Balance Transfer vs HELOC vs Personal Loan vs 401(k) Loan on $13,800 in Credit Card Debt: The $340-a-Month Break-Even (October 2026)
Say you're carrying $13,800 across four credit cards at roughly 24% APR. You can afford $477.45 a month. This week's headlines don't make the choice any easier.
NerdWallet's mortgage rate roundup for Friday, October 2 ("A Little Lower, Still Above 7%") says rates dipped but the relief is "pretty minimal." The Bureau of Labor Statistics' Major Economic Indicators page shows CPI up 0.4% in August 2026, unemployment at 4.2% in September, and preliminary September payrolls of just +29,000. Average hourly earnings rose a preliminary $0.05, which is about $2 a week for someone working 40 hours.
So prices are rising, hiring looks thin, and borrowing is still expensive. That's the setting for choosing between a balance transfer, a HELOC, a personal loan, and a 401(k) loan. Below I run all four head-to-head with the same payment, then show which variable flips the winner. This is the kind of comparison Tevarindo is built to run, but I'll show the work so you can follow it.
The Example: One Debt, Five Paths
Everything below is a worked example with assumed terms, not live quotes. Your offers will differ.
| Path | Assumed terms |
|---|---|
| Keep paying the cards | 24% APR, $13,800 balance |
| Personal loan | 12% APR, 36 months, 4% origination fee (so you borrow $14,375 to net $13,800) |
| HELOC | 8.75% variable APR, $600 in upfront costs rolled into the draw ($14,400) |
| 0% balance transfer | 18 months at 0%, 3% fee ($414), then 24% on what's left |
| 401(k) loan | 9.5% interest paid to your own account, $75 fee, 7% assumed market return |
Term normalization: to compare fairly, every option gets the same $477.45 monthly payment. That payment is what the 36-month personal loan requires. The cheaper options simply finish sooner. If you compared "5-year HELOC vs 18-month transfer" without this step, you'd mostly be comparing time, not cost.
Effective APR is the rate that makes your net proceeds ($13,800) equal to the present value of every payment. It's the same idea as a loan's APR, but fees are included:
13,800 = Σ 477.45 ÷ (1 + r)ᵗ
The monthly r that solves it, times 12, is the effective APR. The five-calculation walkthrough covers the formula in detail.
Head-to-Head Results at $477.45 a Month
| Option | Effective APR | Months to payoff | Fees + interest | Saved vs. cards | NPV of cost at 6% discount |
|---|---|---|---|---|---|
| Keep paying cards | 24.0% | ~43.6 | ~$7,007 | n/a | ~$4,859 |
| Personal loan | ~14.9% | 36 | $3,388 | ~$3,619 | ~$1,894 |
| HELOC | ~11.8% | ~34.2 | ~$2,519 | ~$4,488 | ~$1,167 |
| 0% balance transfer | ~6.6% | 32 | ~$1,267 | ~$5,740 | ~$106 |
| 401(k) loan | see below | ~33.2 | ~$1,517 (est.) | ~$5,490 (est.) | n/a |
All figures are rounded and approximate. "NPV of cost" is the present value of all payments minus the $13,800 you received, discounted at an assumed 6% a year.
Three things stand out:
- The personal loan has the highest effective APR of the four. The stated 12% becomes about 14.9% once the 4% fee is included. The fee is paid on day one but the money is only borrowed for 36 months.
- The HELOC's advantage is real but smaller than its sticker rate suggests. An 8.75% rate becomes ~11.8% effective after $600 in costs.
- The balance transfer wins by a wide margin here, but only under a specific condition. I'll get to that next.
The gap between the cheapest and most expensive of the four consolidation options is about $2,121 (balance transfer vs. personal loan). That's far more than any Oct. 6 National Taco Day BOGO deal will save you, though NerdWallet's roundup is still worth a look if you're hungry.
The $340 Break-Even: When the Balance Transfer Stops Winning
The balance transfer's low cost depends on paying it down fast. At $477.45 a month, you carry about $5,620 past the promo period and pay roughly $853 in interest on it. At $790 a month ($14,214 ÷ 18), you'd clear the whole thing inside the promo and the only cost would be the $414 fee.
Now consider paying less. Here's the transfer against the HELOC at several payment levels, using the same assumptions:
| Monthly payment | Balance transfer total cost | HELOC total cost | Cheaper option |
|---|---|---|---|
| $320 | ~$4,104 | ~$3,717 | HELOC |
| ~$340 | ~$3,421 | ~$3,486 | About even |
| $400 | ~$2,124 | ~$2,964 | Balance transfer |
| $477.45 | ~$1,267 | ~$2,519 | Balance transfer |
Below roughly $340 a month, the HELOC beats the balance transfer in this example. After the promo ends, the leftover balance accrues at 24% and swamps the savings. The transfer isn't a better product in general. It's a better product for people who can pay aggressively during the promo window.
That's a pattern I see in the math over and over. The headline rate matters less than whether your payment capacity matches the product's structure. Our post on when a lower rate actually costs you more goes deeper on this.
You can plug your own balance, payment, and offers into this exact comparison at Tevarindo to find where your break-even sits.
The HELOC: A Variable Rate in a Sticky-Rate Environment
NerdWallet's October 2 report puts mortgage rates still above 7%. HELOCs aren't priced off that number. They typically float with a benchmark plus a margin set by your lender. But the report tells you borrowing hasn't gotten meaningfully cheaper.
Because a HELOC rate can move, test it. If the example's 8.75% rate rises two points to 10.75% and you keep paying $477.45:
- Months to payoff: ~35.3
- Fees + interest: ~$3,059, up from ~$2,519 (about $540 more)
That's still ~$330 cheaper than the fixed-rate personal loan in this example. So a two-point rise doesn't change the ranking here. A larger rise, or a lender with a bigger margin, could.
The other cost is that your home secures the loan. A card default costs you credit and collections calls. A HELOC default can put your house at risk. That doesn't make it wrong, but it belongs in the decision.
If you're weighing this at similar rate levels, we ran a related comparison in $18,000 in credit card debt with mortgage rates above 7%.
The 401(k) Loan: The Cost Is a Bet on the Market
The interest on a 401(k) loan goes back into your own account, so the true cost is mostly growth you give up while the money is out. In this example:
- Average outstanding balance over ~33 months: about $7,456
- Foregone growth at a 7% return: about $1,442
- Plus the $75 fee: about $1,517
This treats the interest you pay yourself as a wash, since it moves from your paycheck into your account. Pre-tax accounts add tax wrinkles worth checking with your plan administrator.
The cost swings with returns:
| Assumed market return | Estimated 401(k) loan cost |
|---|---|
| 3% | ~$693 |
| 7% | ~$1,517 |
| 12% | ~$2,547 |
At a 12% return, the 401(k) loan costs about the same as the HELOC. At 3%, it's the cheapest option on the table. You're making a market prediction whether you intend to or not.
The bigger risk is your job. BLS shows +29,000 preliminary payrolls and 4.2% unemployment, which isn't a crisis but isn't a booming labor market either. Here's why it matters. After 12 payments in this example, you'd still owe about $9,266. If you leave your job and can't repay or roll it over by your tax filing deadline (including extensions), the plan may treat the unpaid balance as a distribution. In the 22% bracket and under 59½, that's roughly 22% tax plus a 10% penalty, or about $2,965 on top of losing the job. Check your own plan's rules, since they vary.
Credit Score Impact: Model Utilization, Not Guesses
I won't predict exact point changes, because they depend on your file and the scoring model. But you can model utilization, which is a major factor. Assume your four cards have $18,000 in total limits:
| Scenario | Total revolving limits | Card balances | Utilization |
|---|---|---|---|
| Today | $18,000 | $13,800 | 76.7% |
| After personal loan | $18,000 | $0 | 0% (plus a new installment loan) |
| After balance transfer (new $15,000 card, old cards stay open) | $33,000 | $14,214 | 43.1% overall, 94.8% on the new card |
| After HELOC | $18,000 | $0 on cards | 0% on cards; HELOC reporting varies by lender |
| After 401(k) loan | $18,000 | $0 | 0%; no credit check or reporting |
The balance transfer looks great on cost but leaves one card nearly maxed. Closing the old cards afterward would shrink your total limits and push overall utilization back up. There's also a hard inquiry on the personal loan, balance transfer, and HELOC applications that the 401(k) loan avoids. If you're planning a mortgage or auto loan in the next six months, that timing matters.
Fees Are Hurdle Rates (Chase and U.S. Bank Remind Us)
NerdWallet's report on Chase and IHG describes a new $350-annual-fee card and an increase on the IHG One Rewards Premier World Elite Mastercard to $150. The standard way to evaluate an annual fee is to ask what value you need to earn back to break even.
Consolidation fees work the same way:
- The balance transfer's $414 fee is a 3.0% hurdle on $13,800.
- The HELOC's $600 is a 4.3% hurdle.
- The personal loan's $575 origination fee is a 4.2% hurdle.
Each fee has to be earned back through lower interest. At a 24% starting APR, all three clear easily. As your starting rate falls, or your balance shrinks, fixed fees can flip a winner. Our October 2026 fee break-even test on $18,500 shows where that happens.
One more note: NerdWallet's U.S. Bank piece covers two new business cards launched September 28. They're designed for business spending, so they're not a drop-in fix for personal card balances. New product launches are a reason to compare offers, not a reason to rush.
Which Variable Flips the Winner?
| If this is true for you... | The ranking may shift toward... |
|---|---|
| You can pay $400+ a month and qualify for a 0% offer with a high enough limit | Balance transfer |
| You can only pay under ~$340 a month | HELOC or fixed-rate personal loan |
| You have home equity but worry about rate rises | Fixed-rate personal loan |
| Your job is stable and you expect low market returns | 401(k) loan |
| Your job is uncertain | Avoid the 401(k) loan |
| You're applying for a mortgage soon | Whichever option adds the fewest inquiries and least utilization risk |
| Your credit tier gets a personal loan quote above 18% | HELOC or balance transfer gain ground |
But Your Numbers Will Differ
Every figure here depends on assumptions I chose: a 24% card rate, 12% personal loan, 8.75% HELOC, 3% transfer fee, 18 promo months, 7% market return, and a 6% discount rate. Change any one and the ordering can move. The $340 break-even, the $3,059 HELOC stress case, and the $2,965 job-loss tax hit are specific to this example.
What to gather before you compare:
- Each card's balance and APR (to get your weighted rate)
- The monthly payment you can actually sustain
- Real quotes, with fees, for each option you qualify for
- Your home equity and the HELOC's margin and rate cap
- Your total card limits, for utilization modeling
- Your 401(k) plan's loan terms and what happens if you leave your job
That's a lot of inputs, and it's why rules of thumb fail. If you'd rather not build the spreadsheet, Tevarindo runs the effective APR, term normalization, NPV, utilization, and total-interest-saved comparison side by side using your numbers, so you can see where your break-even sits before you apply for anything.
