Debt Consolidation
Combining five payments into one doesn’t make the debt smaller — it just changes its shape, for better or worse depending on the new rate.
What Is It
Debt consolidation means combining multiple debts — credit cards, personal loans, or a mix — into a single new loan, ideally at a lower interest rate, with one monthly payment instead of several.
Why It Matters
Consolidation restructures debt, it doesn't reduce it. The real savings depend entirely on whether the new loan actually carries a lower effective rate than the weighted average of what it's replacing — not just on whether the new monthly payment feels smaller. A smaller payment achieved by stretching the term out longer can mean paying more in total interest even at a genuinely lower rate, which is exactly the same tradeoff already covered in Loan Term Tradeoffs — the math doesn't change just because multiple debts got folded into one.
Quick Example
$15,000 spread across credit cards averaging 22% APR gets consolidated into a single personal loan at 12% APR. Kept to the same 4-year timeline, the lower rate alone saves roughly $3,724 in total interest ($7,684 versus $3,960). But stretch that same 12% loan out to 7 years instead, to shrink the monthly payment further, and total interest climbs back up to about $7,242 — nearly erasing the benefit the lower rate was supposed to deliver.

Sources & Methodology
- The principle that consolidation restructures rather than reduces debt, and that real savings depend on the effective rate rather than the payment size, reflects general attribution across consumer-lending guides — not a single pinpoint source.
- Term-extension math (lower payment, more total interest at a longer term) verified programmatically using the same closed-form amortization formula used throughout this category; see Loan Term Tradeoffs for the full breakdown rather than re-deriving it here.
