When consolidation wins — and when it doesn't

Consolidation saves when: new APR + amortized fee < weighted average APR of current debts

The comparison is honest only if it includes the fee and holds the timeline steady. A lower payment is easy to manufacture with a longer term — that's not savings, that's stretching. This calculator compares total dollars, not just monthly cash flow.

Worked example (defaults above)

$10,500 of card debt averaging ~22.6% APR, paid at $325/mo → about $4,700 interest, debt-free in ~4 years.

Consolidated at 12% over 3 years (3% fee rolled in): payment $359/mo, total cost about $2,400 — roughly $2,300 saved and a year sooner.

The consolidation trap to avoid

Consolidation moves debt; it doesn't erase the habits that created it. The most common failure mode: consolidate the cards, feel relief, then run the newly-empty cards back up — ending with the loan and new card debt. If you consolidate, freeze or close the paid-off cards until the loan is gone, and consider building a small emergency buffer first so surprises don't land on the cards. Compare alternatives: a 0% balance transfer (see credit card payoff), a home equity loan if you own (cheaper, riskier), or simply the avalanche method with no new loan at all.

Frequently asked questions

Does debt consolidation save money?

Only when the new rate (plus fee) is meaningfully below your weighted average current rate — like 22% cards into a 12% loan.

Does consolidation hurt my credit score?

Small temporary dip; often improves later as utilization drops — unless the cards get run back up.

What credit score do I need?

Approvals from ~600s, but rates that beat card APRs usually need 670+.
