how to find the effective rate of interest

The effective interest rate (EIR) is an annual rate that reflects the effect of compounding in a year and results in the same future value of the money as compounding at the periodic rate for m times a year.

It applies to various credit arrangements, including loans, credit cards, and hire-purchase agreements. The Act requires lenders to provide clear and transparent information to consumers about the cost of credit, including the total amount repayable, the interest rate, and any fees or charges. It sets rules on credit advertising and marketing practices, ensuring that consumers are not misled or subjected to unfair practices.

This approach may limit the vehicles in which EAR is calculated or communicated. It represents the true annual interest rate after accounting for the impact of compounding interest, and it is typically higher than the nominal interest rate. The term “interest rate” is one of the most commonly used phrases in the fixed-income investment lexicon.

Still, it can result in large differences in your investment’s future value in the longer-term.

Besides, you can set the frequency of the interest capitalization or compounding frequency continuous as well. Mathematically speaking, the difference between the nominal and effective rates increases with the number of compounding periods within a specific time period. Before we talk about other rates adjusted by the above factors, it is practical to talk about an interest rate applied over a specific period. Although it can be done by hand, most investors will use a financial calculator, spreadsheet, or online program.
