Loan Refinance Calculator — Free Online Tool to Compare Refinancing Options
Introduction
Refinancing a loan means replacing your existing loan with a new one — usually to get a lower interest rate, a different tenure, or better repayment terms. Whether you're refinancing a home loan, personal loan, or auto loan, the key question is always the same: will the new loan actually save you money once you factor in the new EMI, the new tenure, and the total interest paid over the loan's lifetime? The Loan Refinance Calculator answers that instantly. Enter your current loan details alongside the terms of the new loan you're considering, and the calculator compares both EMIs and total repayment amounts side by side, showing you the exact savings — or extra cost — of switching.
How to Use the Loan Refinance Calculator
- Current Loan Balance — enter the outstanding principal on your existing loan (e.g. ₹500,000).
- Current Interest Rate (%) — enter the annual interest rate on your existing loan (e.g. 10%).
- Remaining Term (Years) — enter how many years are left on your current loan (e.g. 5 years).
- New Interest Rate (%) — enter the interest rate being offered on the refinanced loan (e.g. 8%).
- New Loan Term (Years) — enter the repayment period for the new loan (e.g. 5 years).
- Click Compare & Calculate to instantly see your current EMI, refinanced EMI, total repayment under both loans, and your total savings.
Formula & Methodology
The calculator uses the standard EMI (Equated Monthly Installment) formula used by Indian banks and NBFCs:
EMI = [P × R × (1+R)N] / [(1+R)N − 1]
- P = Principal loan amount
- R = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- N = Total number of monthly installments (years × 12)
The calculator computes this EMI once for your current loan and once for the proposed refinanced loan, then multiplies each EMI by its number of months to get the total repayment under both scenarios. The difference between the two totals is your net savings (or added cost) from refinancing.
Worked Example
Suppose you have a loan with the following details:
- Current Loan Balance: ₹5,00,000
- Current Interest Rate: 10% per annum
- Remaining Term: 5 years
- New Interest Rate (refinance offer): 8% per annum
- New Loan Term: 5 years
Using the EMI formula above:
- Current EMI = ₹10,623.52/month → Total repayment = ₹6,37,411.34
- Refinanced EMI = ₹10,138.20/month → Total repayment = ₹6,08,291.83
- Total Savings = ₹29,119.51 over the 5-year term
Even a 2 percentage-point drop in interest rate can save tens of thousands of rupees over the loan tenure — which is why comparing offers before refinancing is essential.
Frequently Asked Questions
Q1. Is refinancing always worth it if the new interest rate is lower?
Not always. A lower rate helps, but if the new loan tenure is longer than your remaining term, you
could end up paying more in total interest even at a lower rate. Always compare total repayment
amounts, not just the EMI or the interest rate alone — which is exactly what this calculator shows.
Q2. Does this calculator include processing fees or foreclosure charges?
No. This calculator compares EMI and interest cost only. Most Indian lenders charge a foreclosure
fee on the old loan (typically 2–5% of the outstanding balance for fixed-rate loans; RBI rules
exempt floating-rate retail loans from foreclosure charges) and a processing fee on the new loan
(usually 0.5–2%). Subtract these one-time costs from your calculated savings to get the true net
benefit.
Q3. Can I use this calculator for any loan type, not just home loans?
Yes. The formula and comparison logic apply to any EMI-based loan — home loans, personal loans, car
loans, or business loans — as long as you know the outstanding balance, current rate, remaining
term, and the new loan's proposed rate and term.
