Discount and Coupon Order
The English calculator starts with percent off, the wording commonly used on sale signs and checkout pages. The result immediately restates the discount as the percentage of the original price you pay: 20% off means you pay 80%. Pay % remains available when that is the number you already know.
Advanced options let you switch whether the coupon is applied before or after the discount. If you only have a regular price and a sale price, open the reverse section to find the percent off directly.
| Input | Meaning | Example |
|---|---|---|
| Original price | The price before discount | $100 |
| Pay % | Enter the percentage of the original price you will pay | 80 means you pay 80%, which is 20% off |
| Percent off | Enter the amount reduced from the original price | 20 means 20% off |
| Coupon amount | A fixed amount subtracted according to the selected order | $10 coupon |
Sale Price Example
Suppose an item costs $120 and the discount rate means 25% off. The discounted price is $90. If a $10 coupon is applied afterward, the final estimated price is $80.
Real checkout systems can apply coupons, taxes, shipping, or exclusions differently, so use the result as a quick estimate before confirming the order.
| Step | Example | Result |
|---|---|---|
| Original price | $120 | $120 before discount |
| 25% off | $120 x 0.75 | $90 |
| Coupon after discount | $90 - $10 | $80 final estimate |
Use Discount Results for Unit Price Comparison
The discount calculator answers the first shopping question: what is the final price after the discount and coupon? The price comparison calculator answers the next question: which package is cheaper after comparing the same unit size?
| Question | Tool to use | Example |
|---|---|---|
| What is $100 at 15% off? | Discount Calculator | Choose % off and enter 15. |
| Which discounted package is cheaper? | Unit Price Calculator | Enter each final price and package size. |
| What percent off is this sale price? | Discount Calculator | Open the reverse section and enter the regular and sale prices. |
