Good debt vs bad debt: the decision in numbers
Good debt vs bad debt is a weak label. Assess the loan’s total cost, affordability, downside and realistic value before borrowing or repaying early. Use
Debt is not morally good or bad
The labels are shorthand, and often poor shorthand. A loan does not become safe merely because it funds education, a home or a business; nor is every consumer loan irrational. Evaluate the contract and the household it enters: total cost, affordability, risk, flexibility and the realistic value created.
Five tests are better than one label
First, purpose: does the purchase plausibly improve durable earning capacity, housing security or essential mobility? Second, price: compare APR and total amount payable, not just the instalment. Third, affordability: can minimums and essentials be paid after an income shock? Fourth, downside: is the rate variable, is collateral at risk, or is another person guaranteeing it? Fifth, alternatives: could waiting, buying less or using savings produce a safer result?
A €12,000 training loan can be destructive if the qualification has weak employment evidence and the payment consumes all spare cash. A €1,500 appliance loan can be defensible if the appliance is essential, the price is transparent and repayment fits comfortably. Purpose informs the decision; it does not settle it.
Compare with numbers
For €10,000 over four years, 7% implies a payment around €239.46 and total interest near €1,494, before fees. At 18%, payment is about €293.75 and interest about €4,100. The borrowed object may be identical, while the financing changes the decision dramatically. APR helps compare regulated disclosures, but read included costs, late-payment terms and any security.
Future value is uncertain. Do not justify a guaranteed 18% cost with an optimistic salary, house price or business forecast. Test a lower benefit and higher expense.
A practical classification
Call debt manageable only when the purpose is clear, all-in price is competitive, repayment fits without repeated borrowing, major risks are understood, and a cheaper alternative has been considered. Treat high-cost revolving balances, opaque fees and loans used to cover a persistent monthly deficit as urgent warning signs.
Before signing, read the standard pre-contractual information, compare multiple offers on equal terms and write down the exit plan. For existing debts, rank actual rates and balances in the debt payoff calculator. Replace moral labels with a decision you can audit.
Review an existing loan without shame
The original purpose no longer changes today's optimal action. Gather current balance, nominal rate, APR disclosure if available, required payment, remaining term and early-repayment terms. Ask whether the financed asset still protects income or essential living, but do not let sunk costs justify further borrowing. Compare the guaranteed saving from repayment with the need for accessible emergency cash and any more expensive balances. If a loan is unaffordable, contact the creditor before arrears rather than focusing on its label. Pick a dated next action: keep the schedule, refinance after a verified break-even, overpay, or seek hardship support.
