Investment Risk & Return Analyzer
Analyze periodic investment returns, annualized performance, volatility, Sharpe ratio, drawdown, and growth of a hypothetical investment.
Paste or import a sequence of periodic returns to understand both the growth path and the variability along the way. The analyzer compounds the entered returns, estimates annualized geometric return and volatility, calculates a simple Sharpe ratio using your annual risk-free-rate assumption, and reports the maximum peak-to-trough drawdown.
date,return_pct. Return values are percentages per period: enter 2.5 for +2.5% and -1 for −1%. Use a consistent monthly, weekly, or daily series.Results

Method and limitations
Annualized return is the geometric growth rate implied by the full sequence and selected periods per year. Annualized volatility uses the sample standard deviation of periodic returns multiplied by the square root of periods per year. The Sharpe ratio uses arithmetic mean periodic return annualized minus the annual risk-free rate, divided by annualized volatility. Maximum drawdown is the largest decline from a previous cumulative peak in the observed path.
These estimates are sensitive to sample length, chosen frequency, and missing observations. They do not adjust for fees, taxes, external cash flows, survivorship bias, or benchmark differences. If your data contains deposits or withdrawals, use time-weighted periodic returns rather than changes in account balance.
A practical note on Investment Risk & Return Analyzer
The question worth answering: This page is most useful when you focus on reading return together with drawdown and variability. Comparing two strategies that report similar average returns but have different loss patterns. Start by recording the input source, the date or period covered, and any assumption you had to supply yourself. That makes the result easier to reproduce and helps another person understand what the output actually says.
How to use the result responsibly
Read the output alongside the inputs rather than as a stand-alone verdict. Change one assumption at a time and observe whether the conclusion changes materially. If the tool accepts a range, test more than one plausible case; if it accepts a file or pasted data, preserve an untouched copy of the original. Where the result will support a published claim or an important decision, keep a brief record of the method and source date.
A mistake specific to this kind of task
An average return alone hides sequence, volatility, downside tails and the possibility that the chosen period favours one strategy. This is why the output should be described as an estimate, diagnostic or comparison where appropriate—not as a guarantee. Avoid mixing currencies, periods, definitions or data sources merely because their labels look similar.
Independent check before acting
Use matched periods and currency, examine drawdowns and downside observations, and report the benchmark and return convention. If the result conflicts with a statement, official record, provider terms or the original dataset, investigate the difference before relying on it. The tool is intended to make a task clearer, not to replace the source system or professional advice when the consequences are material.
Reader takeaway: Keep the assumptions visible, verify the underlying evidence and use this result as one part of a reasoned decision.
