Sharpe Ratio Calculator
Risk-adjusted return per unit of volatility — the universal fund comparison number with interpretation bands.
Formula
Sharpe lets a 14% return at 16% vol beat an 18% return at 30% vol — risk-adjusted is the only fair race. Caveats: it punishes upside volatility too (see Sortino) and assumes normal returns, understating strategies with crash tails (option selling looks great until it doesn't).
