Tax Calculator is an online tool that instantly calculates prices before and after tax, as well as tax amounts. It supports any custom tax rate, making it suitable for calculating VAT, sales tax, GST, or any other consumption tax worldwide. Choose from three rounding methods (round down, round up, or round), and easily convert prices in either direction - from pre-tax to post-tax or vice versa.
Tax rates vary significantly by country, state/province, and even by product type. To ensure accuracy, we let you enter the exact tax rate for your situation. Simply enter your local VAT, sales tax, GST, or any other rate.
'Round down' truncates fractions ($9.99→$9), 'round up' rounds to the ceiling ($9.01→$10), and 'round' uses standard rounding ($9.49→$9, $9.50→$10). Check with your local tax authority or business for the appropriate method.
Tax = Pre-tax price × Tax rate. Then rounding is applied to the tax amount, and post-tax price = pre-tax price + tax. For example, $100 × 10% = $10 tax, so $110 post-tax.
Pre-tax = Post-tax ÷ (1 + tax rate). For example, $110 ÷ 1.10 = $100 pre-tax. Rounding is applied to the tax amount.
