Discount & Sale Price Calculator
Sale tags show a percentage off, but the final price is not always obvious at a glance. This calculator applies a discount to an original price and shows both the sale price and your savings.
Enter the original price and the discount percentage. The calculator returns the sale price and the amount saved.
It is the quickest way to see what a "30% off" tag actually costs you at the till, and whether the saving is worth the impulse.
Enter your values to see the result.
How this is calculated
This calculator applies a percentage discount to an original price. The sale price is the original multiplied by (1 − discount percentage), and the saving is the original minus the sale price. A €80 item at 25% off becomes €60, saving €20.
For stacked discounts — a common retail tactic — the reductions apply in sequence, not by adding the percentages. A 20% discount followed by another 10% equals 28% off overall, not 30%, because the second discount applies to the already-reduced price.
The model is direct percentage arithmetic on a single price. It does not include sales tax or VAT on the discounted price (use the VAT calculator for that), minimum-spend conditions, bundle or "buy one get one" offers, or shipping costs that can erode the saving on online purchases.
Worked example
An €80 item marked 25% off.
- 1Sale price = 80 × (1 − 0.25) = 80 × 0.75 = €60.
- 2Saving = 80 − 60 = €20.
- 3With a further 10% off the sale price: 60 × 0.90 = €54, an overall saving of €26 (32.5% off, not 35%).
Frequently asked questions
- How is the sale price calculated?
- Sale price = Original × (1 − discount%). For a €80 item at 25% off, the sale price is €60 and the saving is €20.
- What about stacked discounts?
- Apply them in sequence, not by adding. A 20% discount followed by another 10% equals 28% off overall, not 30%.
- Is a bigger discount always a better deal?
- Only if you needed the item anyway. A 50% off something you would not otherwise buy is still 50% more than zero spent.
- How is the sale price calculated?
- Sale price = original × (1 − discount%). For an €80 item at 25% off, the sale price is €60 and the saving is €20. The discount always reduces the original price by that fraction.
- What about stacked discounts?
- Apply them in sequence, not by adding. A 20% discount followed by another 10% equals 28% off overall, not 30%, because the second discount applies to the already-reduced price.
