What is the discount calculator?
It quickly shows the final price of a product after a percentage discount and how much the buyer saves. It is also built for store owners: enter your unit cost and the tool shows your profit before and after the discount, plus the extra sales you need to keep the same profit — so you know in advance whether a promotion is worth it.
How to use it
- Enter the original price.
- Enter the discount %, for example 20%.
- Optional: add an extra discount applied after the first one, as in “20% off + an extra 10%”.
- Optional: enter your cost per unit to see the impact on profit.
- Choose your currency; results appear instantly.
Why 20% + 10% is not 30% off
The second discount applies to the already-reduced price. A 100 item becomes 80 after 20% off; 10% of 80 is 8, so the final price is 72. The effective total discount is 28%, not 30% — shown in the “Effective total discount” box.
Discounts eat profit faster than you think
Take a product priced at 50 with a cost of 30: profit is 20. A 20% discount drops the price to 40 and the profit to 10. A 20% price cut halved your profit, and you must sell twice as many units (+100%) to earn the same total. That is why the tool shows this figure and warns you when a discount pushes you below cost.
When is a discount a good idea?
- To clear slow-moving stock that costs you storage.
- To acquire new customers likely to come back at full price.
- During peak seasons like Black Friday, Ramadan or back-to-school.
- For digital products with near-zero marginal cost, where profit stays high after a cut.
Smart alternatives to a straight discount
Instead of lowering the price, try free shipping above a threshold, a small gift with the order, or “buy 2, get the third half price”. These offers raise the average order value and protect your price positioning.
