Worked example: a $250 purchase
Combined rate = 6.25% state + 2.73% average local = 8.98%
Sales tax = $250 × 0.0898 = $22.45 ($15.63 state, $6.82 local)
Total = $250 + $22.45 = $272.45
To back the tax out of a receipt total, divide by 1 plus the rate: $272.45 ÷ 1.0898 ≈ $250.00. The reverse sales tax calculator does this for any rate.
