Treynor Ratio Calculator

Measure the risk-adjusted return of a portfolio using beta. This page also keeps the formula, examples, FAQs, and references close by so you can check the result with confidence.

What This Treynor Ratio Calculator Helps You Do

The Treynor ratio subtracts the risk-free rate from the portfolio return and divides by beta. Review the formula and examples below if you want to see how the result is derived.

This page is meant to give you a fast answer, but it also helps you double-check the math before you make a decision. Start with the inputs that you already know, run the calculation, and then compare the output with the formula, examples, and FAQs below so you can see whether the answer fits the situation you are modeling.

If the result looks off, the usual causes are a unit mismatch, a missing decimal, the wrong scenario, or a value that needs to be entered as a rate instead of a total. The notes on this page are designed to make those checks easy without forcing you to leave the calculator and search for context elsewhere.

  • Use the calculator first for a quick estimate.
  • Use the formula to understand how the result is built.
  • Use the examples to compare common use cases.
  • Use the references when the answer depends on a standard or assumption.

Common Checks

A quick result is useful, but the best result is one that still makes sense when you look at it a second time. If you are comparing scenarios, try changing one input at a time so you can see which variable has the biggest impact on the final answer. That makes it much easier to spot whether the calculation matches your expectations.

It also helps to keep the context of the problem in mind. A calculator can tell you the math, but you still need to decide whether the input represents a total, a rate, an average, or a category-specific assumption. When in doubt, start with a simple example from the page and scale up from there.

  • Check that every unit matches the rest of the problem.
  • Keep rates, totals, and averages separate.
  • Adjust one variable at a time when testing scenarios.
  • Use the smallest realistic input first, then scale upward.

Scenario Planning

This calculator is especially useful when you want a quick answer before you commit time, money, or effort. Try one baseline input set, then change a single number and compare the result so you can see how sensitive the answer is to that variable.

That makes the page useful for more than just arithmetic. It becomes a small decision aid that helps you compare options, test assumptions, and explain the final number with confidence when you need to share it with someone else.

Quick Answer: The Treynor ratio subtracts the risk-free rate from the portfolio return and divides by beta. Review the formula and examples below if you want to see how the result is derived.

How to Calculate Treynor Ratio Calculator

  1. Enter portfolio return: Use the return you want to evaluate.
  2. Enter the risk-free rate and beta: Beta should be the portfolio's market sensitivity.
  3. Read the ratio: A higher Treynor ratio indicates better risk-adjusted performance.

Treynor Ratio Calculator Formula

Treynor ratio = (Portfolio return - Risk-free rate) / Beta.
Variable Meaning Unit
Portfolio return Expected or realized portfolio return %
Risk-free rate Return on a risk-free asset %
Beta Systematic risk relative to the market

Worked Examples

USA - Balanced portfolio
  • Portfolio return: 12%
  • Risk-free rate: 3%
  • Beta: 1.2

Result: 7.5%

The portfolio earned 7.5 percentage points of excess return per unit of beta.

USA - Stronger performance
  • Portfolio return: 15%
  • Risk-free rate: 3%
  • Beta: 1.0

Result: 12%

The portfolio produced 12 percentage points of excess return per unit of beta.

USA - Solve for beta
  • Portfolio return: 10%
  • Risk-free rate: 2%
  • Treynor ratio: 4%

Result: 2.0

A beta of 2 would match the target Treynor ratio.

How to Interpret Your Results

Range Meaning Action
Negative Underperforming risk-adjusted return Review the portfolio strategy.
Near zero Little excess return after adjusting for beta Compare against benchmarks.
Positive and rising Improving risk-adjusted return Check whether gains are sustainable.

Frequently Asked Questions

Beta measures a portfolio's sensitivity to market movements.

Yes. The calculator treats returns and the risk-free rate as percentage values.

Generally yes, because it means more excess return for each unit of market risk.
Planning note: This is a simplified investing metric and not portfolio advice.
