Invest NowSimple Interest (SI) is the interest calculated only on the principal amount over a specific period at a fixed rate. It follows a linear growth pattern, meaning the interest remains the same for each period. The formula for simple interest is:
SI = (P×R×T) / 100
Where:
For example, if ₹10,000 is invested at a 5% annual interest rate for 3 years, the interest earned will be:
SI = (10,000×5×3) / 100 = ₹1,500
Unlike compound interest, simple interest does not accumulate over time, making it ideal for short-term loans and fixed deposits.
A Simple Interest Calculator is an online tool that helps users calculate the interest earned or payable on a principal amount over a given period at a fixed interest rate. It eliminates manual calculations and ensures accuracy. By entering the principal amount (P), interest rate (R), and time period (T), users can instantly determine:
This tool is useful for loans, fixed deposits, savings accounts, and other financial calculations. The Jainam Simple Interest Calculator simplifies financial planning by providing quick and precise results without complex mathematical formulas.
The formula for Simple Interest (SI) is:
SI = (P×R×T) / 100
Where:
For example, if ₹50,000 is deposited at an 8% annual interest rate for 5 years, the interest calculation is:
SI = (50,000×8×5) / 100 = ₹20,000
The total amount after 5 years will be:
Maturity Amount = P+SI = 50,000+20,000 = ₹70,000
This formula is widely used in bank loans, fixed deposits, and savings accounts.
A Simple Interest Calculator automates the SI formula and provides instant results. Users need to:

The Jainam Simple Interest Calculator simplifies financial planning by eliminating manual calculations and providing error-free results.
Using a Simple Interest Calculator provides several benefits:
For example, if a person wants to compare loan interest from two banks, the Jainam Simple Interest Calculator can help by calculating the total interest payable for different rates and tenures.
Simple Interest (SI) is calculated only on the principal amount, while Compound Interest (CI) is calculated on both the principal and accumulated interest.
Formula differences:
For example, a ₹10,000 investment at 5% for 3 years:
Thus, compound interest results in higher returns over time due to interest compounding.
Yes, a Simple Interest Calculator is useful for calculating loan interest, especially for short-term personal loans, car loans, and education loans that use simple interest.
For example, if you borrow ₹1,00,000 at 7% annual interest for 2 years, the interest is:
SI = (1,00,000×7×2) / 100 = ₹14,000
So, the total repayment amount = ₹1,00,000 + ₹14,000 = ₹1,14,000.
However, most long-term loans, like home loans and business loans, use compound interest, so checking the loan type is essential.
Yes, for short-term Fixed Deposits (FDs) that use simple interest, this calculator is useful. However, most bank FDs apply compound interest.
For example, a 6-month FD of ₹50,000 at 6% annual interest:
SI = (50,000×6×0.5) / 100 = ₹1,500
So, the maturity amount will be:
50,000+1,500=₹51,500
For longer-term FDs, using a Compound Interest Calculator is more suitable.
No, Simple Interest cannot be negative, as it represents the interest earned on savings or the interest payable on a loan. However, in cases of prepaid interest (where a borrower pays interest upfront), it may seem like the calculated interest reduces over time, but the actual value remains non-negative.
If a bank deducts an amount from early loan repayments, it’s usually a prepayment penalty rather than a negative interest rate.
Simple Interest increases linearly with time. If the principal and interest rate remain the same, interest will increase proportionally to time.
For example, if ₹10,000 at 5% interest is kept for:
This means the longer the time period, the higher the total interest earned/payable.
To calculate monthly simple interest, use the formula SI = (P × R × T) / 100, where T is in months. Convert the annual interest rate to a monthly rate by dividing by 12.
The two types are ordinary simple interest, calculated using a 360-day year, and exact simple interest, calculated using a 365-day year. Both methods apply the standard formula but differ in time calculation.
The simple interest formula is SI = (P × R × T) / 100, where P is the principal, R is the annual interest rate, and T is the time in years.
No, in simple interest, the interest rate remains constant, and the interest is only calculated on the original principal amount throughout the tenure.
A simple interest calculator is an online tool that helps compute the total interest and final amount payable based on the principal, rate, and tenure.
Enter the principal amount, interest rate, and loan tenure into the calculator. It will instantly compute the interest and total payable amount.
No, simple interest cannot be negative. However, in cases of refunds or reversals, the payable amount may reduce, but the actual interest calculation remains positive.
Yes, when calculating months, the time (T) should be converted into years by dividing by 12. The formula remains the same but adjusted for the appropriate time frame.
Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and accumulated interest, leading to higher returns over time due to the effect of compounding.
