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.

Worked example — when consolidation loses money

Same $10,500 balance, but this time the offer is a 3-year loan at 16% APR with a 5% origination fee (a realistic offer for a borrower with fair, not good, credit).

Principal rolled in: 10,500 × 1.05 = $11,025. Payment at 16%/3 yrs ≈ $387/mo; total cost over the term ≈ $13,932 − $10,500 = ≈ $3,432. That's roughly $1,270 more than the ≈ $2,163 in interest the same borrower would have paid keeping the original cards (at their $325/mo pace, closer to 4 years — the fee plus the still-fairly-high 16% rate erase the benefit entirely). The lesson: a consolidation offer only helps if the rate is meaningfully below your blended card rate, not merely different from it.

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.

Consolidation loan vs. other options

OptionTypical rateBest for
0% balance transfer card0% for 12–21 mo, then 18%+Balances payable within the promo window
Personal consolidation loan8%–20%+ (credit-dependent)Fixed payoff date, meaningfully lower than card APRs
Home equity loan/HELOC7%–11%Homeowners with equity, comfortable using the house as collateral
Nonprofit debt management planOften reduced by the planCredit below ~600 or too much debt to qualify for a loan
No new loan (avalanche/snowball)Existing card ratesAnyone who wants zero risk of new-account fees or a hard inquiry

Common debt consolidation mistakes

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+.

Is a balance transfer card better than a consolidation loan?

A 0% promo card can beat a loan if you'll pay it off before the promo ends; riskier for balances that will still be around when the rate reverts to 18%+.

What happens if I miss a payment on the new loan?

Late fees and a credit-bureau report after 30 days, same as any installment loan — which defeats the purpose of consolidating in the first place.
