How to work it out

  1. Difference: 68 − 42 = 26
  2. Divide by the starting value: 26 ÷ 42 = 0.619048
  3. Multiply by 100: 61.9048%
  4. Check: Work forwards from the start: 42 × (1 + 0.619048) = 42 × 1.619048 = 68.

In a spreadsheet: =(68-42)/42*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 1.619 times the old one: for every 100 at the start there are now 161.9048.

Prices: an item whose price rises from $42 to $68 has gone up by 61.9048%.

Why the change back is different

A 61.9048% rise followed by a 61.9048% fall does not bring you back to 42: it gives 25.9048. The second percentage is taken of 68, not of 42, so to undo this change you need 38.2353% instead.
