Refinancing and home equity
Is refinancing worth it?
Written for Shawn Way MortgageUpdated Sources checked
The short answer
Refinancing is worth it when the benefit over the time you expect to keep the new loan is larger than its costs. Compare the monthly savings, the closing costs, how much you'll still owe after that period, and whether the term starts over. A lower payment alone doesn't prove you save money: stretching a loan back to 30 years can cost more in total interest.

What should you compare before refinancing?
Put keeping your current loan on the page as an option. Then compare each new loan over the same period, perhaps three, five or ten years. Include fees paid in cash and any costs added to the balance. Separate escrow deposits and prepaid items from the cost of the loan itself so cash needed at closing isn't confused with what the refinance costs.
A Loan Estimate shows the loan amount, payment, closing costs and lender credits. Ask which charges change and why.
What happens when the term starts over?
In the example above, the new 30-year loan lowers the payment by about $376 a month. But after five years its balance is about $12,357 higher than if you'd kept the current loan, and if both run to payoff, it costs about $77,924 more in interest and fees. The 25-year refinance gives less payment relief but keeps the payoff date and saves money over every period shown.
Is the break-even month enough?
$6,000 ÷ $376 ≈ 16 months
That simple break-even shows how quickly the payment savings repay the cash cost. It misses the different balances. If your goal is lower total cost, compare interest and fees over your likely holding period too. If your goal is payment relief, be clear about what that relief costs.
A shorter-term refinance can have a higher payment and still save a lot of interest; a monthly-savings break-even can't show that benefit.
When does refinancing usually make sense?
- Rates have fallen enough that the savings repay costs well within the time you'll keep the loan.
- You want to move from an adjustable rate to a fixed one, or shorten the term.
- You want to remove FHA mortgage insurance by moving to a conventional loan once you have enough equity.
- You need cash and a cash-out refinance compares well with a HELOC or home equity loan.
What should you bring to the conversation?
- Your current balance, rate, payment and remaining term.
- Any refinance quote you have, including points, lender credits and every closing cost.
- When you might move or pay off the loan, and the cash you're comfortable spending.
- Whether your goal is lower cost, payment relief, faster payoff or cash out.
Ask for the current loan and each replacement on the same timeline. A later refinance is never guaranteed, so today's decision should work even if rates don't cooperate.
Worked example: the payment drops, the cost rises
The new 30-year loan saves $376 a month, which is $22,560 over five years. Yet five years in, you owe $12,357 more than you would have on the current loan, and the payoff date has moved five years later. Lower payment, higher lifetime cost.
The new 25-year loan saves about $156 a month and, after five years, leaves you owing about $3,075 less than the current loan, while finishing on the same date.

Questions people ask
How much do rates need to drop to refinance?
There's no fixed rule. What matters is whether the savings repay the closing costs well within the time you'll keep the loan, and what happens to the term and balance.
How much does it cost to refinance?
Refinance closing costs vary by loan size, state and lender. Your Loan Estimate itemizes them; compare at least two estimates for the same loan.
Does refinancing restart my loan?
Usually. Most refinances start a new term. You can often choose a shorter term, such as 25, 20 or 15 years, to avoid extending your payoff date.
Can I refinance to get rid of mortgage insurance?
Often. Moving from an FHA loan to a conventional loan with enough equity can remove monthly mortgage insurance, but compare the new rate and costs.
