Refinancing debt: when does it pay off?

Refinancing always sounds sensible, but it is only a good idea under specific conditions. The basic idea is simple: you gather several expensive loans (typically credit cards and small loans) into one new loan with a lower effective interest rate, and save on interest costs. The catch is that it only works if the new rate is genuinely lower — and if you do not simply fill the old cards back up again.

Calculate the total cost, not the monthly payment. A lower monthly payment caused by a longer term can mean you pay more overall, even with a lower rate. Comparison services such as Savvy make it easier to gather several offers, but you have to compare effective interest and total repayment against what you have today yourself.

The critical trap is behaviour, not maths. Refinancing frees up credit limits; if you keep using them, you have doubled the debt instead of removing it. Refinancing should therefore be paired with a plan: cut up or freeze the old cards, and put the repayment into a personal budget. Without such a plan, refinancing is just a postponement, not a solution — the debt is moved, but it does not disappear.

To understand why the debt got expensive in the first place, read our guide to consumer loans. And the best protection against new expensive debt is an emergency fund that absorbs unexpected costs without a credit card.

Only refinance if the effective rate goes down and you have a concrete repayment plan. This is not financial advice — check the current terms carefully.
