How to work it out

  1. Work out the discount: 10% of 50 = 0.1 × 50 = 5
  2. Take it off the price: 50 − 5 = 45
  3. Check: Add the saving back: 45 + 5 = 50.

Another method. In one step: you pay 90% of the price, so 0.9 × 50 = 45. Both methods always give the same answer.

In a spreadsheet: =50*(1-10%). 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 10% off, you pay 90% of the price: 45 instead of 50, a saving of 5.

Shopping: an item marked $50 with 10% off costs $45 at the till, before any sales tax.

Stacked discounts

10% off followed by another 10% off is 19% off in total, not 20%: the second discount applies to the lower price.
