Sales Tax Calculator (Global VAT/GST) – Fast, Accurate, and Visual

What is sales tax (VAT/GST) and how do you calculate it worldwide?

Sales tax is a consumption tax charged on goods and services. Many countries use VAT or GST, which are value‑added taxes collected at each stage of the supply chain. Others apply retail sales taxes at the final sale. Despite naming differences, the practical method is the same: apply the combined percentage rate to the taxable base, then add the result to get your total due.

Core components of a correct sales tax bill

• Net price: Item subtotal multiplied by quantity, minus any discounts.
• Shipping/handling: Added to the order; taxable status varies by jurisdiction.
• Tax rates: VAT/GST (national), local/municipal, special/district, and import/customs where applicable.
• Inclusive vs. exclusive: Inclusive prices already contain tax; exclusive prices have tax added on top.

Reliable formulas for exclusive and inclusive pricing

Exclusive: Taxable base = Net price + taxable shipping. Tax total = Taxable base × Combined rate. Grand total = Net price + shipping + tax.

Inclusive: Net price = Inclusive total ÷ (1 + Combined rate) − non‑taxable shipping. Tax total = Inclusive total − Net price − taxable shipping. The calculator automates these steps and splits each tax component clearly.

Frequently asked questions

HOW TO calculate VAT from a total price that already includes tax?

Answer: Divide the total by (1 + total tax rate). The difference between the total and the net is VAT. The calculator does this automatically when Inclusive is enabled.

HOW TO know if shipping is taxable?

Answer: Check your local tax authority’s guidance. If taxable, select Yes so the tool includes shipping in the taxable base.

HOW TO handle multiple taxes (local + special + import)?

Answer: Enter each rate separately. The tool sums them and shows a slice for each in the 3D doughnut chart.

HOW TO apply both a discount amount and a discount percent?

Answer: The percent discount applies to the subtotal × quantity first, then the fixed amount is deducted. This prevents over‑discounting.

HOW TO round totals for receipts?

Answer: Use the Rounding option (0, 2, or 3 decimals) to match your invoicing convention.
