What is an EMI calculator?
An EMI calculator is a free online tool that tells you the fixed monthly amount you will need to repay on a loan.
EMI stands for Equated Monthly Instalment — the single payment you make every month to your lender until the loan is fully repaid. Each EMI covers two things: a portion of the principal you borrowed, and the interest charged on the outstanding balance.
The Chola Securities EMI calculator instantly shows your monthly repayment, the total interest payable over the tenure, and the total amount you will pay back across the life of the loan.
How does the EMI calculator work?
EMIs on most retail loans are calculated on a reducing-balance basis. This means interest for each month is charged only on the loan amount that is still outstanding. As you repay, the outstanding principal falls, the interest portion of every EMI shrinks, and the principal portion grows — while the EMI itself stays constant throughout the tenure.
The calculator uses the standard reducing-balance EMI formula:
EMI = P × i × (1 + i)n ÷ [(1 + i)n − 1]
| Variable | Meaning |
|---|
| P | Loan amount (principal) |
| i | Monthly interest rate (annual rate ÷ 12 ÷ 100) |
| n | Tenure in months |
Total interest = (EMI × n) − P
Worked example: Home loan of ₹25,00,000 at 9% per annum for 20 years (240 months). Monthly rate i = 9 ÷ 12 ÷ 100 = 0.0075. Applying the formula, the EMI works out to approximately ₹22,493 per month. Over 240 months, total payment = ₹53,98,000, of which ₹28,98,000 is interest — meaning the interest alone is nearly as large as the original loan amount.
Note: the output is an estimate for illustration only. Actual EMI may differ based on the lender's rounding conventions, processing charges, and applicable fees. This is not financial or lending advice.
How do I use Chola Securities' EMI calculator?
Using the calculator takes three steps.
- Enter the loan amount — the total amount you wish to borrow.
- Enter the interest rate — the annual rate offered by your lender.
- Enter the loan tenure — the repayment period in years or months.
The calculator instantly shows your monthly EMI, total interest payable, and total repayment amount. Adjust any input to compare scenarios — try a higher down payment, a different tenure, or an alternative interest rate to see the impact in real time.
Why use the EMI calculator?
- Know your exact monthly commitment before signing a loan agreement.
- Compare different loan amounts, rates, and tenures to find the most affordable option.
- See the real cost of borrowing — not just the principal, but the total interest you will pay over the life of the loan.
- Decide how large a down payment to make by testing how it reduces your EMI and total interest.
- Plan your monthly budget around a fixed, known repayment obligation before applying.
