GST / Tax Calculator — free online tool

Small businesses in GST or VAT regions split tax-inclusive receipts or add tax to a quoted net price. Works for any single percentage rate you type—not only Indian GST.

Cross-check anything that affects money or health with a qualified professional or official source.

How to use GST / Tax Calculator

  1. Choose whether your amount is tax-exclusive or already includes GST/VAT on the GST Calculator.
  2. Enter the base or inclusive amount and the tax rate percentage you need.
  3. Calculate to split net amount, tax component, and gross total.
  4. Cross-check against your invoice rules before filing—rates differ by country and product type.

Practical tips

  • Decide first whether your figure is tax-inclusive or exclusive—the two paths give different totals.
  • Works for any single rate (5%, 12%, 18%, VAT, sales tax), not only Indian GST slabs.
  • For multi-rate invoices, calculate each line separately rather than averaging the rates.

Example

Enter 1,000 exclusive and 18% GST to split net and tax on an invoice line item.

Limitations

GST / Tax Calculator uses simplified formulas. Tax brackets, bank rounding, leap seconds, and regional holidays are not modelled—confirm important totals with an official calculator or advisor.
