Tool guide

How to use the Sales Tax Calculator

The Sales Tax Calculator multiplies a pre-tax price by the tax rate to estimate tax, then adds that amount to the price. Rates and taxable items vary by jurisdiction, so the result is a planning estimate.

What this tool is useful for

Estimate tax before checkout.
Separate tax from the pre-tax price.
Compare totals under different local tax rates.

Practical example

At an 8.25% rate, tax on $100 is $8.25 and the estimated final price is $108.25.

Helpful tips

Use the combined rate that applies to the purchase location.
Some products and services are exempt or taxed differently.
Official invoices and checkout systems determine the actual amount owed.
