How the Debt Snowball Method Works
The debt snowball method ranks your debts from smallest balance to largest. You make the minimum payment on every debt, then throw every extra dollar at the smallest one. When that debt is gone, you celebrate the win and roll its old minimum payment into the next-smallest debt. The payment "snowballs" — growing with each debt you clear — which is why this method is so good at building the momentum to stick with your plan.
How the Debt Avalanche Method Works
The debt avalanche method ranks your debts from highest interest rate to lowest. You still pay the minimum on everything, but your extra money attacks the most expensive debt first. Because high-interest balances stop growing fastest, the avalanche method saves the most money in total interest over the life of your debt. It takes more discipline than the snowball, but the math is on your side.
Snowball vs Avalanche: Which Should You Pick?
Both methods pay the minimum on all debts and apply extra money to a single target. The difference is the target: smallest balance (snowball) or highest APR (avalanche). The avalanche almost always wins on cost; the snowball wins on motivation. Many people use the avalanche to save money while keeping a snowball mindset by tracking quick wins. This planner shows both strategies side by side so you can see exactly how many months and how many dollars each one saves you.
Why Extra Payments Matter
Interest is charged every month on whatever balance remains. Any payment above the minimum goes straight to principal, so the next month's interest is calculated on a smaller balance. Just as important, when a debt is fully paid its minimum payment is freed up and added to your attack payment on the next debt. That rollover is why adding even $50–$100 a month can cut years off your debt-free date and save thousands in interest.

How to Plan Your Debt-Free Date (Step by Step)
- List each debt. Write down every balance you owe — credit cards, student loans, car loans, medical bills — with its current balance, interest rate (APR), and minimum monthly payment.
- Add an extra monthly payment. Decide how much extra you can put toward debt each month on top of your minimums. Even a small amount accelerates your debt-free date.
- Pick your strategy. Choose Snowball (smallest balance first) for quick wins, or Avalanche (highest APR first) to save the most interest. The planner calculates both automatically.
- Roll freed payments forward. Each time a debt is cleared, its minimum payment is added to your attack payment on the next debt, creating a snowball of momentum.
- Read your debt-free date. See your payoff date, total interest paid, and total cost for each method, then compare them side by side to choose your plan.
