How to work it out

  1. Difference: 78 − 61 = 17
  2. Divide by the starting value: 17 ÷ 61 = 0.278689
  3. Multiply by 100: 27.8689%
  4. Check: Work forwards from the start: 61 × (1 + 0.278689) = 61 × 1.278689 = 78.

In a spreadsheet: =(78-61)/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 1.2787 times the old one: for every 100 at the start there are now 127.8689.

Prices: an item whose price rises from $61 to $78 has gone up by 27.8689%.

Why the change back is different

A 27.8689% rise followed by a 27.8689% fall does not bring you back to 61: it gives 56.2623. The second percentage is taken of 78, not of 61, so to undo this change you need 21.7949% instead.
