3. Summary
How is it calculated?
Savings equal original price times discount percent divided by 100. Sale price is original minus savings. A second discount stacks on the already-reduced price, not the original.

About discounts
A discount is a percentage taken off an original price. Sale price is what remains after that percentage is subtracted; savings equal Price × (Discount / 100). Example: 50 at 10% off is 45, savings 5. 100 at 25% off is 75. This is not a coupon stacker, not tax-inclusive VAT, and not a markdown calendar. Enter the list price and the percent off; the sale price and savings update as you type.
Common mistakes: applying a second discount to the original instead of the already-reduced price (stacking is sequential). Confusing 20% off with a 20% margin (Profit Margin Calculator). Entering the sale price in the original-price field. Limitations: no quantity breaks, no BOGO, no currency conversion.
