From an investor’s perspective, it is important to understand the concept of real interest rate because it captures the real growth of the wealth after adjusting the inflation rate. One needs to be cognizant of the fact that inflation erodes the value of every stream of cash flows, either mainstream like salary or passive like return on investment. As such, it is essential that we consider the impact of inflation while making a decision about any investment from which we expect a stream of cash flows in the future.
What Is the Difference Between Nominal and Real Interest Rates?
So lenders that want to earn 6% interest when the inflation rate is 2% (and is expected to rise) may factor into their nominal rates a higher level of inflation. According to the Fisher Effect, real interest rates drop as inflation rises, until nominal rates also rise. 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. As a simple example, let’s say you’re considering purchasing a product that costs $103, but you only have $100. 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.

If inflation pushes higher while nominal interest rates remain unchanged, it results in lower real interest rates. Some bank accounts pay a nominal interest rate of at least 5% per year, which would be higher than the aforementioned rate of inflation and in this case provide a positive real interest rate. Online banks, in particular, might offer higher interest rates than their more traditional alternatives.
Formula – How to calculate real interest rate
Dealing with hyperinflation, the nation had a nominal interest rate close to 80% when this analysis was done. Mexico also had a high expected real interest rate of 6.05%, based off a nominal interest rate of 11%. Chile had a real interest rate of 4.92%, as well as a nominal interest rate of 11.25%. Prior to discussing how to calculate real interest rate, let’s define what interest and interest rate is. Interest is the monetary charge for borrowing money while an interest rate is a percentage that you are charged for borrowing money. If an investor expected a 7% interest rate with inflation at 2%, the real interest rate would be 5% (7% minus 2%).
- Both of these figures are below headline inflation, which recorded a year-over-year increase of 3.5% in March.
- You can benefit from looking beyond nominal interest rates to find the real interest rate when making investment and borrowing decisions.
- Let us take the example of David who has recently invested a sum of $20,000 in a long term deposit fund.

It is the stated interest rate paid or earned to the lender or by investor. So, if as a borrower, you get a loan of $100 at a rate of 6%, you can expect to pay $6 in interest. The real interest rate is so named, because unlike the nominal rate, it factors inflation into the equation, to give investors a more accurate measure of their buying power, after they redeem their positions. If an annually https://www.kelleysbookkeeping.com/what-is-the-objective-of-financial-statements/ compounding bond lists a 6% nominal yield and the inflation rate is 4%, then the real rate of interest is actually only 2%. The nominal interest rate is the stated interest rate of a bond or loan, which signifies the actual monetary price borrowers pay lenders to use their money. If the nominal rate on a loan is 5%, borrowers can expect to pay $5 of interest for every $100 loaned to them.
So, if you put savings in an account with a negative real interest rate, those dollars will buy you less over time. Nominal interest rates do not account for inflation while real interest rates do. For example, in the United States the federal funds rate, the interest rate set by the Federal Reserve, can form the basis for the nominal interest rate being offered. The real interest, however, would be the nominal interest rate minus the inflation rate, usually measured by the CPI (Consumer price index). That’s because nominal rates are determined by taking real interest rates and adding a projected rate of inflation to them. Of course, higher real interest rates can also improve the returns people may earn on their investments.
The real interest rate gives investors a better idea of the rate at which their purchasing power increases or decreases. 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. everything you need to know about big 4 accounting firms In case you don’t know the nominal interest rate applied to your loans, you can determine it with our nominal interest rate calculator.

Remember that nominal interest rates equal real interest rates plus the expected rate of inflation. As such, they must take it into account when they advertise their rates.
Once adjusted, it reflects the real cost of funds to a borrower and the real yield to a lender or to an investor. After rearranging the variables, we find that the real interest rate equals the nominal interest rate minus the expected rate of inflation. The term nominal can also refer to the advertised or stated interest rate on a loan, without taking into account any fees or compounding of interest. It’s important to understand that to obtain the real short-term federal funds rate, one would subtract the inflation rate from the nominal rate. For example, the personal consumption expenditure (PCE) rate, which is the rate that the Fed focuses on to gauge inflation, could be subtracted.
If inflation is high enough, the possibility of negative real interest rates leads shoppers to prefer buying goods today instead of waiting to make the purchase. This is commonly referred to as the time-preference theory of interest. Depending on the rate of inflation, the real interest rate can differ significantly from the nominal interest rate. If the initial interest rate on a bond was 15% and the projected rate of inflation was 2%.
The resulting elevated level of interest rates may have serious economic repercussions, as they tend to stall spending. You cannot determine the real interest rate without first understanding the nominal interest rate, which is simply the interest rate before you account for inflation.
