Consolidating credit card debt into a personal loan is common advice — but "common advice" and "actually run the numbers" aren't always the same thing. Here's a real comparison using our debt payoff calculator and loan calculator together, since this is exactly the kind of decision that benefits from combining two tools rather than one.
The setup
$15,000 in credit card debt at 22.99% APR — a realistic average rate. Two paths: keep paying it down on the card at $400/month, or consolidate into a fixed-term personal loan at a lower rate.
Option A — Stay on the credit card, $400/month
Time to pay off
67 months (5.6 years)
Total interest
$11,714.93
Total paid
$26,714.93
Option B — Consolidate into a personal loan, 11% APR, 3-year term
Monthly payment
$491.08
Time to pay off
36 months (3 years, fixed)
Total interest
$2,678.91
Total paid
$17,678.91
What the comparison actually shows
Consolidating saves $9,036.02 in interest and finishes 31 months (about 2.6 years) sooner — but it requires paying $91.08 more per month than the credit card scenario. That's the real, honest tradeoff: a meaningfully higher monthly payment in exchange for a dramatically lower total cost and a fixed payoff date. The credit card path has no fixed end date at $400/month in this scenario either — 67 months is simply how long it takes at that payment, and that number would stretch further if the payment ever dropped.
Why the rate difference matters this much
An 11.99-point gap between 22.99% and 11% APR sounds like "somewhat better," but interest compounds on the outstanding balance every month, so a lower rate compounds savings the same way a higher rate compounds cost. On a $15,000 balance carried for multiple years, that rate gap alone is responsible for the bulk of the $9,036 difference — the fixed 3-year term structure helps too, but it's the rate cut that's doing the heaviest lifting here.
What this comparison doesn't include
Real personal loans often carry origination fees (commonly 1-8% of the loan amount), which would add to the effective cost of Option B and aren't reflected in the 11% rate used here — check the APR specifically, not just the interest rate, when comparing real offers, since APR is designed to fold fees in. This comparison also assumes qualifying for an 11% rate, which depends on credit profile; a worse rate narrows the gap, and a strong enough credit profile could widen it further.
Run your own numbers
Your actual balance, card APR, and any personal loan offer you're considering will all shift this comparison. Run your card balance through the debt payoff calculator at your real payment amount, then run the loan offer's actual rate and term through the loan calculator — comparing the two total-interest figures directly is the same method used here.
The fee that changes the comparison
Personal loans frequently carry an origination fee, commonly one to eight percent, and it is usually deducted from the amount advanced rather than billed separately. Borrowing $15,000 with a five percent fee means $14,250 arrives while $15,000 is owed — so covering a $15,000 balance requires borrowing more than $15,000.
This is precisely why the advertised interest rate is the wrong number for comparison. The APR folds the fee in and is the figure that makes two offers comparable; a lender leading with an attractive rate is sometimes recovering it in an origination fee visible only in the APR. Our loan comparison calculator judges two offers on total cost rather than on whichever monthly payment looks smaller.
The risk no calculator can model
Consolidation clears the cards. It does not clear whatever produced the balances, and the cards are still open with their limits restored.
This is the most common way consolidation goes wrong: a year later there is a personal loan and card balances, and the household is worse off than before it started. The arithmetic in this walkthrough is entirely real, and it only holds if the spending pattern changed too. If the balances came from a one-off event — a medical bill, a period out of work — consolidation is straightforwardly sensible. If they accumulated gradually from ordinary spending, the loan treats a symptom.
A practical safeguard is to reduce the credit limits or close the cards as they are paid off, accepting the small credit-score cost of losing available credit in exchange for removing the temptation.
Secured consolidation raises the stakes
Home equity loans and cash-out refinances usually offer lower rates than unsecured personal loans, and the reason is that they are secured against your house. That converts unsecured debt, where the worst realistic outcome is severe credit damage and collection activity, into secured debt where the worst outcome is losing your home.
It also typically stretches repayment over a much longer term, so a lower rate can still produce more total interest — the same trap our refinance calculator is built to expose. The lower monthly payment is real, but it is a cash-flow change rather than a saving, and the additional risk is not reflected anywhere in the interest rate.
If the total is genuinely unmanageable rather than merely expensive, a non-profit credit counselling agency can negotiate directly with creditors in ways no calculator models, and that is a better first call than a secured loan.
Frequently asked questions
Does a personal loan really save money on credit card debt?
Often, because the rate is usually much lower — but check the APR rather than the interest rate. Origination fees of one to eight percent are common and are typically deducted from the advance, so covering a $15,000 balance means borrowing more than $15,000.
What is the biggest risk with debt consolidation?
Running the cards back up. Consolidation clears the balances but not the spending that created them, and the cards remain open with their limits restored. Reducing limits or closing cards as they clear removes the temptation.
Should I use my home equity to consolidate debt?
It offers a lower rate because it is secured against your house, which converts unsecured debt into debt that can cost you your home. It also usually stretches the term, so total interest can rise even at a lower rate.
