Discount Calculator
How to calculate a discount quickly?
Knowing how much you are actually going to pay during sales helps you shop smarter. A discount is a percentage reduction from the original retail price.
Formula to get the final price
Our calculator uses the direct subtraction method to show you both the money you save and the final amount you will have to pay:
For example, if a jacket costs $60 and has a 20% discount: you calculate 20% of 60 (which is $12) and subtract it from the initial price (60 - 12 = $48).
The "multiplier factor" trick
If you want to do it mentally like an expert, multiply the original price by what remains after the discount. If something has a 30% discount, you pay 70% of its value. Just multiply the price by 0.70.
Common discount reference table
| Discount | Multiplier | Example: $100 item |
|---|---|---|
| 10% | × 0.90 | $90.00 |
| 15% | × 0.85 | $85.00 |
| 20% | × 0.80 | $80.00 |
| 25% | × 0.75 | $75.00 |
| 30% | × 0.70 | $70.00 |
| 50% | × 0.50 | $50.00 |
| 70% | × 0.30 | $30.00 |
Questions about Sales and Savings
What is a cumulative discount?
It occurs when a discount is applied to a product that was already on sale. The percentages are not added; the second discount is applied to the new, already reduced price. For example, 20% + 10% is not 30% — it is a 28% total discount.
How to know if a discount is real?
Always compare the crossed-out original price with the final price. Legally, shops must show the lowest price the product has had in the last 30 days before the promotion.
Is a fixed discount or a percentage better?
It depends on the amount. For expensive products, a percentage usually saves you more money. For cheap products, a fixed discount coupon (e.g., $5 off) can be more beneficial than 10%.
How to calculate what percentage has been discounted?
If you know the initial and final price, divide the savings by the original price and multiply by 100. For example, if something was $80 and now costs $60, the savings are $20 and the discount is (20 / 80) × 100 = 25%.
