Total Balance Projection over Time

How Calculations are Computed

Every month, the simulator performs these operations:

  1. Interest accrues on all active debt accounts: Interest = Balance × (APR / 12).
  2. Required minimum payments are deducted from the monthly budget and applied to each debt.
  3. Any leftover budget is focused entirely on the **Target Debt**:
    • Snowball target: The debt with the smallest balance (psychological prioritization).
    • Avalanche target: The debt with the highest APR interest rate (mathematical prioritization).
  4. When the target debt is fully paid off, its minimum payment rolls over to the next target.

Choosing Your Debt Payoff Strategy

Eliminating multiple consumer debts requires discipline and a proven strategic framework. The two most effective debt elimination strategies are the Debt Snowball and the Debt Avalanche methods.

Snowball vs. Avalanche Methodology

The Debt Snowball method prioritizes paying off debts from smallest balance to largest, regardless of interest rates, generating psychological momentum through early wins. The Debt Avalanche method targets debts from highest interest rate to lowest, mathematically minimizing total interest costs and accelerating payoff time.

The Debt Rollover Mechanism

Target Payment = Minimum Due + Discretionary Cash + Rolled-Over Payments

You maintain minimum payments across all active debts while funneling all surplus cash into the primary target debt. When that debt is eradicated, its entire monthly budget rolls into the next debt on your prioritized roster.

Keys to Successful Debt Elimination

  • Automate All MinimumsSet all non-targeted debts to autopay their minimums to protect your credit score from late fees and interest penalties.
  • Stop New Debt AccumulationTemporarily pause using credit cards while paying down balances to prevent neutralizing your repayment progress.
  • Consider Hybrid ApproachesPay off 1 or 2 small debts first for quick motivation, then switch to high-interest debts for mathematical efficiency.

Frequently Asked Questions

What is the Debt Snowball method?

The Debt Snowball method involves paying off your smallest debt balances first, regardless of interest rates. It builds psychological momentum and motivation through quick wins.

What is the Debt Avalanche method?

The Debt Avalanche method involves paying off your highest interest rate debts first. Mathematically, this minimizes the total interest you pay and helps you become debt-free faster.

Which method is better: Debt Snowball or Debt Avalanche?

Mathematically, the Debt Avalanche method is superior because it minimizes the total interest paid. However, studies show that the Debt Snowball method is often more successful in practice because the psychological momentum of clearing individual accounts quickly helps people stay motivated and stick to their plan.

How does the 'extra payment' roll over in these strategies?

In both methods, you continue paying the minimum required payments on all your debts. Any extra cash you can afford is added to the payment of your target debt (either the smallest balance or highest interest). Once that target debt is fully paid off, you roll its entire monthly payment (minimum + the extra cash) into the next debt on your list.

Can I do a hybrid of Snowball and Avalanche?

Yes. Some people prefer to pay off one or two small debts first to get immediate visual progress and free up cash flow (Snowball), and then pivot to targeting the remaining debts by highest interest rate to save on interest costs (Avalanche).
