How the discount is calculated
saving = original × 25/100
The arithmetic for a 25% discount: saving = price × 0.25; sale price = price − saving. On $79.00 the saving is $19.75 and the sale price is $59.25. For a quick estimate round the price first, then apply 25%.

A second discount on top of 25%
Stacked discounts do not add up. 25% off followed by a further 20% off is not 45% off; the second discount applies to the already reduced price, so the combined discount is 40%. On $79.00: $59.25 after the first discount, then $47.40 after the second.

| 25% then 10% more | 32.5% | $53.33 | 35% |
| 25% then 15% more | 36.3% | $50.36 | 40% |
| 25% then 20% more | 40% | $47.40 | 45% |

Reverse: from the sale price back to the original
Going backwards: if the sale price is $59.25 after 25% off, the original was $59.25 ÷ 0.75 = $79.00. Dividing by 0.75, not multiplying by 1.25, is the step people get wrong.
Mental math for 25%
For a seller, 25% off is only safe if the gross margin is above 25%. A product with a 25% margin sells at cost at this discount; a product with a 50% margin keeps 33.3% of the sale price after a 25% markdown.
