Toolstia / Sales tax calculator
Sales tax calculator
Enter a price and a tax rate to see the total with tax. Or go the other way: enter a tax-inclusive price and learn the price before tax and the amount of tax. Any rate works, so it suits sales tax, GST and similar taxes.
Enter an amount and a tax rate.
Use your local rate. Some places tax different goods at different rates, and some round each item rather than the total.
How it works
- Choose whether to add tax or find the tax in a price.
- Enter the amount and the tax rate.
- Read the price before tax, the tax and the total.
Adding tax
Tax is the price times the rate divided by 100. The total is the price plus the tax. A 100 item at 8% costs 108.
Finding the tax in a total
When the price already includes tax, divide it by 1 plus the rate to get the price before tax. For 108 at 8%, the price before tax is 100 and the tax is 8. Subtracting 8% of 108 would be wrong.
Rates vary
Rates differ by place and by type of goods. Use the rate printed on your receipt or from your tax authority.
Rounding
Shops may round tax on each item or on the whole bill, so a receipt can differ from this tool by a cent or two.
