How to Refinance a Mortgage in 5 Steps: Costs and Break-Even
How to refinance a mortgage in 5 steps: common goals, the Loan Estimate, closing costs, and a worked break-even example with stated assumptions.
Last checked
Refinancing means replacing your current mortgage with a new loan, usually to pursue a lower interest rate, a shorter term, or more stable payments. The tradeoff is real: a refinance can lower your monthly payment, but closing costs mean the savings take time to repay themselves. This guide walks through five steps so you can compare offers and calculate your own break-even point before you apply.
The Consumer Financial Protection Bureau (CFPB) covers the reasons to refinance, the costs, and the Loan Estimate. The cost categories and the break-even formula below are general guidance and simple arithmetic, so confirm them on your own Loan Estimate.
In this guide: - What refinancing a mortgage means - Common reasons homeowners consider it - The 5 steps, in order - Closing costs to expect - The break-even calculation, with a worked example
What refinancing a mortgage means
A refinance pays off your existing mortgage and replaces it with a new one. The new loan has its own interest rate, term, and monthly payment, and you go through an application and closing process again. According to the CFPB, you could go through many of the same steps and pay many of the same costs as you did with your original mortgage.
Because the loan is new, its terms are set from current market conditions and your current financial picture, not from the conditions of your original purchase. That is why refinancing is generally considered when rates, home value, or your plans have changed enough to make the switch worth evaluating.
At closing, the new loan pays off the old balance in full, and your future payments go to the new lender or servicer. Because the transaction replaces one debt with another rather than adding new debt, the key comparison is the total cost of the new loan against the remaining cost of the old one, including every fee you pay to make the switch.
Common reasons to consider refinancing
The CFPB notes that homeowners often refinance to lower their mortgage costs, to shorten the loan, or to move from an adjustable-rate mortgage to a fixed rate for more certainty. Each goal carries a tradeoff worth checking before you commit.
| Goal | What changes | Tradeoff to check |
|---|---|---|
| Lower rate, same term | Monthly payment falls | Closing costs still apply |
| Shorter term | Payoff date moves closer | Monthly payment may rise |
| Adjustable to fixed rate | Rate stops adjusting | New fixed rate may sit above the current adjustable rate |
Match the refinance type to your goal first, then run the break-even math later in this guide. A goal without the math is only half a decision.
Refinance in 5 steps
- Set your goal and timeline. Decide whether you want a lower payment, a shorter term, or rate stability, and estimate how long you plan to keep the loan. The timeline matters because closing costs are recovered month by month.
- Gather your numbers. Note your current interest rate, remaining balance, monthly principal-and-interest payment, and how many years are left. These are the inputs every comparison will need.
- Shop and compare Loan Estimates. When you request a refinance, you receive a Loan Estimate that describes the loan's features, including any prepayment penalty and the total dollar cost of the loan. Apply with more than one lender and compare the forms line by line, not just the advertised rate. Consider checking with a housing counselor or financial professional if the forms are hard to read.
- Choose a lender and ask about a rate lock. Consider asking how long a rate lock lasts and what it costs, then complete the appraisal and document review the lender requests.
- Review the Closing Disclosure and close. The CFPB advises checking that the closing costs, loan terms, monthly payment, and cash to close match your most recent Loan Estimate, and asking your lender to explain any change.
Closing costs to expect
A refinance is a new mortgage, so the CFPB notes you could pay many of the same costs as with your original loan. In general, those include lender charges, appraisal and credit report fees, title and settlement services, and recording charges, and some loans add discount points. The exact total varies with your loan size, property, and lender, so treat any single figure as illustrative until you see your own Loan Estimate.
One distinction keeps the math honest. Prepaid items such as property taxes, insurance premiums, and the initial escrow deposit generally affect the cash you need at closing but are separate from the lender costs of the refinance itself. Ask your lender which lines on the Loan Estimate fall into each group, and separate the two before you calculate break-even.
The break-even calculation
The break-even point is the month when your accumulated monthly savings equal the closing costs you paid. After that month, the refinance starts saving you money. Before it, you are still repaying the cost of the transaction.
Worked example with stated assumptions (hypothetical numbers): assume total refinance closing costs of 6,000 dollars (lender and third-party charges only; prepaid taxes, insurance, and escrow deposits excluded), monthly principal-and-interest savings of 200 dollars (escrow unchanged), and savings that stay constant each month.
Break-even in months = 6,000 dollars / 200 dollars per month = 30 months.
If you plan to sell the home or refinance again before month 30, the transaction may not recover its costs. The CFPB makes the same point: if you plan to move soon, you might not have time to recoup the cost of refinancing. Also compare total interest, not just the monthly payment. Making lower payments for more years could mean a higher total cost, so extending the term back to 30 years can lower the payment while raising the total interest paid over the life of the loan.
