How to work it out

  1. Difference: 99 − 24 = 75
  2. Divide by the starting value: 75 ÷ 24 = 3.125
  3. Multiply by 100: 312.5%
  4. Check: Work forwards from the start: 24 × (1 + 3.125) = 24 × 4.125 = 99.

In a spreadsheet: =(99-24)/24*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 4.125 times the old one: for every 100 at the start there are now 412.5. The value has more than doubled.

Prices: an item whose price rises from $24 to $99 has gone up by 312.5%.

Why the change back is different

A 312.5% rise followed by a 312.5% fall does not bring you back to 24: it gives -210.375. The second percentage is taken of 99, not of 24, so to undo this change you need 75.7576% instead.
