Full Rate Tier Comparison

Estimates based on typical surety market rates. Actual premiums vary by surety company, state, bond type, and individual underwriting. Always get multiple quotes.

How Bond Premiums Are Calculated

Your surety bond premium is calculated as a flat percentage of the bond's face value — the dollar amount your state requires. That percentage, called your rate, is set by the surety company based primarily on your personal credit score. You pay this rate annually to keep the bond active.

The premium is not what the surety will pay if a claim is filed. It is the annual fee for the surety's guarantee. The surety can pay up to the full bond face value on valid claims — and then pursue you personally for repayment under your indemnity agreement.

What Moves Your Rate

Factor	Direction	Impact
Credit score above 700	↓ Lowers rate	Access to 1–1.5% standard market rates
Credit score below 600	↑ Raises rate	5–15%; may require high-risk market surety
Prior paid bond claim	↑ Raises rate significantly	Often 3–5x standard rate; possible collateral requirement
Years in business (3+)	↓ Can lower rate	Demonstrated track record reduces perceived risk
Strong business financials	↓ Can offset poor credit	Effective for bonds over $50K where financials are reviewed
Bond amount over $100K	Triggers full underwriting	Requires financial statements; rate set case-by-case
Active bankruptcy	May block bonding entirely	Most sureties decline until discharge

Minimum Premiums

Most sureties charge a minimum annual premium regardless of what the percentage calculation produces — typically $75–$100. This means a $5,000 bond at 1% calculates to $50, but you'll likely pay the $75–$100 minimum. For very small bonds, the minimum premium is effectively your rate regardless of credit score.

Frequently Asked Questions

Is the premium I pay applied toward any claim? +

No. Your annual premium is the fee you pay for the surety's guarantee — it is separate from any claim payout. If a valid claim is paid, the surety pays up to the full bond face value out of their own funds, then pursues you personally for repayment under the indemnity agreement you signed. Your $150/year premium does not reduce or satisfy any claim obligation.

Can I get a lower rate mid-year if my credit improves? +

Generally no — premiums are set at the time of issuance and re-underwritten at renewal. If your credit score improves significantly between your bond issuance date and your next renewal, you can request re-rating at renewal and typically receive a lower rate if your score has improved. Some sureties will re-quote mid-term for major credit improvements, but this is the exception rather than the rule.

Why does the calculator show a range instead of an exact number? +

Different surety companies set their own rate tables within the same credit tier. Two sureties may both quote you for a 650 credit score but price your bond at 2.5% and 3.5% respectively — the market isn't uniform. The range reflects the realistic spread between the best and worst quotes you're likely to receive. Getting three quotes before committing is the practical way to find your actual low end.

Does shopping for quotes hurt my credit score? +

Some sureties run a soft pull for initial quoting (no score impact) and a hard pull only when you proceed to bind coverage. Others run a hard pull upfront. Ask before consenting. Multiple hard pulls for the same type of product within a 30-day window are typically treated as a single inquiry by most scoring models, so shopping around in a concentrated period minimizes any impact.
