Approximate real rate of interest vs exact real rate Rating: 7,7/10 519 reviews

The real rate of interest refers to the rate of return on an investment after adjusting for inflation. It is a measure of the opportunity cost of capital and represents the true cost of borrowing or lending money. The real rate of interest is an important concept for individuals, businesses, and governments, as it helps them make informed decisions about borrowing, lending, and investing.

There are two main ways to calculate the real rate of interest: the approximate real rate and the exact real rate. The approximate real rate is a simplified method that involves subtracting the current inflation rate from the nominal interest rate. For example, if the nominal interest rate is 4% and the current inflation rate is 2%, the approximate real rate of interest would be 2%.

The approximate real rate of interest is a useful tool for quickly estimating the real rate of return on an investment, but it has some limitations. It assumes that the inflation rate remains constant over the life of the investment, which may not always be the case. Inflation can vary significantly over time and can impact the real rate of return in different ways.

The exact real rate of interest, on the other hand, takes into account the expected future inflation rate, as well as the term of the investment. It is calculated using the Fisher equation, which states that the nominal interest rate equals the real interest rate plus the expected inflation rate. The exact real rate of interest provides a more accurate estimate of the real rate of return on an investment, as it takes into account the expected future inflation rate.

In conclusion, the real rate of interest is an important concept for understanding the true cost of borrowing or lending money. The approximate real rate of interest is a useful tool for quickly estimating the real rate of return on an investment, but it has limitations. The exact real rate of interest takes into account the expected future inflation rate and provides a more accurate estimate of the real rate of return.

## Getting Real about Interest Rates

Think back to our bucket example. Do not round intermediate calculations. The latter has offset the large borrowing demands by the US Federal Government, which might otherwise have put more upward pressure on real interest rates. Lenders, on the other hand, are the losers in this case and are not satisfied with the lower real rate. 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. However, during much of that time, inflation rates were also very highâ€”even higher than nominal interest ratesâ€”so real interest rates were negative. When the inflation rate goes up, it indicates that the prices of many goods and services are going upâ€”your dollars will then buy less than they did before.

## Real Interest Rate Formula

Based on these four years, what range of returns would you expect to see 99 percent of the time? For example, if the rate of return for bonds you hold is 6% and the inflation rate is 3%, then the real rate of return will be 3%, not 6%. Thus if a loan is made at 15% with an inflation rate of 5% and 10% in risks associated with default or problems repaying, then the "risk adjusted" rate of return on the investment is 0%. Notice that the approximation here is a bit rough; since 1. 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.
