## How to Calculate the Real Interest Rate

Generally speaking, rising inflation may prompt the Fed to raise nominal short-term rates to try to reverse it. Inflation makes products and services more expensive and thereby reduces consumer purchasing power, or how much they can buy with the same amount of money as prices go up. Real rates are usually more used when analyzing investment decisions. When planning for long-term financial goals like retirement, real interest rates are more relevant as they incorporate eroding purchasing power. In addition, assessing international investments may call for real rates as different regions may be impacted by differing macroeconomic policies.

## What Is Nominal Interest Rate?

While that rate of borrowing may be fine for the homebuyer, it may not be profitable for the lender. A real interest rate is the interest rate that is added to the projected rate of inflation to provide the nominal interest rate. Put simply, this interest rate provides insight into the actual return received by a lender or investor after a rate of inflation is https://www.kelleysbookkeeping.com/ acknowledged. This type of rate is considered predictive when the true rate of inflation is unknown or expected. Nominal interest rates exist in contrast to real interest rates and effective interest rates. Real interest rates tend to be important to investors and lenders, while effective rates are significant for borrowers as well as investors and lenders.

## Statistics and Analysis Calculators

Nominal rates, on the other hand, are indicative of the current mood or conditions of the market, the state of the economy, and the total price of money. When the economy is healthy, nominal rates tend to be higher than in times of economic distress. The relationship between real and nominal interest rates can be expounded to other economic concepts. For example, economists may analyze the change in real vs. nominal prices of goods.

## How It Impacts Investors

Therefore, in this case, the real interest is calculated to be 3.85% using the first formula and 4% using the Fisher equation. One thing to keep in mind while using the Fisher formula for calculating the real interest rate, it will give you an approximate value, not an absolute one. So the real interest rate is 5 percent in year 2, 3.9 percent in get familiar with the cpa exam by practicing with our sample tests year 3, and a whopping 12.2 percent in year four. Finance is riddled with terms that can make the uninitiated scratch their heads. A nominal variable is one that doesn’t incorporate or consider the effects of inflation. Treasury Inflation Protected Securities (TIPS) allow investors to preserve their savings without losing value to inflation.

- Say the initial interest rate on a bond was 9.62% and the projected rate of inflation was 3.6%.
- While that rate of borrowing may be fine for the homebuyer, it may not be profitable for the lender.

Let’s try to calculate the real interest rate for “Country A” using the Fisher equation. First, let’s try to identify the value for nominal interest rate and inflation rate in this problem. The concept of the real interest rate is particularly helpful to perceive the real yield to the investor or the borrower and the real cost of the fund to the borrower. This concept is the brainchild of Irving Fisher, one of the great monetary economists of the 20th century.

The formula for the real interest rate is the nominal interest rate minus the inflation rate. To calculate the nominal rate, add the real interest rate and the inflation rate. To a lesser degree, the same can be said regarding inflation-tied bonds such as Series I bonds issues by the U.S. government. These bonds are tied to an average rate of inflation over a period of time.
