Should You Refinance a $350,000 Mortgage?
Dropping from 6.5% to 5.5% on $350,000 cuts the payment by $376 a month and breaks even in 8 months.
On a $350,000 balance with 25 years left at 6.5%, you are paying $2,363 a month. Refinancing into a 30-year loan at 5.5% brings that to $1,987 — a saving of $376 every month. Closing costs of $3,000 mean you are ahead after 8 months, so the move pays off if you stay in the house longer than that.
Watch the lifetime number as well as the monthly one. Restarting the clock at 30 years spreads the balance over longer, so total interest goes from $358,968 to $365,414. The calculator below is set to this scenario — change the new term to 25 years to keep your original payoff date, or enter the actual rate you were quoted.

Frequently Asked Questions
- Going from 6.5% to 5.5% takes the payment from $2,363 to $1,987 — $376 a month, or $4,512 a year. Against $3,000 of closing costs you break even in 8 months. A smaller rate drop still helps: at 6% the saving is $265 a month.
- On a balance this size, usually yes. One point off 6.5% on $350,000 is worth about $376 a month, which clears typical closing costs within a couple of years. The old "you need 2%" rule dates from when balances were smaller — what actually matters is your break-even point against how long you plan to stay.
- At $3,000 in costs and $376 a month saved, 8 months. Sell or refinance again before then and the move cost you money. If you are unsure how long you will stay, ask your lender about a no-closing-cost refinance — the rate is higher but there is nothing to recoup.
- Only if you choose a 30-year term. Refinancing $350,000 back to 30 years lowers the payment most but raises total interest to $365,414 versus $358,968 on your current path. Refinancing into a 25-year term instead keeps your original payoff date: the payment becomes $2,149 and lifetime interest drops to $294,792.
