- What counts as cost in ROI?
- Fully-loaded spend: media, creative production, agency fees, incremental tooling, and human time if you capitalize labor. Exclude sunk costs unrelated to the initiative or you bias ROI downward. For this guide, check the formulas, examples, and source links on the page before relying on the result. The main risk is using the right calculation with the wrong base, date, tax rule, or cost definition, which can produce a confident but misleading number.
- Should ROI include opportunity cost?
- Classic ROI often ignores opportunity cost unless you explicitly model it as an alternative investment return. For strategic finance, scenario tables beat a single ratio. For this guide, check the formulas, examples, and source links on the page before relying on the result. The main risk is using the right calculation with the wrong base, date, tax rule, or cost definition, which can produce a confident but misleading number.
- How is ROI different from ROAS?
- ROAS is revenue divided by ad spend for media efficiency. ROI should subtract cost of goods and variable fulfillment to reflect margin, not top-line revenue. For this guide, check the formulas, examples, and source links on the page before relying on the result. The main risk is using the right calculation with the wrong base, date, tax rule, or cost definition, which can produce a confident but misleading number.
- Can ROI be negative?
- Yes, when gain is less than cost. Report negative ROI clearly rather than clamping to zero - otherwise you hide losing experiments. For this guide, check the formulas, examples, and source links on the page before relying on the result. The main risk is using the right calculation with the wrong base, date, tax rule, or cost definition, which can produce a confident but misleading number.
- How do I handle multi-touch attribution?
- ROI per channel gets fuzzy when journeys are blended. Use incrementality tests or holdouts when budget allows; otherwise label ROI as 'model-dependent' in footnotes. For this guide, check the formulas, examples, and source links on the page before relying on the result. The main risk is using the right calculation with the wrong base, date, tax rule, or cost definition, which can produce a confident but misleading number.
- Is Toollabz ROI output audited?
- It performs the arithmetic you supply. It does not fetch your analytics APIs or verify finance system numbers. For this guide, check the formulas, examples, and source links on the page before relying on the result. The main risk is using the right calculation with the wrong base, date, tax rule, or cost definition, which can produce a confident but misleading number.
