If you own a California home and carry a credit card balance, you have probably done the rough math already. The card charges one rate, your equity could be borrowed at a much lower one, so moving the debt should save money.
It can. But the rate is only half of the calculation. The other half is how fast you pay the new loan off, and that is where a lot of consolidations quietly go wrong. Here are the real numbers on stated assumptions, the two traps we see most often, and the situations where we would tell you not to do it.
Quick summary: Moving card debt to home equity can save a lot of interest if you keep making roughly the payment you were making on the cards. If you drop to the new, lower minimum or stretch the balance over 20 years, you can end up paying more interest than you would have on the cards, and the debt is now secured by your house.
According to the Federal Reserve's consumer credit report, the average credit card interest rate for accounts that were actually assessed interest was 22.15% in May 2026, the most recent reading. Across all accounts it was 20.94%. If you carry a balance month to month, the first number is the one that describes you.
HELOCs are usually variable and priced off the prime rate plus a margin. The prime rate was 7.00% as of September 21, 2026, up from 6.75% after the Federal Reserve raised its target range on September 16. Margins vary with your credit, your combined loan-to-value, and the lender, so for the illustration below we assume a HELOC rate of 8.50% (prime plus 1.50). That is an assumption for arithmetic, not a quote.
Take a household with $40,000 spread across credit cards at 22.15%, paying $1,200 a month. Here is how that same balance plays out depending on what happens after it moves to home equity. All figures ignore fees and assume no new charges.
| Scenario | Monthly payment | Time to pay off | Total interest |
|---|---|---|---|
| Stay on the cards at 22.15% | $1,200 | 53 months | $22,674 |
| HELOC at 8.50%, keep paying $1,200 | $1,200 | 39 months | $5,790 |
| HELOC at 8.50%, stretched over 20 years | $347 | 240 months | $43,311 |
| HELOC at 8.50%, interest-only minimum | $283 | Never, while interest-only | $3,400 a year, principal untouched |
Read the second row first. Keep the same $1,200 payment and, on these assumptions, you could be debt-free about 14 months sooner and pay roughly $16,900 less interest. That is the version of consolidation that works.
Now read the third row. Same loan, same rate, but the payment is set to a 20-year schedule because it feels comfortable. The monthly bill drops by more than $850, and total interest nearly doubles compared with staying on the cards. A lower rate does not save money if you use it to borrow for longer.
Most HELOCs start with a draw period, often 10 years, during which the required payment can be interest only. On $40,000 at 8.50%, that minimum is about $283 a month, compared with the roughly $738 a month in interest the same balance was costing on the cards.
That drop feels like relief, and it is where the trap lives. Pay only the minimum and the $40,000 is still $40,000 when the draw period ends. At that point principal becomes mandatory on a shorter schedule, and the payment jumps. We walk through that transition in HELOC draw period vs. repayment period.
The fix is simple and entirely in your control: set up an automatic payment for the amount you were already paying on the cards, not the lender's minimum.
Consolidation empties the cards. It does not close them, and it does not change whatever filled them. The Consumer Financial Protection Bureau is blunt about this: if the debt built up because spending ran ahead of income, a consolidation loan probably won't help unless spending comes down or income goes up.
The worst outcome is not staying where you started. It is owing the equity loan and a fresh set of card balances two years later, with less equity left in the house. If you are not confident the spending has stopped, fix that first. Consolidation is a tool for a problem that is already under control.

You get one lump sum, a fixed rate, and a payment that includes principal from month one, which removes both the interest-only trap and the rate risk. The tradeoff is less flexibility. Our home equity loan vs. HELOC comparison goes through how each behaves.
What we would rarely suggest right now is a cash-out refinance just to clear cards. Freddie Mac's survey had the 30-year fixed at 7.03% as of September 24, 2026, its first reading above 7% since January 2025. If your first mortgage carries a rate well below that, replacing the whole loan to consolidate $40,000 means repricing hundreds of thousands of dollars upward. A second lien leaves that first mortgage alone, which is the core idea behind accessing equity without refinancing.
It tends to work when the card balances came from a one-time event such as a medical bill, a move, or a job gap, the spending has since normalized, you have steady income, and you will commit to a payment close to what you were paying before.
It tends not to work when balances keep growing month to month, when the only appeal is a smaller payment, or when income is uncertain enough that you would struggle with a payment secured by your home. In those cases a nonprofit credit counselor, which the CFPB suggests considering, may be a better first stop.
If you do move forward, pricing varies meaningfully between lenders on the same borrower, which is why comparing through a broker rather than a single bank is worth a few minutes. You can request a free quote without a credit pull.
