A smaller payment is one part of the story.

Name the reason for the change.

Refinancing means replacing your current mortgage with a new one. You might want a lower payment, to pay off the loan sooner or to borrow some of your home’s equity. Each goal calls for a different comparison. The CFPB’s refinance worksheet can help.

Tell us what you want to change and what you want to keep. For example: “I want a smaller payment, but I do not want to start another 30 years of payments.”

Use break-even as a first pass.

Break-even is how long it takes for monthly savings to cover the cost of refinancing. For a simple example, $4,800 in costs divided by $200 in monthly savings equals 24 months. These are made-up numbers to show the math, not a quote.

Ask which fees belong in that calculation. Money set aside for future taxes and insurance is different from a loan fee. If fees are added to your new loan, you still pay them and may pay interest on them.

This shortcut is only a first check. It does not compare how much you will still owe or every long-term cost. Ask to see those numbers too.

Check the clock and the balance.

A lower payment may come from spreading the debt over more years. Ask how much of the reduction comes from a lower rate and how much comes from a longer repayment period. The CFPB’s mortgage terms explain the basics.

Pick a date that fits your plans, such as when you expect to move. Compare what you would pay by then and what you would still owe on each loan. Include the costs of making the change.

Also look at what happens if you move sooner. You may not keep the loan long enough for the monthly savings to cover its fees.

Translate “no closing cost” into actual terms.

“No closing cost” usually means the costs are covered through a higher interest rate or added to your loan balance. They have not disappeared. Ask to compare those choices with paying the costs upfront. The CFPB explains no-closing-cost refinancing.

Bring both loans to the conversation.

• Current balance, payment, interest rate and remaining term.
• Proposed balance, term, payment and itemized refinance costs.
• How costs will be paid and which payment components are compared.
• Your likely time in the loan, with an earlier-exit scenario.
• What you will have paid and what you will still owe at the same date.

A clear review may support refinancing, waiting or keeping your existing mortgage. The useful outcome is a decision you understand, including the assumptions that could make you revisit it.
