Frequently Asked Questions
How do I calculate sales tax?
Multiply the pre-tax price by the tax rate divided by 100. For example, $50 at 8% tax: $50 × 0.08 = $4 tax, $54 total.
How do I find the pre-tax price from a total?
Divide the total by (1 + tax rate / 100). For example, a $54 total at 8% tax: $54 ÷ 1.08 = $50 pre-tax price. Use the reverse calculator above.
