VAT / Sales Tax Calculator
Net or gross price in, tax and the other price out — no more guessing what to put on the invoice.
Tax is where small invoicing mistakes turn into real problems. This VAT and sales tax calculator handles both directions, because quotes and invoices do not always start from the same side. If you know the price before tax, enter it as the net price and the calculator adds the tax to give you the gross price your client pays. If you know the price your client will actually pay, enter it as the gross price and the calculator strips the tax back out to show the net amount you keep. Getting this backwards is the most common error: twenty percent on top of a net price is not the same as twenty percent taken off a gross price, and the difference comes straight out of your margin. The calculator also shows the tax amount itself, so you can check it against the line on your invoice before you send it. Rates, rules, and exemptions differ by country, region, and product, so always confirm the rate that applies to your sale. All calculations run in your browser and nothing is stored.

How to use the result
- Quoting before tax? Use the net price mode and show the client the gross total so there is no surprise at payment.
- Given a gross price? Use the gross price mode to find out how much you actually keep after tax.
- Put the tax amount on the invoice exactly as calculated, and check it against your accounting software before sending.
Frequently asked questions
Is VAT the same as sales tax?
Not exactly. VAT is charged at each stage of production with input-tax credits; sales tax is usually charged once at the final sale. The math here works for either when you know the rate.
Why is stripping tax out not the same as subtracting the rate?
Because the rate applies to the net price, not the gross price. To strip 20% tax out of a $1,200 gross price, divide by 1.20 to get $1,000 net — not subtract 20% of $1,200.
What tax rate should I use?
Use the rate that applies to your product, location, and customer type. Rates vary by jurisdiction and some goods are exempt or zero-rated. Check your local rules.
