How to work it out

  1. Difference: 42 − 17 = 25
  2. Divide by the starting value: 25 ÷ 17 = 1.470588
  3. Multiply by 100: 147.0588%
  4. Check: Work forwards from the start: 17 × (1 + 1.470588) = 17 × 2.470588 = 42.

In a spreadsheet: =(42-17)/17*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 2.4706 times the old one: for every 100 at the start there are now 247.0588. The value has more than doubled.

Prices: an item whose price rises from $17 to $42 has gone up by 147.0588%.

Why the change back is different

A 147.0588% rise followed by a 147.0588% fall does not bring you back to 17: it gives -19.7647. The second percentage is taken of 42, not of 17, so to undo this change you need 59.5238% instead.
