What is ROI?
It is profit divided by the total outlay, expressed as a percent.
What is annualized ROI?
The ROI scaled to a per-year rate so periods can be compared.
Can ROI be negative?
Yes: when final value is below the amount invested.
Is my data sent to servers?
Never, it is computed locally in your browser.
Why is annualized ROI lower than simple ROI?
Because it spreads the total gain across the full holding period rather than treating it as one-time growth.
What is a good ROI?
It depends on risk and timeframe; compare against a broad index like the S&P 500 for context.
