GST and VAT rates, and how to back tax out
India's GST changed on 22 September 2025. The 12% and 28% slabs went, and most goods and services now fall into a 5% merit rate or an 18% standard rate. A 40% rate applies to a short list of luxury and sin items, such as larger cars and sugary aerated drinks, and many basic foods are at 0%. When a sale happens inside one state, the GST is split equally between central tax (CGST) and state tax (SGST). Between states it is one integrated tax (IGST) at the full rate.
In the UK, standard VAT is 20%, with a 5% reduced rate on things like home energy. Germany charges 19%, or 7% on most food and books. US sales tax is set by each state and city and is added at the till. A shelf price in the US normally excludes tax, while prices in India, the UK and the EU include it.
The mistake to avoid when removing tax is taking the rate off the total. Divide by one plus the rate instead. For a discounted item, tax is charged on the price after a discount shown on the invoice, so work out the discount first with the discount calculator. To share a bill that includes tax, use the bill splitter. For how much a price changed, try percentage change.

How this is calculated
Formula: Exclusive and inclusive tax
add: total =price × (1 + r) remove: price =total ÷ (1 + r)What the symbols mean
- rThe rate as a decimal, for example 0.18 for 18% GST.
Good to know
- India moved to two main GST slabs, 5% and 18%, with 40% on luxury and sin goods, from 22 September 2025.
- Inside one Indian state, GST splits evenly into CGST and SGST. Between states it is charged as IGST.
- Removing tax is not the same as taking the rate off the total: 20% VAT on a £120 total is £20, not £24.

Each example is worked out by the same code as the calculator above.
Adding 19% German VAT to €850
850 € × 1,19 = 1.011,50 €. The VAT is 161,50 €. Taking it back out: 1.011,50 € ÷ 1,19 = 850 €.
