How to work it out

  1. Work out the discount: 40% of 80 = 0.4 × 80 = 32
  2. Take it off the price: 80 − 32 = 48
  3. Check: Add the saving back: 48 + 32 = 80.

Another method. In one step: you pay 60% of the price, so 0.6 × 80 = 48. Both methods always give the same answer.

In a spreadsheet: =80*(1-40%). 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 40% off, you pay 60% of the price: 48 instead of 80, a saving of 32.

Shopping: an item marked $80 with 40% off costs $48 at the till, before any sales tax.

Stacked discounts

40% off followed by another 40% off is 64% off in total, not 80%: the second discount applies to the lower price.
