This debt snowball calculator builds a payoff plan for all your debts. List each balance, APR and minimum payment, add the extra amount you can pay each month, and choose the snowball method (smallest balance first) or the avalanche method (highest rate first). It shows your debt-free date, total interest, the order in which each debt is cleared, and how the other method compares.

What is a Debt Snowball Calculator?
The debt snowball is a payoff plan where you pay the minimum on every debt and put every extra dollar toward the smallest balance. When that debt is gone, its payment rolls into the next smallest, so the amount you put toward debt keeps growing like a snowball rolling downhill.
The debt avalanche uses the same rollover idea but targets the highest interest rate first, which usually saves more interest. The snowball gives faster early wins, which helps many people stick with the plan. This debt snowball calculator runs both, so you can see the real difference for your debts.
How does the Debt Snowball Calculator work?
Each month the calculator adds interest to every balance, pays each debt’s minimum, then puts the remaining budget (your extra payment plus any freed-up minimums) on the target debt in snowball or avalanche order. It repeats until every balance is zero and records the month each debt is cleared.

Debt Snowball Calculator FAQs
How does the debt snowball work?
Pay minimums on everything and put extra money on the smallest balance. When it is paid off, roll its payment into the next smallest.
Snowball or avalanche: which is better?
Avalanche usually saves more interest; snowball gives quicker wins. The calculator shows the difference for your debts.
Should I include my mortgage?
Most people leave the mortgage out and focus on consumer debts first.
What if a minimum payment is less than the interest?
That debt will grow until it becomes the target. Increase the extra payment if the plan does not finish.
Can I add debts later?
Yes. Add a row and the plan updates instantly.
Does the snowball hurt my credit?
No. Paying debts on time and lowering balances generally helps your credit.
