Using a personal loan to consolidate credit card debt means taking out one fixed-rate loan to pay off several credit card balances at once, replacing multiple variable, often high-rate revolving debts with a single, predictable installment payment. Whether this actually saves money depends on the math, not just the convenience.
The core calculation
The strategy only saves money if the personal loan's APR is meaningfully lower than the blended average APR across your current credit card balances. If your cards average 24% APR and you qualify for a personal loan at 11%, the savings can be substantial over the loan's term. If your credit profile only qualifies you for a personal loan at 22%, the savings shrink dramatically or disappear.
Calculate your blended average APR by weighting each card's rate by its balance, not by simply averaging the rates — a card with a small balance at a high rate matters less to your overall cost than a card with a large balance at a moderate rate.
The behavioral risk that complicates the math
Consolidation pays off the cards, but it doesn't close them unless you choose to. If old habits return and the now-empty cards get used again, you can end up with both the original credit card debt rebuilding and the new personal loan payment — a worse position than before consolidating. This isn't a flaw in the math, but it's the single most common reason consolidation fails to deliver lasting benefit.
What a personal loan actually fixes — and what it doesn't
A personal loan converts variable, revolving high-interest debt into fixed, predictable installment debt with a clear end date. It does nothing to address the spending pattern that created the debt in the first place. For consolidation to actually work long-term, the underlying spending behavior needs to change alongside the loan, not instead of it.
- Calculate your true blended average APR across all cards before assuming consolidation will save money
- Get a real loan offer and compare its APR directly against that blended rate
- Decide in advance whether you'll close, freeze, or simply avoid using the paid-off cards going forward
- Build a basic spending plan alongside the loan, not just the loan itself, to avoid rebuilding the same debt
Frequently asked questions
Does consolidating hurt my credit score?
There's often a small short-term dip from the new account and hard inquiry, but utilization on the paid-off cards typically drops significantly, which tends to help the score over the following months.
Should I close the credit cards after consolidating?
Not necessarily. Closing cards can reduce your total available credit and raise your utilization ratio elsewhere. Many people choose to keep cards open but unused, or set a firm personal rule about future use instead of closing them outright.
