The VAT Calculator converts between net price, VAT amount, and gross price using a rate supplied by the user. It supports both adding VAT to a tax-exclusive amount and extracting VAT from a tax-inclusive amount, which is useful for invoices, quotes, retail prices, and bookkeeping checks.
VAT rates and eligibility rules vary by jurisdiction and product category. The calculator performs arithmetic only; it does not decide whether a supply is taxable, exempt, zero-rated, or eligible for input-tax recovery.
Use the net amount for add mode or gross amount for extract mode.
Use the rate that applies to the transaction.
Enter 0 to add VAT or 1 to extract VAT from an inclusive price.
Check the net price, VAT amount, and gross price.
Confirm the correct rate and tax status with the relevant authority or adviser.
The rate is converted from a percentage to a decimal. Enter mode 0 when the amount excludes VAT and mode 1 when it already includes VAT.
The main result is an estimate based entirely on the values and rates entered. Use the supporting rows to see the taxable base and major components.
Results are planning estimates only. Tax rules, exemptions, filing obligations, and rates vary by jurisdiction and may change; verify the figures with the relevant tax authority or a qualified adviser.
Given: A net price of $1,000, VAT rate of 20%, and add mode.
Calculation: VAT = $1,000 × 20% = $200. Gross price = $1,000 + $200 = $1,200.
Result: VAT is $200 and the VAT-inclusive total is $1,200.
Add mode starts with a tax-exclusive price. Extract mode starts with a tax-inclusive total and separates the VAT portion.
Because the gross price already includes tax; the net amount must first be found by dividing by one plus the rate.
Yes. Enter the applicable percentage, including 0% where legally appropriate.
No. It only splits a transaction amount into net, VAT, and gross components.
The arithmetic is currency-neutral, although the display uses a dollar symbol for consistency.
