How to work it out

  1. Difference: 90 − 17 = 73
  2. Divide by the starting value: 73 ÷ 17 = 4.294118
  3. Multiply by 100: 429.4118%
  4. Check: Work forwards from the start: 17 × (1 + 4.294118) = 17 × 5.294118 = 90.

In a spreadsheet: =(90-17)/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 5.2941 times the old one: for every 100 at the start there are now 529.4118. The value has more than doubled.

Prices: an item whose price rises from $17 to $90 has gone up by 429.4118%.

Why the change back is different

A 429.4118% rise followed by a 429.4118% fall does not bring you back to 17: it gives -296.4706. The second percentage is taken of 90, not of 17, so to undo this change you need 81.1111% instead.
