Frequently asked questions

How do I extract VAT from a gross price?

Divide the gross amount by (1 + rate). The reverse-extract mode does this instantly and shows the net price and tax portion separately.

Do discounts apply before or after tax?

You choose — stacking supports both. Applying discounts before tax lowers the tax base; after tax lowers the payable total.

Is the VAT calculator free?

Yes, free with no signup, and multi-tier coupon stacking is built in.
