Debt consolidation

Definition

Debt consolidation means replacing several debts with a single loan — often to simplify payments or change the rate. You might roll cards and a small loan into one personal loan, or move balances onto a new facility. The monthly payment can fall even when lifetime cost rises, especially if the new term is longer or an arrangement fee applies.

Consolidation is a product change, not a payoff order. Snowball and avalanche rearrange how you attack existing balances; consolidation replaces those balances with a new contract. Always check lifetime cost and fees, not only the new instalment.

Why consolidation matters for personal loans

UK borrowers are often offered consolidation as a way to “clear the cards”. The risk is familiar: a lower monthly figure looks like progress while a fee and a stretched term raise total interest, or a cheap balance is blended into a dearer rate. A careful break-even view asks when (if ever) the new loan costs less than keeping the old debts and paying them down with extras.

Consolidation also interacts with APR and true-cost reading. The new loan’s headline rate is not enough if cash in hand is reduced by fees or if early-settlement figures on the old debts change what you need to borrow.

Worked EXAMPLE — one loan vs three balances

All figures below are labelled EXAMPLE. They are illustrative only — not a live quote and not a credit offer.

Suppose the three-debt EXAMPLE set (£1,200 @ 29.9% / £3,400 @ 22% / £6,800 @ 9.9%) is replaced by a single personal loan in EXAMPLE Loan B style: £12,000 blended principal, 16.9% EXAMPLE, 60 months, £195 fee. The new monthly payment may look tidier than three separate minimums plus extras — but the fee and the longer term can still leave you paying more over the life of the loan than an avalanche path with £75 EXAMPLE extra on the separate balances.

That is exactly the comparison the consolidation break-even calculator is for. The guide consolidation break-even narrates the same idea in prose. Neither is a recommendation to apply.

How LoanCalc Lab uses it

LoanCalc Lab treats consolidation as a fee-aware break-even problem. Tools stay illustrative. If repayments already feel unmanageable, seek free debt advice rather than only modelling a new EXAMPLE loan.

Common mistakes

• Choosing the lowest monthly payment without checking lifetime interest.
• Forgetting arrangement fees or early-settlement costs on the debts you clear.
• Running up the old cards again after consolidating (double debt).
• Treating an on-site EXAMPLE as a credit offer or broker recommendation.
