In-depth explanation
VAT (Value Added Tax) is added to many goods and services. This calculator lets you add VAT to a net (ex-VAT) price or remove it from a gross (inc-VAT) price using a rate you choose — commonly the UK standard rate of 20%. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
To add VAT, multiply the net amount by (1 + rate). At 20%, £100 net becomes £120 gross (£100 × 1.2). The VAT portion is the difference: £20. To remove VAT from a gross price, divide by (1 + rate). £120 inclusive at 20% is £100 net (£120 ÷ 1.2).
The standard UK VAT rate is 20%. Some goods and services use reduced rates (such as 5%) or are zero-rated or exempt. This tool defaults to a standard rate you can change — it does not decide which category your product falls into. When in doubt, check HMRC guidance or your accountant.
US sales tax is usually added at the point of sale and rates vary by state and locality. You can model a common rate here for rough comparisons, but it is not a substitute for state filing tools. Invoices and receipts should always show the rate and tax amount your business actually charges.
