Original price after 75% off
Enter what you paid and this page works back to the pre-sale price. The discount is fixed at 75% — the price is yours to change.
Worked example at 75% off
You paid £15.00 in a 75% off sale.
- 100% − 75% = 25% of the original price remains
- As a decimal that is 0.25
- 15 ÷ 0.25 = £60.00
- You saved £45.00
Check it forwards: £60.00 − 75% = £15.00 ✓
Adding 75% back to £15.00 would give £26.25 — which is wrong, and wrong by more as the percentage grows. The discount was taken off the larger original, so putting it back on the smaller sale price never reaches it.
Where 75% off shows up
Three quarters off is close to the practical floor for advertised retail discounts. Below this, stock is usually bundled, sold to a clearance house or written off rather than marked down further.
The arithmetic mirrors the 25% case exactly: you paid a quarter, so the original is four times what you handed over. A £15 item was ticketed at £60.

Doing it without a calculator
Multiply by four. You paid a quarter, so four times the sale price is the original exactly. On £15 that is £60. Like the 25% case it is one of the few depths you can reverse reliably in your head.
The exact method is always the same: divide by 0.25. 75% off leaves 25% of the original, so dividing by 0.25 undoes it precisely. Multiplying, or adding the percentage back on, gives a number that is always too small — and the error grows with the discount.
