How to work it out

  1. Difference: 94 − 77 = 17
  2. Divide by the starting value: 17 ÷ 77 = 0.220779
  3. Multiply by 100: 22.0779%
  4. Check: Work forwards from the start: 77 × (1 + 0.220779) = 77 × 1.220779 = 94.

In a spreadsheet: =(94-77)/77*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 1.2208 times the old one: for every 100 at the start there are now 122.0779.

Prices: an item whose price rises from $77 to $94 has gone up by 22.0779%.

Why the change back is different

A 22.0779% rise followed by a 22.0779% fall does not bring you back to 77: it gives 73.2468. The second percentage is taken of 94, not of 77, so to undo this change you need 18.0851% instead.
