When should you refinance your mortgage?
Refinancing replaces your existing mortgage with a new loan, typically at a lower interest rate. The key question is whether the monthly savings from the lower rate justify the upfront closing costs and the time it takes to recoup them (the break-even point). See also: the Mortgage & Home Loan Calculator and the Mortgage Payoff Calculator.
The break-even calculation
Break-Even Months = Closing Costs ÷ Monthly Savings
If closing costs are $4,500 and monthly savings are $180, break-even = 25 months. If you plan to stay in the home for more than 25 months, refinancing saves money. If you plan to sell or move within 2 years, the costs outweigh the savings.
When refinancing makes sense
- Your new rate is at least 0.75–1% lower than your current rate (the traditional rule of thumb)
- You plan to stay in the home longer than the break-even period
- You want to switch from an adjustable-rate mortgage (ARM) to a fixed-rate for payment certainty
- You need to access home equity (cash-out refinance)
- You want to shorten the loan term to pay off faster
Refinancing costs to expect
- Application fee: $75–$500
- Origination fee: 0.5–1% of loan amount ($1,400–$2,800 on $280k)
- Appraisal fee: $300–$700
- Title insurance and search: $700–$900
- Attorney/settlement fees: $500–$1,000
- Total typical closing costs: 2–5% of loan amount

Frequently asked questions about mortgage refinancing
Can I refinance with bad credit? Yes, but at higher rates. FHA streamline refinance allows refinancing with minimal credit checks if you already have an FHA loan. Conventional refinancing typically requires a 620+ credit score for approval; 740+ for best rates.
How long does refinancing take? Typically 30–60 days from application to closing. Some lenders offer streamlined programs that close in 2–3 weeks. Gather documents early: tax returns, pay stubs, bank statements, current mortgage statement.
Is a 15-year or 30-year refinance better? A 15-year refinance has higher monthly payments but builds equity faster and saves substantially in total interest. A 30-year refinance maximises monthly savings. Use this calculator to compare both options for your specific balance.

Refinancing checklist — 12 questions to ask before you proceed
- How long do I plan to stay in this home? (Must exceed break-even period)
- What are the total closing costs — not just the rate?
- Is the new loan fixed or adjustable rate?
- Will the loan term reset to 30 years? (This can increase total interest paid even with a lower rate)
- Does my current loan have a prepayment penalty?
- What is my current home equity? (Below 20% may require PMI on the new loan)
- Has my credit score improved since the original loan?
- Are current market rates significantly lower than my rate?
- Do I qualify for a no-closing-cost refinance? (Higher rate, no upfront costs)
- Am I considering a cash-out refinance? (Different considerations apply)
- What is my debt-to-income ratio now vs when I got the original loan?
- Have I compared at least 3–5 lenders? (Rate differences of 0.5% are common)
When does refinancing make financial sense?
The break-even point determines whether refinancing is worthwhile: divide closing costs by monthly savings to find months to recoup. If you plan to stay in the property beyond the break-even point, refinancing saves money.
| Scenario | Current Rate | New Rate | Monthly Saving | Closing Costs | Break-even |
|---|---|---|---|---|---|
| 0.5% rate drop | 9.5% | 9.0% | ≈₹2,800 on ₹50L | ₹30,000 | ≈11 months |
| 1.0% rate drop | 9.5% | 8.5% | ≈₹5,600 on ₹50L | ₹30,000 | ≈5 months |
| Tenure extension | Any | Same | Lower EMI | Fee paid | Never (pays more total) |
India home loan refinancing: process and costs
In India, refinancing a home loan is called a "balance transfer." You approach a new lender who pays off your existing loan balance; you then repay the new lender at the lower rate. Costs involved: processing fee of new lender (0.25–1% of outstanding balance), legal and valuation charges (₹5,000–15,000), prepayment penalty from existing lender (usually nil for floating-rate loans per RBI guidelines, but check your agreement), and stamp duty on new agreement (some states). RBI mandates: banks cannot charge a prepayment penalty on floating-rate home loans. NBFCs may charge 1–2% prepayment penalty — confirm before initiating the transfer.

What does a home loan balance transfer cost in India?
Indian refinancing — balance transfer in bank parlance — carries lighter friction than US closings but is not free: processing fees of 0.25–0.5% (often capped ₹10,000–25,000 and frequently negotiable to zero in transfer offers), legal and valuation charges of ₹5,000–15,000, stamp duty on the new mortgage deed in some states, and CERSAI plus documentation charges. Total ₹15,000–50,000 on typical loans — your break-even arithmetic should clear this within 12–24 months of EMI savings.
RBI rules tilt the field your way: floating-rate home loans carry zero foreclosure or transfer penalty, so the exit cost from your current lender is nil. The most common trigger is spread drift — older borrowers sitting on repo + 3.5% while the same bank offers new customers repo + 2.0%. Before transferring, ask your current lender for a repricing letter: many will match competing offers for a flat ₹3,000–6,000 conversion fee, capturing most of the saving with none of the paperwork.
Transfers also reset eligibility for a top-up loan at home-loan rates — a popular reason to switch even when the rate gap is modest. Run the numbers both ways in this calculator: pure rate-saving versus rate-saving plus top-up against your renovation or consolidation need.
