よくある質問
What is a good ROI?
Context matters. A 7–10% annual ROI is strong for long-term investments; short-term campaigns may target 200%+ ROI. Compare against benchmarks for your sector.
Does ROI account for time?
Basic ROI does not. For time-weighted comparisons, use annualized ROI or CAGR instead.
