How to work it out

  1. Work out the discount: 40% of 50 = 0.4 × 50 = 20
  2. Take it off the price: 50 − 20 = 30
  3. Check: Add the saving back: 30 + 20 = 50.

Another method. In one step: you pay 60% of the price, so 0.6 × 50 = 30. Both methods always give the same answer.

In a spreadsheet: =50*(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: 30 instead of 50, a saving of 20.

Shopping: an item marked $50 with 40% off costs $30 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.
