Calculators
Calculate GST and VAT amounts instantly: add tax to a net price or extract embedded tax from a gross total. Supports custom global tax rates and displays tax-exclusive and tax-inclusive breakdowns.
Follow these simple steps to get instant, accurate results directly in your browser:
Type the numerical invoice amount in your active currency.
Choose a preset rate (5%, 12%, 18%, 28%) or enter a custom rate.
Select 'Add Tax' (Exclusive) or 'Remove Tax' (Inclusive) to inspect base price, tax amount, and total.
The GST & VAT Calculator provides forward (tax-exclusive) and reverse (tax-inclusive) sales tax and value-added tax computations across domestic and international tax schedules.
In forward tax calculations, the sales tax percentage is added to the base net amount to compute gross price and tax payable. In reverse VAT/GST calculations, the calculator mathematically isolates the embedded tax component from a gross total invoice using the inverse formula Base = Total / (1 + Rate / 100), ensuring that businesses and freelancers never miscalculate their tax liability.
The calculator respects the currency selected in your interface header without applying unexpected foreign exchange rate modifications. Calculations execute 100% locally in your browser memory.

Forward: Tax = Net * (Rate / 100) | Reverse: Net = Gross / (1 + Rate / 100)To add tax to a net amount: Multiply the net amount by the tax rate percentage. To extract embedded tax from a gross amount: Divide the gross amount by (1 + Rate/100) to find the net base, then subtract net from gross to find the tax.
Gross Total Receipt = $120.00 at 20% VAT Net Base Price = 120 / (1 + 0.20) = 120 / 1.20 = $100.00 VAT Amount = $120.00 - $100.00 = $20.00 (Notice tax is 20% of the $100 net base).
