How it works
A discount reduces the selling price by a percentage of the original price: Final Price = Original Price × (1 − Discount%). Straightforward on a single item, but the arithmetic gets easy to fumble in your head when you're stacking a seasonal sale on top of an already-discounted clearance rack, or working out what percentage off you actually offered after the fact — which is what the second mode above solves, working backward from an original and sale price to the discount percentage.
The number worth checking before you run a promotion is what it does to your margin, not just the sticker price. A 20% discount on a product with a 30% margin cuts your profit on that sale by roughly two-thirds — a much bigger hit than the discount percentage alone suggests, since the discount comes straight out of what would have been profit.
A worked example: a $150 jacket at 30% off costs $105, a saving of $45. If a further 10% is taken off at the till, the price is $150 x 0.70 x 0.90 = $94.50, which is 37% off in total rather than 40%, because the second discount applies to the reduced price.
If you are the seller, check the effect on your profit before you set a discount. A discount comes straight out of your margin, so a small percentage can remove a large share of the profit on each sale.

Frequently asked questions
Q.How do I stack two discounts?
Apply them one after another, not by adding the percentages. A 20% discount followed by a 10% discount is not 30% off — run the first discount, then apply the second to the reduced price.
Q.Does a discount always mean lower margin?
Yes, unless your cost also drops. A 20% discount on a product with a 50% margin roughly halves your profit on that sale — worth checking before running a big promotion.
Q.Is this the same as a sale price calculator?
Yes — discount calculator, sale price calculator, and markdown calculator all describe the same tool: one that applies a discount percentage to a price, or reverses it to find the original price.
