Debt avalanche example
This worked example shows how a highest-interest-first debt payoff plan may behave when a fixed extra payment is added to the monthly debt budget. This catch-up debt mix reflects a period of higher balances across cards and a personal loan, often after an unexpected expense. A moderate extra payment like this one can noticeably shorten the time before the highest-rate balance is cleared.
Calculated answer
The example debt stack totals $16,000 with $480 in minimum payments. Under the debt avalanche method, the suggested order starts with Travel Card, and the estimated payoff time is 25 months.
Minimum payments stay current while extra money attacks the highest interest rate first
The shared debt-avalanche math accrues monthly interest, pays required minimums, and sends remaining budget toward the highest-rate active debt.
| Balance | Interest rate | Minimum payment | |
|---|---|---|---|
| Travel Card | $2,400 | 28% | $85 |
| Medical Plan | $4,700 | 0% | $140 |
| Personal Loan | $8,900 | 14% | $255 |
The debt avalanche method is most useful when the main goal is reducing interest cost rather than clearing the smallest balance first.
Worked examples make that strategy easier to visualize by showing which debt becomes the first target and how a fixed debt budget gets reallocated over time.

Yes. If the combined monthly debt budget is too low to reduce balances after interest accrues, the payoff path may be unreachable under the current assumptions.
