About this routine

The David Bach debt avalanche strategy structures consumer debt payoff around mathematical efficiency. By targeting the balance with the highest annual percentage rate first, you minimize total interest paid over time. This 35-minute planning session guides you through inventorying liabilities, calculating daily discretionary savings, and automating monthly payments.

In the first 15 minutes, you list all debts alongside their interest rates and calculate surplus cash identified through small daily spending adjustments. The remaining 20 minutes focus on directing all available surplus toward the highest rate balance, calling issuers to negotiate lower interest rates, and setting up automatic recurring payments.

Automating this process removes emotion and monthly friction from debt repayment. Once the highest rate debt reaches zero, the full payment rolls automatically into the next highest rate balance on the ladder.

Why this routine works

Reduces overall interest expense by prioritizing high APR accounts
Creates a clear order of payoff without constant monthly manual decisions
Frees up surplus cash through small daily habit adjustments
Removes execution friction by automating payment schedules
