How to Use the Sales Tax Calculator
Enter the pre-tax price and the applicable sales tax rate to see the tax amount and total price — or, working the other direction, enter a known tax-included total and the rate to back out the original pre-tax price and tax amount separately.
The Sales Tax Calculator works in both directions — here's how to use each mode.
Calculating tax and total from a pre-tax price
Enter the pre-tax price and the local tax rate — the calculator shows the tax amount and final total, useful for estimating the real cost of a purchase before reaching the register.
Working backward from a tax-included total
If you know only the final total paid and the tax rate, entering those lets the calculator back out the original pre-tax price and the exact tax amount — useful for expense reports or budgeting that need the pre-tax figure separated out.
