Sales Tax & VAT Calculator
Add tax to a price, or extract the tax already included in a total. Runs entirely in your browser. Nothing you type is ever uploaded.
What can you calculate?
TaxAdd adds a tax or VAT rate to a pre-tax price to get the total you'll pay, or runs the calculation backwards. Starting from a tax-inclusive total and working out the original pre-tax price and the tax amount hidden inside it.

How it works
Every calculation runs directly in your browser using plain arithmetic. Nothing is sent to a server, so it works even offline once the page has loaded.
Frequently asked questions
Is this free to use?
Yes. There's no sign-up and no limit on how many calculations you run.
Do you store what I type?
No. Every calculation happens entirely client-side in your browser. See the privacy policy for details.
What's the difference between the two modes?
"Add tax to a price" starts from a pre-tax price and adds the tax on top. "Extract tax from a total" does the reverse: you enter a price that already includes tax (common with VAT receipts) and it works out the pre-tax price and the tax amount hidden inside it.
Does this know my local tax rate?
No. Sales tax and VAT rates vary by country, state, and even product category, so you enter the rate yourself. Check your local tax authority for the exact rate that applies to you.
