How to work it out

  1. Work out the discount: 70% of 25 = 0.7 × 25 = 17.5
  2. Take it off the price: 25 − 17.5 = 7.5
  3. Check: Add the saving back: 7.5 + 17.5 = 25.

Another method. In one step: you pay 30% of the price, so 0.3 × 25 = 7.5. Both methods always give the same answer.

In a spreadsheet: =25*(1-70%). 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 70% off, you pay 30% of the price: 7.5 instead of 25, a saving of 17.5.

Shopping: an item marked $25 with 70% off costs $7.5 at the till, before any sales tax.

Stacked discounts

70% off followed by another 70% off is 91% off in total, not 100%: the second discount applies to the lower price.
