Debt Snowball Calculator
The debt snowball method pays off your smallest balance first, then rolls that payment into the next — building momentum with every account you eliminate. Enter all your debts below to see your personalized payoff order, months to debt-free, and how much interest you save vs. making minimums only.
How the Debt Snowball Method Works
The snowball is a three-step loop that repeats until you are debt-free. Each month, you pay the minimum on every debt except the target — the smallest balance. Any extra money goes entirely to that target. When it reaches zero, its minimum payment gets added to your monthly attack payment for the next target. The "snowball" grows with each payoff.
Example with $23,400 total debt across 4 accounts and $150/mo extra: Month 4 — medical bill ($1,800) gone, $60 freed. Month 11 — store card ($3,400) gone, $68 more freed. Month 25 — credit card ($7,200) gone, $144 more freed. Final attack on personal loan ($11,000) uses $532 + $150 = $682/mo — 2.6× the original minimum. Done in 42 months.
❄️ Snowball Strategy: The Quick Win Rule
If you have any debt under $1,000, treat it as a sprint — not a marathon. A $600 medical bill at 0% APR still deserves to be first. Eliminating it in 2–3 months removes a creditor from your life and puts that minimum payment to work faster. The emotional momentum from your first payoff is worth more than the marginal math of targeting a slightly higher interest rate. Many people report that their first snowball payoff was the turning point where debt repayment went from a burden to a game they were winning.

Debt Snowball FAQ
How do I find extra money for the snowball?
Even $50–$100/month makes a material difference. Common sources: pause retirement contributions above the employer match temporarily (Dave Ramsey's Baby Steps approach), sell unused items, pick up a side gig for 6–12 months, negotiate one bill down (insurance, phone, internet), or use any windfall (tax refund, bonus, gift money) as a lump-sum payment on the smallest debt. The key is to direct every freed dollar to the target debt immediately — don't let it dissolve into general spending.
Should I stop investing while doing the snowball?
Dave Ramsey recommends pausing all investing except to get a 401(k) employer match (Baby Step 2). The math: if you have credit card debt at 22% APR, "investing" that money in the market at an expected 7–10% return is a guaranteed loss of 12–15% annually. However, if your debt is lower-rate (student loans at 5%, car at 4%), the comparison is closer and many financial advisors recommend doing both simultaneously. This calculator helps you see exactly how much faster your payoff accelerates with different extra payment amounts — so you can decide what tradeoff works for your situation.
What if I get more income partway through?
Any income increase should be directed entirely to your current snowball target — at least temporarily. If you get a $500/mo raise and your target debt has a $1,200 balance, you could eliminate it in 2–3 months instead of 6. Use this calculator's Scenario A vs. B feature to model what happens if you increase your extra payment at different points. The math heavily rewards front-loading extra payments: an extra $300 in month 1 saves more interest than $300 in month 18, because that $300 compounds against you until it's repaid.
Is the debt snowball the same as Dave Ramsey's Baby Steps?
The debt snowball is Baby Step 2 in Dave Ramsey's 7 Baby Steps framework. Baby Step 1 is saving a $1,000 starter emergency fund first. Baby Step 2 uses the snowball to eliminate all non-mortgage debt. Baby Step 3 builds a full 3–6 month emergency fund. Steps 4–7 cover investing, college funding, paying off the mortgage, and building wealth. This calculator focuses on Baby Step 2 — the snowball itself. You don't need to follow the entire Ramsey framework to benefit from the snowball method.
