Debt Snowball vs. Avalanche: Which Payoff Strategy Fits Your Plan?
Debt snowball and avalanche are two ways to direct extra money across multiple debts. Compare estimated interest and payoff time, then choose a plan you can sustain.

This guide explains a comparison framework and links to an interactive calculator. Results depend on the values and assumptions entered; they are not personalized financial advice.
How the debt snowball works
Keep making required minimums, then direct available extra money to the smallest balance. When it is paid, roll that freed payment into the next balance. Early account payoffs can make progress visible.
How the debt avalanche works
Keep minimums current and direct extra money to the debt with the highest APR. With rates and payment timing held constant, paying the costliest balance first generally reduces interest.
Compare more than interest
A model can estimate interest and payoff time, but it cannot decide which routine will be easiest to keep. Use a realistic monthly budget, avoid adding new balances where possible, and include a modest cushion for irregular expenses.
If payments are difficult
Contact creditors before missing payments to ask about available options. Be cautious of companies that promise guaranteed debt relief or ask you to stop paying creditors. The CFPB provides an overview of debt reduction methods and planning resources.
