonding program means the surety has reviewed your financials, your CPA-prepared statements, your work-in-progress, your bank reference, your project history, and your personal financial position. They've assigned you a credit tier - typically described as standard, preferred, or select - and your rate is set based on that tier rather than calculated from scratch on every bond.

The data lowers the surety's risk, and the lower risk shows up in your rate. Standard market program rates run roughly 1.5%-2.5% for most contract sizes. Preferred rates can drop to 0.6%-1.0%. The math compounds across every bonded job you do for the rest of the year.

The break-even is one or two bonded jobs per year

Building a bonding program isn't free. You need CPA-prepared financials, a current WIP, a banking relationship, and a continuity plan. For contractors who bid bonded work once a year or less, the math doesn't work yet - stick with credit-only or SBA-guaranteed bonds. For contractors bidding two or more bonded projects per year, a program pays for itself the first year and compounds every year after.

How Surety Bonds Actually Price

Surety bond pricing isn't arbitrary, but it isn't simple either. Here's the actual logic underwriters use to set your rate.

For license bonds and small commercial bonds

Most state contractor license bonds, plumbing license bonds, electrical bonds, and similar regulatory bonds price on a flat percentage of the bond face value, scaled by personal credit. Strong credit (FICO 750+) typically runs around 1% of the bond amount per year. Average credit (FICO 700-749) runs closer to 1.5%. Below that, rates climb meaningfully.

Multi-year terms get a discount. A two-year license bond doesn't cost twice the one-year price - it usually runs about 1.5x. Three-year terms run about 2x. Sureties offer the discount because the underwriting cost is largely paid once, regardless of term length.

Most license bonds carry a minimum premium of $100. Below that threshold, the rate calculation doesn't matter - the surety charges the minimum.

For performance and payment bonds

Performance and payment bonds price on a sliding scale tied to contract amount. The first dollars of a bond cost more (per dollar) than the last dollars. The pattern looks roughly like this for standard market pricing:

• First $100,000: ~3.0%
• $100,000 to $500,000: ~2.5%
• $500,000 to $2.5 million: ~2.0%
• $2.5 million to $5 million: ~1.5%
• $5 million to $7.5 million: ~1.25%
• Above $7.5 million: ~1.0%

For a $2 million contract, the math walks through each tier and adds up. The blended rate ends up around 2.15% for a standard-market established contractor, which is roughly $43,000 in premium on the $2,000,000 bond.

Then the credit quality multiplier and experience modifier adjust the number. A preferred contractor with audited financials might get a 0.5x multiplier - cutting the premium roughly in half. A first-time program contractor might pay 1.3x while they build track record. Sub-standard credit and SBA-guaranteed bonds run 1.25x.

For bid bonds

Most contract surety markets - including the ones Grit places business with - issue bid bonds at no cost when they're paired with a performance bond on the winning bid. Some markets charge a small admin fee ($100-$250) for standalone bid bonds. Compared to a bank Letter of Credit alternative (which typically costs 1-2% of the bid amount per year and ties up your operating credit), bond-based bidding is essentially free.

Frequently Asked Questions

How accurate is this bond cost calculator?
The calculator uses 2026 industry-standard rate ranges calibrated against what surety underwriters actually quote on standard market business. It's a realistic ballpark, not a binding quote. Real bond pricing requires real underwriting - your financials, your credit, your project history, and the surety market we place you with all change the final number. Treat the output as a starting point for the conversation.

Why does the calculator show two different prices for the same bond?
For performance and payment bonds, the calculator shows credit-only pricing alongside program pricing because they're two different underwriting paths. Credit-only bonds use your personal credit and a flat 3% rate up to $1 million. Program bonds use full underwriting (financials, WIP, banking, experience) and tier-based pricing that's typically much lower. The gap between the two is real money, and contractors should see it before they decide which path to take.

What's the highest bond I can get on personal credit alone?
The standard ceiling for credit-only contract surety bonds is $1,000,000. Above that, sureties require full underwriting with financials. Some markets cap credit-only bonds lower, particularly for contractors with limited bonded experience. If you need a bond above $1 million, the path is a bonding program.

What's the difference between a bid bond and a performance bond cost?
Bid bonds are usually free when paired with a performance bond from the same surety. Performance bonds carry the actual premium - typically 1% to 3% of the contract amount depending on contract size and your underwriting tier. Payment bonds (which protect subcontractors and suppliers) are usually issued together with the performance bond at no additional cost. The premium quoted is for the combined performance and payment bond protection.

Does my personal credit score really matter that much?
For credit-only bonds, yes - personal credit is the primary underwriting factor. For program bonds, personal credit is one factor among many (financials, WIP, experience, banking). Strong personal credit (FICO 700+) helps in both cases. Past credit issues don't automatically disqualify you, but they need to be explained, and the surety needs to see what's been resolved.

What is a bonding program and how do I get one?
A bonding program is an ongoing relationship with a surety that pre-approves your capacity for bonded work. Once a year, the surety reviews your financials, your work-in-progress, and your operations. They assign you a single job limit and an aggregate limit, and bonds inside those limits issue without re-underwriting every project. To qualify, you typically need CPA-prepared financials, a current WIP schedule, a bank reference, and a continuity plan. Our bond team helps contractors build programs from scratch.

Will the calculator give me a binding quote?
No. The calculator is an estimate tool, not a quote. Binding quotes require an application, underwriting review, and surety approval. The calculator gives you a realistic ballpark so you can budget the project and decide whether to proceed.

Are these rates the same for federal and state public works projects?
Federal projects (covered by the Miller Act) and state public works (covered by Little Miller Acts) follow the same general pricing logic. Some sureties have higher rates or stricter underwriting for federal projects, particularly very large federal contracts. The calculator output is a reasonable starting point for both, but federal-project pricing should be verified with the bond agent.
