How to read your result.
Break-even in months
Closing costs divided by monthly savings. If you will move or refinance again before then, the refinance loses money.
Watch the term reset
Refinancing into a new 30-year loan stretches your balance. Compare a matching term too, so savings are not just time.
Net savings over your stay
Monthly savings times the months you expect to stay, minus costs. This is the number that matters most.
No-cost options
A slightly higher rate with lender credits can remove closing costs and make break-even immediate.

For planning, 2% to 3% of your balance is typical. Your real Loan Estimate will list lender fees, title, appraisal and recording costs.
No. Taxes and insurance do not change because you refinance, so this calculator compares principal and interest only.
Check your latest mortgage statement for the maturity date, or count years since your loan started and subtract from the original term.
