Most first budgets fail because they start with fifty categories and a guilt spiral. A workable first pass needs only take-home income, needs, wants, and planned savings—then a clear remaining balance.

Use the amount that lands in your account after tax and mandatory withholdings. If pay varies, average the last three months or budget from the lower month until you have a buffer.

Needs keep the lights on and you employed. Wants are flexible. Misclassification is common—be honest, then adjust. A separate needs-vs-wants article walks the gray area.

If savings is “whatever is left,” it is usually zero. Pick a starter amount toward an emergency fund or a named goal, even if small.

After the cash worksheet, optionally check a 50/30/20 target. If needs blow past 50%, that is information—not a moral failure. Trim wants next, then revisit larger fixed costs.
