Refinance: compare savings, costs, and timing

Refinance inputs to gather

• Current balance, note rate, and remaining term.
• New rate/term and any points or fees.
• Cash-to-close vs rolled-in costs.
• Time horizon before selling or refinancing again.

Refinance workflow

1. Baseline the current loan: rate, balance, term, and remaining months.
2. Model the new offer: rate, term, and estimated closing costs.
3. Estimate break-even: divide total costs by monthly savings.
4. Check time horizon: if you may move or refinance again, compare savings over that window.
5. Validate the fee list: make sure lender credits or points are included consistently.

What typically drives the decision

• Rate difference and remaining balance.
• Total cash to close (fees, points, prepaid items).
• Whether the new term resets the clock.
• Expected time in the home.

Refinance vs other options

• Extra principal payments can reduce interest without new fees.
• Recast options may lower the payment without changing the rate.
• Rate buydown points can be compared to a no-point option with the same term.

Time horizon check

Break-even only matters if you keep the loan long enough. If a move or another refinance is likely, compare total savings over that shorter window instead of the full term.

Term reset watchout

A lower rate can still increase total interest if you restart a 30-year term. Compare remaining term interest on your current loan to the new term interest so you see the full cost.

Cash-to-close vs rolling in costs

The same offer can look different depending on how costs are handled. Paying costs upfront lowers the loan balance, while rolling them in increases interest over time. Compare both ways so you can see the real trade-off.

Rate lock and credits

A lender credit can reduce cash-to-close but usually comes with a higher rate. Compare a credit option to a no-credit option over your expected time horizon to see which costs less.

Break-even example

If closing costs are $4,000 and the monthly savings are $160, break-even is 25 months. If you might move in 18 months, the math likely does not work unless there are other benefits.

Offer comparison checklist

• Same remaining term vs new term (avoid comparing 30 years to 22 years).
• Same fee list: points, lender credits, and third-party fees.
• Same cash-to-close treatment (paid upfront vs rolled in).
• Same start date and posting assumptions for payoff math.

Common pitfalls

• Comparing a 30-year new loan to a remaining 22-year term without adjusting for total interest.
• Ignoring lender credits or points that change the cash-to-close.
• Focusing only on the monthly payment and missing total cost over time.

Statement check

• Use your current statement balance and remaining term in months.
• Confirm the note rate, not the APR, when comparing payments.
• Use the Loan Estimate fee list so costs are itemized.

Inputs to gather first

• Current balance, rate, and remaining term from your latest statement.
• Quoted rate, term, and any points or lender credits for the new offer.
• Estimated closing costs itemized by lender and third-party fees.
• Your expected time in the home or time until the next refinance.

Decision checklist

• Do you expect to keep the loan long enough to break even?
• Are fees paid upfront or rolled into the loan?
• Does the new term extend the payoff horizon?
• Have you compared refinance to extra principal payments?
