How to work it out

  1. Work out the discount: 30% of 25 = 0.3 × 25 = 7.5
  2. Take it off the price: 25 − 7.5 = 17.5
  3. Check: Add the saving back: 17.5 + 7.5 = 25.

Another method. In one step: you pay 70% of the price, so 0.7 × 25 = 17.5. Both methods always give the same answer.

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

Shopping: an item marked $25 with 30% off costs $17.5 at the till, before any sales tax.

Stacked discounts
