How It Works
This calculator helps you compare two popular debt payoff strategies: the Debt Snowball and the Debt Avalanche. Understanding these methods is crucial for efficiently eliminating debt, saving money on interest, and achieving financial freedom faster.
The Debt Snowball method prioritizes paying off the smallest debt first, while the Debt Avalanche method prioritizes paying off the debt with the highest interest rate first. Both methods involve paying the minimum on all other debts and applying any extra funds to the prioritized debt until it's paid off.
A common mistake is not staying consistent with your chosen method; discipline is key. Also, ensure you accurately input all your debt details, including interest rates and minimum payments, as even small errors can significantly impact the projected payoff time and total interest paid.
Example: $30,000 in Debt
- 1 Input your debts: a credit card with $10,000 at 20% APR (minimum payment $200), a personal loan with $15,000 at 10% APR (minimum payment $250), and a car loan with $5,000 at 5% APR (minimum payment $100). You have an extra $150 per month to apply to your debt.
- 2 The calculator will run two simulations: one using the Debt Snowball and another using the Debt Avalanche. It will allocate the extra $150 to the smallest debt first (car loan) for snowball, or to the highest interest debt (credit card) for avalanche, and re-calculate minimums as debts are paid off.
- 3 The Debt Snowball might show a payoff in 40 months with $3,500 in interest paid. The Debt Avalanche might show a payoff in 36 months with $2,800 in interest paid. These numbers will vary based on initial inputs.
- 4 The result will clearly show which method saves you more money on interest and which gets you debt-free faster. While the avalanche saves more money, the snowball often provides quicker psychological wins, helping maintain motivation.
