This calculator compares the avalanche and snowball debt payoff methods, tailored to a specific scenario from a Reddit Money Diaries post. It provides a helpful illustration of how extra payments can accelerate a debt-free date. However, it doesn't have much over the original [Debt avalanche or snowball?](/heyfinfam/views/debt-avalanche-vs-snowball). Users should also be aware that because the author updated the default balances without adjusting the underlying formulas, the snowball method calculates out of order, which skews the final comparison.
