Key Refinance Considerations

Break-Even Point

This is the number of months it takes for your monthly savings to equal your closing costs. If you plan to stay in your home longer than the break-even period, refinancing likely makes sense.

Total Interest Savings

While monthly savings are important, also consider total interest paid over the life of the loan. Sometimes a lower monthly payment extends the loan term, increasing total interest.

Loan Term Impact

Extending your loan term lowers monthly payments but increases total interest paid. Shortening your term increases monthly payments but reduces total interest significantly.

Pro Tip: As a general rule, consider refinancing if you can lower your interest rate by at least 0.75% and plan to stay in your home long enough to reach the break-even point.
