About this calculator
Prices on the shelf rarely include tax, so the number at the checkout is always a little higher than expected. This calculator adds sales tax to any price and shows both the tax amount and the total — useful for budgeting, expenses, or just avoiding surprises.
How it works
The tax is the price multiplied by the tax rate as a percentage. That amount is added to the original price to give the total. Enter your local combined rate (state, provincial or city) for an accurate figure.
Frequently asked questions
What tax rate should I use?
Use your local combined sales tax rate. It varies widely by country, state, province and even city, so check the rate that applies where you are buying.
Does this work for VAT or GST?
Yes — the math is the same. Enter your VAT or GST rate in the rate field.
Is the price before or after tax?
Enter the pre-tax price and the calculator adds the tax to give the total.
Can I use it for expenses?
Yes, it is handy for working out the tax portion of a purchase for budgets or expense claims.
