Payoffmydebtcalculator.com compares the snowball and avalanche debt payoff strategies side by side using your actual debts and extra monthly payment amount, showing exactly which method saves more money and when the two strategies cross over.
The snowball-vs-avalanche debate usually gets argued in the abstract — psychology versus math — but the honest answer depends entirely on your specific numbers. We built this so you can see your own crossover point instead of picking a strategy based on a blog post about someone else's debt.
