How It Works

Debt Payoff Snowball vs. Avalanche Calculations: Both methods calculate monthly payments by ensuring the minimum payment is made on every active debt. The difference lies in how extra monthly payments (the "snowball budget") are directed: 1. Debt Snowball Method: - Sort debts by principal balance in ascending order (smallest to largest). - Direct all extra budget to the smallest debt until it is fully paid. - Roll that debt's entire minimum payment and the extra budget into the next smallest debt. - Advantage: Psychological momentum from quick early wins. 2. Debt Avalanche Method: - Sort debts by interest rate (APR) in descending order (highest to lowest). - Direct all extra budget to the highest-interest debt. - Roll payment capacities forward as debts are paid off. - Advantage: Mathematically optimal, resulting in the lowest possible total interest paid.

Frequently Asked Questions

Which is better: Debt Snowball or Debt Avalanche?▼

Mathematically, the Debt Avalanche is always better because it targets the highest interest rates first, saving you the most money in interest charges. However, studies show that the Debt Snowball is highly successful in practice because the psychological boost of paying off small debts quickly builds habit and motivation.

Why must I pay the minimum payment on all debts first?▼

Failing to pay the minimum monthly payment on any active debt results in late fees, penalty interest rate hikes, and severe damage to your credit score. The calculator automatically allocates minimum payments first to ensure account standing before deploying extra budget.

Can I add a one-time extra payment to my debt payoff timeline?▼

Yes. Allocating tax returns, bonuses, or cash gifts as one-time payments directly reduces outstanding principal, saving interest and shortening your debt-free timeline.

Does paying off debt yield a guaranteed return?▼

Yes. Paying off a debt with a 15% APR is mathematically equivalent to earning a guaranteed 15% tax-free return on your investment, as it prevents those interest charges from compounding against you.
