Simple Interest Calculator

While availing any loan or making investment, understanding how interest works is essential in managing your finances effectively. One of the most basic types of interest calculations is simple interest. Chartered ONE offers an easy-to-use online Simple Interest Calculator to simplify your financial planning. With just a few clicks, you can quickly calculate how much interest you will earn. This will help you make informed decisions about loans or investments. It’s fast, convenient and perfect for accurate calculations.

What is Simple Interest? 

Simple interest is the rate at which you borrow or lend money. It calculates the interest on the principal amount over a set period. When someone borrows money (the principal amount), they repay it over time with an extra amount called interest. 

The formula for simple interest is: SI = P x R x T / 100

Where, 

SI stands for Simple Interest which is the total interest earned or paid. 

P is the Principal Amount that was borrowed or invested. 

R represents the Rate of Interest in percentage.

T signifies the Time for which the interest is calculated (in years).

Once you get the Simple Interest (SI) you can find the Total Amount (A) by adding it to the principal: A = P + SI

Alternatively, a simple interest calculator can directly give you the total amount using the formula  A = P (1 + rt)

So, to make the process easier, use a simple interest calculator also known as Interest Rate Calculator. 

How Chartered ONE’s Simple Interest Calculator Works?

Using a simple interest calculator is simple with Chartered ONE. You will need to input three key details to use this calculator:

Enter the Principal Sum (P): This is the original amount of the loan or investment. 

Input the Interest Rate (R): Use our rate tables to find out the rate of return on your investment in percentage.

Select the Time Period (T): Choose the duration for which the loan or investment is active. It is usually expressed in years. 

Calculate the Interest: Once the above details are filed in, the calculator will display the total interest earned or payable. 

Example of Simple Interest Calculation

Let’s say you invest Rs 1,000 at an annual interest rate of 5% for 3 years. Now, using the formula SI = (1000 x 5 x 3) / 100, the total interest earned on your investment will be Rs 150. 

If you use this simple online tool, you need to enter only the values and get the accurate result instantly.

When Should You Use Simple Interest Calculator

A Simple Interest Calculator can be used in various situations:

Personal Loans: To figure out how much interest you will pay on a loan over a set period. 

Investments: To estimate the return on investment (ROI) when investing in fixed deposits or bonds that follow simple interest calculations. 

Educational Loans: To understand how much interest you will be charged on student loans. 

Savings Accounts: Some savings accounts offer simple interest rather than compound interest. This calculator helps estimate earnings. 

Short Term Loans: Simple interest is often applied to short term loans like car loans, business loans and personal loans. 

Simple Interest vs Compound Interest

The primary difference between simple and compound interest is that simple interest is calculated only on the principal amount while compound interest is calculated on the principal and the accumulated interest. Over time, compound interest grows more quickly because of this "interest on interest” effect. However, for short term interest loans or investments, simple interest is the preferred method due to its straightforward nature.
