where:

Principal = Initial investment amount
Rate = Interest rate per year
Time = Time period in years

Example

Suppose you invest ₹10,000 for 2 years at a rate of 5% per annum. What is the total amount after 2 years?

Total Amount = ₹10,000 + (₹10,000 x 5 x 2) / 100 = ₹10,500

Interest Earned = Total Amount - Principal Amount = ₹10,500 - ₹10,000 = ₹500

Interest Rate = Interest Earned / Principal Amount = 500 / 10,000 = 5.00%

Interest Rate = Interest Earned / Time Period = 500 / 2 = 250

Conclusion

Simple interest is a basic form of interest calculation that is commonly used in financial calculations. It is calculated on the principal amount only, regardless of the time period. The formula for simple interest is: Interest = (Principal × Rate × Time) / 100, where Principal is the initial investment amount, Rate is the interest rate per year, and Time is the time period in years.
