Find the sale price after one or two discounts, with optional tax.

About this calculator

Find the sale price after one or two percentage discounts, plus tax, and see how much you save.

Formula

Final price = Original × (1 − discount 1) × (1 − discount 2) × (1 + tax).

Example

A 200 item with 25% off costs 150 before tax; at 10% tax you pay 165.

Common questions

Are two discounts the same as one bigger discount?

No. 20% then 10% is 28% in total, not 30%, because the second discount applies to the lower price.

Is tax added before or after the discount?

Normally after, as this calculator does. Rules vary by country.
