Information Ratio Calculator
Evaluate active investment portfolio performance, tracking error, and risk-adjusted alpha generation.
What is the Information Ratio Calculator?
The ToolboxDock Information Ratio Calculator is a free, 100% browser-based financial utility that calculates money metrics directly in client-side RAM with zero server transfers. It provides instant mathematical modeling for loans, investments, taxes, and amortization schedules while ensuring complete confidentiality of your sensitive financial data.
The Information Ratio (IR) Calculator evaluates fund manager skill and active portfolio consistency by dividing active excess returns by tracking error volatility relative to a benchmark index.
Financial Calculation Inputs
- Supported Inputs: Principal balances, interest rates, compounding schedules, and tenures.
- Precision Model: High-precision IEEE-754 floating-point arithmetic with decimal rounding.
- Data Privacy: Zero cloud logs. Figures are calculated locally in your browser memory.
Output & Schedule Breakdown
- Visual Analytics: Month-by-month schedules, dynamic charts, and cash flow summaries.
- Currency Support: Multi-currency symbol formatting (USD, EUR, GBP, INR, JPY, CAD, AUD).
- Access Guarantee: 100% unlocked with zero limits, subscriptions, or forced account creation.
How to Use the Information Ratio Calculator
Follow these 3 simple steps for instant, accurate calculations.
1. Input Portfolio & Benchmark Returns
Enter annualized total portfolio return and benchmark index return over the same evaluation timeframe.
2. Specify Annualized Tracking Error (TE)
Enter the annualized standard deviation of excess returns (tracking error volatility) relative to the benchmark.
3. Evaluate Manager Skill & Consistency
Analyze the resulting Information Ratio (IR), active excess return, and benchmark performance tier.

Information Ratio Formula
Measures portfolio manager skill by dividing excess active return by tracking error volatility, quantifying excess return generated per unit of active risk taken relative to a benchmark.
Core Information Ratio Calculator Inputs & Terminology
A financial metric that measures the risk-adjusted active alpha generated by a portfolio manager per unit of active tracking risk taken.
The difference between portfolio total return and benchmark index return (R_p - R_b).
The annualized standard deviation of the difference between portfolio returns and benchmark returns.
The degree of deviation from the benchmark index taken in pursuit of excess investment returns.
