The Short Answer

What Is a Contractor Surety Bond?

Textbook Definition

A contract surety bond is a three-party guarantee. The surety promises the owner that the contractor will perform the contract and pay subs and suppliers. If the surety has to pay, the contractor must repay it.

In Plain English

A bond is a promise from a surety company that you will finish the job and pay your bills. The surety lends you its name. It will only do that if it believes in your numbers.

Why It Matters

Why Do Contractors Need Bonds?

Bonds are required on much public work. On federal construction contracts above $150,000, performance and payment bonds are required, and for contracts between $35,000 and $150,000 the contracting officer chooses alternative protections. Source: FAR 28.102-1. Florida’s Little Miller Act requires bonds on state work above $100,000, and local governments may exempt contracts of $200,000 or less. Source: Fla. Stat. 255.05.

Private owners and general contractors may ask for bonds too. Without one, you may be locked out of whole groups of jobs. A bond is also a test of your business: a surety that says yes has looked closely at your financials, your record, and your backlog.

A bond is not insurance. Insurance protects you. A bond protects the owner, and you owe the surety money if it has to pay. That is why sureties are careful. See the mandatory checklist for how bonds fit with licenses, insurance, and lien rights.

Signs you need to work on bonding:

  • You bid public work and cannot provide a bond.
  • You have lost a bid because you could not bond it.
  • Your financial statements are not prepared by an outside accountant.
  • You have no work-in-progress schedule.
  • Equipment debt is heavy compared with your working capital.
  • You have never met a surety agent.

The Fix

How to Get Bonded in 8 Steps

You can start before you need the bond. Sureties like to see a pattern, not a rush.

  1. Learn the three bond types.

    A bid bond guarantees you will sign the contract at your bid price and provide the other bonds. A performance bond guarantees you will finish the job. A payment bond guarantees you will pay your subs and suppliers.

  2. Know the three Cs.

    Sureties look at character, capacity, and capital. Character is your record and honesty. Capacity is your ability to do the work, shown by experience and people. Capital is your financial strength, mainly working capital.

  3. Get your financials in order.

    Plan on at least two years of financial statements. A CPA firm says that statements reviewed by an outside accountant are typical for bonds over $1 million. Add a work-in-progress schedule that lists each open job, its contract amount, cost to date, cost to complete, and billing, plus resumes for key people.

  4. Find an agent who works with contractors your size.

    A surety specialist is different from a general insurance agent. Ask about contractors similar to you, and meet before you need a bond.

  5. Understand your limits.

    New contractors may start with single-project limits of around $400,000, according to one CPA firm. Over time, limits grow with working capital and record. Rules of thumb vary: see the job-size guide.

  6. Know the cost.

    One broker says contractors with strong credit pay roughly 1% to 3% of the bond amount, middling credit 3% to 5%, and poor credit 8% to 10% or more. A Congressional Research Service report on the SBA program cites premiums of roughly 1.5% to 3.0%. Well-qualified contractors on larger contracts may pay below 1%. Your agent will quote you.

  7. Use the SBA program if the standard market says no.

    The SBA Surety Bond Guarantee backs sureties so they can say yes to smaller or newer contractors. The SBA guarantees up to 90% on contracts of $100,000 or less and on certain firms, and 80% on others. The contract cap is $9 million, or $14 million with federal certification, and quick bond approvals run up to $500,000.

  8. Keep your surety informed.

    Send updated statements and work-in-progress schedules on time, and call before there is a problem. Sureties remember who tells them early. For federal work, the surety must be listed on the Treasury’s Circular 570, last published August 1, 2026.

Worked Example: What a Premium Might CostA performance and payment bond on a $500,000 contract at an example rate of 2% costs about $10,000.At 3% it costs about $15,000. At 1.5% it costs about $7,500.Premium is a cost of the job. Put it in the bid. See how to bid a construction job.Illustration only. Your rate depends on your credit, financials, and the bond.

Check the Law for Your Job

Florida’s section 255.05 was amended in 2026 by a bill that, per its summary, exempts specified entities from some bond requirements. We could not read the changed text, so confirm the current thresholds before you rely on them. Other states set their own bond thresholds.

Dr. Paul’s Insight

Begin the bonding conversation a year before you need the bond. Clean statements, a written plan, and a record of paying your bills on time are what turn a no into a yes. A surety is the most patient lender you will meet, and the strictest. Pair this page with what lenders want because the packages overlap.

FAQ

Bonding Questions

How much does a surety bond cost for a contractor?
Rates depend on credit, financials, and the bond. One broker reports about 1 to 3 percent of the bond amount for strong credit, 3 to 5 percent for middling credit, and 8 to 10 percent or more for poor credit. SBA-program premiums are cited at roughly 1.5 to 3 percent. Your agent will quote you.
What do sureties look for in a contractor?
Character, capacity, and capital. In practice that means your record and honesty, your experience and people, and your financial strength. Expect to provide at least two years of financial statements, a work-in-progress schedule, and resumes.
How do I get bonded with little experience or weak credit?
Start with smaller bonds and a surety agent who works with new contractors, and ask about the SBA Surety Bond Guarantee. One CPA firm says new contractors may begin with single-project limits near $400,000. Build a record and your limits can grow.
What is a bid bond?
A bid bond guarantees that if you win, you will sign the contract at your bid price and provide the required performance and payment bonds. If you do not, the surety may owe the owner the difference up to the bond amount.
Are bonds required on private jobs?
Not by law in most cases, but some owners and general contractors require them by contract. Public jobs above certain thresholds usually require them. Check your state, the owner, and the contract.
