How sureties actually calculate your bond capacity

Surety bond underwriters use a formula. It's not magic. It's math.

Step 1: They calculate your adjusted working capital.
That's current assets minus current liabilities, minus AR aged over 90 days.
Step 2: They multiply that number.

Compiled statements: 10x for single jobs, 15x for total program

Reviewed statements: 12x single, 20x aggregate

Audited statements: 15x single, 25x aggregate

Step 3: They check your character and capacity.
Past project completion, key personnel, the type of work you've done before.

The single biggest lever in this whole equation is working capital. Most contractors get stuck at one bond tier because they distribute profits instead of retaining them. That's a slow build.

The faster move: a Line of Credit. Sureties view available LOC as a working capital reserve. Adding a $300K LOC effectively adds $300K to your working capital base. At a 15x multiplier, that's $4.5M in unlocked bond capacity.

You don't have to wait three years of retained earnings to crack the next bid tier. You can structure the capital today.
