Add or remove VAT at any rate.
A VAT (Value Added Tax) calculator works out the tax portion of a price and separates the net (pre-tax) amount from the gross (tax-inclusive) amount. It handles both directions: adding VAT to a tax-exclusive price, or extracting the VAT already baked into a tax-inclusive price.
It is handy for invoicing, quoting, expense claims and shopping in VAT regions, where you often need to know how much of a total is tax versus the underlying goods or service value.
When removing VAT you must divide by (1 + rate/100), not simply subtract the percentage — subtracting the rate from a gross figure overstates the tax.
Because the percentage was applied to the smaller net figure, not the larger gross figure. To reverse it you divide the gross by (1 + rate/100). For example, ₹120 at 20% VAT has a net of ₹100, not ₹96.
Net is the price before VAT (what the seller keeps); gross is the price after VAT is added (what the customer pays). The difference between them is the VAT.
No — you enter the rate yourself, so it works for any VAT jurisdiction. Just use the rate that applies to your goods or services.
