How to work it out

  1. Work out the discount: 25% of 100 = 0.25 × 100 = 25
  2. Take it off the price: 100 − 25 = 75
  3. Check: Add the saving back: 75 + 25 = 100.

Another method. In one step: you pay 75% of the price, so 0.75 × 100 = 75. Both methods always give the same answer.

In a spreadsheet: =100*(1-25%). 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 25% off, you pay 75% of the price: 75 instead of 100, a saving of 25.

Shopping: an item marked $100 with 25% off costs $75 at the till, before any sales tax.

Stacked discounts

25% off followed by another 25% off is 43.75% off in total, not 50%: the second discount applies to the lower price.
