How to work it out

  1. Difference: 83 − 21 = 62
  2. Divide by the starting value: 62 ÷ 21 = 2.952381
  3. Multiply by 100: 295.2381%
  4. Check: Work forwards from the start: 21 × (1 + 2.952381) = 21 × 3.952381 = 83.

In a spreadsheet: =(83-21)/21*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 3.9524 times the old one: for every 100 at the start there are now 395.2381. The value has more than doubled.

Prices: an item whose price rises from $21 to $83 has gone up by 295.2381%.

Why the change back is different

A 295.2381% rise followed by a 295.2381% fall does not bring you back to 21: it gives -162.0476. The second percentage is taken of 83, not of 21, so to undo this change you need 74.6988% instead.
