Result guide
- Monthly savings can be positive even when lifetime savings are weak if the new loan term is extended significantly.
- Break-even point is only shown when the refinanced payment is actually lower than the current payment.
- This page estimates payment tradeoffs only and does not include escrow, taxes, or cash-out scenarios.
Why this page matters
A refinance page matters because a lower rate does not automatically mean a better deal. Closing costs and the new loan term can materially change whether the refinance actually improves the situation.
The strongest quick check is break-even timing. It tells a homeowner how long they need to keep the new loan before the upfront refinance cost has been recovered through lower monthly payments.
Frequently asked questions
Why can refinancing lower the monthly payment but still reduce lifetime savings?
Because stretching the loan into a longer term can lower the monthly payment while increasing how long interest is paid overall.
What does the break-even point mean here?
It is the time needed for lower monthly payments to recover the refinance closing costs.
Does this include cash-out refinance effects?
No. This version compares rate, term, and closing costs on the same balance rather than modeling a cash-out scenario.
