Where the money comes from when you need a repair
When your car needs a repair you can't afford right now, you have several ways to pay: a personal loan from a bank or credit union, a credit card, a loan specifically marketed for car repairs, or a payment plan through the repair shop itself. Each one works differently, costs different amounts, and affects your credit in different ways. The right choice depends on how much you need, how quickly you need it, and what interest rate you can actually get.
Most people don't plan for repairs, so you're working with limited time. That pressure is exactly when lenders count on you making a rushed decision. Understanding what each option actually costs before you commit means you won't end up paying far more than the repair itself.
Key Takeaways
- Personal loans from banks or credit unions usually have lower interest rates than credit cards, but take a few days to fund and require a credit check.
- Credit cards are fastest if you already have one, but carry much higher interest rates unless you pay the full balance within the promotional period.
- Repair shop payment plans often have no interest for a set period, but charge high rates after that period ends and may require a credit check.
- The total cost of borrowing depends on the interest rate, how long you take to repay, and any fees — not just the repair bill itself.
- If your credit score is very low, a credit card or shop payment plan may be your only option, even though they cost more.
Personal loans: slower but usually cheaper
A personal loan from a bank, credit union, or online lender is money you borrow in one lump sum and repay in fixed monthly payments over a set period — typically two to five years. The lender checks your credit, income, and debt before deciding whether to lend and what interest rate to charge you. If approved, the money usually arrives in your bank account within one to three business days.
Personal loans typically charge between 6 and 36 percent interest per year, depending on your credit score and the lender. A credit union usually charges less than a bank, and a bank usually charges less than an online lender. If you borrow $2,000 at 15 percent interest over three years, you'll pay roughly $650 in interest on top of the $2,000 itself. The same $2,000 on a credit card at 22 percent interest, paid over three years, costs roughly $1,100 in interest — nearly double.
The downside is time. If your car is broken down and you need it fixed today, a personal loan won't help. You also need decent credit to get approved at a reasonable rate. If your credit score is below 600, you may not be approved at all, or you'll be offered a rate so high that a credit card becomes cheaper.
Credit cards: fastest if you already have one
If you already own a credit card, charging a repair to it is the fastest way to pay. The money is available when ready — you just hand over the card at the shop. No process, no waiting, no credit check.
The catch is interest. Most credit cards charge 18 to 25 percent interest per year on unpaid balances. Some cards offer a promotional period — often 0 percent interest for 6 to 12 months — but only if you're approved for that card or already have that promotion active. If you pay off the full balance before the promotional period ends, you pay no interest at all. If you don't, the regular interest rate kicks in on whatever balance remains.
Credit cards make sense for repairs under $1,000 if you can pay the full balance within the promotional period, or if you can pay it off in a month or two anyway. They make no sense if you'll carry the balance for years — the interest will far exceed what a personal loan would cost. Also, if you don't already have a credit card, explore for one takes time and requires a credit check, so it's not actually faster than a personal loan.
Repair shop payment plans: interest-free at first, then expensive
Many repair shops offer their own payment plans, often through a third-party lender like Affirm or CareCredit. These plans typically charge 0 percent interest if you pay off the full amount within a set period — often 6 to 12 months. After that period, the interest rate jumps to 18 to 29 percent per year, and it applies retroactively to the entire original balance if you haven't paid it off.
This sounds good until you do the math. If you borrow $3,000 at 0 percent for 12 months, your monthly payment is $250. But if you miss the important date by even one month and still owe $500, that $500 suddenly starts accruing interest at 25 percent. More importantly, if you can't pay off the full amount in 12 months, the interest retroactively applies to the entire $3,000 from day one — meaning you'll owe roughly $375 in interest you didn't expect.
Shop payment plans also usually require a credit check and approval, so they're not actually faster than a personal loan. The real advantage is that the shop handles the paperwork and you don't have to shop around for a lender. The real risk is that promotional period ending and catching you off guard.
When your credit score is very low
If your credit score is below 600, most banks and credit unions will deny you or offer rates above 30 percent. In that situation, a credit card or shop payment plan may be your only realistic option, even though they cost more. Some online lenders specialize in bad-credit personal loans, but they charge 25 to 36 percent interest and often include fees that add another 5 to 10 percent to the total cost.
Before you borrow, ask yourself whether the repair is truly necessary right now. If the car is drivable and the repair can wait a few months, waiting gives you time to improve your credit score — even a small improvement can lower the interest rate you're offered by several percentage points, saving you hundreds of dollars. If the repair is urgent, a credit card or shop plan is faster than waiting to build credit, but understand that you're paying a premium for speed.
What to compare before you decide
Don't compare just the interest rate. Compare the total cost: the interest rate, the length of the loan, any fees, and what happens if you pay early. Some lenders charge a prepayment penalty if you pay off the loan faster than scheduled, which means you can't save money by paying it down quickly. Some charge an origination fee (a percentage of the loan amount) just for processing the process.
Use a loan calculator to see the total cost under different scenarios. If you're comparing a $2,000 personal loan at 12 percent over 36 months versus a credit card at 20 percent that you'll pay off in 24 months, the personal loan costs roughly $400 in interest while the credit card costs roughly $430 — close enough that speed and convenience might matter more. But if you'll carry the credit card balance for 36 months, it costs roughly $1,300 in interest, making the personal loan far cheaper.
How borrowing for a repair affects your credit
Taking out any loan or using a credit card creates a hard inquiry on your credit report, which temporarily lowers your score by a few points. Opening a new account also lowers your score slightly. But making on-time payments on the new loan actually helps your credit over time, because it shows you can handle debt responsibly.
The bigger risk is missing a payment. One late payment can drop your score by 100 points or more and stay on your report for seven years. If you're already stretched thin financially, borrowing for a repair might push you into a situation where you can't make the payment. In that case, it's worth asking whether you can delay the repair, fix it yourself if it's straightforward, or find a cheaper repair shop.
Frequently Asked Questions
Can I get a personal loan if I have bad credit?
Yes, but the interest rate will be much higher — typically 25 to 36 percent. Some online lenders specialize in bad-credit loans, but read the fine print for origination fees and prepayment penalties. A credit card or shop payment plan may actually be cheaper in your situation.
What's the difference between a personal loan and a car loan?
A personal loan is unsecured, meaning the lender has no claim to your car if you don't pay. A car loan is secured by the car itself, so the lender can repossess it if you default. Car loans usually have lower interest rates, but you can't use one for a repair — only to buy a car.
Should I use a credit card or a personal loan?
Use a credit card if you can pay off the full balance within the promotional period (usually 6 to 12 months), or if the repair is small and you can pay it off in a month or two. Use a personal loan if you need to spread payments over a longer period or if you don't have a credit card yet.
What happens if I can't pay off a shop payment plan before the interest kicks in?
The interest rate jumps to 18 to 29 percent and usually applies retroactively to the entire original balance. If you borrowed $3,000 and miss the important date, you'll owe interest on the full $3,000 from day one, not just on what you still owe. Contact the lender when ready if you think you'll miss the important date — some will extend the promotional period if you ask.
Does borrowing for a car repair hurt my credit score?
explore for the loan causes a small temporary drop. Opening the account causes another small drop. But making on-time payments actually helps your score over time. Missing a payment, however, can drop your score by 100 points or more and damage it for years.
