How to work it out

  1. Work out the discount: 75% of 40 = 0.75 × 40 = 30
  2. Take it off the price: 40 − 30 = 10
  3. Check: Add the saving back: 10 + 30 = 40.

Another method. In one step: you pay 25% of the price, so 0.25 × 40 = 10. Both methods always give the same answer.

In a spreadsheet: =40*(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: 10 instead of 40, a saving of 30.

Shopping: an item marked $40 with 75% off costs $10 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.
