Debt Consolidation And Why The Total Can Rise
Merging debts into one loan lowers the monthly payment by extending the term, which usually increases the total paid even when the interest rate falls.
Consolidation replaces several debts with one. The monthly payment nearly always falls, and the total amount repaid frequently rises, for reasons that are arithmetic rather than hidden.
The payment falls because the term extends
A monthly payment is a function of the amount, the rate and the term. Consolidation typically lengthens the term, which reduces the payment even at an unchanged rate.
Interest accrues for as long as the balance is outstanding, so a longer term means more periods of interest on money that is repaid more slowly.
A lower rate can offset this, but only if the term does not extend far enough to cancel the saving, which is where the comparison usually goes wrong.
Total cost is the comparable figure
Comparing the new monthly payment against the sum of the old ones answers a cash flow question, not a cost question.
The cost comparison is the total to be repaid under the new arrangement against the total that would have been repaid under the existing ones.
Lenders are generally required to disclose the total amount payable, which makes that comparison possible without any calculation by the borrower.
Fees and security change the picture further
Arrangement fees, broker fees and early settlement charges on the existing debts are part of the cost and are sometimes added to the new balance rather than paid upfront.
Where the new loan is secured on property, the interest rate is usually lower because the lender's risk is lower, and the borrower has converted unsecured debt into secured debt.
That conversion changes the consequence of non-payment rather than only the rate, which is a different question from whether the arrangement is cheaper.
The cleared accounts become available again
Consolidating card balances leaves those accounts open with zero balances unless they are closed, and the credit limits remain usable.
Where spending resumes on them, the household ends up with the consolidation loan plus new card balances, which is the common route to a larger total debt.
This is behavioural rather than structural, but it is frequent enough that closing or reducing the limits is usually discussed alongside the consolidation itself.
Cash flow relief can still be the right objective
None of this makes consolidation pointless. A household unable to meet current payments has a solvency problem now, and reducing the monthly obligation addresses it.
The distinction worth holding is between buying breathing room, which is what an extended term does, and reducing cost, which requires the rate saving to exceed the term effect.
Being clear about which objective applies makes the arrangement easier to evaluate, and free advice services can model both where the position is complicated.
