Expert Tip

The Debt Snowball method prioritizes paying off small debts first to gain mental victories, despite the interest rates.

How this Calculator Works

This calculator designs a debt payoff plan using the snowball method. By focusing on paying off the smallest balances first while maintaining minimum payments on larger debts, it builds psychological momentum to help you get out of debt.

Formula & Methodology

Sorts debts by outstanding balance size from smallest to largest. Allocates extra monthly payments to the smallest debt until paid, then rolls over the payment.

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

You have Debt A ($500 balance, $50 min) and Debt B ($2,000 balance, $80 min). You budget an extra $100 monthly. 1. Focus extra money on Debt A: Pay $50 + $100 = $150/month until paid (takes 4 months). 2. Roll over payment to Debt B: Pay $80 + $150 = $230/month. Result: Using this momentum, you accelerate the clearance of both debts.

FAQ

What is the 4% rule in FIRE (Financial Independence) planning?
Derived from the Trinity Study, the 4% rule suggests withdrawing 4% of your total investment portfolio in year one of retirement (adjusted for inflation thereafter) provides a 95%+ probability of portfolio survival over 30 years.
What is the difference between Debt Snowball and Debt Avalanche?
Debt Snowball pays off debts from smallest balance to largest balance first for psychological momentum. Debt Avalanche pays off debts from highest interest rate (APR) to lowest to minimize total interest paid.
How much emergency fund reserve is recommended?
Financial planners recommend storing 3 to 6 months of essential living expenses (rent/mortgage, groceries, utilities, debt minimums) in a high-yield liquid savings account (HYSA).
