When several debts pile up at once (cards, personal loans, financing for different purchases), debt consolidation is often presented as a miracle solution: one single, lower payment instead of several scattered ones. The reality is more nuanced, and in many cases the final result ends up costing more than keeping the debts separate.
What debt consolidation is
It involves taking out a new loan (usually secured by a mortgage if the amount is large, or a personal loan if it's more modest) whose proceeds are used to pay off all your previous debts, leaving you with a single monthly payment at a new term and interest rate, replacing the scattered payments you were making before.
Why the monthly payment goes down: the effect of a longer term
The main reason the resulting monthly payment tends to be lower is almost never that you get a much better interest rate on all your debts, but rather that you extend the total repayment term. By spreading the same (or similar) debt over more years, the monthly payment mathematically goes down, even though the total interest cost over the life of the loan can end up considerably higher than if you had kept the original debts with their original terms.
When it can genuinely make sense
- When you manage to replace very high-interest debts (revolving credit cards, fast loans) with a clearly lower interest rate on the consolidated loan, even accounting for the extended term.
- When your current monthly burden is unsustainable given your income situation, and the immediate priority is reducing the risk of widespread default, even if it means a higher total cost in exchange for short-term financial stability.
- When simplifying the management of multiple payments genuinely reduces the risk of missed payments that would trigger additional fees and penalties.
When it tends to be a trap
- When the interest rate on the consolidated loan isn't significantly better than your original debts, and the only real "benefit" is extending the term, which increases the total cost.
- When it's arranged in a hurry, without comparing the full APR of the consolidation loan against the weighted total of your current debts.
- When it involves putting up a mortgage guarantee (your home) to consolidate debts that originally had no real collateral attached, significantly increasing your risk exposure.
How to properly evaluate a consolidation offer
Before accepting, calculate the total cost (all the interest you'd pay) of keeping your current debts as they are, and compare it to the total cost of the proposed consolidation loan, not just the monthly payment. A lower monthly payment with a much higher total cost isn't, in financial terms, a real improvement in your situation.
