20% Off 50

20% off 50 = 40 (you save 10)

How to calculate 20% off 50

  1. Find the discount: 20% of 50 = 0.2 × 50 = 10.
  2. Subtract it from the price: 50 − 10 = 40.

Or in one step, multiply by the share you pay: 50 × 0.8 = 40.

Stacked discounts do not add up: an extra 10% off the sale price gives 36, which is 28% off in total, not 30%.
