Formula used
$$ ROI = rac{\text{Current Value} – \text{Cost}}{\text{Cost}} \times 100\% $$
ROI turns positive above 0 %, signalling profit (Investopedia, 2023).
Average annual S&P 500 ROI ≈ 10 % from 1957-2022 (S&P Dow Jones Indices Fact Sheet 2023).
Negative ROI means the asset lost value (SEC Investor Bulletin 2022).
ROI ignores holding time; use IRR for time-adjusted returns (CFA Institute Guide 2023).
FAQ
What does a positive ROI tell me?
A positive percentage shows your investment earned more than its cost, indicating profit and capital growth (Investopedia, 2023).
Can ROI be used to compare totally different assets?
Yes—because ROI is a percentage, you can rank stocks, real estate, or equipment on the same scale (CFA Institute Guide 2023).
Does the calculator include fees and taxes?
No. Input net figures if you want a post-expense ROI; otherwise the result reflects gross performance (IRS Publication 550 2022).
Why is time not part of the formula?
ROI captures size of gain, not speed; “add time-weighted metrics for rate-of-return insight” (Morningstar Methodology Note 2023).
What is a “good” ROI for long-term stocks?
Beating the historical S&P 500 average near 10 % annually is considered strong (S&P Dow Jones Indices Fact Sheet 2023).
How often should I recalculate ROI?
Quarterly reviews align with typical financial reporting cycles and capture market swings (SEC Investor Bulletin 2022).
