How It Works
Two repayment strategies dominate the conversation around getting out of debt, and this tool puts them side by side: the Debt Snowball and the Debt Avalanche. Comparing the two on your actual balances shows how each one shapes your timeline, the interest you'll pay, and how quickly you reach a zero balance.
The mechanics differ in which balance gets your attention. Snowball directs extra money at your smallest balance first; Avalanche targets the account carrying the highest interest rate. Under both, you keep making the minimum payment on every other account and funnel any spare cash toward the one debt at the front of the line until it's gone, then roll that freed-up payment to the next.
Results hinge on accurate inputs, so enter each interest rate and minimum payment carefully. Small errors compound and can throw off both the projected payoff date and the total interest figure. The other half of success is staying with whichever method you pick. Switching strategies midway, or skipping months, erases much of the advantage the numbers promise.
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.
- 3 With these inputs the avalanche is debt-free in 56 months with $9,029 of total interest, against 59 months and $10,694 for the snowball, because the 20% card, the most expensive balance, is cleared first. Both runs spend the same $700 a month ($550 of minimums plus the $150 extra), rolling each paid-off minimum into the next debt.
- 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.
