How to work it out

  1. Difference: 97 − 51 = 46
  2. Divide by the starting value: 46 ÷ 51 = 0.901961
  3. Multiply by 100: 90.1961%
  4. Check: Work forwards from the start: 51 × (1 + 0.901961) = 51 × 1.901961 = 97.

In a spreadsheet: =(97-51)/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 1.902 times the old one: for every 100 at the start there are now 190.1961.

Prices: an item whose price rises from $51 to $97 has gone up by 90.1961%.

Why the change back is different

A 90.1961% rise followed by a 90.1961% fall does not bring you back to 51: it gives 9.5098. The second percentage is taken of 97, not of 51, so to undo this change you need 47.4227% instead.
