Debt Consolidation: When Combining Debts Actually Saves Money
Rolling several debts into one loan is appealing — one payment, one due date — but it only saves money under the right conditions. Here's how to check before you apply.
The benchmark: your weighted average rate
A new consolidation loan is only a clear win if its rate, after accounting for any origination fee rolled into the balance, beats the weighted average rate of what you're replacing.
| Debt | Balance | APR |
|---|---|---|
| Credit Card 1 | $6,000 | 24.9% |
| Credit Card 2 | $3,500 | 21.9% |
| Personal Loan | $4,500 | 12.5% |
Weighted across $14,000 total, the blended rate here is about 20.6% — a consolidation loan at 11.5% comfortably beats it.
Watch the term, not just the rate
A 48-month loan at 11.5% might lower your monthly payment significantly compared to paying credit card minimums — but check the total interest figure too. If a lender stretches your consolidation loan out unnecessarily long, you can end up paying more in total interest even at a lower rate.
Frequently asked questions
What's a 'weighted average' interest rate, and why does it matter here?
It's the average APR across all your debts, weighted by balance — a $9,000 balance at 25% APR counts more than a $1,000 balance at 10% APR. It's the real benchmark a consolidation loan needs to beat, not just the highest or lowest individual rate.
Does a lower monthly payment mean I'm saving money?
Not necessarily — stretching the same balance over a longer term lowers the monthly payment but can increase total interest paid, even at a lower rate. Always compare total interest cost, not just the monthly number.
What if I can't qualify for a low enough rate to make consolidation worth it?
If the new loan's rate (after any origination fee) isn't meaningfully below your weighted average, consolidation mainly offers convenience (one payment) rather than savings. In that case, a structured payoff plan (avalanche or snowball) on your existing debts may serve you better.
Are balance transfer cards better than a personal loan for consolidation?
A 0% intro APR balance transfer card can beat any personal loan rate — but only for the promotional period (commonly 12–21 months), and only if you can realistically pay off the balance before it ends and reverts to a high standard rate.
