Payment_{target} = Payment_{extra} + Min_{target} + \sum_{k \in \text{Paid Off}} Min_kWhen debt k is fully liquidated, its minimum payment is not spent; it rolls entirely into the next targeted balance.

The Debt Snowball method prioritizes debts with the smallest balance first, regardless of interest rate. Once a debt is paid off, its payment rolls over into the next smallest. The Debt Avalanche method prioritizes the debt with the highest APR first, mathematically saving the most money in interest charges over time.
Mathematically, the Avalanche method always saves the most money and eliminates debt in the shortest time. However, behavioral finance research shows that the Snowball method has higher real-world completion rates because quick psychological wins build powerful momentum and discipline.
Credit card minimum payments are typically calculated as 1% to 2% of the principal plus monthly interest. Making only minimum payments stretches debt repayment over 15 to 30 years and causes total interest payments to frequently exceed the original principal borrowed.
Yes. Consolidating high-APR cards (20%–30%) into a 0% introductory APR balance transfer card (usually 12–21 months with a 3–5% transfer fee) allows all monthly payments to attack principal directly, drastically accelerating the payoff timeline.
