This page opens the VAT calculator with India chosen as the country. The rate box shows 18%, and the quick picks are 18%, 5% and 40%. GST is a percentage added to a net price, so the sum is the same one the tool does for any tax.
To find the GST inside a price that already includes 18%, multiply the price by 18 and divide by 118. A total of ₹1,180 contains ₹180 of GST on a ₹1,000 net price. Rates can change, so confirm the rate for your goods or service with the tax authority.
How to add or remove VAT
- Type the amount, then choose your country for its rate, or type the rate or tap a quick pick.
- Choose Add tax for a net price, or Remove tax for a gross price.
- Read the net, tax and gross figures. The main answer is highlighted.
Questions
How do I find the GST inside a price that includes 5%?
Divide the total by 21. A price of ₹105 contains ₹5 of GST on a ₹100 net price. Tap 5%, choose Remove tax and type the total to see it worked out.
Why is the GST in an 18% inclusive price not 18% of it?
The 18% applies to the net price, not to the total. In ₹1,180 the GST is 18% of ₹1,000, which is about 15.3% of the total (18 ÷ 118).
What is the difference between net and gross?
Net is the price before tax. Gross is the price with the tax added on. Gross is always net plus the tax amount.
How do I add VAT to a price?
Multiply the net price by the rate written as a decimal, then add the result. At 20%, 100 × 1.2 = 120, so the tax is 20 and the gross price is 120.
How do I take VAT out of a price?
Divide the gross price by 1 plus the rate written as a decimal. Removing 20% from 120 gives 120 ÷ 1.2 = 100 net, and the tax is the difference, 20.
Is GST or sales tax worked out the same way?
The arithmetic is the same for any percentage tax added on top of a price. Which tax applies, which rate is right and how it is shown on an invoice depend on where you are, so check the official rules for your case.
