How to use it
In Sale price mode, enter the original price and the discount percentage. If there is an extra discount, such as a coupon, put it in the second discount field. You will see the sale price, the amount saved and the total discount as a percentage.
In Find discount % mode, enter the original and the current price and the calculator shows how many percent the price dropped. You can optionally add a tax rate and a currency symbol.
How it is calculated
- Sale price = original price × (1 − discount / 100).
- Two discounts are applied one after the other, not added together: 20% and then 10% off gives 28% in total, not 30%.
- Discount % = (original − sale) / original × 100.
- If you enter a tax rate, it is added to the sale price after the discounts.
