How to work out a sale price

1. Enter the original price and the discount.
2. Add a second discount if one applies on top, and the sales tax rate.
3. See the final price and how much you save.

Frequently asked questions

Is 20% off plus 10% off the same as 30% off?

No. The second discount applies to the already reduced price, so 20% and then 10% is 28% off in total.

How do I take a percentage off a price?

Multiply the price by 1 minus the discount: 80 with 25% off is 80 × 0.75 = 60.

Is sales tax added before or after the discount?

Usually after: the tax is worked out on the reduced price you actually pay.
