Professional Sales Tax Calculations
Whether you're a business owner calculating VAT for an invoice or a shopper trying to find the pre-tax price of an item, our Sales Tax Calculator provides accurate results instantly. It handles both "Add Tax" (Exclusive) and "Remove Tax" (Inclusive) scenarios.
Tax Exclusive vs. Tax Inclusive
Tax Exclusive: The tax is added on top of the base price.
Formula: Total = Price + (Price × Tax Rate)
Tax Inclusive: The tax is already included in the displayed price. This is common with VAT and GST in many countries.
Formula: Pre-Tax Price = Total / (1 + Tax Rate)
Common Global Tax Rates (2026 Estimates)
- UK/EU VAT: Often 20%
- India GST: Varies (5%, 12%, 18%, 28%)
- USA Sales Tax: Varies by State (typically 0% to 10%)
Pro Tip: When using the "Remove Tax" mode, the calculator uses the mathematical reverse of the tax rate. A 20% inclusive tax is not the same as subtracting 20% from the total—it requires dividing by 1.20 to find the true original cost.
