Worked example: a $250 purchase

Combined rate = 4.22% state + 4.22% average local = 8.45%

Sales tax = $250 × 0.08445 = $21.11 ($10.56 state, $10.55 local)

Total = $250 + $21.11 = $271.11

To back the tax out of a receipt total, divide by 1 plus the rate: $271.11 ÷ 1.08445 ≈ $250.00. The reverse sales tax calculator does this for any rate.
