GST and VAT Calculator
Enter an amount and a tax rate to see the breakdown.
This calculator works out GST or VAT in two directions. Add tax to a net price to see the gross total, or remove tax from a tax inclusive price to see the base amount and the tax portion. Enter your figure, set the rate, pick a mode, and read the breakdown.
How to use
- Enter the amount. In add mode this is the price before tax, in remove mode it is the price including tax.
- Type the tax rate as a percent, for example 18 for 18 percent.
- Choose Add tax or Remove tax from the mode selector.
- Read the base amount, the tax amount, and the total in the results panel.
Examples
- Add 18 percent GST to 1,000: base 1,000, tax 180, total 1,180.
- Remove 20 percent VAT from 120: base 100, tax 20, total 120.
- Add 5 percent GST to 250: base 250, tax 12.50, total 262.50.
FAQs
- What is the difference between add and remove mode?
- Add mode treats your amount as the price before tax and adds the tax on top. Remove mode treats your amount as a tax inclusive price and works backward to find the base and the tax already inside it.
- How do I remove GST or VAT from a total?
- Pick Remove tax mode and enter the tax inclusive total. The calculator divides it by 1 plus the rate over 100 to find the base, then subtracts to find the tax.
- Does it work for any tax rate?
- Yes. Enter any non negative percent. Common rates include 5, 12, 18, and 28 for GST, and 20 for VAT, but you can use any value that applies to you.
- Is the same formula used for GST and VAT?
- Yes. GST and VAT are both percentage taxes on a price, so the add and remove math is identical. Only the rate and the name differ by country.
- Are my numbers sent anywhere?
- No. The calculation runs entirely in your browser. Nothing you type is uploaded or stored.
