How to work it out

  1. Work out the discount: 50% of 50 = 0.5 × 50 = 25
  2. Take it off the price: 50 − 25 = 25
  3. Check: Add the saving back: 25 + 25 = 50.

Another method. In one step: you pay 50% of the price, so 0.5 × 50 = 25. Both methods always give the same answer.

In a spreadsheet: =50*(1-50%). 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 50% off, you pay 50% of the price: 25 instead of 50, a saving of 25.

Shopping: an item marked $50 with 50% off costs $25 at the till, before any sales tax.

Stacked discounts

50% off followed by another 50% off is 75% off in total, not 100%: the second discount applies to the lower price.
