Understanding Interest Rate Per Month

A period of one month can be called an interest rate per month.

Annual Interest Rate (APR): This is how much interest one pays from lending or earns from deposits over a yearly basis.

Monthly Interest Rate: This is the interest rate charged against a given balance over a month. It is a fraction of the annual interest rate.

There are two types of interest rates, and they are simple and compound. Now, let’s understand them one by one.

Formula to Find Monthly Interest Rate

1. Formula to find Simple Interest

The formula to calculate simple interest is given below:

Where,

• SI = Simple Interest
• P = Principal Amount
• R = Annual Interest Rate (in %)
• T = Time Period (in years)

To calculate the monthly interest, we simply divide the annual rate by 12:

Example Calculation (Simple Interest) If you borrow ₹10,000 as loan for six months at an annual interest rate of 12%.

Monthly Interest Rate = 12% ÷ 12 = 1% per month

Interest for 6 months = (10,000 × 12 × 0.5) / 100 = ₹600

Total to be paid after 6 months = ₹10,600

2. Compound Interest Formula

Compound interest is defined as:

• A = Final Amount
• P = Principal Amount
• r = Annual Interest Rate (decimal)
• n = Compounding periods per year
• t = Time expressed in years

Compound Interest Example

Let you deposit the amount of principal ₹5,000 at an annual interest rate is 12%. And compounded by compounding of the interest half-yearly it may take 1 year. so,  12 %  ÷12=1 %or  0.01 (decimal form) Compound Interest Formula: So, interest at one end= ₹5,634- ₹5,000= ₹ 634.

Why the Calculation of the interest is taken as monthly?

1. Better Financial Planning

This amount of monthly interest will then be used while planning the cost side and investing side.

2. Loan Management

The idea of monthly interest in loans will allow comparisons to be made regarding the offers made by a bank before finalizing a loan.

3. Investment Decisions
