How to work it out

  1. Difference: 51 − 47 = 4
  2. Divide by the starting value: 4 ÷ 47 = 0.085106
  3. Multiply by 100: 8.5106%
  4. Check: Work forwards from the start: 47 × (1 + 0.085106) = 47 × 1.085106 = 51.

In a spreadsheet: =(51-47)/47*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 1.0851 times the old one: for every 100 at the start there are now 108.5106.

Prices: an item whose price rises from $47 to $51 has gone up by 8.5106%.

Why the change back is different

A 8.5106% rise followed by a 8.5106% fall does not bring you back to 47: it gives 46.6596. The second percentage is taken of 51, not of 47, so to undo this change you need 7.8431% instead.
