Should I Refinance My Mortgage to Pay Off Debt?

Refinancing your mortgage to pay off debt makes sense when your new mortgage rate is meaningfully lower than your current rate, you have enough home equity to take cash out, and you can recover the closing costs through interest savings within a few years. It does not make sense if your current mortgage rate is already lower than today's rates, if you plan to move before reaching the break-even point, or if you have not addressed the spending habits that created the original debt.

When Refinancing to Pay Off Debt Makes Sense

A cash-out refinance replaces your existing mortgage with a new, larger loan. You receive the difference as cash and use it to pay off high-interest debt. According to Federal Reserve data, the average credit card interest rate was approximately 21% in late 2024. Mortgage rates, while they fluctuate, are typically far lower. That gap is where the savings come from.

Refinancing makes sense when all of the following are true:

• Your new mortgage rate is lower than your current one. If you are moving from a 4% mortgage to a 7% mortgage just to access cash, the math rarely works. The interest rate on the consolidated debt needs to drop enough to offset any increase in your mortgage rate.
• You have at least 20% equity in your home after the new loan. Most lenders require you to maintain a meaningful equity cushion. According to Freddie Mac's lending guidelines, cash-out refinances typically require at least 20% equity remaining after the new loan.
• Your closing costs are recoverable. Closing costs typically run 2 to 5 percent of the loan amount. If you pay $6,000 in closing costs to save $200 per month on interest, it takes 30 months to break even. If you plan to sell before that, you lose money.
• You have a plan to avoid re-accumulating credit card debt. The Consumer Financial Protection Bureau (CFPB) has noted that many homeowners who consolidate credit card debt into a mortgage end up carrying new card balances within two years. Without a behavioral change, you end up with both a larger mortgage and new credit card debt.

When It Probably Does Not Make Sense

• Your current mortgage rate is lower than what you could get today. Giving up a 3.5% rate to consolidate debt at 7% usually costs more than it saves, even accounting for the credit card rate reduction.
• You plan to move within 2 to 3 years. Closing costs take time to recover. If you sell too soon, you eat the costs without realizing the savings.
• You have not changed the spending habits that created the debt. If you pay off the cards and then run them back up, you are worse off than before.
• Your home equity is thin. With less than 20% equity, your options narrow and rates get worse. You may also need to pay for private mortgage insurance (PMI).

How to Calculate the Break-Even

The break-even point is how long it takes for your monthly interest savings to cover your closing costs.

1. Add up your closing costs. Get a Loan Estimate from your lender. It will list all costs.
2. Calculate your monthly interest savings. Compare what you pay in interest on your credit cards each month versus what you would pay on the new mortgage for the same balance.
3. Divide closing costs by monthly savings. That gives you the number of months to break even.

For example: if your closing costs are $5,000 and you save $300 per month in interest, your break-even is about 17 months. If you plan to stay in the home longer than that, the refinance starts saving you money.

Cash-Out Refinance vs Rate-and-Term Refinance

A cash-out refinance gives you money to pay off debt. A rate-and-term refinance only changes your rate and term, with no cash back. If your goal is debt consolidation, you need the cash-out version.

The tradeoff: a cash-out refinance typically has a slightly higher rate than a rate-and-term refinance, and you are increasing your mortgage balance. Use our debt consolidation calculator at /calculators to model the numbers with your own balances and rates.

Alternatives to Consider

Before refinancing, compare against:

• A home equity loan or HELOC at /home-equity-debt-consolidation — these let you borrow against your equity without touching your first mortgage. If your current mortgage rate is low, this preserves it.
• A personal loan: unsecured, so no risk to your home, but rates are higher than home equity products.
• A balance transfer credit card: if you can pay off the balance during the 0% introductory period, this can be the cheapest option for smaller debt amounts.
• A debt management plan at /financial-options through a nonprofit credit counseling agency: they negotiate lower rates with your creditors without requiring a loan.

The Bottom Line

Refinancing your mortgage to pay off debt is a math decision, not an emotional one. If the numbers work, the rate gap is large enough, and you have addressed the root cause of the debt, it can save thousands. If any of those conditions are not met, the alternatives above may serve you better.
