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 JSON object containing: CAGR (compound annual growth rate as a percentage), total return (percentage), annualized volatility (standard deviation of returns annualized), Sharpe ratio (excess return per unit of risk given the risk-free rate), and maximum drawdown (largest peak-to-trough decline in the series).
Example use cases
Portfolio performance review for advisor
“Here are the quarterly NAV values for my client's portfolio over 3 years: [10000, 10450, 10800, 10300, 11200, 11900, 11400, 12600, 13100, 12700, 13800, 14500]. Can you compute the CAGR, total return, annualized volatility, and max drawdown?”
Sharpe ratio check for ETF comparison
“I want to compare two ETFs on risk-adjusted return. For the first one, here's the monthly price series: [50, 52, 51, 54, 57, 55, 59, 61, 60, 63, 66, 68]. Calculate the Sharpe ratio using a 5% risk-free rate and also give me the CAGR and max drawdown.”
Quick CAGR from start and end values
“My investment grew from $25,000 to $41,500 over 6 years — what's the CAGR and total return on that?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/return-cagr-drawdownWhen to prefer
Choose this endpoint when you need a comprehensive set of quantitative investment performance and risk metrics — especially CAGR, Sharpe ratio, and maximum drawdown — computed in a single call from a price or value series. Prefer it over building calculations manually or calling separate analytics APIs when you need a fast, cheap ($0.003), self-contained computation that covers both return and risk dimensions simultaneously.
Side effects
- Insufficient data points in series for meaningful volatility or drawdown computation
- Missing required inputs (no series provided and no start/end/years combination)
- Risk-free rate not provided when Sharpe ratio is requested
- Non-numeric values in the series causing parsing errors
- Zero or negative start value causing division errors in return calculations
- Series with fewer than 2 data points returning an error
