Simple interest is a way to calculate interest based on the initial principal amount. It refers to the extra amount added to the original principal that you need to pay back to the lender at the end of the term. This calculation method focuses solely on the original principal when determining the interest on a loan or investment.

For example, if you invest ₹10,000 at an 8% simple interest rate, you’ll earn ₹800 each year as interest. This means you’ll get ₹800 every year until your investment ends. At the end of the period, you’ll get back the ₹10,000 you initially invested, plus all the interest you earned over time.
 

A simple interest calculator is an online tool that helps you quickly figure out how much interest you'll earn or pay on a loan or investment. Instead of doing the math yourself, which can take time and effort, you can use this calculator to get the answer in seconds.

When you invest money or take out a loan with simple interest, the interest is calculated only on the original amount not on any interest that builds up over time. This is common with things like savings accounts or certain types of loans. By using a basic interest calculator, you can easily see how much interest you'll earn or pay over the term of the loan or investment.

This tool is especially useful if you're planning to borrow or invest money and want a clear picture of the costs or returns. It saves you time and ensures your calculations are accurate, so you can make informed financial decisions. Whether you're looking at savings, loans, or other financial products that use simple interest, this calculator makes it easy to see the outcome.
 

Simple interest is calculated using this formula:

SI = P × R × T

Where:

SI is the Simple Interest
P is the Principal amount (the initial amount borrowed or invested)
R is the Interest Rate (expressed as a decimal)
T is the Time period (in years)

Example

If you invest ₹1,00,000 at an 8% annual interest rate for 2 years, the interest earned will be:

SI = 1,00,000 × 0.08 × 2 = ₹16,000

This means you will earn ₹16,000 in interest over 2 years.

Maturity Amount

The maturity amount is the total amount you'll receive or owe including both the principal and the interest. It’s calculated with this formula:

A = P + SI
or
A = P × (1 + RT)

Where:

A is the Maturity Amount
P is the Principal amount
R is the Interest Rate
T is the Time period

Example

For the same investment of ₹1,00,000 at an 8% interest rate for 2 years:

1. Calculate the interest: ₹16,000 (as shown above).
2. Add the interest to the principal:

A = 1,00,000 + 16,000 = ₹1,16,000

So, the maturity amount will be ₹1,16,000.

Finding Principal, Rate, or Time

You can rearrange the formulas to find the Principal, Rate or Time if you know the others:

1. To find Principal (P): P = A / (1 + RT)

2. To find Rate (R): R = (1/T) × (A/P - 1)

3. To find Time (T): T = (1/R) × (A/P - 1)
 

A simple interest calculator helps you find out how much money you'll have in total after adding interest to your initial amount. It uses this formula:

Total Amount (A) = Principal (P) × (1 + Rate × Time)

P is the initial amount of money you start with.
Rate is the interest rate.
Time is the number of years.

For example, if you start with Rs 10,000, have an interest rate of 10%, and the money is invested for 6 years, you can use the formula to find out:

Total Amount (A) = 10,000 × (1 + 0.1 × 6)
Total Amount (A) = 10,000 × 1.6
                                = Rs 16,000

So, after 6 years, you'll have Rs 16,000 in total.

To find out how much interest you earned:

Interest = Total Amount - Principal
Interest = 16,000 - 10,000
                = Rs 6,000

So, you earned Rs 6,000 in interest.
