What Is a Bid Bond?
A bid bond is a type of surety bond that guarantees your construction company will honor the terms of your bid if selected for a project. It protects project owners from contractors who submit low bids just to win contracts, then back out or inflate prices after being awarded the work.
When you submit a bid bond with your proposal, you’re making a financial promise that:
- ✅ You’ll enter into the contract if awarded the project
- ✅ You’ll provide required performance and payment bonds
- ✅ You won’t withdraw your bid or change pricing after acceptance
- ✅ Your bid accurately reflects your ability to complete the work
Bottom line: A bid bond shows project owners you’re a serious, qualified contractor backed by a surety company that has vetted your financial strength and capabilities.

How Bid Bonds Work: The Complete Process
The Three Parties Involved
👷 Principal
You (The Contractor)
Purchases the bond and submits bids for construction projects
🏛️ Obligee
The Project Owner
Government agency or private developer requiring the bond
🛡️ Surety
SwiftBonds/Insurance Company
Issues the bond and guarantees your performance
Step-by-Step: From Application to Award
You Apply for a Bid Bond
Submit your application with bid details, project information, and financial documents (if required for larger projects)
Underwriting Review
Our surety evaluates your creditworthiness, experience, and financial capacity. Projects under $250,000 qualify through our Fast Track program (24-hour approval).
Bond Issued
Once approved, we issue your bid bond digitally or mail physical forms. Your bond is typically FREE—no premium charged.
Submit Your Bid
Include the bid bond with your proposal to the project owner. The bond amount is usually 5-10% of your total bid.
Bid Opening & Award
If you win: You proceed to obtain performance and payment bonds and execute the contract.
If you don’t win: The bid bond expires with no further obligation.
Performance Phase
After contract award, the bid bond converts to performance and payment bonds (which do have premiums, typically 1-3% of contract value).
⚠️ Important: If you’re awarded the contract but fail to sign it or can’t provide the required performance bond, the project owner can claim against your bid bond. You’ll be liable to reimburse the surety for any payout.
How Much Does a Bid Bond Cost?
Good News: Bid Bonds Are FREE
At SwiftBonds, we don’t charge a premium for bid bonds. Here’s what you need to know about bid bond pricing:
Bid Bond Premium: $0 (FREE)
Most reputable surety providers don’t charge for bid bonds
Application Fee: $0
No hidden fees or processing charges
Bid Bond Amount: 5-20% of your bid
This is the bond penalty amount, not what you pay
💰 What You WILL Pay (If You Win)
Performance & Payment Bond Premiums
| Contract Size | Premium Rate |
| Under $500K | 1.5% – 3% |
| $500K – $2M | 1% – 2.5% |
| $2M – $10M | 0.8% – 2% |
| Over $10M | 0.5% – 1.5% |
*Rates depend on credit score, experience, and financial strength
Understanding Bid Bond Amounts vs. Premiums
Many contractors confuse the bid bond amount (the penalty limit) with the premium (what you pay). Here’s the difference:
Bid Bond Amount
$50,000
(10% of $500K bid)
This is the penalty amount the surety will pay if you default. It’s NOT what you pay for the bond.
Your Premium
$0
(FREE bid bond)
This is what you actually pay to get the bid bond. At SwiftBonds, bid bonds are always free.
Example: $500,000 Project Bid
| Your Bid Amount: | $500,000 |
| Bid Bond Required: | 10% = $50,000 |
| Cost for Bid Bond: | $0 (FREE) |
| If you win the contract: | |
| Performance Bond Amount: | 100% = $500,000 |
| Payment Bond Amount: | 100% = $500,000 |
| Total P&P Premium (2%): | $10,000 (one-time fee) |

Why Bid Bonds Help You Win More Projects
Bid bonds aren't just a requirement—they're a competitive advantage that helps you stand out and secure more work.
Access More Opportunities
Most government projects and many private jobs require bid bonds just to submit a proposal. Without bonding capacity, you can't even compete for these lucrative contracts. Being bondable immediately opens doors to:
- Federal construction projects (Miller Act requirements)
- State and municipal public works
- Large private commercial developments
- Infrastructure projects
Prove Your Credibility
A bid bond shows project owners that a third-party surety has vetted you. The surety company has:
- Reviewed your financial statements
- Verified your industry experience
- Confirmed your bonding capacity
- Determined you can handle the project
This external validation carries more weight than your own claims and helps you stand out against unbonded competitors.
Compete on Equal Footing
Bid bonds level the playing field by ensuring only serious, qualified contractors submit bids. Project owners know that:
- You have the financial backing to perform
- You won't submit a low-ball bid and walk away
- A surety company stands behind your commitment
- You can secure performance bonds if awarded
This eliminates fly-by-night competitors and positions you among reputable contractors.
Scale Your Business
Bid bonds are your first step toward larger, more profitable projects. As you successfully complete bonded work:
- Your bonding capacity increases
- You qualify for bigger contracts
- Your track record strengthens
- Better terms become available
Many contractors use bonding as a strategic growth tool, gradually taking on larger projects as their capacity expands.
When Are Bid Bonds Required?
| Project Type | Bid Bond Required? | Typical Bond Amount |
|---|---|---|
| Federal Projects (over $150K) | ✓ Always Required | 5-20% of bid |
| State/Municipal Projects | ✓ Usually Required | 5-10% of bid |

What Happens If You Default: Bid Bond Claims Explained
Understanding how bid bond claims work—and how to avoid them—is critical for protecting your business and bonding capacity.
When Can a Claim Be Filed Against Your Bid Bond?
Project owners can file a claim if you:
- 🚫 Withdraw your bid after being awarded the contract
- 🚫 Refuse to sign the contract after award
- 🚫 Fail to provide the required performance and payment bonds
- 🚫 Cannot meet the contract terms you bid on
- 🚫 Increase your pricing after bid acceptance
The Bid Bond Claims Process
| Step | What Happens | Your Obligation |
|---|---|---|
| 1. Default | You fail to honor your bid after contract award | Project owner notifies you and surety |
| 2. Claim Filed | Project owner submits formal claim to surety company | You receive notice and can respond |
| 3. Investigation | Surety investigates claim validity (usually straightforward for bid bonds) | Provide documentation if you have a defense |
| 4. Payout | Surety pays project owner the difference between your bid and next lowest bidder (up to bond amount) | N/A at this stage |
| 5. Indemnification | Surety demands reimbursement from you for the claim payment plus expenses | You must repay the surety in full |
⚠️ Critical: You Are Personally Liable
When you sign the indemnity agreement for a surety bond, you personally guarantee to reimburse the surety for any claims paid. This means:
- The surety can pursue your business assets
- The surety can pursue your personal assets
- You may face liens on property
- Your credit will be severely damaged
- Future bonding becomes extremely difficult or impossible
Example: How a Claim Works
Scenario: You bid $500,000 on a municipal project with a 10% bid bond ($50,000). After being awarded the contract, you discover you made a significant calculation error and cannot perform the work at that price. You attempt to withdraw.
What happens:
- Project owner awards contract to the next lowest bidder at $540,000
- Project owner files claim for the $40,000 difference
- Surety pays project owner $40,000 (within the $50,000 bond limit)
- Surety bills you for $40,000 + investigation costs (~$2,000) = $42,000 you must pay
- A claim record goes on your bonding history, making future bonds difficult/expensive
How to Prevent Bid Bond Claims
✓ Triple-Check Your Math
Review all cost calculations thoroughly before submitting. Have a second person verify your numbers. Most claims result from calculation errors.
✓ Confirm Your Bonding Capacity
Before bidding, verify with your surety that you can obtain the necessary performance bond if awarded. Don't bid on projects beyond your capacity.
✓ Understand Withdrawal Rules
You can withdraw BEFORE bid opening without penalty. Once bids open and you're selected, withdrawal triggers a claim. Know the timeline.
✓ Review Contract Terms
Make sure you fully understand all contract requirements, including performance bond amounts, insurance requirements, and timeline obligations.
✓ Include All Costs
Factor in ALL expenses: materials, labor, equipment, insurance, performance bond premiums, permits, and a reasonable profit margin.
✓ Work with Your Surety
Your surety wants you to succeed. Consult with them on large bids to ensure you're bidding appropriately and can be bonded if awarded.

💼 Understanding Your Bonding Capacity
Your bonding capacity is the maximum amount of work your surety will bond you for. It's based on:
- Working Capital: Current assets minus current liabilities
- Net Worth: Total assets minus total liabilities
- Experience: Track record of completed projects
- Current Work Load: How much bonded work you currently have
General Rule: Most sureties will bond you for 10x your working capital for a single project, and 15-20x your working capital in aggregate (all projects combined).
Example: If your working capital is $200,000, you might qualify for:
• Single project: Up to $2,000,000
• Total work bonded: Up to $3,000,000-$4,000,000
Frequently Asked Questions About Bid Bonds
Get answers to the most common bid bond questions
How much does a bid bond cost?
Most bid bonds are FREE from SwiftBonds and other reputable surety providers. While the bid bond itself typically has no cost, you should budget for the performance and payment bonds (usually 1-3% of the contract value) that will be required if you win the project. Some providers may charge a nominal processing fee of $100-$250, but at SwiftBonds, we don't charge for bid bonds.
How long does it take to get a bid bond?
For projects under $250,000, you can typically receive approval within 24 hours with our Fast Track program. For larger projects over $250,000, the underwriting process usually takes 2-5 business days depending on your financial documentation. We offer same-day approval for qualified contractors with complete applications. Digital bonds are delivered instantly upon approval, and we offer overnight shipping for physical bond forms if needed.
What happens if I win the bid but can't get a performance bond?
If you're awarded a contract but cannot obtain the required performance and payment bonds, the project owner can file a claim against your bid bond. The surety will pay the difference between your bid and the next lowest qualified bidder (up to the bid bond amount, typically 5-10% of your bid). You are then responsible for reimbursing the surety for this amount plus expenses. This can also damage your ability to obtain future bonds. That's why it's critical to work with your surety provider to ensure you can qualify for performance bonds before submitting bids.
Can I withdraw my bid after submission?
You can withdraw your bid before the bid opening without penalty. However, once bids are opened and you're awarded the contract, withdrawing will result in a claim against your bid bond. The project owner can collect the difference between your bid and the next lowest bidder. In rare cases, if you discover a genuine mathematical error in your bid before award, some project owners may allow withdrawal, but this is at their discretion and not guaranteed.
What's the difference between a bid bond and a performance bond?
A bid bond guarantees you'll honor your bid and enter into the contract if awarded. It's submitted with your proposal and protects the project owner during the bidding phase. A performance bond guarantees you'll complete the project according to the contract terms. It's obtained after you win the bid and protects the owner during construction. Think of it as: Bid bond = "Will you take the job?" Performance bond = "Will you finish the job?"
Do I need good credit to get a bid bond?
For smaller projects (under $250,000), good personal credit (typically 650+) is usually sufficient through our Fast Track program. For larger projects, underwriters also review your business financials, work history, and bonding capacity. While good credit helps, it's not the only factor. We work with contractors across the credit spectrum and can often find solutions even if your credit isn't perfect. The key is having solid experience and adequate working capital for the project size.
How is the bid bond amount determined?
The project owner sets the bid bond percentage in the bid documents, typically ranging from 5-20% of your bid amount. Federal projects under the Miller Act commonly require 20%, while most state and local projects require 5-10%. The percentage is designed to cover the potential cost difference if you default and they must award to the next lowest bidder. For example, on a $500,000 bid with a 10% requirement, you'd need a $50,000 bid bond.
Are bid bonds required for private construction projects?
Bid bonds are sometimes required for private projects, especially large commercial developments. While they're mandatory for most government work, private project owners have discretion. Large developers and sophisticated private owners often require bid bonds to ensure only serious, qualified contractors bid. Smaller private projects (like residential construction) rarely require them. Always check the bid documents to see if bonding is required.
