What happens to my EMI if interest rates increase?

If your loan is on a floating interest rate and the repo rate rises, your monthly EMI or loan tenure will increase to account for the higher interest cost.

Q: How is Loan EMI calculated?

Loan EMI is calculated using the formula: EMI = [P x R x (1+R)^N] / [(1+R)^N - 1], where P is Principal Loan Amount, R is Monthly Interest Rate, and N is Loan Tenure in months.

How is Loan EMI Calculated? (Formula & Example)

Equated Monthly Installment (EMI) is a fixed payment amount made by a borrower to a lender at a specified date each calendar month. EMIs apply to both interest and principal each month so that over a specified number of years, the loan is fully paid off.

Mathematical EMI Formula:

EMI = [P × R × (1+R)^N] / [(1+R)^N - 1]

Where:
• P = Principal Loan Amount
• R = Monthly Interest Rate (Annual Rate / 12 / 100)
• N = Loan Tenure in Months (Number of years × 12)

Example Calculation:

If you borrow a Home Loan of ₹30,00,000 at an annual interest rate of 8.5% for a tenure of 20 years (240 months):

P = ₹30,00,000
R = 8.5 / (12 × 100) = 0.007083
N = 240 months
Monthly EMI = ₹26,035
Total Interest Payable = ₹32,48,318
Total Payment = ₹62,48,318

Top 4 Tips to Lower Your Loan Interest Burden

Make Part-Prepayments Early: Even paying an extra 1 EMI every year or putting bonus money towards principal can reduce your tenure by 4 to 6 years.
Opt for a Shorter Tenure: While a longer tenure gives lower monthly EMIs, you end up paying significantly more in total interest. Choose the shortest tenure you can comfortably afford.
Maintain a High Credit Score (750+): Banks offer their lowest interest rate brackets to borrowers with excellent CIBIL / credit scores.
Refinance / Balance Transfer: If market rates drop, look into refinancing with another lender offering lower interest rates.

Frequently Asked Questions

Loan EMI is calculated using the standard amortized formula: EMI = [P × R × (1+R)^N] / [(1+R)^N - 1], where P is Principal Loan Amount, R is monthly interest rate, and N is tenure in months.

For floating rate loans, an interest rate increase typically increases your loan tenure while keeping EMI constant, or increases the monthly EMI amount if tenure cannot be extended further.

Yes! Making partial or full prepayments directly reduces the outstanding principal balance, which significantly cuts down total interest paid and shortens the tenure.

A Fixed Rate remains unchanged throughout the loan duration, providing predictable EMIs. A Floating Rate fluctuates according to RBI repo rate changes and market conditions.
