Calculate tax on any amount in four simple steps:
Gross = Net × (1 + Tax% / 100)
Multiply the net price by 1 plus the tax rate as a decimal. Example: $100 net with 20% VAT = $100 × 1.20 = $120 gross.
Net = Gross / (1 + Tax% / 100)
Divide the gross price by 1 plus the tax rate. Example: $120 gross with 20% VAT = $120 / 1.20 = $100 net.
Tax = Gross − Net
Subtract the net from the gross to find the tax portion. When adding: Tax = Net × Tax%. When extracting: Tax = Gross − (Gross / 1.Tax).
Multiplier = 1 + Tax% / 100
For 20% VAT, the multiplier is 1.20. To add tax, multiply by 1.20. To remove tax, divide by 1.20. This single number makes both directions easy.
Tax Fraction = Tax% / (100 + Tax%)
For 20% VAT: 20/120 = 1/6. So tax is exactly 1/6 of the gross price. This shortcut works for extracting tax quickly in your head.
Total = Net × (1 + R1/100) × (1 + R2/100)
When two taxes apply (e.g., federal + provincial), multiply sequentially. For Canada with 5% GST + 8% PST: multiply by 1.05 × 1.08 = 1.134.

Over 160 countries use VAT or GST systems. The EU has standardized VAT with rates from 17% (Luxembourg) to 27% (Hungary). The UK uses a 20% standard rate. Asian countries typically have lower rates — Japan at 10%, Australia and Singapore at 10% GST. The US is unique among developed nations in using a state-level sales tax system rather than a national VAT.
In VAT countries (UK, EU, Australia), prices displayed in shops typically include VAT — consumers see the final price. In sales tax countries (US), the displayed price excludes tax, which is added at checkout. This is why US shoppers often experience "sticker shock" at the register. Our calculator handles both systems with its two calculation modes.
Most countries have a registration threshold — a revenue level below which businesses do not need to charge VAT. In the UK, this is £90,000 (2024). In Australia, it's AUD $75,000. Below the threshold, businesses cannot charge VAT and also cannot reclaim input VAT, making tax calculation important for pricing decisions.
Many countries now impose VAT/GST on digital services (software, streaming, e-books) sold to consumers, regardless of where the seller is located. The EU, UK, Australia, and Japan all require foreign digital service providers to register and charge local VAT. Our calculator helps determine the correct tax-inclusive price for digital products in any market.
