Information Ratio Calculator (IR Portfolio Performance

Portfolio Performance & Information Ratio Analysis

The Information Ratio (IR) is a key risk-adjusted performance metric used by institutional consultants and pension funds to evaluate active portfolio managers.

Core Financial Formulas

• Active Return (Alpha): Active Return (%) = Portfolio Return (%) - Benchmark Return (%)

• Tracking Error (TE): Annualized Standard Deviation of (Portfolio Return - Benchmark Return)

• Information Ratio: IR = Active Return (%) ÷ Tracking Error (%)

Interpreting Information Ratio Benchmarks

• IR < 0.00: Underperforming the benchmark index

• 0.00 to 0.49: Weak to modest active management skill

• 0.50 to 0.74: Good active management skill (Top 25% of managers)

• 0.75 to 0.99: Very good active manager consistency

• IR ≥ 1.00: Exceptional top-tier performance (Top 5% of global asset managers)

Strategic Role in Asset Allocation

Institutional portfolio allocators use the Information Ratio to determine fee structures, allocate active risk budgets, and decide whether to award mandates to active mutual fund and hedge fund managers.

How to Use This Calculator

Enter your Portfolio Annual Total Return (e.g. e.g. 14.5 in %), Benchmark Index Annual Return (e.g. e.g. 10.0 in %), and Tracking Error (Active Return Volatility) (e.g. e.g. 4.0 in %). Results update instantly as you type — adjust any value to compare scenarios.

The Formula

Worked Example

An equity fund generates a 14.50% annual return while its S&P 500 benchmark returns 10.00%, incurring a 4.00% tracking error: Active return is 4.50%, resulting in an IR of 1.125 (top 5% institutional manager performance).

Understanding Your Result

Percentages are relative values — context determines what is "good" or "bad." A 50% discount is significant; a 50% failure rate is alarming. Percentage change and percentage points are different: moving from 4% to 5% is a 1 percentage point increase, but a 25% relative increase. When comparing percentages across different base values, always check whether absolute differences are meaningful — a 10% improvement on a large base creates more absolute value than 10% on a small base.
