Debt Snowball Calculator

Use this calculator to estimate a debt payoff plan using the debt snowball method. This method pays minimums on every debt, then applies extra money to the smallest balance first to build momentum.

What this calculator does

The debt snowball calculator models up to five debts month by month.

It uses:

• debt balances
• interest rates
• minimum payments
• extra monthly payment

The result shows the estimated payoff order, months to become debt free, and total interest. It warns if payments do not cover monthly interest.

How to use the debt snowball calculator

Enter each debt balance, interest rate, and minimum payment. Add your extra monthly payment. The calculator targets the smallest balance first while continuing minimum payments on all other debts.

When one debt is paid off, its minimum payment rolls into the next smallest balance.

Debt Snowball Formula

Pay minimums on all debts, then apply extra payment to the smallest balance

Each month:

New balance = balance + interest - payment

Example calculation

If:

• Debt 1 = 1,000
• Debt 2 = 3,000
• Debt 3 = 6,000
• Extra payment = 200

Then:

The snowball targets the 1,000 balance first

After that debt is paid, its payment is rolled into the next smallest debt.

What is the debt snowball method?

The debt snowball method is a payoff strategy that prioritizes the smallest balance first, regardless of interest rate. It is designed to create quick wins and build motivation.

It may not minimize interest, but many people find it easier to follow.

Interpreting your result

The payoff order shows the sequence of debts. If interest savings matter more than motivation, compare with the debt avalanche method.

When to use this calculator

Use this calculator when you want to:

• build payoff momentum
• organize multiple debts
• test extra payments
• estimate debt-free timing

Common mistakes

Common mistakes include:

• skipping minimum payments
• not rolling payments forward
• ignoring unaffordable payments
• adding new debt during payoff
