Start with the number that makes people consider this

According to the Federal Reserve's G.19 consumer credit release, the average APR on credit card accounts assessed interest reached 22.15% in Q2 2026, up from 21.52% the prior quarter. Across all accounts, the average sat at 20.94%.

At 22%, a $30,000 balance accrues roughly $6,600 a year in interest before a dollar touches principal. Minimum payments are structured so that a large share of each payment services interest, which is why balances at these rates can persist for years while feeling like they're being paid down.

Against that, home equity borrowing — secured by real property and priced off the prime rate, 6.75% as of July 2026 — is dramatically cheaper. The arithmetic is not subtle, and it is why debt consolidation is one of the most common reasons homeowners inquire about a HELOC.

But the arithmetic is not the whole decision, and I would be doing you a disservice to present it as though it were.

What you are actually doing

This is the part that gets glossed over in most content on this topic.

You are not "lowering the interest rate on your debt." You are converting unsecured debt into secured debt.

Credit card debt is unsecured. If you cannot pay it, the consequences are serious — collections, credit damage, potentially a judgment. They do not include losing your house, because no lien attaches to your home.

A HELOC is secured by your home. That security is exactly why the rate is lower — the lender's risk is reduced because there is collateral. When you use a HELOC to retire credit card balances, you are moving that debt onto the collateral.

For a household with stable income and a genuine plan to repay, this is often a sound, money-saving decision. For a household whose debt arose from income instability, it converts a survivable problem into one with a much harder floor.

The rate comparison is real. So is this. Both belong in the decision.

The pitfall that undoes most consolidations

Here is the failure pattern, and it is common enough that any honest lender will warn you about it:

  1. You draw on the HELOC and pay the cards to zero.
  2. The monthly payment drops substantially. Cash flow improves. This feels like success.
  3. The cards now have zero balances and full available limits.
  4. Over the following year or two, life happens and the balances creep back.
  5. You now carry the credit card debt and the HELOC secured by your home.

The consolidation did not reduce debt. It relocated debt and reopened capacity, and the capacity got used.

This is not a character failing — it is a predictable consequence of removing a constraint without addressing what created the balances. If the underlying cause was a genuinely one-time event (a medical episode, a period of unemployment now ended), consolidation addresses a problem that has already stopped. If the cause is that monthly outflow exceeds monthly income, consolidation buys time without fixing anything, at the cost of putting your home behind the debt.

Ask yourself plainly which situation you are in. The answer should change what you do.

Structural differences worth understanding

Amortization. Credit cards are revolving with minimum payments that never fully retire the balance on a defined schedule. A HELOC has a draw period followed by a repayment period. During the draw period, payments may be interest-only — which keeps payments low but does not reduce principal. If you consolidate and then make only interest-only payments for the entire draw period, you arrive at the repayment period owing the same amount, now with a compressed schedule and a materially higher payment. Know your draw period end date before you sign.

Rate structure. Card rates are variable and can be repriced. HELOC rates are typically variable too, tied to prime. You are not trading variable for fixed — you are trading a higher variable rate for a lower one. If rates rise, your HELOC payment rises with them.

Tax treatment. Interest on funds used for debt consolidation is not deductible. Only proceeds used to buy, build, or substantially improve the home securing the loan qualify under IRS Publication 936. Do not let anyone include a tax benefit in the pitch for a consolidation. There isn't one. See Is HELOC Interest Tax Deductible?.

A framework for deciding

Consolidation tends to make sense when:

  • The debt came from a discrete event that has ended
  • Your income is stable and documented
  • The total is meaningfully payable within the draw period
  • You have a concrete plan for the cards — closing them, reducing limits, or removing them from daily use
  • You have run the amortizing payment, not just the interest-only payment, and it fits

Be far more cautious when:

  • Balances grew gradually from ongoing shortfall rather than a one-time event
  • Income is variable, uncertain, or recently reduced
  • You have consolidated before and the balances returned
  • You would need the full draw period at interest-only just to stay current
  • Combined loan-to-value would leave you with thin equity if values softened

If you proceed, do these four things

  1. Run the fully amortizing payment, not the interest-only minimum. That is the payment that actually retires the debt. If it doesn't fit your budget, the plan doesn't work — you've just moved the problem.
  2. Deal with the cards. Close them, reduce the limits, or remove them from your wallet and your saved payment methods. Leaving full limits available is the mechanism by which this fails.
  3. Set a payoff date and work backward. A balance without a deadline drifts. Pick the date, compute the payment, automate it.
  4. Know exactly when your draw period ends and what the payment becomes at that transition. Write the date down.

The bottom line

At 22.15% versus a rate tied to a 6.75% prime, the interest savings from consolidating into a HELOC are real and can be large. That is a legitimate reason to consider it.

But you are securing that debt with your home, and you are reopening the credit lines that produced it. Those two facts don't cancel the savings — they set the conditions under which the savings are worth capturing. Consolidation is a good tool for a debt problem that has already stopped growing, and a poor tool for one that hasn't.

Be honest with yourself about which one you have.
