Effective interest rate is the one which caters the compounding periods during a payment plan. It is used to compare the annual interest between loans with different compounding periods like week, month, year etc. ... The nominal interest rate is the periodic interest rate times the number of periods per year.

Nominal interest rates are not comparable unless their compounding periods are the same; effective interest rates correct for this by "converting" nominal rates into annual compound interest. In many cases, depending on local regulations, interest rates as quoted by lenders and in advertisements are based on nominal, not effective interest rates, and hence may understate the interest rate compared to the equivalent effective annual rate.

Re: Question

by LAUBEN HABUMUREMYI -
It’s important to know what type of interest you’re paying when you take out a mortgage. There are basically two types, but each of them is sometimes known by more than one name.
Nominal Interest Rate. Also known as simple interest rate. Nominal interest is calculated on the original principal only. If you borrow $100,000 for one year at 7%, you end up paying back $107,000.
Effective Interest Rate. Also known as compound interest. With effective interest, the interest rate is applied to the original principal AND all the accumulated interest. If you borrow $100,000 for one year at 7% and the interest is compounded semi-annually, you end up paying back $107,122.50. Therefore, the effective interest rate is actually 7.1225%. In Canada, this is known as the Annual Percentage Rate (APR) and it’s the rate that Canadian mortgage lenders are required to quote.
Of course, actual mortgages are more complicated than this because payments are made monthly (or even more frequently), rather than at the end of the year. But the result is still the same: the effective interest rate is slightly higher than the nominal interest rate.

The nominal interest rate, or coupon rate, is the actual price borrowers pay lenders, without accounting for any other economic factors.
The real interest rate accounts for inflation, giving a more precise reading of a borrower's buying power after the position has been redeemed.

Re: Question

by DANIEL DUSENGIMANA -
An interest rate takes two forms: nominal interest rate and effective interest rate. The nominal interest rate does not take into account the compounding period. The effective interest rate does take the compounding period into account and thus is a more accurate measure of interest charges.

A statement that the "interest rate is 10%" means that interest is 10% per year, compounded annually. In this case, the nominal annual interest rate is 10%, and the effective annual interest rate is also 10%. However, if compounding is more frequent than once per year, then the effective interest rate will be greater than 10%. The more often compounding occurs, the higher the effective interest rate.

The relationship between nominal annual and effective annual interest rates is:

ia = [ 1 + (r / m) ] m - 1

where "ia" is the effective annual interest rate, "r" is the nominal annual interest rate, and "m" is the number of compounding periods per year.

Example: A credit card company charges 21% interest per year, compounded monthly. What effective annual interest rate does the company charge?

r = 0.21 per year

m = 12 months per year

ia = [ 1 + (.21 / 12) ] 12 - 1

= [1 + 0.0175 ] 12 - 1

= (1.0175)12 - 1 = 1.2314 - 1

= 0.2314 = 23.14%

It may be desired to find the effective interest rate for a period other than annual. In this case, adjust the period for "r" and "m" as needed. For example, if the effective interest rate per semi annual period (every 6 months) is desired, then

r = nominal interest rate per 6 months

m = number of compounding periods per 6 months

and the effective interest rate, isa, per semi-annual period, is:

isa = [ 1 + (r / m) ] m - 1

A real interest rate is an interest rate that has been adjusted to remove the effects of inflation to reflect the real cost of funds to the borrower and the real yield to the lender or to an investor. A nominal interest rate refers to the interest rate before taking inflation into account. Nominal can also refer to the advertised or stated interest rate on a loan, without taking into account any fees or compounding of interest.

Nominal interest rate is also defined as a stated interest rate. This interest works
according to the simple interest and does not take into account the compounding periods.
Effective interest rate is the one which caters the compounding periods during a payment
plan. It is used to compare the annual interest between loans with different compounding
periods like week, month, year etc. In general stated or nominal interest rate is less than
the effective one. And the later depicts the true picture of financial payments.
The nominal interest rate is the periodic interest rate times the number of periods per
year. For example, a nominal annual interest rate of 12% based on monthly compounding
means a 1% interest rate per month (compounded). A nominal interest rate for
compounding periods less than a year is always lower than the equivalent rate with
annual compounding (this immediately follows from elementary algebraic manipulations
of the formula for compound interest). Note that a nominal rate without the compounding
frequency is not fully defined: for any interest rate, the effective interest rate cannot be
specified without knowing the compounding frequency and the rate. Although some
conventions are used where the compounding frequency is understood, consumers in
particular may fail to understand the importance of knowing the effective rate.
Nominal interest rates are not comparable unless their compounding periods are the
same; effective interest rates correct for this by "converting" nominal rates into annual
compound interest. In many cases, depending on local regulations, interest rates as
quoted by lenders and in advertisements are based on nominal, not effective interest rates,
and hence may understate the interest rate compared to the equivalent effective annual
rate.
The term should not be confused with simple interest (as opposed to compound interest)
which is not compounded.
The effective interest rate is always calculated as if compounded annually. The effective
rate is calculated in the following way, where ie is the effective rate, r the nominal rate
(as a decimal, e.g. 12% = 0.12), and “m” the number of compounding periods per year
(for example, 12 for monthly compounding):
ie = (1 + r/m)m - 1

Nominal and Effective Interest Rates
Go to questions covering topic below

An interest rate takes two forms: nominal interest rate and effective interest rate. The nominal interest rate does not take into account the compounding period. The effective interest rate does take the compounding period into account and thus is a more accurate measure of interest charges.

A statement that the "interest rate is 10%" means that interest is 10% per year, compounded annually. In this case, the nominal annual interest rate is 10%, and the effective annual interest rate is also 10%. However, if compounding is more frequent than once per year, then the effective interest rate will be greater than 10%. The more often compounding occurs, the higher the effective interest rate.

The relationship between nominal annual and effective annual interest rates is:

ia = [ 1 + (r / m) ] m - 1

where "ia" is the effective annual interest rate, "r" is the nominal annual interest rate, and "m" is the number of compounding periods per year.

Example: A credit card company charges 21% interest per year, compounded monthly. What effective annual interest rate does the company charge?

r = 0.21 per year

m = 12 months per year

ia = [ 1 + (.21 / 12) ] 12 - 1

= [1 + 0.0175 ] 12 - 1

= (1.0175)12 - 1 = 1.2314 - 1

= 0.2314 = 23.14%

It may be desired to find the effective interest rate for a period other than annual. In this case, adjust the period for "r" and "m" as needed. For example, if the effective interest rate per semi annual period (every 6 months) is desired, then

r = nominal interest rate per 6 months

m = number of compounding periods per 6 months

and the effective interest rate, isa, per semi-annual period, is:

isa = [ 1 + (r / m) ] m - 1
