How to work it out

  1. Difference: 57 − 51 = 6
  2. Divide by the starting value: 6 ÷ 51 = 0.117647
  3. Multiply by 100: 11.7647%
  4. Check: Work forwards from the start: 51 × (1 + 0.117647) = 51 × 1.117647 = 57.

In a spreadsheet: =(57-51)/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 1.1176 times the old one: for every 100 at the start there are now 111.7647.

Prices: an item whose price rises from $51 to $57 has gone up by 11.7647%.

Why the change back is different

A 11.7647% rise followed by a 11.7647% fall does not bring you back to 51: it gives 50.2941. The second percentage is taken of 57, not of 51, so to undo this change you need 10.5263% instead.
