About This Calculator
Refinancing your mortgage can save thousands in interest payments, but it comes with closing costs. Our refinance calculator helps you determine whether refinancing makes financial sense by comparing your current loan terms with the proposed new loan.
The calculator computes monthly payments for both loans using the standard EMI formula: EMI = P x r x (1+r)^n / ((1+r)^n - 1), where P is the loan balance, r is the monthly interest rate, and n is the number of monthly payments. It then calculates your monthly savings, break-even period (the time needed for savings to cover closing costs), and total interest savings over the full loan term.
Refinancing is typically worth it when: current rates are at least 1-2% lower than your existing rate, you plan to stay in the home beyond the break-even point, or you want to switch from an adjustable-rate mortgage (ARM) to a fixed-rate loan. Our calculator provides a cumulative savings chart showing how your net savings grow month by month, helping you visualize when you recoup the closing costs and start saving.
Regional Notes
India: Home loan rates in India range from 8.5-10% depending on credit profile and lender. Refinance costs (balance transfer fees) are typically 0.5-2% of the outstanding loan amount. Processing fees, legal charges, and technical valuation fees apply. Many Indian banks offer balance transfer facilities with top-up loan options.
United States: Current 30-year fixed mortgage rates range from 6.5-7.5%. Closing costs average 2-5% of the loan amount ($4,000-7,000 typical). The IRS allows deduction of mortgage interest on refinanced loans. Cash-out refinancing is popular for debt consolidation or home improvements.
United Kingdom: Mortgage rates range from 4.5-6% for fixed-rate products. Arrangement fees, valuation fees, and legal costs typically total £1,000-3,000. Many UK lenders offer fee-free remortgage deals with slightly higher rates. The break-even analysis is crucial for UK borrowers due to product fees and early repayment charges.

Frequently Asked Questions
When should I refinance my mortgage?
You should consider refinancing when: 1) Current interest rates are at least 1-2% lower than your existing rate, 2) Your credit score has improved significantly, 3) You want to switch from adjustable to fixed rate, 4) You need to lower monthly payments, or 5) You want to change your loan term. A good rule is that monthly savings should cover closing costs within 2-3 years.
How to calculate refinance savings?
Refinance savings are calculated by comparing: total interest on the current loan minus total interest on the new loan minus closing costs. Monthly savings = Current EMI - New EMI. Break-even period = Total Closing Costs / Monthly Savings. Total interest savings accumulate over the remaining loan term after the break-even point.
What are closing costs in refinancing?
Closing costs in refinancing typically include: application fees, origination fees, appraisal fees, title search and insurance, credit report fees, attorney fees, recording fees, prepaid interest, and escrow deposits. In India, refinance costs are typically 0.5-2% of the loan amount. In the US, closing costs average 2-5% of the loan amount.
What is break-even period in refinancing?
The break-even period is the time it takes for the monthly savings from refinancing to equal the total closing costs paid. For example, if closing costs are ₹50,000 and monthly savings are ₹2,000, the break-even period is 25 months. If you plan to stay in the home beyond the break-even period, refinancing makes financial sense.
Is refinancing worth it for 1% rate difference?
A 1% rate reduction can be worth refinancing if you plan to stay in the home long enough to recover closing costs. On a ₹30,00,000 loan, a 1% reduction saves approximately ₹15,000-20,000 per year in interest. With closing costs of ₹50,000, the break-even would be about 2.5-3 years. Calculate your specific numbers to decide.
Can I refinance with bad credit?
Refinancing with bad credit is possible but may come with higher interest rates and stricter requirements. In India, a credit score below 700 may result in higher rates or rejection. In the US, FHA streamline refinance allows refinancing with scores as low as 580. In the UK, adverse credit mortgages exist but at higher rates. Improving your credit score before refinancing can save significantly on interest costs.
What is a cash-out refinance?
A cash-out refinance replaces your existing mortgage with a larger loan, allowing you to receive the difference in cash. For example, if you owe ₹30,00,000 on a home worth ₹50,00,000, you might refinance for ₹35,00,000 and receive ₹5,00,000 cash. This is commonly used for home renovations, debt consolidation, or major purchases. The new loan has a higher balance but potentially a lower rate.
How does refinancing affect my credit score?
Refinancing can temporarily lower your credit score by 5-10 points due to the hard inquiry from the lender. However, the impact is usually short-lived. In the long term, refinancing to a lower monthly payment can improve your debt-to-income ratio and payment history. The credit score typically recovers within 3-6 months of on-time payments on the new loan. Multiple applications within a 14-45 day window are usually counted as a single inquiry by credit bureaus.
