Which Debt Should You Pay First? Cost-First vs Smallest-Balance

Map every debt before ranking one

For each obligation, record the balance, stated APR or cost, minimum payment, due date, possible fees and any instructions for directing extra payments. Use a recent statement and product terms rather than memory.

If you cannot cover minimums or are already in arrears, an aggressive ordering method is not the first task. Contact the creditor early through an official channel and understand options and consequences before agreeing. Do not ignore a notice or claim.

• Protect minimum payments first.
• Separate disputed or legally escalated debts.
• Do not automatically borrow to fund the plan.
• Keep essential-expense resilience appropriate to your circumstances.

Method one: highest cost first

After all minimums, direct extra money to the debt with the highest interest rate or stated cost, then roll that payment to the next one after payoff. The CFPB explains that this removes the most expensive debt first and can give more value for each extra payment.

Its advantage is mathematical when inputs remain stable and extra payments are applied as instructed. Progress may feel slow when the costliest balance is large. Check prepayment fees and allocation rules rather than assuming.

Method two: smallest balance first

Pay every minimum and send the extra amount to the smallest balance, then roll the freed payment to the next. CFPB notes that reducing the number of debts can make progress visible, but total cost may be higher when expensive debts remain longer.

This is not universally best. Its practical value may be fewer bills and behavioural momentum. Compare that benefit with expected cost and write down your reason so the plan does not change every month.

Fictional example: one choice, two routes

A fictional household has three obligations after minimums are protected: SAR 1,200 with no periodic cost, SAR 4,000 at 8%, and SAR 9,000 at 18%. It has SAR 500 extra each month. Smallest-balance starts with SAR 1,200; cost-first starts with SAR 9,000.

We do not calculate a payoff date or savings because contracts differ in fees, allocation and compounding. The example isolates the choice: minimize expected cost or close one small obligation early. Use actual documents and an appropriate tool—or qualified help—before a major credit decision.

Write an execution and review rule

Choose one method for a fixed review window, such as three months, and record balances after each statement. When a debt closes, move the full freed payment to the next rather than letting it disappear into routine spending.

Review immediately if income, fees, arrears or legal demands change. A plan should not displace food, housing or necessary care. Responsible continuity matters more than an optimistic timetable.

• Pay every minimum on time.
• Direct the extra to one debt under the written rule.
• Confirm the payment was applied as instructed.
• Review balances and costs quarterly.
