How to work it out

  1. Work out the discount: 20% of 25 = 0.2 × 25 = 5
  2. Take it off the price: 25 − 5 = 20
  3. Check: Add the saving back: 20 + 5 = 25.

Another method. In one step: you pay 80% of the price, so 0.8 × 25 = 20. Both methods always give the same answer.

In a spreadsheet: =25*(1-20%). 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 20% off, you pay 80% of the price: 20 instead of 25, a saving of 5.

Shopping: an item marked $25 with 20% off costs $20 at the till, before any sales tax.

Stacked discounts

20% off followed by another 20% off is 36% off in total, not 40%: the second discount applies to the lower price.
