Debt Consolidation Loan vs. Keeping Credit Card Debt: The Savings Calculation
October 21, 2026
Debt consolidation means replacing several debts, typically credit cards, with a single loan at a lower rate and a fixed payoff date. If the new rate is much lower than the average rate on your cards, you can reduce your monthly payment, your total interest, or both. The key is to compare the full cost of each path, including fees, and to avoid running up the cards again.
Example: $15,000 spread across cards at an average of 24% APR. Paying them off over 60 months would require $431.52 a month and cost $10,891 in interest. A five-year personal loan at 12% would have a payment of $333.67 and cost $5,020 in interest.

The loan reduces the payment by about $98 a month and the interest by $5,871. If you keep paying the old amount of $431.52 on the new loan, you would clear the debt in about 43 months, saving even more. If the lender charges a 5% origination fee ($750) that is deducted from the proceeds, the true cost is higher, and you must borrow slightly more than $15,000 to net the full amount. Including the fee, the savings are still more than $5,000.
A rate of 14% instead of 12% would give a payment of $349.02, so the rate you qualify for matters.
| Keep cards at 24% | Consolidation loan at 12% | |
|---|---|---|
| Balance | $15,000 | $15,000 |
| Term | 60 months | 60 months |
| Monthly payment | $431.52 | $333.67 |
| Total interest | $10,891 | $5,020 |
| Interest saved | - | $5,871 (before fees) |
Where the Savings Disappear
Origination fees of 1% to 8% reduce the benefit. A longer term can lower the payment but increase total interest: stretching the loan to 84 months at 12% reduces the payment to $264.79 but costs $7,242 in interest. Balance transfers with 0% promotional rates can be cheaper if you can repay within the promotional period. The biggest risk is behavioral: if you consolidate and then charge the cleared cards again, you end up with both the loan and new card debt.
To avoid this, consider removing the cards from your wallet, setting alerts, or closing the highest-risk accounts if that does not harm your credit too much.
Qualifying and Credit Effects
Rates for unsecured personal loans depend on credit score and income. People with scores in the 600s may be offered rates not much better than their card rates, in which case consolidation may not help. Applying causes a hard inquiry, and a new loan lowers the average age of accounts. Paying off the cards cuts utilization, which often raises your score within a billing cycle or two, so the net effect is often positive if you keep balances low afterward.
Other Ways to Consolidate
Balance transfer cards, home equity loans (which put your home at risk), 401(k) loans (which carry risks to your retirement and a repayment requirement if you leave your job), and nonprofit debt management plans, in which a credit counseling agency negotiates lower rates with your creditors. Each has trade-offs; compare total costs and risks.
A Decision Checklist
List each debt with its balance, rate, and minimum payment. Compute the weighted average rate. Get quotes from at least three lenders, including a credit union. Calculate total cost, including fees. Decide how you will prevent new debt. If you can pay the debt off within a year or two, the avalanche method of targeting the highest-rate card first may be enough without a new loan.
Frequently Asked Questions
Does debt consolidation save money?
It does when the new loan's rate and fees result in lower total cost than your current debts.
Will consolidating hurt my credit score?
There may be a small dip from the inquiry and new account, but lower utilization often raises scores.
What is a good rate for a consolidation loan?
Anything meaningfully below your average card APR, after fees, makes sense. Rates depend on credit.
Is a balance transfer better than a loan?
A 0% transfer can be cheaper if you can pay off the balance in the promotional period.
What if I run up my cards again?
You will end up worse off, so build a plan to avoid new debt before consolidating.
