All tools

Supercharging the Avalanche Strategy

Applying extra monthly cash directly to your highest-interest account accelerates total debt payoff and maximizes interest savings.

Frequently Asked Questions

Can windfalls (bonuses, tax refunds) be added to the avalanche?

Yes. Lumping one-time cash inflows onto the highest-rate debt produces immediate compounding relief.

What should you do after the highest interest debt is cleared?

Roll its entire monthly payment allocation over to the next highest-APR debt on your list.

Does this prevent interest capitalization?

Yes. Larger principal reductions prevent unpaid interest from adding to subsequent billing balances.

How does early debt freedom impact emergency savings?

Clearing high-cost debt allows you to redirect regular monthly payments into building an emergency fund.
