About this VAT calculator
VAT (Value Added Tax) is a consumption tax added to many goods and services. Prices are often shown in two formats: net price (excluding tax) and gross price (including tax). Depending on the context (invoices, quotations, B2B pricing, accounting, budgeting, or e-commerce), you may need to convert net ↔ gross quickly and compute the VAT amount separately. This free VAT calculator helps you do that instantly with any VAT rate.
The formulas are straightforward. To go from net to gross, you add VAT using the rate: gross = net × (1 + rate). To go from gross back to net, you remove VAT by dividing: net = gross ÷ (1 + rate). Finally, the VAT amount is the difference: VAT = gross − net. This tool applies these formulas and displays all values clearly.
This calculator is useful when comparing supplier prices, checking receipts, preparing quotes, and verifying VAT on invoices. Keep in mind that real invoices can include rounding rules, multiple VAT rates on the same document, or additional fees. Still, this tool provides a fast and consistent baseline for everyday calculations.
