Worked example: a $250 purchase
Combined rate = 2.90% state + 4.99% average local = 7.89%
Sales tax = $250 × 0.0789 = $19.73 ($7.25 state, $12.48 local)
Total = $250 + $19.73 = $269.73
To back the tax out of a receipt total, divide by 1 plus the rate: $269.73 ÷ 1.0789 ≈ $250.00. The reverse sales tax calculator does this for any rate.
