How to work it out

  1. Work out the discount: 75% of 20 = 0.75 × 20 = 15
  2. Take it off the price: 20 − 15 = 5
  3. Check: Add the saving back: 5 + 15 = 20.

Another method. In one step: you pay 25% of the price, so 0.25 × 20 = 5. Both methods always give the same answer.

In a spreadsheet: =20*(1-75%). Taking the percentage of the price gives the saving, not the price you pay. Subtract it, or multiply by the share that is left.

What the result means

After 75% off, you pay 25% of the price: 5 instead of 20, a saving of 15.

Shopping: an item marked $20 with 75% off costs $5 at the till, before any sales tax.

Stacked discounts

75% off followed by another 75% off is 93.75% off in total, not 100%: the second discount applies to the lower price.
