Debt Consolidation Calculator

Debt consolidation is the process of combining multiple debts — such as credit cards, auto loans, personal loans, and medical bills — into a single, more manageable payment. Rather than juggling several due dates, varying interest rates, and multiple creditors, you replace them with one loan at (ideally) a lower overall interest rate.

For homeowners, one of the most powerful ways to consolidate debt is by leveraging home equity. Because your home serves as collateral, lenders can offer significantly lower interest rates compared to unsecured debts like credit cards, which routinely charge 18–29% APR. A home equity–based consolidation loan might carry rates between 6–9%, potentially saving thousands in interest over the life of your debts.

The concept is straightforward: you borrow against the equity you've built in your home — the difference between your home's current market value and what you still owe on your mortgage — and use those funds to pay off your higher-interest debts. You're left with a single monthly payment at a lower rate, often with the added benefit of tax-deductible interest (consult your tax advisor for eligibility).

The process begins with determining how much equity you have available. Most lenders allow you to borrow up to 80% of your home's appraised value minus your existing mortgage balance, though some programs extend to 85% or even 90% for well-qualified borrowers.

Step 1: Calculate your available equity. If your home is worth $500,000 and you owe $350,000 on your mortgage, you have $150,000 in equity. At an 80% loan-to-value (LTV) limit, the maximum you could borrow is $400,000 minus your existing $350,000 balance = $50,000 available for consolidation.

Step 2: Tally your debts. List every debt you want to consolidate — credit cards, auto loans, personal loans, medical bills, and any other balances. Include each balance, interest rate, and minimum monthly payment. This gives you a clear picture of your total debt burden and the "blended" interest rate you're currently paying.

Step 3: Choose your loan product. Homeowners typically have three options for equity-based consolidation:

• Cash-Out Refinance: Replace your existing mortgage with a new, larger loan and receive the difference in cash. This works best when you can also lower your mortgage rate or when you have substantial equity and debt to consolidate.
• Home Equity Loan (HEL): A second mortgage with a fixed rate and fixed payments. You receive a lump sum at closing and repay it over a set term, typically 5–30 years. Ideal when you want predictable payments and your first mortgage already has a favorable rate.
• Home Equity Line of Credit (HELOC): A revolving credit line that works like a credit card but at much lower interest rates. Draw funds as needed during the draw period (usually 5–10 years), then repay during the repayment period. Best for ongoing or variable expenses, though rates are typically adjustable.

Step 4: Apply, close, and pay off debts. Once approved, you'll go through a closing process similar to your original mortgage. After closing, use the funds to pay off your consolidated debts immediately. You now have one payment to manage instead of many.

Debt consolidation using home equity isn't always the right answer. It makes the most financial sense when specific conditions are met:

• Your debt interest rates are significantly higher than available equity rates. If you're paying 15–25% on credit cards but can get a home equity product at 6–8%, the interest savings are substantial. As a rule of thumb, a spread of 5%+ makes consolidation worth exploring.
• You have sufficient equity. You need enough home equity to cover your debts while maintaining a combined LTV at or below 80%. Higher LTV ratios may be possible but often come with higher rates or additional fees.
• You've addressed the underlying spending patterns. Consolidation frees up credit card limits, which can be dangerous if you resume charging. It works best when paired with a budget and spending discipline.
• You plan to stay in your home. Since you're tapping equity, you'll want to give yourself time to rebuild it. If you're planning to sell within a year or two, the closing costs may outweigh the savings.

While consolidation can be a powerful tool, it's important to understand the risks involved:

You're converting unsecured debt into secured debt. Credit card debt, while expensive, is unsecured — the worst outcome of non-payment is damage to your credit score and potential collections. When you consolidate that into a home equity loan, your home becomes the collateral. If you can't make the payments, foreclosure becomes a possibility. This is the single most important risk to weigh.

Longer terms can mean more total interest. A lower monthly payment feels like a win, but stretching a $25,000 debt from 5 years to 30 years — even at a lower rate — can actually increase the total interest you pay. Always compare total cost, not just the monthly payment. Use our calculator above to see both figures side by side.

Closing costs eat into savings. Cash-out refinances and home equity loans come with appraisal fees, origination fees, title insurance, and other closing costs, typically ranging from 2–5% of the loan amount. Factor these into your break-even analysis. If closing costs are $5,000 but you're only saving $3,000 in interest, the math doesn't work.

Re-accumulating debt is a real danger. Once credit card balances are zeroed out, the temptation to use them again is strong. Financial advisors often recommend closing or freezing cards after consolidation, or at minimum creating a strict budget to avoid adding new debt on top of the consolidation loan.

Each product has distinct advantages depending on your situation:

A cash-out refinance replaces your entire first mortgage. This simplifies your payments to one but means you'll restart your mortgage clock — something to consider if you've already paid down significant principal. A HELOC offers maximum flexibility but carries rate risk. A home equity loan splits the difference with fixed-rate predictability and lower closing costs than a full refi.
