Personal Loan vs. Credit Card Debt: Which Is Cheaper to Carry?

If you are carrying credit card balances at 22% to 29% APR and you receive a personal loan offer at 10% to 14%, the appeal is obvious. Using a fixed-rate personal loan to pay off revolving credit card debt — a strategy commonly called debt consolidation — can genuinely reduce your interest costs and give you a defined payoff date. But consolidation is not always the right move, the math does not always favor it, and done incorrectly it can leave you worse off than before. Understanding when it works and when it does not saves you from making an expensive mistake.

Key Takeaways

• Personal loans typically carry lower rates than credit cards — but always verify the actual numbers before assuming
• For consolidation to produce meaningful savings, the loan rate should be at least 4 to 5 percentage points lower than your card APRs
• Origination fees of 1% to 8% on personal loans can reduce or eliminate projected interest savings
• The most common consolidation failure: paying off cards with a loan and then charging the cards back up to new balances
• A 0% balance transfer card is often cheaper than a personal loan for balances payable within 12 to 21 months
• Calculate total cost for each path — current card trajectory, personal loan, and balance transfer — before deciding

Key Structural Differences

Credit cards and personal loans work very differently, and those structural differences determine which is cheaper in any specific situation:

• Credit cards: variable APR that the issuer can increase, revolving balance with no fixed end date, minimum payments that shrink as balance falls
• Personal loans: fixed interest rate that never changes, fixed monthly payment amount, guaranteed payoff date
• Credit cards: interest accrues daily using the daily periodic rate method on every dollar of outstanding balance
• Personal loans: simple interest amortized over the loan term — early payments contain more interest than later payments
• Personal loans: origination fees of 1% to 8% of the loan amount, typically deducted from the disbursed amount
• Credit cards: balance transfer fees of 3% to 5% if moving debt to a new card with a promotional rate

When a Personal Loan Wins on Total Cost

A concrete comparison. You have $8,000 in credit card debt at an average APR of 24%. At a $200 fixed monthly payment on the credit card, payoff takes approximately 57 months and costs approximately $3,400 in interest. Total amount paid: approximately $11,400.

Alternative: an $8,000 personal loan at 11% APR over 48 months. Monthly payment: approximately $207. Total interest: approximately $1,940. Total paid: approximately $9,940. Interest savings compared to the credit card path: approximately $1,460. If the loan carries a 3% origination fee ($240), net savings are approximately $1,220. That is meaningful money for a straightforward calculation.

The consolidation math works when: the loan rate is at least 4 to 5 percentage points lower than your card APR, and the origination fee consumes less than 30% to 40% of the projected interest savings. If both conditions are met, the personal loan is almost certainly the cheaper path.

When Consolidation Does Not Make Financial Sense

• The personal loan rate is only marginally lower than your current card APR — the savings do not justify the origination fee and the application process
• You have excellent credit and qualify for a 0% APR balance transfer card — that option is often cheaper than any personal loan rate for short-to-medium payoff timelines
• You are close to paying off the credit card balances anyway — consolidation for a small remaining balance with few months left is not worth the effort
• You have consolidated debt before and the card balances came back — this pattern suggests the root cause has not been addressed
• Your credit score is below 640 — you may not qualify for a personal loan rate low enough to make consolidation worthwhile

The Balance Transfer Alternative

If your credit score is 670 or above, a 0% APR balance transfer card is often the cheapest option for debt you can realistically pay off within 12 to 21 months. Many cards offer promotional periods of 15 to 21 months with no interest on transferred balances, charging a transfer fee of 3% to 5% of the amount moved.

On $8,000 transferred at a 3% fee: upfront cost is $240. If you pay off the entire balance during the promotional period, your total interest cost is $0 — just the $240 transfer fee. Compare that to approximately $1,940 in interest on the personal loan. The balance transfer option saves $1,700 in this scenario.

The risk is significant and must be taken seriously. Any balance remaining when the promotional period ends typically reverts to a standard APR of 25% to 30% — often higher than the original card. If you are not confident you can clear the full balance in time, a personal loan with a fixed rate and a guaranteed payoff date is the safer choice. Uncertainty about your payoff timeline is a strong argument for the loan over the transfer.

The Consolidation Trap That Defeats the Strategy

The most common way debt consolidation fails has nothing to do with the math or the rate. It happens when a borrower uses a personal loan to pay three credit cards to zero — feels a genuine sense of relief — and then gradually charges the cards back up over the following 6 to 12 months. They now carry both the personal loan payment and a growing new pile of credit card debt. Their total outstanding debt has increased, not decreased.

This outcome is documented often enough that financial counselors treat it as a predictable risk rather than a rare exception. The Consumer Financial Protection Bureau advises that consolidation addresses the symptom — high-rate debt — but not necessarily the underlying spending pattern that created it. If you consolidate, consider closing or freezing the paid-off cards immediately. Accepting the temporary credit score impact of closing accounts may be worth removing the path back into debt.

How to Evaluate Your Specific Situation

The right choice depends on your specific balance, APR, credit score, and how long you need to realistically pay off the debt. Use both calculators to run the numbers. Enter your current credit card balance and APR in the Credit Card Payoff Calculator to see your current interest trajectory. Then model a potential personal loan in the Loan Payoff Calculator using the rate you have actually been quoted — not a rate you assume you might get. Compare total interest paid in both scenarios, subtract any fees, and the decision becomes straightforward math rather than gut feeling.
