How to work it out

  1. Difference: 34 − 63 = -29
  2. Divide by the starting value: -29 ÷ 63 = -0.460317
  3. Multiply by 100: -46.0317%
  4. Check: Work forwards from the start: 63 × (1 − 0.460317) = 63 × 0.539683 = 34.

In a spreadsheet: =(34-63)/63*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 53.9683% of the old one: for every 100 at the start there are now 53.9683, so 46.0317 out of every 100 have gone.

Sales: a price cut from $63 to $34 is a 46.0317% discount.

Why the change back is different

A 46.0317% fall followed by a 46.0317% rise does not bring you back to 63: it gives 49.6508. The second percentage is taken of 34, not of 63, so to undo this change you need 85.2941% instead.
