## Overview (en)

The Discount calculator takes an original price and a discount percentage and returns the final price, the amount you save and the discounted price before tax. You can stack a second discount on the already reduced price and add a tax percentage on top. Every money amount is rounded half-up to the nearest cent.

## Questions (en)

### How are two stacked discounts calculated?

The second discount applies to the price after the first one, not to the original. The discounted price is price × (1 − first/100) × (1 − second/100), so 20% then 10% off 100 gives 72, a 28% total saving rather than 30%.

### Is sales tax applied before or after the discount?

After. The calculator first rounds the discounted price to the nearest cent, then multiplies it by (1 + tax/100) and rounds again. The You save figure is the original price minus the rounded discounted price, so tax is not counted as part of the saving.

### Can the discount be more than 100%?

No. Both the main discount and the optional second discount must be between 0 and 100%. Values outside that range produce an error, and the original price and tax percentage cannot be negative.
