Understanding Simple Interest
Simple Interest (SI) is a straightforward method of calculating the interest charge on a loan or the return on an investment. Unlike compound interest, where interest is calculated on both the principal and the accumulated interest, simple interest is determined solely on the initial principal amount. This makes it a popular choice for short-term loans and certain types of savings instruments.
What is the Simple Interest Formula?
The Simple Interest formula is used to compute the interest accrued over a specific period. It is represented as:
Simple Interest Formula
The formula is straightforward:
The Formula:
- SI= (P × R × T) / 100
- A= P + SI
- Where:
- P= Principal Amount (Initial Investment/Loan)
- R= Rate of Interest per annum (%)
- T= Time Period (in years)
- A= Total Maturity Amount
Calculation Example
Let's assume Mr. A invests ₹15,000 at an interest rate of 5% for 2 years.
- Principal (P): ₹15,000
- Rate (R): 5%
- Time (T): 2 Years
- Interest (SI) = (15000 × 5 × 2) / 100 = ₹1,500
- Total Amount (A) = 15000 + 1500 = ₹16,500

Frequently Asked Questions
What can I determine with this calculator?
You can determine the total interest payable/receivable on a principal amount as well as the total maturity value after a specific tenure.
Does the interest rate change over time in SI?
No, in Simple Interest calculations, the interest is always calculated on the original principal amount. It remains constant throughout the tenure unless the rate itself is revised.
Is Simple Interest better than Compound Interest?
For borrowers, Simple Interest is generally better as the total repayment is lower compared to compound interest. For investors, Compound Interest is superior as it allows wealth to grow exponentially.
