Bid bonds are a fundamental requirement for public construction projects and many private works. Understanding how they work, what they cost, and how to obtain them is essential for any contractor looking to compete for government contracts.
What Is a Bid Bond?
A bid bond is a type of surety bond that guarantees a contractor will honor their bid if selected as the winning bidder. It protects the project owner from contractors who submit bids they cannot or will not fulfill.
The Three Parties Involved
| Party | Role | Responsibility | |-------|------|----------------| | Principal | Contractor submitting the bid | Must honor bid terms if selected | | Obligee | Project owner | Protected against bid withdrawal | | Surety | Bonding company | Guarantees contractor's obligation |
How Bid Bonds Work
- Contractor applies for bid bond from surety company
- Surety evaluates contractor's qualifications
- Bid bond is issued and submitted with proposal
- If contractor wins and refuses to proceed, surety pays damages
- Surety then recovers from contractor

Bid Bond Costs
Understanding bid bond pricing helps you budget accurately for projects.
Cost Structure
Bid bonds are typically issued:
- Free with performance/payment bond commitment
- Nominal fee ($100-500) as standalone
- Per-project basis or annual line
Factors Affecting Bond Costs
| Factor | Impact on Cost | |--------|---------------| | Company financials | Higher capital = lower rates | | Industry experience | More experience = lower rates | | Project type | Complex projects = higher rates | | Contract size | Larger contracts = lower per-dollar rates | | Geographic location | Some areas have higher rates |
Performance/Payment Bond Rates
Since bid bonds often come with P&P bonds, here are typical rates:
- Excellent credit: 0.5% - 1.5% of contract value
- Good credit: 1.5% - 2.5% of contract value
- Fair credit: 2.5% - 3.5% of contract value
Building Your Bonding Capacity
Growing your bonding capacity enables you to compete for larger projects.
Key Strategies
1. Strengthen Your Balance Sheet

2. Build a Track Record

3. Develop Key Relationships

4. Professional Financial Statements

Capacity Calculation Example
A surety might calculate your bonding capacity as:
| Metric | Value | Multiple | Capacity | |--------|-------|----------|----------| | Working capital | $500,000 | 10x | $5,000,000 | | Net worth | $750,000 | 15x | $11,250,000 | | Indicated capacity | | | $5,000,000 |
Capacity is typically limited by the lower calculation
Common Bid Bond Mistakes
Avoid these errors that can cost you contracts.
