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?▼

With fixed rates, the same total payment budget, and no extra fees, prioritizing higher-interest balances can reduce interest costs. Prioritizing smaller balances can make progress easier to track. Actual outcomes depend on repayment behavior, changing rates, fees, and lender terms.

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?▼

Repaying debt can avoid future interest under the lender’s terms. It is not an investment payout, and the benefit depends on rates, fees, tax treatment, and whether you borrow again. This comparison does not model every personal circumstance.
