Understanding What is Risk Free Rate of Return
The primary objective before selecting an investment is to achieve a favourable return while minimising the associated risks. Although some investments may have lower risks than others, it's impossible for a financial instrument to be entirely risk-free.
The risk free rate of return is theoretically influenced by three fundamental factors:
InflationAn economy's overall prices for goods and services rising noticeably and continuously over time is referred to as inflation. It stands for the inflation rate when investing in a risk-free environment.
Rental RateThe rental rate signifies the actual realised return on the investment. In this case, it relates to the regular return from the risk-free investment that investors receive without any defaults.
Investment RiskThis factor symbolises the inherent risk associated with every investment tool, which can lead to a decrease in its value. In this scenario, the investment risk is considered to be zero, indicating that investors cannot incur losses.
Calculation of Risk Free Return
Traditionally, computing the risk-free rate involves considering the investment duration in a risk-free instrument. However, the widely respected Capital Asset Pricing Model (CAPM) offers a sophisticated approach to assess risk-free returns. According to CAPM, the risk free rate of return is derived by matching security returns with the sum of the risk premium and the risk-free return.
The CAPM formula is: Ra = Rf + [Ba x (Rm - Rf)]In this equation:
- Ra signifies the return on a specific security.
- Ba represents the security's beta, indicating its volatility or systematic risk.
- Rf denotes the risk-free rate.
The risk premium is determined by the difference between market return (Rm) and risk-free return (Rf) as outlined in the formula. Essentially, beta in the CAPM model elucidates the connection between expected asset returns and their corresponding systematic risk.
Example of Risk Free Return
An example of a risk-free return is challenging to find due to the inherent risks associated with most financial instruments. If investors want a safe way to make profit, they can consider Treasury Bills. These are like special papers sold by the government. They don't promise a fixed payment, but when you buy them for less than their worth, the government will pay you back the full amount when they mature, which is usually within a year. Given that the government backs it, investing in this way is safe, so there's a high chance you'll get decent returns on your investment. For example, if you buy a Treasury Bill worth Rs 100 for Rs 98, you'll earn profit based on the Rs 2 difference.
What does the risk free rate of returns signify for Investors?
Once you understand the basic idea of the risk-free rate of return, it's natural to wonder how it affects investors like you. This concern is totally understandable. So, let's talk about what the risk-free rate of return means for investors. It refers to investments that are considered completely safe, with no risk involved. Any other investment that has even a little risk must offer higher returns to attract investors. In simple words, the risk-free rate of return is the lowest expected rate of return from investments in the market.
This rate is like a standard for figuring out other rates, like the cost of equity. The cost of equity is calculated by adding extra money (called a risk premium) to the current risk free rate in the market. This accounts for the extra risk of different investment options. Similarly, the risk-free interest rate is used to figure out the cost of debt. The concept of risk-free rate influences how companies decide on their investment projects. When companies evaluate potential projects, they compare the expected returns from these projects with the risk-free rate.
Conclusion
A risk free rate is like a pretend number that shows how much profit you can make without taking any risks. It's an ideal concept, but in real life, there's no completely safe investment. So, before investing, people need to look at different options and see how risky they are. Figuring out how long you want to invest for is also really important when you're trying to find a safer investment.
The risk-free rate of return is a crucial factor to take into account as a benchmark for your investment selections, irrespective of the length of your investment period. It assists you in determining if the minimal rates of return on your investments are being earned. It's a sign that the additional risk you took paid off well if the actual rate of return exceeds the risk free rate of return.

FAQs
Risk free rate is the ideal return on investment with no risk. Investors only take risks if the potential return is higher than the risk-free rate. In reality, no investment is entirely risk-free, they all have some level of risk.
How to calculate risk-free rate with example? ›
The risk-free rate represents the interest an investor would expect from an absolutely risk-free investment over a specified period of time. The so-called "real" risk-free rate can be calculated by subtracting the current inflation rate from the yield of the Treasury bond matching your investment duration.
What does risk-free rate of return mean? ›
The risk-free rate of return is the interest rate an investor can expect to earn on an investment that carries zero risk. In practice, the risk-free rate is commonly considered to be equal to the interest paid on a 10-year highly rated government Treasury note, generally the safest investment an investor can make.
What is an example of risk-free return? ›
Example of Risk-Free Return
Treasury bills are issued by the government and mature within one year. These bills do not offer a fixed interest payment but offer returns at maturity by allowing investors to buy the bills at a lesser rate than the face value.
What is the risk-free rate of securities? ›
The Risk Free Rate (rf) is the theoretical rate of return received on zero-risk assets, which serves as the minimum return required on riskier investments. The risk-free rate should reflect the yield to maturity (YTM) on default-free government bonds of equivalent maturity as the duration of the projected cash flows.
How to calculate expected return with risk-free rate? ›
Expected return = Risk Free Rate + [Beta x Market Return Premium]
How do you calculate risk examples? ›
Risk is calculated by dividing the net profit that you estimate would result from the decision by the maximum price that could occur if the risk doesn't pan out. Compare the resulting ratio against your risk tolerance and threshold to inform your decision.
Is a higher or lower risk-free rate better? ›
The risk-free rate is also important for calculating the Sharpe ratio. This analytical tool is used to evaluate the risk-adjusted returns on a single security or an entire investment portfolio. For both CAPM and the Sharpe ratio, the higher the ratio, the better the investment.
Can you have a negative risk-free rate of return? ›
The correct interpretation is that the risk-free rate could be either positive or negative and in practice the sign of the expected risk-free rate is an institutional convention – this is analogous to the argument that Tobin makes on page 17 of his book Money, Credit and Capital.
What is an example of a risk-free asset? ›
A risk-free asset is an investment with a guaranteed future value and virtually no potential for loss. Debt issued by the U.S. government (bonds, notes and Treasurys) is one of the most well-known risk-free assets.
The risk-reward ratio is calculated by dividing the potential reward or return of an investment by the amount of risk undertaken to achieve that return. A higher ratio indicates that the potential reward is greater relative to the risk involved.
What type of investment gives you a risk-free rate of return? ›
U.S. Treasuries are seen as a good example of a risk-free investment since the government cannot default on its debt. As such, the interest rate on a three-month U.S. Treasury bill is often used as a stand-in for the short-term risk-free rate, since it has almost no risk of default.
What is an example of a risk return? ›
For example, if you buy stock for $10,000 and sell it for $12,500, your return is a $2,500 gain. Or, if you buy stock for $10,000 and sell it for $9,500, your return is a $500 loss. Of course, you don't have to sell to figure return on the investments in your portfolio.
What is an example of a risk-free rate? ›
Example 1 – US Treasury Bills
These are the safest investment as they are backed by the US government. T bills carry a zero default risk as they are fully guaranteed and credit by the US government and the Treasury Department.
Why do we need a risk-free rate? ›
The risk-free rate signals an investment that has no risk; the investor will not lose money. The rate is the main component of many famous theories, such as the capital asset pricing model (CAPM), modern portfolio theory (MPT), and the Black-Scholes model.
What is the meaning of risk-free? ›
Definitions of risk-free. adjective. thought to be devoid of risk. synonyms: riskless, unhazardous safe. free from danger or the risk of harm.
How do you calculate the risk rate? ›
Risk ratios. When risks are computed in a study, the risk ratio is the measure that compares the Riskexposed to the Riskunexposed . The risk ratio is defined as the risk in the exposed cohort (the index group) divided by the risk in the unexposed cohort (the reference group).
How to calculate risk-free rate for Sharpe ratio? ›
To calculate the Sharpe ratio, investors first subtract the risk-free rate from the portfolio's rate of return, often using U.S. Treasury bond yields as a proxy for the risk-free rate of return. Then, they divide the result by the standard deviation of the portfolio's excess return.
How do you calculate beta risk-free rate? ›
Subtract the risk-free rate from the market (or index) rate of return. If the market or index rate of return is 8% and the risk-free rate is again 2%, the difference would be 6%. Divide the first difference above by the second difference above. This fraction is the beta figure, typically expressed as a decimal value.
Is risk-free rate the same as discount rate? ›
While investing in standard assets, like treasury bonds, the risk-free rate of return—generally considered the interest rate on the three-month Treasury bill—is often used as the discount rate.
