A headline about rising revenue does not tell you whether profit rose. Different business measures answer different questions. This fictional numerical example is a public financial literacy exercise, not a company recommendation or competition investment strategy.

Keep the measures separate
Suppose a fictional business reports revenue of 100 and profit of 10 in one period. In the next comparable period, revenue is 120 and profit is 9. Both periods use the same currency units and the same profit definition.
Revenue increased by 20 on a base of 100, so revenue growth is 20%. Profit fell by 1 on a base of 10, so profit growth is -10%. The two directions are different.
Calculate the margin
The first profit margin is 10/100 = 10%. The second is 9/120 = 7.5%. Margin has fallen by 2.5 percentage points.
Relative to the original 10% margin, that is a 25% decrease in the margin. A change in percentage points and a percentage change are different descriptions; write the denominator when calculating either.
Ask what could explain the difference
Costs may have risen faster than revenue, but these two headline figures do not identify the specific cause. Pricing, product mix, expenses and the definition of the reported profit measure could all require investigation.
Check that periods are comparable and that one measure has not been changed between reports. A number labelled adjusted profit may not have the same definition as another profit figure.
Use the figures to form questions
Good reading separates the calculation from its explanation. The calculation establishes what changed; additional evidence is needed to explain why it changed or what may happen next.
