FAQs

1. What does ROI show in this calculator?

ROI shows profit earned relative to fully loaded marketing cost. It includes media spend and supporting costs, helping you judge real campaign profitability instead of revenue alone.

2. How is ROAS different from ROI?

ROAS compares revenue to ad spend only. ROI compares profit to all marketing costs. A campaign can have strong ROAS but weak ROI when fees, overhead, or low margins reduce profit.

3. Why should I include gross margin?

Gross margin converts revenue into contribution profit. Without margin, revenue can look healthy while the business still loses money after product cost, fulfillment, or service delivery expenses.

4. What is attribution credit used for?

Attribution credit lets you assign only part of the revenue to the campaign. It is useful when multiple channels influence the same sale and you need a more conservative view.

5. Should repeat purchase multiplier always exceed one?

Not always. Use 1.00 when you only want first-order value. Increase it when you have reliable repeat purchase evidence and want revenue estimates to reflect expected customer value.

6. Why does this calculator track CAC too?

CAC helps compare acquisition efficiency across campaigns, audiences, or channels. Using fully loaded CAC makes planning easier because it aligns conversion volume with total commercial effort.

7. What does breakeven conversions mean?

Breakeven conversions estimate how many conversions are needed to cover all included marketing costs at the current revenue quality, refund rate, and gross margin assumptions.

8. Can I export results for reporting?

Yes. After calculation, use the CSV or PDF buttons to download the campaign summary. This is helpful for internal reviews, client reporting, and budget planning discussions.
