real interest rate

The nominal current interest rate minus the rate of inflation. For example, an investor holding a 10% certificate of deposit during a period of 6% annual inflation would be earning a real interest rate of 4%. The real interest rate is a more valid measure of the desirability of an investment than the nominal rate is.

Real Interest Rate

An interest rate after accounting for inflation. A nominal interest rate shows by how much an investment or account has grown in raw dollar amounts and may not be an accurate accounting of how well or poorly an investment is performing. The real interest rate adjusts for how much buying power has been affected and, therefore, provides a more accurate view. For example, if one has bond with a 5% coupon, and the inflation rate is 3%, the real interest rate is only 2%. The real interest rate does not take compounding into account.

Real interest rate. Your real interest rate is the interest rate you earn on an investment minus the rate of inflation.

For example, if you're earning 6.25% on a bond, and the inflation rate is 2%, your real rate is 4.25%. That's enough higher than inflation to maintain your buying power and have some in reserve, which you could use to build your investment base.

But if the inflation rate were 5%, your real rate would be only 1.25%.
