How to use this calculator
- Enter the original price.
- Enter the percent-off offer and the dollar-off offer.
- See which one saves more, both final prices, and the break-even price.
Example: 20% off vs. $15 off
The better offer depends on the item price. At $75, 20% off saves $15, so both offers are equal.
Scroll the table horizontally if needed.
| Original price | 20% off | $15 off | Better offer |
|---|---|---|---|
| $50 | $10 saved | $15 saved | $15 off |
| $75 | $15 saved | $15 saved | Same |
| $100 | $20 saved | $15 saved | 20% off |
How to find the break-even price
Divide the dollar-off amount by the percentage as a decimal.
For 20% off and $15 off, $15 ÷ 0.20 = $75. Below $75, $15 off saves more. Above $75, 20% off saves more.
Check the offer details
This calculator compares straightforward discounts applied to the item price. A coupon may have a savings cap, minimum purchase, eligible-item restriction, pre-tax or post-tax rule, shipping cost, or limits on stacking with other offers. Check the terms before you buy.
Frequently asked questions
What if the dollar-off amount is more than the price?
Savings are capped at the original price, so this calculator never shows a negative final price.
Can I use decimals?
Yes. Prices, percentages, and dollar-off amounts can include decimals. Dollar amounts display to two decimal places.
What about an extra percentage off after another discount?
That is a different calculation because the second discount applies after the first one. Use the offer terms and compare the final checkout price.
