How Discounts Are Calculated
- Percent off: sale price = original × (1 − percent ÷ 100). $59.99 at 25% off = $44.99.
- Amount saved: original price − sale price.
- Spend & save coupon: the dollar discount stacks once per full spend threshold reached.
- Effective discount: amount saved ÷ original price × 100%, useful for comparing offers.
Quick Reference (Percent Off)
| Original | Percent off | Sale price | You save |
|---|---|---|---|
| $59.99 | 25% | $44.99 | $15.00 |
| $100.00 | 40% | $60.00 | $40.00 |
| $250.00 | 15% | $212.50 | $37.50 |
Sales tax is applied to the sale price, not the original price, so it is not included here.
Frequently Asked Questions
- How do I calculate a percent-off sale price?
- Sale price = original price × (1 − percent off ÷ 100). For example, $59.99 at 25% off = 59.99 × 0.75 = $44.99.
- How much do I save?
- Amount saved = original price − sale price. With a percent-off deal it equals original price × percent ÷ 100. A 25% discount on $59.99 saves $15.00.
- How does a “spend $X, get $Y off” coupon work?
- The discount applies once for each full $X you spend. On a $320 order with “spend $100, get $25 off,” the coupon applies 3 times for $75 off, making the price $245.
- What is the effective discount?
- Effective discount = amount saved ÷ original price × 100%. It lets you compare offers — for a $75 saving on $320, the effective discount is about 23.4% off.
