How to work it out

  1. Difference: 100 − 97 = 3
  2. Divide by the starting value: 3 ÷ 97 = 0.030928
  3. Multiply by 100: 3.0928%
  4. Check: Work forwards from the start: 97 × (1 + 0.030928) = 97 × 1.030928 = 100.

In a spreadsheet: =(100-97)/97*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 1.0309 times the old one: for every 100 at the start there are now 103.0928.

Prices: an item whose price rises from $97 to $100 has gone up by 3.0928%.

Why the change back is different

A 3.0928% rise followed by a 3.0928% fall does not bring you back to 97: it gives 96.9072. The second percentage is taken of 100, not of 97, so to undo this change you need 3% instead.
