A worked example on $20,000 of credit card debt, including the fees that lenders put in the fine print.
Updated September 2026 · Examples use illustrative rates, not live quotes.
A debt consolidation loan is a personal loan used to pay off several higher-interest balances, usually credit cards, and leave you with one fixed monthly payment. It can save thousands of dollars. It can also cost more than you expect if you only look at the rate. Here's how to tell the difference.
Credit cards usually charge rates in the 20% range, and card minimum payments are designed to shrink slowly. A personal loan for a borrower with good credit often carries a much lower fixed rate. It also has a fixed end date: the loan is fully paid off after its term, typically 2 to 7 years. The lower rate cuts your interest. The fixed term stops the debt from dragging on.
Suppose you have $20,000 spread across several credit cards at an average 22% APR.
| Plan | Monthly payment | Time to debt-free | Total interest / cost |
|---|---|---|---|
| Cards, paying $500/mo | $500 | 73 months (~6 yrs) | ≈ $16,378 |
| Cards, paying $600/mo | $600 | 52 months (~4.3 yrs) | ≈ $11,192 |
| Personal loan, 12%, 5 yrs, no fee | $445 | 60 months | ≈ $6,693 |
| Personal loan, 12%, 5 yrs, 5% origination fee | $468 | 60 months | ≈ $8,098 |
| Personal loan, 12%, 3 yrs, 5% origination fee | $699 | 36 months | ≈ $5,173 |
Compared with paying $500 a month on the cards, the 5-year loan with a fee costs about $8,300 less and has a lower payment. The 3-year loan costs the least overall, if the higher payment fits your budget.
Many personal loans charge an origination fee, commonly somewhere between 1% and 10% of the loan. Usually it's taken out of the money you receive. To end up with $20,000 in hand after a 5% fee, you have to borrow about $21,053, and you pay interest on the fee too. In the table, that fee adds about $1,400 to the 5-year loan.
That's why you should compare offers by APR, not by the interest rate. APR includes the origination fee, so an 11% loan with a 6% fee can cost more than a 12.5% loan with no fee. Prequalifying with several lenders usually uses a soft credit check that won't affect your score, so it's easy to compare.
Applying for the loan triggers a hard credit inquiry, which usually lowers your score slightly for a short time. After that, consolidation often helps. Paying off the cards drops your credit utilization, the share of your card limits you're using, which is one of the biggest factors in your score. Making every loan payment on time builds positive history. Avoid closing your oldest cards right away: closing them reduces your available credit and can raise your utilization again.
A consolidation loan pays your cards down to zero, but it doesn't close them. The biggest risk is running the card balances up again while you're still paying off the loan. Then you're carrying both debts. If you consolidate, consider putting the cards away, lowering their limits, or setting up autopay for anything you do still charge so it's paid in full each month.
Debt settlement companies are different from consolidation loans. They typically tell you to stop paying your creditors while they negotiate, which can seriously damage your credit and lead to collection calls and fees. Under FTC rules, they generally can't charge you before they've actually settled a debt. Any company asking for large fees up front is a red flag.
Put your card balances, rates, and current payment into the debt payoff calculator to see how long payoff takes today and how much interest you'll pay. Then put the loan amount (including any fee), APR, and term into the loan calculator. If the loan is cheaper and the payment fits, consolidation is probably worth it, as long as the cards stay paid off.
