How this service works
From a value series (or start/end/years): CAGR, total return, annualized volatility, Sharpe ratio (given risk-free) and maximum drawdown.
Output
Returns a structured JSON object containing: CAGR (compound annual growth rate as a percentage), total return (absolute percentage gain/loss), annualized volatility (standard deviation of returns scaled to annual), Sharpe ratio (risk-adjusted return given the supplied risk-free rate), and maximum drawdown (largest peak-to-trough decline in the series).
Example use cases
Portfolio performance review
“I have monthly NAV values for my portfolio over the last 3 years: [100, 103, 99, 107, 115, 111, 120, 118, 130, 125, 138, 142, 135, 148, 155, 152, 160, 165, 158, 170, 168, 175, 180, 178, 185, 190, 188, 195, 200, 205, 210, 208, 215, 220, 225, 230]. Can you compute the CAGR, total return, Sharpe ratio with a 4% risk-free rate, and max drawdown?”
Comparing two fund metrics
“I'm evaluating a fund that started at $50,000 and is now worth $87,000 after 5 years. What are the CAGR and total return? Also use a 3% risk-free rate for the Sharpe ratio.”
Volatility and drawdown for risk assessment
“Here are 12 monthly values for an ETF I'm analyzing: [200, 195, 210, 220, 215, 230, 225, 240, 235, 245, 250, 248]. Give me the annualized volatility, max drawdown, and Sharpe ratio assuming a 1.5% risk-free rate.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/return-cagr-drawdownWhen to prefer
Choose this endpoint when you need a complete set of standard investment return and risk metrics in a single call — especially CAGR, Sharpe ratio, and maximum drawdown together. It is ideal for portfolio analytics pipelines, fund evaluation workflows, or any agent task where the user wants a rigorous quantitative summary of an asset's historical performance. It accepts either a raw value series or simple start/end/years inputs, making it flexible for both detailed and summarized data sources.
Side effects
- Insufficient data points in the value series for meaningful volatility calculation
- Missing required inputs (no series and no start/end/years combination provided)
- Risk-free rate not provided when Sharpe ratio is requested
- Non-numeric or malformed values in the series causing computation errors
- Zero or negative values causing logarithmic return calculation failures
- Years value of zero causing division-by-zero in CAGR computation
