Compare your current debts to a single consolidation loan — the new payment, and how much interest (and time) you'd save.
Consolidation helps only if the new rate (and discipline not to re-borrow) beats your current path. Origination fees and a longer term can erase the savings. General information, not advice.
Rolling several high-rate debts into one lower-rate loan cuts interest — but only if you don't run the old balances back up, and if fees and a longer term don't outweigh the lower rate. This compares the interest both ways.
New payment = balance × r ÷ (1 − (1+r)⁻ⁿ); compare total interest vs. your current path
A lower monthly payment over a longer term can mean more total interest. And freeing up cards tempts new spending — the biggest reason consolidation backfires.
A 0% balance-transfer card can beat a loan if you clear it before the promo ends; otherwise a fixed loan gives a predictable payoff.
