Refinance Calculator — Monthly Savings & Break-Even Point

Compare your current mortgage against a new loan to see whether refinancing makes financial sense. Enter both sets of loan terms to get the monthly payment difference, total interest saved over the life of the loan, break-even point in months, and net savings after closing costs. The break-even period is the key number — if you plan to stay in the home longer than that, refinancing likely pays off.

Frequently Asked Questions

When does refinancing make sense?
Refinancing typically makes sense when the new rate is at least 0.5–1% lower than your current rate and you plan to stay in the home long enough to recoup the closing costs. The break-even period shown in the results is the clearest way to evaluate this.
What are typical refinance closing costs?
Refinance closing costs usually run 2–5% of the loan amount, covering origination fees, appraisal, title search, title insurance, and prepaid items. On a $300,000 loan that's $6,000–15,000. Some lenders offer "no-closing-cost" refis, but they typically roll the costs into a higher rate or the loan balance.
Does refinancing restart my 30-year clock?
It resets the amortisation schedule, which means your early payments are again weighted toward interest rather than principal. If you've been paying for 10 years on a 30-year mortgage and refinance into another 30-year loan, you now have 30 more years of payments. Refinancing into a 20- or 15-year term avoids this and often comes with a lower rate.
What is a cash-out refinance?
A cash-out refinance replaces your existing mortgage with a larger loan, and you receive the difference in cash. It's commonly used to fund home improvements, pay off high-interest debt, or invest in other property. The trade-off is a higher loan balance and monthly payment.
