## Effective rate

A measure of the time value of money that fully reflects the effects of compounding.

## Effective Interest Rate

The interest rate on a debt or debt security that takes into account the effects of compounding. For example, if one has a fixed-income investment such as certificate of deposit that pays 3% in interest each month, the effective interest rate is more than 3% because compounding the interest results in a (slightly) greater principal each month on which the interest rate is calculated. In this example, the effective interest rate is calculated thus:

Effective interest rate = (1 + .03/12)^12 - 1 = .0304 = 3.04%, where .03 is the simple interest rate and 12 is the number of times in a year interest is compounded. It is also known as the annual effective rate or the annual equivalent rate. See also: Stated annual interest rate, annual percentage yield.

## Effective Rate

The interest rate adjusted for intra-year compounding.

Because interest on a mortgage is calculated monthly, a 6% mortgage actually has a rate of .5% per month. If there were no principal repayments the first year, \$100 invested in a 6% mortgage would actually earn \$6.17 of interest during the year because of reinvestment of monthly interest. The “effective rate” is thus 6.17%, while 6% is termed the “nominal” rate. Similarly, a 6% bond on which interest is paid quarterly has an effective rate of 6.14%.
