Sales Tax Calculator
The Sales Tax Calculator adds or removes sales tax, VAT, or GST at any rate, so you can find the tax amount, the pre-tax price, or the final total for any country or region.
Add or back out tax
To add tax, multiply the price by the rate and add it on. To find the pre-tax price from a tax-inclusive total, divide by (1 + rate). A $100 item at 8.25% sales tax costs $108.25; a $108.25 tax-inclusive price has a base of $100. The calculator does both directions for any custom rate.
Works anywhere
Because you set the rate yourself, it works for US state and local sales tax, UK and EU VAT, Indian GST, and any other consumption tax. It is handy for shoppers checking a receipt, and for sellers pricing items or preparing invoices.
Frequently Asked Questions
How do I find the price before tax?
Divide the tax-inclusive total by (1 + tax rate). For 8% tax, divide by 1.08; the difference is the tax portion.
Does it work for VAT and GST too?
Yes. You set any custom rate, so it works for US sales tax, VAT, GST, and other consumption taxes worldwide.
Can I calculate combined state and local tax?
Yes. Enter the total combined rate (state plus local) to get the correct tax and total.
Is sales tax added before or after discounts?
Typically tax is applied after discounts, on the reduced price. Enter the discounted price to reflect this.
