Take a hypothetical homeowner who needs $10,000 for a kitchen repair that can’t wait. She has three realistic ways to pay: a 36-month personal loan, the credit card already in her wallet, or a new card with a 0% introductory APR on purchases. The numbers below are illustrative, but the rates are in the range lenders were actually charging in 2026.
Option 1: a personal loan. Say she qualifies for a 12% APR over 36 months, with a 5% origination fee taken out of the proceeds. To walk away with the full $10,000, she has to borrow about $10,526. Her payment is roughly $350 a month, and over three years she repays about $12,586. Total cost of the money: around $2,586.
Option 2: her existing credit card at 22% APR. If she puts the $10,000 on the card and pays the same $350 a month, the balance takes about 41 months to clear and she pays roughly $4,240 in interest. Same monthly budget, five extra months, and about $1,650 more in cost.
Option 3: a card with a 15-month 0% intro APR on purchases. At $350 a month, she pays down $5,250 during the promotion, leaving $4,750 when the standard 22% rate kicks in. Clearing that takes about 16 more months and costs roughly $675 in interest. If she could manage about $667 a month instead, she’d pay it off inside the promo window and owe no interest at all.
So the cheapest path on paper is the 0% card, and the most expensive is the card she already has. But that ranking flips easily, and the reasons why matter more than the arithmetic.
The three options side by side
| Hypothetical $10,000 expense | Personal loan (12% APR, 5% fee) | Existing card (22% APR) | 0% intro card (15 months, then 22%) |
|---|---|---|---|
| Monthly payment used | About $350, fixed | $350, by choice | $350, by choice |
| Time to pay off | 36 months, guaranteed | About 41 months | About 31 months |
| Approximate total cost | $2,586 | $4,240 | $675 |
| Rate can change? | No (fixed rate) | Yes, variable APR | Yes, after the promo |
| What it depends on | Approval and fee size | Your discipline to pay more than the minimum | Approval, a high enough limit, and paying on time |
For context on the rates: the Federal Reserve’s G.19 consumer credit release showed commercial banks charging just under 12% on 24-month personal loans in mid-2026, while credit card accounts that were assessed interest averaged around 22%. Your own offers can land well above or below those averages depending on your credit.
Why the personal loan often wins for people who carry balances
The existing card in the example only cost $4,240 because our hypothetical borrower kept paying $350 a month. Nothing forces that. Card minimum payments are often set at something like 1% of the balance plus interest, which on $10,000 at 22% is under $300 at first and shrinks as the balance shrinks. Follow the minimum and the payoff stretches out for many years. Our breakdown of what paying only the minimum really costs shows how quickly that adds up.
A personal loan removes the choice. It’s installment debt: a fixed payment, a fixed end date, and a rate that won’t move. For anyone who knows they tend to pay the minimum when money is tight, that structure is worth real money.
There’s also a credit score angle. Revolving balances count toward your credit utilization; installment loans generally don’t affect it the same way. Moving $10,000 off a card and onto a loan can lower your utilization noticeably, though a new account and a hard inquiry nudge the score in the other direction for a while.
Where the 0% card earns its spot
An intro-APR card is the cheapest money in the example, and it can genuinely cost nothing. It works best when three things are true:
- The expense fits under the credit limit you’re actually approved for. Many people get a limit well below what the project costs.
- You can pay the balance off before the promotion ends, or close to it.
- You won’t add new spending to the card during the promo period.
Watch the difference between a true 0% APR and “deferred interest,” which is common on store cards and medical financing. With deferred interest, if any balance remains when the promo ends, you can be charged interest retroactively on the original amount from day one. A real 0% intro APR only charges interest going forward. The CFPB has warned card issuers that promotional offers must spell out these conditions clearly, and our guide to 0% intro APR fine print covers what else to check.
Also check the card’s standard APR. Once the promo ends, anything left over is charged at that rate, which is often higher than what a personal loan would have cost.
The fee that can erase the loan’s advantage
Origination fees on personal loans commonly run from nothing to several percent of the loan amount, and some lenders charge more for borrowers with weaker credit. In the example, the 5% fee added more than $500 to the cost. A no-fee loan at the same 12% rate would have cost about $1,957 instead of $2,586.
Always compare APRs, not just interest rates, because APR folds the fee into a single annual number. And if you might pay the loan off early, remember the fee is paid upfront and doesn’t shrink. We break that down in how origination fees work.
Smaller expenses play by different rules
For a $1,500 car repair you can clear in two or three months, a personal loan rarely makes sense. Many lenders set minimum loan amounts, fees take a bigger bite of small loans, and three months of credit card interest on $1,500 at 22% is in the range of $50 to $60. The math tilts toward the card when the balance is small and the payoff is fast.
Above a few thousand dollars, or whenever payoff will take longer than a year, the comparison gets closer and the personal loan’s fixed schedule starts to look better.
The verdict depends on this
The cheapest option is whichever one you’ll actually pay off on the schedule you assume. A few questions settle it quickly:
- Can you clear the balance within a 0% promo window? If yes, and you qualify for a limit large enough, the intro card is hard to beat.
- Will payoff take more than about a year? A fixed-rate personal loan usually costs less than a standard-rate card over that stretch, especially with a low or no origination fee.
- Do you tend to pay the minimum when things get tight? Then the structure of a loan is protecting you from yourself, and that’s worth paying for.
- Is the expense small and short-term? Using a card you already have and paying it down aggressively is often simplest.
Run your own numbers with the actual APRs you’re offered. Prequalifying with a few lenders usually involves only a soft credit check, so you can see real rates before committing to anything.
