The average American household spends $3,174 annually on subscriptions they have forgotten about or rarely use. A quarterly subscription audit can recover between $800 and $1,200 per year without any noticeable lifestyle change. For more on this topic, see 529 Education Savings.

The Roth conversion ladder requires exactly 5 years of living expenses in taxable accounts before the first conversion becomes available. Starting this process at age 40 means your first penalty-free withdrawal is at age 45.
