How much lower does the rate need to be to make refinancing worth it?

The old rule of thumb was a full percentage point, but the honest answer is whatever clears your break-even point comfortably. Divide your total closing costs by the monthly saving to see how many months it takes to recoup the fees. If you will keep the loan well past that point — often 2 to 4 years — even a 0.5-0.75% drop can pay off. If you might sell or refinance again sooner, it likely won't.

Does refinancing restart my loan term?

Usually yes. Refinancing a 30-year mortgage you have paid for six years into a fresh 30-year loan means paying interest for 36 years total, which can cost more overall even at a lower rate. To avoid that, refinance into a shorter term — say a 15- or 20-year loan — or keep making payments as if the term never reset.

Is a cash-out refinance a good idea?

It can be if the cash funds something that builds value, like home improvements or paying off high-interest debt, and your new rate is still low. The risk is that you are converting unsecured or short-term debt into debt secured by your home, stretched over decades. If you can't repay it, the house is on the line, so treat cash-out as borrowing against your home, not free money.

What does refinancing actually cost?

Closing costs typically run 2-6% of the loan balance and cover appraisal, origination, title and other fees. Some lenders offer a no-closing-cost refinance, but they recover the fees through a higher rate or a bigger balance, so you pay either way. Always compare the total cost and the new rate across at least three lenders before committing.

Should I refinance my mortgage?

Should I refinance my mortgage to change my rate or term?

Refinancing can shrink your monthly payment, shorten your loan, or free up cash from your home's equity — but it resets the clock and comes with closing costs that take years to earn back. Whether it pays off depends on how far rates have moved and how long you will keep the loan.

Short answer

Refinance if the new rate is low enough that your monthly savings recoup the closing costs well before you plan to sell or move — commonly a 0.5-1% rate drop with a break-even under 2-4 years. Be cautious if refinancing stretches a loan you have already paid down for years back into a fresh 30-year term, since that can raise your total interest even at a lower rate. The deciding numbers are your break-even point and how long you will keep the loan, not the headline rate alone.

Check before you decide

Calculate your break-even point: divide total closing costs by the monthly saving to see how many months to recoup the fees.
Confirm you will keep the loan and the home well past that break-even point.
Get quotes from at least three lenders and compare the full closing costs, not just the advertised rate.
Decide the new term deliberately — a shorter term or extra payments avoids paying decades more interest.
Check your current credit score and income, since they set the rate you actually qualify for.
If considering cash-out, confirm the money funds something worth borrowing against your home for.
