Loan Refinance Calculator
Wondering if refinancing your loan could save you money? Our Loan Refinance Calculator helps you compare your current loan with a potential refinanced option, giving you a clear picture of whether the switch makes financial sense. Just enter your current loan details (remaining balance, interest rate, and tenure) along with the new refinanced loan terms. The calculator instantly shows you the EMI difference, total interest savings, total cost of refinancing (including closing costs and fees), the break-even point, and a complete side-by-side comparison. Whether you're refinancing a mortgage, auto loan, personal loan, or student loan, this tool gives you the data you need to make an informed decision.
What Is
Loan refinancing is the process of replacing an existing loan with a new loan that has different terms — typically a lower interest rate, a different tenure, or both. The new loan pays off the old one, and you begin making payments under the new agreement. Refinancing is common for mortgages (where rates can differ significantly over time), auto loans (when credit scores improve), personal loans (when market rates drop), and student loans (when switching from private to federal or vice versa). The key financial question in refinancing is whether the interest savings outweigh the total cost of refinancing. Refinancing costs can include: origination fees (0.5-1.5% of the loan amount), appraisal fees ($200-$600 for mortgages), title search and insurance ($500-$1,500), legal fees, prepayment penalties on the old loan, and various administrative charges. For example, refinancing a $200,000 mortgage from 7.5% to 6.0% over 25 years reduces the monthly EMI from $1,487 to $1,288 — a saving of $199/month. Over 25 years, that's $59,700 in gross savings. If refinancing costs total $5,000, your net saving is $54,700, and you break even in about 25 months.

Frequently Asked Questions
What is the difference between refinancing and a balance transfer?
A balance transfer moves your existing loan to a new lender with better terms, while refinancing replaces your existing loan with an entirely new loan — which can be with the same lender or a different one. In practice, the terms are often used interchangeably, but technically, refinancing involves creating a new loan agreement with new terms (rate, tenure, or both), whereas a balance transfer may simply move the existing balance to a new lender's product.
When does refinancing make financial sense?
Refinancing typically makes sense when the new interest rate is at least 0.75-1% lower than your current rate, you plan to stay in the home or keep the asset long enough to pass the break-even point, your credit score has improved since the original loan, and the total refinancing costs are reasonable relative to the interest savings. For mortgages, a common rule of thumb is to refinance if you can reduce your rate by at least 1%.
How much does it cost to refinance a loan?
Refinancing costs vary significantly by loan type. For mortgages, expect to pay 2-5% of the loan amount in closing costs ($4,000-$10,000 on a $200,000 loan). For personal loans, refinancing costs are typically lower — often just an origination fee of 1-3% ($100-$300 on a $10,000 loan). Auto loans may have minimal refinancing costs. Some lenders offer no-closing-cost refinances, but these usually come with a slightly higher interest rate.
How long does the refinancing process take?
The timeline varies by loan type. Personal loan refinancing is typically the fastest — often 1-5 business days from approval to disbursement. Auto loan refinancing takes 1-2 weeks. Mortgage refinancing is the slowest, typically taking 30-45 days from application to closing, though some lenders offer fast-track options in 2-3 weeks.
Will refinancing affect my credit score?
Yes, temporarily. When you apply for refinancing, the lender performs a hard inquiry on your credit report, which can lower your score by 5-10 points temporarily. Opening a new loan also reduces your average account age, which may cause a small dip. However, if refinancing results in lower monthly payments and you make them on time, your credit score may actually improve over time due to lower credit utilization.
Can I refinance with bad credit?
It's possible but challenging. Most lenders prefer borrowers with credit scores of 670 or above for refinancing. With scores between 580-669, you may still qualify but at higher interest rates. Below 580, options are limited to FHA streamline refinances (for mortgages) or specialized lenders. Before applying, check your credit report for errors and consider waiting a few months to improve your score.
