FAQ
Does this calculator support tax-exempt items?
Yes. Enter a tax rate of 0% for exempt purchases to confirm the total matches the pre-tax price.
How do I handle different tax rates for multiple items?
Run the calculator separately for each rate or compute a weighted average rate before entering a combined value.
Can I reverse the calculation to find pre-tax price from a receipt?
Divide the total amount paid by (1 + tax rate ÷ 100) to isolate the pre-tax subtotal, then subtract to see tax paid.
Additional Information
- Total due = item price × (1 + sales tax rate ÷ 100).
- The calculator assumes a single combined rate; add local surtaxes to the percentage before running the calculation.
- If you need the pre-tax price from a total, divide the total by (1 + tax rate ÷ 100).
