How to work it out

  1. Work out the discount: 40% of 10 = 0.4 × 10 = 4
  2. Take it off the price: 10 − 4 = 6
  3. Check: Add the saving back: 6 + 4 = 10.

Another method. In one step: you pay 60% of the price, so 0.6 × 10 = 6. Both methods always give the same answer.

In a spreadsheet: =10*(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: 6 instead of 10, a saving of 4.

Shopping: an item marked $10 with 40% off costs $6 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.
