How to work it out

  1. Difference: 90 − 61 = 29
  2. Divide by the starting value: 29 ÷ 61 = 0.47541
  3. Multiply by 100: 47.541%
  4. Check: Work forwards from the start: 61 × (1 + 0.47541) = 61 × 1.47541 = 90.

In a spreadsheet: =(90-61)/61*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 1.4754 times the old one: for every 100 at the start there are now 147.541.

Prices: an item whose price rises from $61 to $90 has gone up by 47.541%.

Why the change back is different

A 47.541% rise followed by a 47.541% fall does not bring you back to 61: it gives 47.2131. The second percentage is taken of 90, not of 61, so to undo this change you need 32.2222% instead.
