If you are paying 15% or more on cards while your home has equity, a refinance could help, but only if the math passes these tests.
Here is a simple way to decide if a refinance to pay off high-interest debt is smart for you.
1 - Know your blended interest rate. Add up all balances and their rates to see your true average cost of debt.
If cards are at 20% and a personal loan is at 12%, your blended rate may be far higher than your mortgage.
2 - Calculate break-even. Divide total refi costs by the projected monthly savings to see how many months it takes to recover the costs.
If you will not stay past that point, the math fails.
3 - Match the term to the goal. Shorter terms raise payment but lower total interest.
Longer terms lower payment but can increase lifetime interest. Pick the term that fits your season of life.
4 - Protect cash flow and habits. Keep an emergency fund and set up autopay to avoid re-running balances.
Debt consolidation only works if the spending problem is solved.
5 - Know the tax angle. Interest on cash-out used to pay consumer debt is generally not tax-deductible.
Talk with a CPA before you count on deductions. Rules vary by state and situation.
Not everyone should refinance. But if the boxes above check out, a refi can simplify bills, improve cash flow, and lower total cost over time.
