Enter all your debts with balances, interest rates, and minimum payments. Add any extra monthly payment you can afford, and this calculator compares two popular payoff strategies: avalanche (highest APR first) and snowball (smallest balance first). See your debt-free date, total interest paid, and the optimal payoff order.

The debt avalanche method targets the debt with the highest interest rate first. Once that debt is paid off, its minimum payment is freed up and added to the next highest-rate debt. This approach minimizes total interest paid and is mathematically optimal. The debt snowball method targets the smallest balance first, giving you quicker psychological wins that help maintain motivation.
Your extra monthly payment is applied on top of all minimum payments. As each debt is eliminated, its minimum payment is "freed up" and cascades to the next debt in line. This snowball effect accelerates payoff dramatically — even a modest extra $200/month can save thousands in interest and cut years off your debt-free date.
With $48,000 in total debt across three accounts (credit card at 22.99%, car loan at 6.5%, student loan at 5%) and $300/month extra, the avalanche method typically saves $1,000–3,000 more in interest compared to snowball, though both strategies dramatically outperform making only minimum payments.
Avalanche (highest APR first) minimizes total interest and is mathematically optimal — with $48,000 across credit card (22.99%), car (6.5%), and student loan (5%), avalanche typically saves $1,000–3,000 more than snowball with $300/month extra. Snowball (smallest balance first) gives quicker wins and helps some people stay motivated. Use this calculator to compare both with your actual debts.
It depends on your balances, APRs, and extra payment. With $48,000 in total debt and $300/month extra, both avalanche and snowball save thousands in interest and cut years off your debt-free date compared to minimum payments only. High-APR debt (e.g. credit cards at 22–24%) costs the most — targeting it first with extra payments usually saves the most. Enter your debts in the calculator to see exact interest saved.
For the lowest total interest: pay minimums on all debts and put every extra dollar toward the debt with the highest APR (avalanche). For psychological momentum: pay off the smallest balance first, then roll that payment to the next (snowball). This calculator shows the exact order for both strategies and the interest difference so you can choose.
A $10,000 balance at 22.99% APR with a $250 minimum and $300 extra ($550 total) can be paid off in roughly 2–3 years instead of 5+ with minimum only — saving thousands in interest. Exact time depends on your balance, rate, minimum, and extra amount. Add your card to the calculator to see your debt-free date and total interest.
Yes. Snowball works by freeing up minimum payments as each debt is eliminated and applying that cash to the next debt, creating a cascading effect. It often pays off debt faster than minimum-only by hundreds or thousands of dollars. Avalanche usually saves slightly more in interest, but both strategies are far better than paying only minimums.
