The effective interest rate (EIR), effective annual interest rate, annual equivalent rate (AER) or simply effective rate is the percentage of interest on a loan or financial product if compound interest accumulates in periods different than a year. [1] It is the compound interest payable annually in arrears, based on the nominal interest rate ...
For example, if you take out a five-year loan for $20,000 and the interest rate on the loan is 5 percent, the simple interest formula would be $20,000 x .05 x 5 = $5,000 in interest. Who benefits ...
The annual effective discount rate expresses the amount of interest paid or earned as a percentage of the balance at the end of the annual period. It is related to but slightly smaller than the effective rate of interest, which expresses the amount of interest as a percentage of the balance at the start of the period.
The effective interest rate is always calculated as if compounded annually. The effective rate is calculated in the following way, where r is the effective rate, i the nominal rate (as a decimal, e.g. 12% = 0.12), and n the number of compounding periods per year (for example, 12 for monthly compounding):
The average savings account annual percentage yield in April 2023 is only 0.39%. This number includes low interest rates from traditional banks as well as higher savings rates from online banks and...
The term annual percentage rate of charge (APR), [1] [2] corresponding sometimes to a nominal APR and sometimes to an effective APR (EAPR), [3] is the interest rate for a whole year (annualized), rather than just a monthly fee/rate, as applied on a loan, mortgage loan, credit card, [4] etc. It is a finance charge expressed as an annual rate.
This is a reasonable approximation if the compounding is daily. Also, a nominal interest rate and its corresponding APY are very nearly equal when they are small. For example (fixing some large N), a nominal interest rate of 100% would have an APY of approximately 171%, whereas 5% corresponds to 5.12%, and 1% corresponds to 1.005%.
My understanding of the relation between effective (i) and nominal (r) interest rate is e^r=(1+(i/n))^n. I see 1+(i/n) as the base b such that e^r=b^n. This is important because it allows any discrete calculation of interest in terms of (i) to be expressed as a continuous calculation in terms of base e and nominal interest rate (r).
