Method and worked examples

The formula

Absolute change = current − prior. With a positive prior value, growth (%) = 100 × (current − prior) ÷ prior. FN2 does not display a growth percentage from zero or a negative baseline; the absolute change remains useful.

Quarter-on-quarter or year-on-year

For quarter-on-quarter growth, use the immediately preceding fiscal quarter. For year-on-year growth, use the corresponding fiscal quarter one year earlier. Name both periods. Do not compare a single quarter with a year-to-date total or mix periods of different lengths.

A worked example

Hypothetical revenue rising from 100 to 120 in identical units grows by 20, or 20%. Earnings moving from −10 to +5 improve by 15 and cross from loss to profit. Presenting that transition as ordinary percentage growth would be misleading, so this worksheet leaves the percentage unavailable.

Read beyond the percentage

Look for seasonality, acquisitions, currency effects and restatements in primary disclosures. If definitions changed, obtain a comparable series before interpreting the result. A percentage-point change in a margin is different from percentage growth in that margin; this worksheet is for changes in entered amounts.
