Discount Calculator
Enter an original price and a discount to see the final price, the amount saved, and your total savings percentage. You can add a second discount that applies after the first.
Applied after the first discount, the way stacked store discounts work.
How to use this tool
- 1Enter the original price of the item before any discount.
- 2Enter the first discount percentage. The final price, amount saved, and savings percentage update instantly.
- 3Optionally enter a second discount - this applies to the already-reduced price, not the original. Use this for stacked coupons or member discounts on sale items.
- 4Use the results to compare offers: check the total savings percentage to see the real combined discount.
Formula used
Example
Discount amount is 30. Final price is 90. You save 25%. Simple single-discount calculation for any sale item.
The first 20% discount brings the price to 80. The second 10% applies to 80, taking off 8 more, for a final price of 72. Total saved is 28, which is 28% off the original - not 30%. Two discounts never add linearly.
Common use cases
- Checking the real price of a sale item before going to the checkout
- Comparing a 30% sale vs a 20% + 15% coupon combination to find the better deal
- Calculating a wholesale discount on a trade price to confirm your margin
- Working out how much a loyalty member saves on a promotional price
- Checking what a 10% referral discount costs you in gross profit
Common mistakes
- Adding two discounts together - a 20% and a 10% discount is not 30% off. The second always applies to the reduced price, so the total is always less than the sum.
- Confusing percentage off with fixed amount off - '10% off' and '10 off' are different things at any price above 100.
- Forgetting that sales tax is separate - this calculator handles discounts only. If tax applies, use the Sales Tax Calculator on the final discounted price.
- Applying a coupon to an already-discounted price when the terms say it applies to original price only - check the offer terms before entering numbers.
Frequently asked questions
How do I calculate a percentage discount?
Multiply the original price by the discount percentage and divide by 100 to get the amount off, then subtract. For example, 25% off 120 is 30 off, leaving 90. The calculator does this instantly.
Do two stacked discounts add together?
No. A 20% then 10% discount is not 30% off. The first reduces the price to 80% of the original. The second takes 10% off that reduced price. On a 100 item, the final price is 72, saving 28%, not 30%.
Which is better: 30% off or 20% + 15% off?
30% off is always better than 20% + 15% stacked. The stacked version gives 20% + 12% (15% of the remaining 80%) = 32% of the original subtracted, making it 68 vs 70. Wait - 32% total savings is actually better. Always use the calculator to compare.
Does this add sales tax?
No. This tool handles discounts only. Discounts are applied first, then tax is added to the final price. Use the Sales Tax Calculator to add tax to the discounted price if needed.
How do I calculate a discount as a fixed amount off?
If you know the amount off but not the percentage, divide the discount by the original price and multiply by 100. For example, 15 off a 60 item is (15 / 60) x 100 = 25% off. Enter 25 as the percentage here.
What is the maximum discount I can give before losing money?
That depends on your margin. If your margin is 40%, you can discount up to 40% before breaking even (ignoring operating costs). Use the Profit Margin Calculator to find your margin first, then come back to check the discount impact.
Can I use this to calculate trade or wholesale discounts?
Yes. Enter the retail price and your trade discount percentage to see the trade price. Use the second discount field for an additional volume discount on top.
