How to work it out

  1. Difference: 61 − 45 = 16
  2. Divide by the starting value: 16 ÷ 45 = 0.355556
  3. Multiply by 100: 35.5556%
  4. Check: Work forwards from the start: 45 × (1 + 0.355556) = 45 × 1.355556 = 61.

In a spreadsheet: =(61-45)/45*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 1.3556 times the old one: for every 100 at the start there are now 135.5556.

Prices: an item whose price rises from $45 to $61 has gone up by 35.5556%.

Why the change back is different

A 35.5556% rise followed by a 35.5556% fall does not bring you back to 45: it gives 39.3111. The second percentage is taken of 61, not of 45, so to undo this change you need 26.2295% instead.
