How to work it out

  1. Difference: 49 − 58 = -9
  2. Divide by the starting value: -9 ÷ 58 = -0.155172
  3. Multiply by 100: -15.5172%
  4. Check: Work forwards from the start: 58 × (1 − 0.155172) = 58 × 0.844828 = 49.

In a spreadsheet: =(49-58)/58*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 84.4828% of the old one: for every 100 at the start there are now 84.4828, so 15.5172 out of every 100 have gone.

Sales: a price cut from $58 to $49 is a 15.5172% discount.

Why the change back is different

A 15.5172% fall followed by a 15.5172% rise does not bring you back to 58: it gives 56.6034. The second percentage is taken of 49, not of 58, so to undo this change you need 18.3673% instead.
