How to work it out

  1. Work out the discount: 25% of 20 = 0.25 × 20 = 5
  2. Take it off the price: 20 − 5 = 15
  3. Check: Add the saving back: 15 + 5 = 20.

Another method. In one step: you pay 75% of the price, so 0.75 × 20 = 15. Both methods always give the same answer.

In a spreadsheet: =20*(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: 15 instead of 20, a saving of 5.

Shopping: an item marked $20 with 25% off costs $15 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.
