How to work it out

  1. Difference: 99 − 17 = 82
  2. Divide by the starting value: 82 ÷ 17 = 4.823529
  3. Multiply by 100: 482.3529%
  4. Check: Work forwards from the start: 17 × (1 + 4.823529) = 17 × 5.823529 = 99.

In a spreadsheet: =(99-17)/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 5.8235 times the old one: for every 100 at the start there are now 582.3529. The value has more than doubled.

Prices: an item whose price rises from $17 to $99 has gone up by 482.3529%.

Why the change back is different

A 482.3529% rise followed by a 482.3529% fall does not bring you back to 17: it gives -378.5294. The second percentage is taken of 99, not of 17, so to undo this change you need 82.8283% instead.
