Snowball vs. Avalanche Comparison
Avalanche saves more money by targeting high-interest debt first. Snowball builds momentum by clearing small balances quickly for psychological wins.
How the Debt Payoff Calculator Works
This calculator runs month-by-month simulations of two popular debt payoff strategies: the snowball method (paying off smallest balances first) and the avalanche method (paying off highest interest rates first). It compares total months and interest paid so you can choose the strategy that fits your goals.
Snowball vs. Avalanche: Which Strategy Wins?
Debt Snowball
The snowball method prioritizes debts by balance size, paying off the smallest first. This creates quick wins and psychological momentum, which research shows improves adherence. You pay more interest overall but stay motivated longer.
Debt Avalanche
The avalanche method prioritizes debts by interest rate, paying off the highest rate first. This is mathematically optimal — it minimizes total interest paid and shortens the payoff timeline. The trade-off is that visible progress may feel slower early on.
