How to work it out

  1. Difference: 92 − 91 = 1
  2. Divide by the starting value: 1 ÷ 91 = 0.010989
  3. Multiply by 100: 1.0989%
  4. Check: Work forwards from the start: 91 × (1 + 0.010989) = 91 × 1.010989 = 92.

In a spreadsheet: =(92-91)/91*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 1.011 times the old one: for every 100 at the start there are now 101.0989.

Prices: an item whose price rises from $91 to $92 has gone up by 1.0989%.

Why the change back is different

A 1.0989% rise followed by a 1.0989% fall does not bring you back to 91: it gives 90.989. The second percentage is taken of 92, not of 91, so to undo this change you need 1.087% instead.
