The Debt Snowball method, popularized by financial expert Dave Ramsey, is a debt reduction strategy that prioritizes paying off your smallest debts first, regardless of their interest rates. The core idea is to gain psychological wins and build momentum as you eliminate debts quickly, which helps you stay motivated on your journey to becoming debt-free.
How the Debt Snowball Calculator Works
This calculator helps you visualize your debt payoff journey using the snowball method. Here's the breakdown of the logic:
Debt Input: You'll list each of your debts, providing the current balance owed and the minimum monthly payment for each.
Additional Monthly Payment: This is the extra amount of money you can commit to paying towards your debts each month, above and beyond all the minimum payments.
The Snowball Process:
List your debts from smallest balance to largest balance.
Pay the minimum payment on all debts EXCEPT the smallest one.
On your smallest debt, pay its minimum payment PLUS the additional monthly payment you've committed to.
Once the smallest debt is paid off, take the total amount you were paying on it (its minimum payment + the additional payment) and add it to the minimum payment of the *next* smallest debt.
Continue this process, "snowballing" the amount you pay each month as each debt is eliminated, until all debts are paid off.
Calculation: The calculator simulates this process, showing you the estimated time to become debt-free and the total amount paid. It calculates the payoff timeline for each debt sequentially.
Why the Snowball Method is Effective
While mathematically, paying off high-interest debts first (the "debt avalanche" method) saves you more money on interest over time, the Debt Snowball method offers significant psychological benefits:
Motivation: Quickly paying off small debts provides a sense of accomplishment and encourages you to continue.
Momentum: Each paid-off debt builds momentum, making the larger debts seem more manageable.
Behavior Change: The focus on quick wins helps reinforce good financial habits and a debt-free mindset.
When to Use This Calculator
If you have multiple debts and struggle with motivation.
If you want a clear, step-by-step plan to get out of debt.
If you want to see the projected timeline and total cost of your debt payoff using Dave Ramsey's recommended strategy.
Remember, consistency is key. Every extra dollar paid towards your debt accelerates your journey to financial freedom!

// The core idea is that the payment for the *target* debt increases.
// Let's refine this: The total available payment is (Sum of all min payments + extra payment).
// This total payment is applied to the current smallest debt.
// The amount rolled over is what was paid on the previous debt that exceeded its min payment.
// Correct approach: The total monthly budget for debt is SUM(min_payments) + extra_payment
// This budget is applied to the current smallest debt.
// If currentTotalMonthlyPayment is less than the min payment for THIS debt + rolled over, this logic needs care.
// Let's re-think the snowball application:
// Total available cash for debt = SUM(all minimum payments) + additional_monthly_payment
// This total cash is applied to the current smallest debt until it's paid off.
// Reset for clarity:
// The amount paid on the current target debt is its minimum payment PLUS ALL previous minimums PLUS the extra payment.
// So, the actual amount paid to debts[currentDebtIndex] = debts[currentDebtIndex].originalMinPayment + (sum of originalMinPayments of debts 0 to currentDebtIndex-1) + monthlyExtraPayment
