A fast three-step workflow
How to use the vat calculator
- 1
Enter the known information
Add only the values or source text the calculation needs. Useful examples and safe defaults are already selected.
- 2

Use the extra controls to match your real task instead of accepting a hidden one-size-fits-all assumption.
- 3
Review the complete result
Check the main answer, supporting values and method before copying, downloading or acting on the result.
What makes this tool more useful
Switch between a net price and a tax-inclusive price without manually reversing the percentage. Review the tax portion and alternative rates.
How the calculation works
Adding VAT multiplies the net amount by one plus the rate. Removing VAT divides the gross amount by that same factor.
Prepare invoices, verify receipts or compare tax-inclusive prices across rates.
Important financial information
This calculator provides an educational estimate from the values you enter. It does not use live prices, predict returns or provide investment, tax or legal advice. Verify exchange rules, fees, rates and product terms before making a financial decision.
Private, fast and mobile-ready
The workspace runs with browser JavaScript and does not submit entered values to a Rantey calculation endpoint. Controls use readable labels, large touch targets and responsive result panels for narrow screens.
