How to work it out

  1. Difference: 19 − 50 = -31
  2. Divide by the starting value: -31 ÷ 50 = -0.62
  3. Multiply by 100: -62%
  4. Check: Work forwards from the start: 50 × (1 − 0.62) = 50 × 0.38 = 19.

In a spreadsheet: =(19-50)/50*100. Always divide by the starting value, not the new one. A rise from 40 to 50 is +25%, but the fall from 50 back to 40 is −20%.

What the result means

The new value is 38% of the old one: for every 100 at the start there are now 38, so 62 out of every 100 have gone.

Sales: a price cut from $50 to $19 is a 62% discount.

Why the change back is different

A 62% fall followed by a 62% rise does not bring you back to 50: it gives 30.78. The second percentage is taken of 19, not of 50, so to undo this change you need 163.1579% instead.
