How to Use
Enter the original price and the discount percentage. The final price and savings amount are calculated instantly. The slider lets you quickly try different discount levels.
How Discount Calculation Works
The discount amount is calculated by multiplying the original price by the discount percentage divided by 100. The final price is the original price minus the discount amount. For example, 20% off $100: discount = $100 × 0.20 = $20, final price = $100 - $20 = $80.
Common Use Cases
- Calculating sale prices while shopping online or in stores.
- Comparing discount offers to find the best deal.
- Estimating bulk purchase savings with volume discounts.
- Planning budget with promotional discounts applied.
- Verifying advertised sale prices are correct.
Tips
- A 'buy one get one 50% off' deal equals 25% off the combined price.
- Stacked discounts (e.g., 20% + 10%) are not 30% — they compound to 28%.
- Compare the final price, not just the percentage, when evaluating deals.
- Some stores round up after applying discounts — verify the total at checkout.
- Use this calculator to quickly verify if a 'sale' price is actually a good deal.

FAQ
What is the difference between the savings amount and the final price?
The savings amount is the money taken off (original price × discount ÷ 100), while the final price is what you actually pay — the original price minus that savings. This tool shows both at the same time.
Are the prices and amounts I enter sent to a server?
No. All calculations run entirely in your browser. The prices and discount rates you enter are never sent to a server or stored anywhere.
Can it handle stacked discounts like '20% off, then 10% more'?
This tool applies a single discount rate. Stacked discounts compound to 28% rather than 30% (0.8 × 0.9 = 0.72). To handle them, take the result of the first discount and re-enter it as the new original price for the second.
Does it support currencies and taxes?
Amounts are treated as currency-agnostic numbers, so they work for dollars, yen, or any currency. Sales tax and fees are not included, so add them separately if you need a tax-inclusive total.
When should I use the slider versus typing the percentage?
The slider is handy for quickly sweeping the discount rate to see 'what would X% cost'. If you already know the exact rate, type it directly for precision. Either way, the result recalculates instantly.
