Simple Interest Calculator

Whenever we lend money, invest money or put money in a fixed deposit, one thing comes to our mind.
“How much extra money will I get?”
Let us say you invest ₹1 lakh, and the person says they will give you 8% interest.
But what does that actually mean?
How much money will you earn after 1 year?
What about after 3 years?
And how much money will you receive in total?
This is where most people get confused.
Not because the calculation is difficult, but because nobody wants to sit and calculate it manually every time.
That is why Definedge brings a FREE Simple Interest Calculator, and it helps you calculate the interest and total amount in just a few seconds.
What is a Simple Interest Calculator?
Definedge’s Simple Interest Calculator is an online tool that helps you calculate the interest earned on a principal amount over a period of time.

You just enter:
– Principal amount
– Interest rate
– Time period

And the calculator will show:
– Interest earned
– Total repayment amount
– Total interest on the overall amount.

How does the Simple interest calculator work?
The calculator is powered with a simple formula:
Simple Interest = (P × R × T) ÷ 100
Where,
P = Principal Amount
R = Interest Rate
T = Time Period
Based on these values, the calculator instantly calculates the interest amount.
Let us take an example
Suppose you invest ₹1,00,000 in a bank receipt.
Interest Rate = 8%
Time Period = 5 Years

Calculation:
Simple Interest = (100000 × 8 × 5) ÷ 100
Simple Interest = ₹40,000
Total Amount = ₹1,40,000
This means your investment of ₹1 lakh earns ₹40,000 as interest in 5 years.
So at the end of 5 years, you receive ₹1,40,000.
