Debt consolidation pros and cons

The trap, in numbers

Say $18,000 of card debt at 22%, which you are clearing with $470 a month over about 4 years. A consolidation loan at 12% over 5 years drops the payment to roughly $400. At 12% over 7 years it drops to about $318.

The rate nearly halved in every consolidation row, and total interest went up in both. A lower rate over a longer term is not automatically cheaper, and the lower the monthly payment looks, the more likely that is.

When it genuinely works

The rate drops and the term does not stretch. Same payoff horizon, lower rate: unambiguously better.

You keep paying the old amount. Take the 12% loan, keep paying $470 rather than the required $400, and you clear it faster than either scenario above while paying far less interest. Consolidation gives you the lower rate; discipline captures the benefit.

One payment prevents missed ones. If juggling six due dates is producing late fees and rate penalties, simplification has real value beyond arithmetic.

When it backfires

Origination fees. A 5% fee on $18,000 is $900, either deducted from what you receive or added to what you owe. That can erase a rate advantage on its own.

The cards get used again. Consolidation clears the balances but leaves the accounts open. Running them back up leaves you with the loan and the cards, a materially worse position than before.

Unsecured debt becomes secured. Consolidating into a home equity loan usually buys a much lower rate, but it moves the risk onto your house. Card debt cannot repossess anything.

The test worth applying

Compare total cost to clear, not monthly payment. If the consolidation total exceeds what you are on track to pay now, the lower payment is buying time rather than saving money — which is occasionally the right call, but should be a decision made deliberately.

Compare both paths

The debt consolidation calculator puts the current path and the consolidation loan side by side on total cost and timeline. The loan comparison calculator helps when several consolidation offers are on the table.

When consolidation actually helps

Consolidation changes rate and term, not principal. Whether it helps depends on both, and on whether the cleared cards stay cleared.

The third row is a legitimate trade if the lower payment is what makes the plan survivable. The fourth row is why consolidation has a mixed reputation, and it is a behavioural failure rather than a product one.
