Before you take a loan or invest your money, one question is worth asking: how much will you pay or earn in interest over time?
Simple interest is a method where interest is calculated only on the original principal amount, without compounding. It is commonly used in short-term loans, certain fixed deposits, and other basic financial arrangements.
Working this out manually is straightforward in theory, but easy to get wrong. A Simple Interest Calculator helps you instantly determine the interest amount and total payable value based on:
- Principal amount
- Rate of interest
- Time period
With just three inputs, you can see how much interest you will pay on a loan or earn on an investment.
Simple Interest Formula
Simple Interest is calculated using this formula:
SI = (P X R X T) / 100
Where:
- P = Principal amount
- R = Rate of interest per annum
- T = Time period (in years)
To calculate the total amount after interest:
Total Amount = P+SI
Example
Let’s use the values shown:
- Principal (P) = ₹10,000
- Rate of Interest (R) = 6.5% per annum
- Time (T) = 5 years
Step 1: Calculate Simple Interest
SI = (10,000 × 6.5 × 5)/100
SI = 3,25,000/100
SI = ₹3,250
Step 2: Calculate Total Amount
Total = 10,000 + 3,250
Total = ₹13,250
