Debt Consolidation: A Decision Framework

Consolidation changes structure, not the fact of debt

Combining balances can simplify administration and may lower an interest rate, but the principal still has to be repaid. If the new loan extends the term substantially, total interest may rise even when the payment falls.

Calculate the all-in cost

Include origination fees, balance-transfer fees, settlement charges and any promotional-rate expiry. Compare the remaining cost of current debts with the new loan over the same horizon. If a rate is variable, stress-test higher rates rather than assuming the opening rate lasts forever.

Behaviour after consolidation matters

If revolving balances are consolidated and then rebuilt, total debt can increase. A successful plan therefore needs a repayment schedule and a spending system that prevents the old balances from returning.

Securing previously unsecured debt changes consequences

Some consolidation products use a home or other asset as collateral. That can reduce the rate while increasing the consequences of non-payment. The risk change belongs in the decision, not just the payment saving.

Quality check for consolidation

Add every balance and fee before comparing the existing debts with the new facility. Preserve the original payoff path so the new payment is judged against the same starting debt rather than against an incomplete monthly snapshot. If the consolidation releases revolving credit capacity, model the plan on the assumption that old balances are not rebuilt; otherwise the comparison understates the behavioural risk.
