Sales Tax and VAT Calculator

Use this sales tax and VAT calculator when you need to add tax to a base price or extract the tax portion from a total that already includes it. It works well for online shopping, invoices, quotes, budgeting, international purchases and quick checks before you pay.

Enter an amount and a manual tax rate, then choose whether you want to add tax or remove it from a tax-inclusive total. The tool returns the before-tax amount, the tax amount and the final total, which helps when a store lists prices before tax, a receipt uses VAT-inclusive pricing or you want to confirm a checkout number.

The result is a practical estimate, not tax advice. Real sales tax or VAT can vary by country, state, city, product type, exemptions and filing rules, so this tool is best used for manual calculation and fast verification.
