Use worked examples in technical articles
Teach the method with figures a reader can reproduce and adapt.
Pick inputs that reveal the decision
For ROAS, include spend, net revenue, and pre-ad contribution margin. A ratio-only example can hide whether a campaign makes money. Explain what every input includes so a reader can map it to their records.
Show a case where the answer changes
Hold ad spend and net revenue constant, then lower margin enough to cross break-even. This isolates why the recommendation changes. Keep the calculation visible and label fictional inputs as illustrative.
Check the example in the companion tool
Enter the same values and confirm that rounding and terminology agree. Give readers a clear next input to try. If a tool has limits, explain when a spreadsheet or more detailed model would better fit the decision.

Compare revenue per advertising dollar with the return needed to cover ad spend. Enter net revenue and contribution margin before ads.
