Frequently Asked Questions
- The Debt Avalanche method is mathematically optimal because targeting high-interest debt first minimizes total interest paid over time.
- The Debt Snowball method eliminates individual accounts quickly, providing immediate psychological rewards and reducing the total number of bills to manage.
- When one debt is fully paid off, its entire monthly payment is rolled over and added to the payment of the next priority debt on your list.
- Typically, consumer debts (credit cards, personal loans, auto loans) are prioritized first due to higher interest rates, while low-interest mortgages are handled separately.
- Even an extra $100 to $200 per month applied consistently can shave years off repayment timelines and save thousands in compounding interest.
- Debt Avalanche prioritizes paying off debts with the highest interest rate first to minimize total interest cost, whereas Debt Snowball prioritizes the smallest balance first for psychological momentum.
- When one debt is completely paid off, its monthly payment amount rolls over into the next target debt, exponentially increasing the principal repayment rate without increasing your overall budget.
