VAT / Sales Tax

About the VAT / Sales Tax

Adding or removing VAT, GST or sales tax trips up business owners and shoppers alike — and getting it wrong on an invoice means either short-changing yourself or overcharging a customer. The key is knowing that you add tax to a net price but divide to remove it from a gross one.

This VAT / Sales Tax calculator adds or removes tax at any rate and shows the net, tax and gross amounts clearly, so every invoice and price check is correct.

1. Enter the amount (net or gross).
2. Set the VAT, GST or sales-tax rate.
3. Choose whether to add tax or remove it.
4. See the net, tax and gross figures.

How the VAT / Sales Tax works

This calculator uses the established mathematical formulas that banks, lenders and financial institutions rely on — for interest, amortization, EMI, compounding, tax and investment growth. Where local rules apply (such as tax bands or GST/VAT rates), the tool follows the relevant published structure, and figures can be expressed in the currency you work in.

Every calculation runs in your browser, so the financial figures you enter stay completely private.

Tips & best practices

• To remove tax from a gross price you divide by one plus the rate — you cannot simply subtract the percentage, which is a common mistake.
• Always state on quotes and invoices whether a price includes tax, so customers are never surprised.
• Keep a note of the tax portion separately for your records and returns.

Standards & accuracy

Uses the same standard financial formulas as banks and lenders, with support for multiple currencies and international tax rules.

Disclaimer: results are estimates for general information only and are not financial advice. Rates, fees and tax rules change and vary by provider and jurisdiction. Confirm figures with your bank, lender or a qualified financial professional before making decisions.
