How to work it out

  1. Work out the discount: 15% of 50 = 0.15 × 50 = 7.5
  2. Take it off the price: 50 − 7.5 = 42.5
  3. Check: Add the saving back: 42.5 + 7.5 = 50.

Another method. In one step: you pay 85% of the price, so 0.85 × 50 = 42.5. Both methods always give the same answer.

In a spreadsheet: =50*(1-15%). 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 15% off, you pay 85% of the price: 42.5 instead of 50, a saving of 7.5.
