Frequently Asked Questions
- What is a good ROI?
- A 'good' ROI depends on the context. Stock market investments historically average 7-10% annually. Real estate typically targets 8-12%. Marketing campaigns often aim for 5:1 return (400% ROI). Any positive ROI means the investment was profitable.
- What is the difference between ROI and annualized ROI?
- Standard ROI shows total return regardless of time. Annualized ROI adjusts for the holding period using the formula (1 + ROI)^(1/years) - 1, allowing fair comparison between a 50% return over 5 years and a 10% return over 1 year.
- Does ROI account for inflation?
- Basic ROI does not account for inflation. For inflation-adjusted returns (real ROI), subtract the inflation rate from your nominal ROI. For example, a 10% nominal ROI with 3% inflation yields approximately 7% real ROI.
What is a ROI Calculator?
Return on Investment (ROI) measures the profitability of an investment as a percentage of the original cost. It is one of the most widely used financial metrics for evaluating the efficiency of investments, comparing different opportunities, and making data-driven business decisions. ROI is calculated by dividing the net profit by the initial investment cost and multiplying by 100. A positive ROI indicates a profitable investment, while a negative ROI means a loss. The annualized ROI adjusts for the investment holding period, allowing fair comparison between investments held for different durations.
