Using a Home Equity Loan or HELOC to Consolidate Debt: The Honest Math
The math is compelling. The risk is real. Both matter equally.
Moving $30,000 of 22% credit card debt to 8.5% home equity saves roughly $4,050/year in interest (~$338/mo). The risk: you have converted unsecured debt (that cannot take your house) into secured debt (that can).
Interest Savings Table
| Balance | CC 18% APR | CC 22% APR | CC 26% APR | HEL 7.37% | Saving (vs 22%) |
|---|---|---|---|---|---|
| $10,000 | $1,800/yr | $2,200/yr | $2,600/yr | $740/yr | $1,460/yr |
| $25,000 | $4,500/yr | $5,500/yr | $6,500/yr | $1,840/yr | $3,660/yr |
| $50,000 | $9,000/yr | $11,000/yr | $13,000/yr | $3,690/yr | $7,310/yr |
| $75,000 | $13,500/yr | $16,500/yr | $19,500/yr | $5,530/yr | $10,970/yr |
Annual interest cost only. HEL interest at 7.37% APR, interest-only for comparison purposes.
The Foreclosure Risk -- In Plain Terms
Your credit card company cannot force you out of your home. Your home equity lender can. The unpaid credit card outcome is a charge-off, a credit score hit, and possibly a lawsuit -- serious, but recoverable. The unpaid home equity loan outcome after 120 days of missed payments in most states is foreclosure. You lose the house.
This is not a reason to never consolidate. It is a reason to consolidate only if you are confident in your income stability over the loan term, you will not re-charge the cards, and you have a 3-month emergency cash buffer to absorb a disruption.
The Behavioural Trap
Research from LendingTree and Experian consistently finds that roughly 40% of consumers who consolidate credit card debt to home equity re-accumulate credit card balances within 24 months. They end up with both the home equity loan payment and a growing card balance -- worse than before. The discipline to close or freeze the consolidated cards is not optional; it is the core risk management.
Alternatives Ranked
Cheapest if you can pay off within the intro period. Transfer fee 3-5% (one-time). No home collateral. Best for balances under $20k you can clear in 18 months.
See balance transfer optionsNo home collateral. Faster approval (1-5 days). Best for $10-30k with no desire to pledge home equity.
Compare vs personal loanFixed rate, fixed payment, home is collateral. Best for $25k+ when you can itemise and have stable income.
Variable rate adds risk to an already-leveraged situation. Works if you will aggressively snowball payments. Rate can rise.
NFCC-certified nonprofit negotiates lower rates with your creditors. No new loan, no home collateral, small monthly fee. Underused option.

12 fewer years in debt. But your home is now the collateral.
TCJA Note: Debt Consolidation Interest Is NOT Deductible
Per IRS Publication 936, home equity interest is deductible only if the loan proceeds are used to buy, build, or substantially improve the home that secures the loan. Debt consolidation -- even consolidating debt that originally was for home improvement -- does not qualify. The IRS requires tracing the proceeds to a qualifying use. See Tax Deduction Reality for the full analysis.
Pre-Consolidation Checklist
- List all current credit card balances with APR and minimum payments
- Get 2-3 HEL/HELOC quotes and compare APR, fees, and closing costs
- Calculate your monthly free cash flow after the new HEL payment
- Confirm you have a 3-month emergency cash fund (do not rely on HELOC for this)
- Plan to close or freeze the consolidated cards post-payoff (or at least stop using them)
- Check that your income is stable enough to service the loan for the full term
- Verify your credit score and DTI are within lender requirements
