Risk-adjusted return: what it is, how to calculate it & examples

What is risk-adjusted return?

In simple terms, risk-adjusted return measures how efficiently an investment turned risk into return. If two portfolios both returned 10%, the steadier one generally has the better risk-adjusted return. CFA Institute’s case study puts it plainly: the higher the Sharpe ratio, the better the risk-adjusted return.

That matters because raw return can be misleading. A portfolio that jumps up 20% and down 15% may look great in a screenshot and still be miserable to hold in real life. That is where ideas like volatility, diversification, capital preservation, and risk tolerance start to matter more than headline performance. The SEC also notes that diversification is meant to reduce risk, even though it cannot guarantee against losses.

Why risk-adjusted return matters

Risk-adjusted return is useful any time you are comparing investments that do not take the same amount of risk. That could mean two ETFs, two hedge funds, two managers, or two alternative investments with very different volatility and liquidity profiles. It is also useful for comparing strategies: did the manager actually add value, or did they just swing harder? Morningstar’s methodology for fund ratings is based on comparing funds using risk-adjusted historical returns rather than raw returns alone.

This is also where the topic connects naturally to the rest of the glossary. If you are learning about volatility, diversification, risk tolerance, capital preservation, liquidity risk, internal rate of return (IRR), or multiple on invested capital (MOIC), you are really learning different pieces of the same puzzle: why “highest return” and “best investment” are not always the same thing.

How to calculate risk-adjusted return

There is no single formula that works for every situation. The right method depends on what kind of risk you care about: total volatility, downside risk, benchmark-relative risk, or market risk.

Sharpe ratio

The Sharpe ratio is the most common way to calculate risk-adjusted return. CFA Institute describes it as the mean excess portfolio return over a risk-free rate divided by the portfolio’s standard deviation. Put differently: how much extra return did you earn for each unit of total volatility you accepted? Higher is better.

Sortino ratio

The Sortino ratio tweaks that idea by focusing only on downside risk. CFA Institute explains that it replaces the risk-free rate with a minimum acceptable return and replaces standard deviation with downside deviation. That makes it useful when you do not want months with strong upside to count as “risk.”

Treynor ratio

The Treynor ratio uses beta instead of standard deviation. CFA Institute describes it as the excess return per unit of market risk, which makes it more useful when comparing already diversified portfolios and wanting to isolate sensitivity to market movements.

Information ratio

The information ratio shifts the question from “return versus cash” to “return versus benchmark.” CFA Institute defines it as excess return divided by tracking error. This is especially useful when you are comparing an active manager, hedge fund, or direct investment strategy against an index or policy benchmark.

A practical rule: compare like with like. Use the same time period, a sensible benchmark, and investments that actually belong in the same conversation. As referred to above, Morningstar’s ratings compare funds within categories.

Risk-adjusted return examples

Here is the simplest way to see why this matters.

Example 1: lower raw return, better Sharpe ratio

Assume the risk-free rate is 2%.

Portfolio A had the higher raw return. Portfolio B had the better risk-adjusted return because it produced more excess return per unit of volatility. That is the core intuition behind risk-adjusted analysis. A higher Sharpe ratio indicates a more efficient risk-adjusted return.

Example 2: higher outperformance, weaker information ratio

Now compare two managers against an 8% benchmark.

Manager Y beat the benchmark by more in raw terms. But Manager X did it more efficiently relative to benchmark risk, so X has the stronger information ratio. This is why sophisticated investors often care as much about consistency as they do about upside.

What risk-adjusted return does not tell you

Risk-adjusted return is helpful, but it is not magic. It depends on the time period, the benchmark, and the risk measure you choose. A Sortino ratio can tell a different story than a Sharpe ratio. A Treynor ratio can look attractive even if a portfolio carries meaningful idiosyncratic risk outside the benchmark. That is why these metrics work best as comparison tools, not as stand-alone verdicts.

It is also important to be careful in private markets. Especially since the Sharpe ratio is rarely used to evaluate private equity because illiquidity can bias the measured standard deviation downward, making an investment look smoother than it really is. In those settings, investors often pair return metrics with since-inception IRR and other private-market measures. That is especially relevant for pre-IPO, direct investment, and other alternative investments where liquidity can be limited, and the path to exit may depend on a secondary market or an IPO. The SEC defines liquidity risk as the risk that investors may not be able to find a market for their securities when they want to buy or sell.

So, in practice, risk-adjusted return should sit alongside other questions: How liquid is this investment? How concentrated is the position? Does the benchmark make sense? Does this fit my risk tolerance? Am I optimizing for growth, capital preservation, or both?

Factors that may influence risk-adjusted return

You may not improve risk-adjusted return by chasing higher returns alone. Rather than focusing solely on return, some investors consider whether the quality and composition of the risk they are taking is appropriate for their goals.

One approach some investors consider is diversification. The SEC says diversification means spreading money among different investments to reduce risk, even though it cannot guarantee you will avoid losses. Good diversification can reduce return fluctuations without requiring you to abandon return goals altogether.

Second, consider your risk tolerance. The SEC defines risk tolerance as your ability and willingness to lose some or all of your original investment in exchange for potentially higher returns. Some investors find it useful to consider whether a portfolio's risk level aligns with their individual risk tolerance. 

Third, some investors periodically review and rebalance their portfolios to manage drift in risk exposure over time. The SEC notes that rebalancing can bring a portfolio back to its intended risk level over time. That matters because a portfolio can quietly drift into taking more risk than you planned after a strong run.

Risk-adjusted return vs. return, IRR, and MOIC

Plain returns answers, “How much did this investment make?” Risk-adjusted return answers, “How well was I compensated for the risk I took?” That is a different question, and a better one whenever two opportunities do not carry the same volatility, downside risk, or liquidity profile.

In private markets, this is why raw upside metrics should be paired with context. IRR can help you understand timing-sensitive returns. MOIC can help you understand how many times your money came back. Risk-adjusted return adds another lens: whether the ride, uncertainty, and liquidity trade-offs were actually worth it. That combination can provide a different perspective than any single number in isolation.

Final thoughts

If you remember one thing, make it this: risk-adjusted return is about efficiency, not just excitement. The goal is not to find the loudest return number. It is to find the return that made sense for the risk, volatility, liquidity, and uncertainty involved.

That is why risk-adjusted return matters across public stocks, hedge funds, diversified portfolios, and alternative investments alike. When considered alongside factors such as diversification, liquidity, volatility, and individual risk tolerance, risk-adjusted return metrics may provide a more complete picture of an investment's characteristics than raw return figures alone.
