# 50/30/20 rule

A simple budget split of after-tax income: about 50% to needs, 30% to wants, and 20% to savings and debt payoff.

The 50/30/20 rule divides take-home pay into three buckets. Needs, the things you must pay to keep life running, get 50%: housing, utilities, groceries, insurance, minimum debt payments, basic transportation. Wants get 30%: dining out, travel, subscriptions, hobbies, upgrades. Savings and extra debt payments get 20%: retirement, emergency fund, goals, and anything above the minimum on loans.

On $6,000 of monthly take-home, that is $3,000 for needs, $1,800 for wants, and $1,200 for savings. The rule is popular because it takes thirty seconds to apply and gives an honest first look at whether spending is in proportion. If needs are eating 70%, the problem is housing or debt, not lattes. If savings is at 5%, the gap is in the wants bucket.

It is a rule of thumb, not a target for everyone. In expensive cities, needs often run 60% or more. High earners aiming for early retirement may push savings to 40% or 50%. Someone with a 401(k) contribution coming out before take-home is already saving some of the 20% before the split.

The common mistake is misfiling. A $900 car payment on a car chosen for its looks is not entirely a need; a $200 grocery bill is not entirely a want because it includes steak. Being honest about the boundaries is most of the work. The second mistake is treating 20% as a ceiling for savings instead of a floor.
