Imagine a world where you could invest your money and be 100% sure that you’ll get it back, along with some extra. Well, that’s what the term “risk-free rate of return” is all about. It’s the idea of investing your money where the risk is so low that it’s almost like storing your cash under a financial mattress. But does such a rate really exist?

Let’s dive into it.

**What is the risk-free rate of return?**

A risk-free rate of return is the hypothetical interest rate you’d earn on an investment that has absolutely zero risk. This theoretical rate serves as a foundational benchmark in the financial world, helping investors evaluate the attractiveness of various opportunities.

Imagine you have two investment options—one is a high-flying tech startup, while the other is a government bond.

The risk-free rate of return helps you figure out a big question – Is the chance to make more money from a risky startup worth taking a chance, especially when you could make some money for sure from a safer government bond?

In essence, the risk-free rate of return sets the bar for what an investor should at least aim to achieve with any investment.

**The myth and reality of risk-free**

There’s a reason we call the risk-free rate “theoretical.” In practice, no investment is entirely devoid of risk. Even the safest bet, like government bonds or Treasury bills, carries some minimal risks.

One of the most pervasive is inflation risk. Suppose you invest in a 10-year government bond with a 2% annual return. If inflation rates rise to 3%, the buying power of your returns would actually decrease over time despite the investment itself being “safe.”

Therefore, when financial experts talk about a “risk-free” rate, they are generally referring to investments that are as close as you can get to a guarantee in the complex and ever-changing landscape of financial markets.

**What does the risk-free rate of return indicate?**

Hearing the term “risk-free rate of return” might make you think you’ve found the golden ticket to investments. It sounds like you can earn money without losing any, right? Well, let’s dig a bit deeper to understand what’s actually involved.

**Core components of risk-free rate of return**

The idea behind the risk-free rate of return is built on three main pillars:

**Inflation**

Holding onto money doesn’t mean its worth remains the same over time. Prices for things like food and housing usually go up, and this is called inflation. When considering a risk-free investment, it’s vital to think about how much prices will rise while you have your money invested.

**Rental rate**

Though the rental rate might sound like it’s related to renting a house, here it means something different. The rental rate is the real money you earn from your investment. For instance, if you invest ₹100 and get back ₹105, that extra ₹5 is your rental rate. When an investment is described as “risk-free,” this means you are guaranteed to get this return without any hiccups.

**Investment risk**

Everywhere you put your money carries some level of risk. However, in a risk-free rate of return, this risk is considered to be nonexistent. In theory, you’re not taking any risks that would result in a loss of the money you’ve invested.

**Calculation of risk-free return**

A common method to calculate the risk-free return is using a formula that finance folks call the Capital Asset Pricing Model or simply CAPM. This formula can help you understand what kind of return you should aim for, taking into account the risk level of your investment compared to the market.

**Breaking down the formula**

*Here’s what the formula looks like:*

Let’s decode what each component means:

Ra is the return you're hoping to get from the investment. β, often called beta, tells you how the investment's value is likely to change compared to the whole market. Rf is the risk-free rate, which is the number we are keen on. Rm is what you'd expect the market to return. The part that says (Rm - Rf) is often called the risk premium. It represents the extra return you'd want to make for taking on a higher risk than you would with a risk-free investment.

**What is beta?**

Beta is a sort of yardstick to measure how an investment behaves compared to the market. If beta is 1, the investment and the market are in sync. A beta higher than 1 means the investment is more likely to experience ups and downs, and a beta lower than 1 indicates less volatility.

**Example of risk-free return**

It’s almost impossible to find an investment that has zero risk. However, some investments come very close to being risk-free, and treasury bills are an excellent example.

To illustrate, let’s consider you’re an investor in India. You buy a treasury bill with a face value of Rs 100 at an issue price of Rs 98. When the bill matures, you will get back Rs 100. The risk-free rate of return in this example can be calculated based on the difference between the face value (Rs 100) and the issue price (Rs 98).

So, in this case, your almost risk-free return would be Rs 2, which might not sound like much, but remember, the risk involved is minuscule.

**Risk-free investments**

The term “risk-free” might be a bit of an exaggeration, but there are investments that are considered extremely safe. These are usually government-backed securities called government securities in India. These investments are considered safe because they are backed by the full faith and credit of the government.

**Conclusion**

The term “risk-free rate of return” might sound like a guarantee, but remember, no investment is entirely without risk. However, it’s one of the safest options you have for investment.

It serves as a yardstick against which you can measure the returns of other, riskier investments.]

When you’re looking to invest, consider the risk-free rate as your starting point. Any investment offering higher returns should also clarify the extra risks involved.

Now you should have a clear understanding of what the risk-free rate of return is, why it’s important, and how to calculate it.
