How to work it out

  1. Difference: 83 − 51 = 32
  2. Divide by the starting value: 32 ÷ 51 = 0.627451
  3. Multiply by 100: 62.7451%
  4. Check: Work forwards from the start: 51 × (1 + 0.627451) = 51 × 1.627451 = 83.

In a spreadsheet: =(83-51)/51*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 1.6275 times the old one: for every 100 at the start there are now 162.7451.

Prices: an item whose price rises from $51 to $83 has gone up by 62.7451%.

Why the change back is different

A 62.7451% rise followed by a 62.7451% fall does not bring you back to 51: it gives 30.9216. The second percentage is taken of 83, not of 51, so to undo this change you need 38.5542% instead.
