What is the 10 year rule for a 401k?

The 401(k) 10-Year Rule, enacted by the SECURE Act, generally requires most non-spouse beneficiaries to withdraw the entire inherited 401(k) balance by the end of the 10th year after the original owner's death, replacing the old "stretch" option. If the owner already started Required Minimum Distributions (RMDs), the beneficiary must take annual RMDs for the first nine years, emptying the account by year ten; otherwise, the full balance must be gone by year ten, with all withdrawals taxed as ordinary income. Exceptions exist for eligible designated beneficiaries like spouses, minor children, disabled persons, or those not more than 10 years younger, who can still use life expectancy payouts.

For example, if you earn $100k, you'd aim for $100k at 30, $300k at 40, and $1 million by 50. These are guidelines, so saving 15% of your income annually (including employer match) is a good goal, with catch-up contributions available in your 50s.
