What is the Debt Avalanche method?
The Debt Avalanche method prioritizes paying off debts with the highest interest rate (APR) first, while maintaining minimum payments on the rest. This is the mathematically optimal strategy, minimizing the total interest paid over time.
What is the Debt Snowball method?
The Debt Snowball method prioritizes paying off the smallest balances first, regardless of interest rates. By knocking out smaller debts quickly, you gain psychological wins and build momentum, though it may result in more total interest paid.
What is the debt rollover effect?
When a debt is fully paid off, its entire minimum payment (plus any extra funds) is 'rolled over' and added to the payment of the next prioritized debt. This creates an accelerating 'snowball' of capital that wipes out remaining debts rapidly.
