How is ROI calculated?

It depends on context. Stock market averages 7-10% annually. Marketing campaigns often target 5:1 return. Compare against opportunity cost and industry benchmarks.

How do I compare investments of different lengths?

Use annualized ROI to compare. A 20% return in 6 months is better than 30% over 2 years. The calculator normalizes returns to annual rates.
