How to work it out

  1. Difference: 87 − 38 = 49
  2. Divide by the starting value: 49 ÷ 38 = 1.289474
  3. Multiply by 100: 128.9474%
  4. Check: Work forwards from the start: 38 × (1 + 1.289474) = 38 × 2.289474 = 87.

In a spreadsheet: =(87-38)/38*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 2.2895 times the old one: for every 100 at the start there are now 228.9474. The value has more than doubled.

Prices: an item whose price rises from $38 to $87 has gone up by 128.9474%.

Why the change back is different

A 128.9474% rise followed by a 128.9474% fall does not bring you back to 38: it gives -25.1842. The second percentage is taken of 87, not of 38, so to undo this change you need 56.3218% instead.
