How to work it out

  1. Difference: 83 − 78 = 5
  2. Divide by the starting value: 5 ÷ 78 = 0.064103
  3. Multiply by 100: 6.4103%
  4. Check: Work forwards from the start: 78 × (1 + 0.064103) = 78 × 1.064103 = 83.

In a spreadsheet: =(83-78)/78*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 1.0641 times the old one: for every 100 at the start there are now 106.4103.

Prices: an item whose price rises from $78 to $83 has gone up by 6.4103%.

Why the change back is different

A 6.4103% rise followed by a 6.4103% fall does not bring you back to 78: it gives 77.6795. The second percentage is taken of 83, not of 78, so to undo this change you need 6.0241% instead.
