Sales tax / VAT calculator
Works both ways: add tax to a pre-tax price or back out tax from a tax-inclusive price. Works with any rate you need, US sales tax (typically 5-10%), UK VAT (20%), EU VAT (mostly 19-25%), Canadian GST/HST (5-15%), Australian GST (10%), and so on.
"Add tax" mode: enter the price without tax, get the total with tax and the tax amount on its own. Useful when you're quoting net prices and need a gross total.
"Remove tax" mode: enter what's on the receipt and see how much was the actual product and how much went to tax. Useful for expense tracking, accounting, and double-checking receipts.
This is also a full GST calculator for India (5%, 12%, 18%, 28%), Australia (10%), Singapore (9%), and other countries that call their consumption tax "GST". The formula is identical to VAT - just enter the rate that applies to your transaction.
How to use it
- Pick a mode: "add tax" (net to gross) or "remove tax" (gross to net).
- Enter the amount (pre-tax or after-tax, depending on the mode).
- Pick a tax rate by clicking one of the common-rate buttons (5%, 8%, 19%, 20%, 23%) or type your own.
- The result shows net, tax, and gross side by side, plus the formula used so you can sanity-check it.
When this is useful
Most common situations:
- Business invoicing. You have a pre-tax quote, you need to add tax for the customer. Enter net, get gross.
- Expense tracking and reimbursements. From a $123 receipt at 23%, you back out $100 net plus $23 tax. Useful for accounting and per diem calculations.
- Cross-border purchases. Importing from Germany (MwSt 19%), the UK (VAT 20%), or the US (sales tax varies by state). Handle every rate in one tool.
- Online sales. EU stores typically show prices with VAT (B2C) and often without (B2B). Quick conversion either way.
- Customer conversations. The customer got a "before tax" quote and asks "what's it with tax?". Answer in two seconds.
If you also need to apply a discount (e.g. "−15% off, then +VAT"), use our discount stacking calculator on top of the result.
