The short answer
Refinancing can be worth it when the benefit over the time you expect to keep the new loan exceeds its costs. Compare monthly savings, upfront fees, the remaining balance and the repayment term. A lower payment alone does not establish savings.
What should you compare before refinancing?
Put keeping the current loan on the page as an option. Then compare a new loan over the same period—perhaps three, five or ten years. Include fees paid in cash and any costs added to the balance. Separately identify escrow deposits and prepaid expenses so the comparison does not confuse cash needed at closing with the cost of obtaining the loan.
A Loan Estimate helps identify the loan amount, payment, closing costs and lender credits. Ask which charges are changing and why. The CFPB’s refinance guide also explains how extending the term can lower the payment while increasing total interest.
What happens when the term starts over?
Suppose you owe $500,000 at 6.75%, with 25 years left. Compare two hypothetical 6.25% replacements: a new 30-year loan and a new 25-year loan. Each refinance costs $6,000 paid in cash; none of those costs is financed.
| Compare | Keep current | New 30 years | New 25 years |
|---|---|---|---|
| Monthly payment | $3,455 | $3,079 | $3,298 |
| Refinance costs | $0 | $6,000 | $6,000 |
| Balance after five years | $454,329 | $466,686 | $451,255 |
| Five-year interest + refinance costs | $161,603 | $157,401 | $155,155 |
| Interest + costs over remaining loan life | $536,367 | $614,291 | $495,504 |
The new 30-year loan lowers the payment by about $376. But after five years its balance is about $12,357 higher than keeping the current loan. If both run to their scheduled payoff, that replacement costs about $77,924 more in interest and fees.
The 25-year replacement produces less payment relief but preserves the payoff timeline. This example illustrates why the choice depends on both monthly needs and long-term cost.
Original educational calculation using monthly amortization and no extra payments. These rates are assumptions, not available quotes. Excludes taxes, insurance, mortgage insurance, tax effects and returns on cash. Actual payoff figures and payment rounding vary.
Is the break-even month enough?
Simple payment break-even for the 30-year replacement.
That calculation measures how quickly payment reductions recover the cash fee. It misses the different remaining balances. If the goal is reducing financing cost, compare interest and fees over your likely holding period as well. If the goal is immediate payment relief, discuss the price of obtaining it.
A shorter-term loan can have a higher payment and still reduce interest. In that case, a monthly-savings break-even calculation will not describe the benefit.
What should you bring to Shawn?
- Your current balance, rate, payment and remaining term.
- The new quote, including points, lender credits and every closing cost.
- Your likely move or payoff date and the cash you can comfortably spend.
- Whether the goal is lower cost, payment relief, faster payoff or access to equity.
Ask for the current loan and proposed replacements on the same timeline. A later refinance is uncertain; today’s decision should also work if future rates do not cooperate.
