Key takeaways
What to know before you compare
- Define the goal before comparing rates or payments.
- Break-even months roughly equal eligible upfront costs divided by reliable monthly savings.
- A lower payment can cost more if the new loan lasts much longer.
- Compare total costs over the period you realistically expect to keep the new loan.
Which goals can a refinance address?
A borrower may seek a lower rate, a different term, a more stable rate structure, removal of a co-borrower where permitted, or access to equity. Each goal uses a different comparison. A lower payment is not enough if it comes mainly from extending repayment.
Cash-out refinancing also increases the amount secured by the home. Compare the new mortgage with alternatives and consider the risk of converting other debt into debt secured by the property.
How do closing costs affect break-even?
List lender charges, points, third-party services, and other eligible costs, then divide the upfront amount by reliable monthly savings for a rough break-even estimate. Credits or financed costs are not free; they may raise the rate or balance.
Compare costs over a short, likely, and long holding period. If you sell or refinance again before break-even, the expected savings may not materialize.
How should the old and new loans be compared?
Record the current balance, remaining term, rate, payment, and expected future interest. For the proposed loan, record the new balance, term, rate, APR, closing costs, points or credits, payment, and total interest over the expected holding period.
Ask whether taxes, insurance, mortgage insurance, or escrow changes explain part of the payment difference. Review the Loan Estimate and final Closing Disclosure carefully.
Frequently asked questions
Is a no-closing-cost refinance free?
No. Costs may be covered through a higher rate, a larger balance, or another pricing tradeoff.
Should I refinance whenever the rate is lower?
Not automatically. Closing costs, the new term, the amount borrowed, and how long you keep the loan determine the result.
Can a lower refinance payment increase total cost?
Yes. Extending the term can reduce the payment while creating more years of interest.
