A loan can lower your interest rate, but it trades one debt for another
Taking out a loan to pay off credit cards works only if the loan's interest rate is significantly lower than what you're paying on the cards, and only if you stop using the cards while you pay down the loan. A personal loan at 10% will save you money compared to credit card debt at 22%, but only if you don't rack up new balances on those same cards afterward. The math is straightforward: lower rate plus disciplined spending equals real savings. Without both pieces, you've just moved the problem around.
The loan itself doesn't fix the spending patterns that created the debt in the first place. If you borrowed $8,000 to clear five maxed-out cards, and then spent another $8,000 on those cards over the next two years while paying the loan, you've ended up with $16,000 in debt instead of $8,000. That's the trap most people fall into, and it's why lenders are willing to offer you a loan in the first place.
Key Takeaways
- A loan only saves money if its interest rate is at least 3 to 5 percentage points lower than your current credit card rates.
- You must stop using the credit cards you pay off, or you'll end up with both a loan and new card balances.
- Personal loans, home equity loans, and balance transfer cards are the three main routes, each with different rates and risks.
- If you can't commit to not using the cards again, a loan will make your situation worse, not better.
- A credit counselor can help you decide whether a loan fits your situation or whether a debt management plan would work better.
How to know if the math actually works in your favor
Start by writing down what you owe on each card and the interest rate on each one. Add them up. Then find out what interest rate you could get on a personal loan — you can check this without hurting your credit by using a prequalification tool from banks or credit unions you already use, or by calling a lender directly and asking for a rate estimate.
Subtract the loan rate from your average card rate. If the difference is less than 3 percentage points, the savings won't be worth the effort and the risk of taking on a new debt. If it's 5 points or more, the math probably works. Between 3 and 5 points, it depends on how long you'll take to pay off the loan — longer payoff periods make the savings smaller.
Then calculate how much you'll actually save. If you owe $10,000 across cards at an average of 20% interest, and you can get a personal loan at 12%, you'll save roughly $800 per year in interest. But if the loan charges an origination fee (usually 1% to 6% of the loan amount), that fee comes out of your savings. A $10,000 loan with a 3% origination fee costs you $300 right away, so your first-year savings drops to $500.
Personal loans: the most common route
A personal loan is unsecured debt, meaning you don't pledge any asset as collateral. Banks, credit unions, and online lenders all offer them. The interest rate depends on your credit score, income, and how much you want to borrow. Someone with a 750 credit score might get 8% to 12%; someone with a 600 score might get 18% to 24%. That's why a personal loan doesn't always beat credit card rates — if your credit is damaged, the loan rate might be nearly as high as the cards.
The loan term is usually 2 to 7 years. A shorter term means higher monthly payments but less total interest. A longer term spreads the payments out but costs more overall. Most lenders let you pay off early without penalty, so you can choose a longer term for breathing room and pay faster if your situation improves.
Credit unions often offer lower rates than banks if you're a member, so check with yours first. Online lenders like LendingClub, Upstart, and SoFi advertise fast funding — sometimes within one business day — but read the fine print on fees. Some charge origination fees, some don't; some charge prepayment penalties, some don't.
Balance transfer cards: lower rates for a limited time
A balance transfer card is a credit card that offers 0% interest for a set period — usually 6 to 21 months, depending on the card and your credit score. You transfer your existing balances to this new card and pay no interest during the promotional period. After that, the rate jumps to the card's regular APR, which is usually 15% to 25%.
This works only if you can pay off the entire transferred balance before the promotional period ends. If you owe $5,000 and have 12 months at 0%, you need to pay roughly $417 per month to clear it. If you can't, the remaining balance will be charged the regular rate, and you'll be worse off than before.
Balance transfer cards also charge a transfer fee, usually 3% to 5% of the amount you transfer. A $5,000 transfer with a 3% fee costs $150 upfront. That fee is added to your balance, so you're actually paying off $5,150. The math only works if the interest you save during the promotional period exceeds the transfer fee — which it usually does, but only if you actually pay it off in time.
Home equity loans and lines of credit: higher risk, lower rates
If you own a home, you can borrow against the equity you've built up. A home equity loan gives you a lump sum; a home equity line of credit (HELOC) works like a credit card — you draw what you need and pay interest only on what you use. Both typically have interest rates 2 to 4 percentage points lower than personal loans because the lender can take your house if you don't pay.
This is the key trade-off: you get a lower rate, but you're putting your home at risk. If you lose your job or face an emergency and can't make payments, the lender can foreclose. A personal loan or balance transfer card can't do that. Use a home equity loan only if you're confident you can make the payments and you understand that risk.
What to do with the credit cards after you pay them off
This is where most people fail. After you use the loan to pay off the cards, you have two choices: close the cards or keep them open but unused. Closing them will hurt your credit score slightly because it reduces your available credit and shortens your credit history. Keeping them open but unused is usually better for your score, but it requires discipline — you have to not use them.
Some people cut up the cards or lock them away. Others ask a trusted family member to hold them. Some set up a small automatic charge (like a streaming service) and pay it off monthly, just to keep the account active. The point is to make using them inconvenient enough that you won't reach for them when you're tempted.
If you've used a balance transfer card, you'll have a new card with a $0 balance and a 0% promotional rate. Don't use it for new purchases. Treat it as a tool you used once, not as a new source of credit.
When a loan is the wrong choice
A loan doesn't work if you're still spending more than you earn. If you're adding $500 per month to credit cards because your expenses exceed your income, a loan just delays the problem. You'll pay off the loan balance, keep adding to the cards, and end up with both debts again. Before you take out a loan, make sure you can actually live within your means.
A loan also doesn't work if your credit is so damaged that you can't get a rate better than your cards. If you're being offered 22% on a personal loan and your cards are at 20%, you're not saving anything. In that case, a debt management plan through a nonprofit credit counselor might be a better option — they can often negotiate lower rates directly with your card issuers without you taking on new debt.
Finally, a loan doesn't work if you're in a crisis. If you're facing eviction, foreclosure, or wage garnishment, a loan won't solve that. You need when ready help, which might come from emergency information programs, legal aid, or a bankruptcy attorney. A credit counselor can help you figure out which.
Frequently Asked Questions
Will taking out a loan hurt my credit score?
Yes, initially. A hard inquiry and a new account will lower your score by 5 to 10 points. But as you pay the loan on time, your score will recover and usually improve, because you'll have a mix of credit types and a lower overall balance-to-limit ratio. The short-term dip is worth it if the loan actually saves you money.
What if I can't get a loan because my credit is too low?
A credit union might offer a loan even with lower credit, or a co-signer with better credit can help you get approved. If neither is possible, a debt management plan through a nonprofit counselor is often the next step. They work with your creditors to lower rates without you borrowing more.
Can I use a 401(k) loan to pay off credit cards?
You can borrow from your 401(k) if your plan allows it, usually at a low rate. But if you leave your job, the loan becomes due when ready — if you can't repay it, it's treated as an early withdrawal and you'll owe taxes and penalties. This is risky and should be a last resort.
How long does it take to get approved for a personal loan?
Online lenders can approve and fund within one to three business days. Banks and credit unions usually take three to seven business days. The timeline depends on how quickly you submit documents and how straightforward your process is.
What if I pay off the loan early?
Most personal loans have no prepayment penalty, so you can pay it off whenever you want without extra fees. Paying early saves you interest. Some lenders do charge prepayment penalties, so read the terms before you sign.
