Worked example: a $250 purchase
Combined rate = 4.50% state + 4.56% average local = 9.06%
Sales tax = $250 × 0.0906 = $22.65 ($11.25 state, $11.40 local)
Total = $250 + $22.65 = $272.65
To back the tax out of a receipt total, divide by 1 plus the rate: $272.65 ÷ 1.0906 ≈ $250.00. The reverse sales tax calculator does this for any rate.
