Why this page exists

Refinancing only helps when the savings justify the reset. This calculator compares the existing payment against a proposed new loan so you can see the tradeoff between lower monthly cost, closing costs, and time in the property.

The refinance changes remaining lifetime cost by about $70,620 under the assumptions here.
If you expect to keep the loan longer than the break-even period, the refinance may deserve a closer look.

Closing costs, escrow changes, and lender fees vary. Use this as a first-pass estimate only.

How it works

What the calculator is doing

Estimate the current payment from the remaining balance, current rate, and remaining years on the existing loan.

Estimate the new payment using the proposed rate and term, then compare the change in monthly cost.

Use the closing cost input to calculate a simple break-even timeline and review the long-term cost difference between the two loans.

Understanding your result

Monthly savings matter, but the break-even period is often the deciding factor. If you expect to move or sell before the closing costs are recovered, the refinance may not deliver the value it first appears to promise.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Compare a shorter new term

A refinance can still be worthwhile even if the payment stays similar, especially when a shorter term cuts total interest sharply.

Stress-test closing costs

Raising the closing cost assumption shows how sensitive the break-even timeline is to lender fees and prepaid items.

Check whether the monthly savings are meaningful

A small payment drop may look attractive, but the break-even period helps you decide whether the savings are actually usable in your timeline.

FAQ

Common questions

What is a refinance break-even point?

It is the number of months it takes for monthly savings to cover the upfront closing costs of the new loan.

Should I always refinance if the rate is lower?

Not necessarily. Closing costs, the new term length, and how long you plan to keep the loan all matter.

Can a refinance lower the payment but still cost more overall?

Yes. Extending the term can reduce the monthly payment while increasing the total interest paid over time.
