How to work it out

  1. Work out the discount: 30% of 80 = 0.3 × 80 = 24
  2. Take it off the price: 80 − 24 = 56
  3. Check: Add the saving back: 56 + 24 = 80.

Another method. In one step: you pay 70% of the price, so 0.7 × 80 = 56. Both methods always give the same answer.

In a spreadsheet: =80*(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: 56 instead of 80, a saving of 24.

Shopping: an item marked $80 with 30% off costs $56 at the till, before any sales tax.

Stacked discounts

30% off followed by another 30% off is 51% off in total, not 60%: the second discount applies to the lower price.
