# Real Interest Rate: Definition, Formula, and Example

A nominal interest rate equals the real interest rate plus a projected rate of inflation. A real interest rate reflects the true cost of funds to the borrower and the real yield to the lender or to an investor. If the level of inflation is higher than the nominal interest rate, you will have what is referred to as a negative real interest rate. Negative real interest rates indicate that the principal will lose its purchasing power over time. So, if you put savings in an account with a negative real interest rate, those dollars will buy you less over time.

## Effect of Inflation on the Purchasing Power of Investment Gains

You decide to put that money into an account that pays simple interest of 3% over one year, so at the end of the year you’ll have $103. However, inflation is 5%, so at the end of the year, the product costs $105. With that price increase, you won’t have enough to buy the item because when you put your money into the aforementioned savings account, you only considered the nominal interest rate and not the real interest rate. “In contrast, if the real interest rate is negative, saving today to buy the same product later won’t be feasible, as your purchasing power will diminish.” It’s important that investors bear in mind current and expected inflation rates when they research where to put their money.

It suggests that the real interest rate—or the return received by lenders and borrowers—drops as inflation rises, until nominal interest rates rise in conjunction with inflation.

For example, nominal interest rates indicate what we’d be charged for a loan, but the real interest rate can help us decide whether or not the loan is too costly for our budgets.

- 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.
- Inflation rates are a major variable that impact real interest rates, as they have a significant influence on whether these interest rates are positive or negative.
- Low nominal rates encourage consumers to take on more debt and increase their spending.
- If the real interest rate is a positive value, the money you need to pay back is worth more in real terms as opposed to the amount you borrowed.
- CPI measures the change in an average price of a basket of selected goods and services over a specific period of time.

To calculate the interest on investments instead, use the Interest Calculator, or use the Compound Interest Calculator to understand the difference between different interest rates. Let us take the example of David who has recently invested a sum of $20,000 in a long term deposit fund. The tenure of the fund is 10 years and the annualized nominal interest rate offered is 4%. If the inflation rate during the period is expected to be 2%, then calculate the real interest rate as per the full formula and the approximate formula.

Federal Reserve dropped the federal funds rate to a range of 0% to 0.25%. The rate remained in this range between December 2008 and December 2015. The Fisher equation has proven to be useful within the area of monetary policy.

A real interest rate is an interest rate that has been adjusted to remove the effects of inflation.

Borrowers who are eager to enjoy the present use of funds show a stronger time preference for current goods over future goods.

The effective annual interest rate can also be used to compare products in an apples-to-apples way. Typically, that will result in an actual lower fed funds rate that’s more stimulative for the economy than is the published, nominal rate usually referred to by media and the government. It is also commonly employed within the disciplines of economics and finance; for example, it may be used to forecast real and nominal interest rate patterns or compute the returns on investment. In cases where inflation is positive, the real interest rate will be lower than the advertised nominal interest rate. Similarly, a lender who strongly prefers to put off consumption to the future shows a lower time preference and will be willing to loan funds at a lower rate. Adjusting for inflation can help reveal the rate of time preference among market participants.

Using this simple formula, you can calculate the real interest rate for years two through four. The real interest rate is the interest rate adjusted for the inflation rate. The expected rate https://www.online-accounting.net/adjusting-entries/ of inflation is reported to Congress by the Federal Reserve (Fed), among others.
