Measure active return relative to positive tracking error.
It makes the prices, cash flows, rates, time periods, weights, and model conventions explicit so you can inspect an entered scenario without hidden live-market assumptions.
Calculation structure
Follow the stated model and units
Information ratio = (portfolio return − benchmark return) ÷ tracking error.
Visual explanation

Read the estimate correctly
Use the result within its boundaries
A 9% portfolio return, 7% benchmark return, and 4% tracking error produce 0.5.
This is a visitor-entered arithmetic scenario, not live market data, a forecast, a suitability assessment, or an investment recommendation.

How to use this calculator
Enter the exposure, market, accounting, probability, rate, or risk assumptions named by the fields.
Use consistent currencies, periods, share units, and percentage conventions.
Interpret the output only within the displayed model and limitations.
Calculation method
Calculation method
Information ratio = (portfolio return − benchmark return) ÷ tracking error.
Fixed decimal scalar arithmetic remains exact until display. Square-root and compound projections are explicitly approximate and reject non-finite results.
Worked example
Worked example
A 9% portfolio return, 7% benchmark return, and 4% tracking error produce 0.5.
Information ratio = (portfolio return − benchmark return) ÷ tracking error.
Supported inputs
Precision and limits
Visible input limits
Fixed decimals accept 30 digits and 12 decimal places, with absolute values capped at 1e12 per input and general rates capped at 1000%. Formula-specific shares and probability limits are validated separately.
International scope
No currency, exchange, broker, live security data, accounting standard, tax jurisdiction, contract specification, or regulatory disclosure is selected automatically.
Decision boundary
Outputs are arithmetic scenarios, not forecasts, advice, suitability assessments, trading signals, fair-value opinions, risk guarantees, or recommendations.
Calculator-specific assumptions
This is a visitor-entered arithmetic scenario, not live market data, a forecast, a suitability assessment, or an investment recommendation.
