How to work it out

  1. Difference: 84 − 65 = 19
  2. Divide by the starting value: 19 ÷ 65 = 0.292308
  3. Multiply by 100: 29.2308%
  4. Check: Work forwards from the start: 65 × (1 + 0.292308) = 65 × 1.292308 = 84.

In a spreadsheet: =(84-65)/65*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 1.2923 times the old one: for every 100 at the start there are now 129.2308.

Prices: an item whose price rises from $65 to $84 has gone up by 29.2308%.

Why the change back is different

A 29.2308% rise followed by a 29.2308% fall does not bring you back to 65: it gives 59.4462. The second percentage is taken of 84, not of 65, so to undo this change you need 22.619% instead.
