Is refinancing your mortgage worth it in 2026?

Refinancing replaces your current mortgage with a new one, ideally at a lower rate or better terms. Done at the right time it saves real money; done at the wrong time it just hands the bank thousands in closing costs. The whole decision comes down to one number: the break-even point.

What refinancing actually does

A refinance pays off your existing loan with a new one. People do it to:

• Lower the interest rate and monthly payment
• Shorten the term (e.g., 30 years to 15) to pay less interest overall
• Switch loan types (adjustable to fixed)
• Tap equity with a cash-out refinance

The most common reason is a lower rate, but a lower rate doesn't automatically mean it's worth it.

The break-even point is everything

Refinancing isn't free. Closing costs typically run 2-5% of the loan amount, on a $300,000 loan that's $6,000-$15,000. To know if it's worth it, divide the cost by your monthly saving:

Break-even months = closing costs ÷ monthly savings

If refinancing costs $6,000 and saves $200/month, you break even in 30 months. Stay in the home longer than that and you profit; sell or move sooner and you lose money. Model your current and proposed payments side by side with the Mortgage Calculator to find the monthly saving.

When refinancing makes sense

• The new rate is meaningfully lower than your current one (even ~0.5-1% can be worth it on a large balance).
• You'll stay in the home well past the break-even point.
• You're shortening the term and can afford the higher payment for less total interest.
• You need to switch from an adjustable rate to a fixed one for stability.

When to think twice

• You plan to move before breaking even.
• You'd restart a 30-year clock late into your current loan, paying more interest overall despite a lower rate.
• Your credit has slipped, so the new rate isn't actually better.
• The closing costs are rolled into the loan, quietly enlarging your balance.

Don't just chase the monthly payment

A lower monthly payment can hide a worse deal. Resetting a loan you're 8 years into back to 30 years lowers the payment but can increase total interest paid. Always compare the lifetime interest, not just the monthly number, the Mortgage Calculator shows both.

The bottom line

Refinancing is worth it when your monthly savings pay back the closing costs well before you'd sell or move, and when the lifetime interest actually drops. Run your current loan and the proposed one through the Mortgage Calculator, find your break-even month, and let that number, not the advertised rate, make the call.
