Use it when you want to test the exact inputs on this page: Add 20% VAT to a before-tax price. Remove 20% VAT from a tax-inclusive receipt total. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.
Amount means the price you already know. In add mode it is the net price; in remove mode it is the gross price. VAT rate means the tax rate entered as a normal percent, such as 20 for 20% or 5 for 5%. Mode means add VAT when the price is before tax, or remove VAT when the price already includes VAT.
Use add mode, enter 100 as the amount, and enter 20 as the VAT rate. The calculator shows $20 VAT and $120 gross.
Use remove mode, enter 120 as the amount, and enter 20 as the VAT rate. The calculator divides by 1.20, so the net amount is $100 and the VAT amount is $20.
Yes for the math if you enter the right UK rate yourself. GOV.UK lists 20% as the standard rate, with 5% reduced and 0% zero-rate categories, but the item or service still decides which rate applies.
No. The math can look similar on a receipt, but VAT and sales tax are different systems. If you are checking a U.S. sale, use the Sales Tax Calculator instead.
In plain language: To add VAT, the calculator multiplies net amount by the VAT rate, then adds that VAT amount to the net price. To remove VAT, it divides the gross price by one plus the VAT rate, then subtracts the net amount from the gross amount to find the VAT portion. For $100 at 20%, add mode multiplies 100 x 0.20 to get $20 VAT and $120 gross. For $120 with 20% included, remove mode divides 120 by 1.20 to get $100 net and $20 VAT.
Read net amount as the before-VAT price, VAT amount as the tax portion, gross amount as the price including VAT, and rate used as the percent entered.
This uses the manual VAT rate you enter. It does not choose the legal rate for a country, product, invoice, export, exemption, VAT registration threshold, reverse charge rule, or tax return. Use the official tax authority for the country, GOV.UK or EU VAT guidance when relevant, and a tax professional when registration, invoices, exemptions, cross-border sales, or returns matter.
Check the mode first. Add starts with net amount; remove starts with gross amount. Then check the rate, country, product type, invoice wording, exemption, reverse charge rule, and whether VAT or sales tax is the right system.
