Budget
A budget is a plan that allocates expected income to expenses, savings, and investments over a set period. It is the foundational tool of personal finance — you cannot consistently save or invest without knowing where your money goes.
Common budgeting frameworks include the 50/30/20 rule (50% needs, 30% wants, 20% savings/debt), zero-based budgeting (every dollar assigned a purpose), and the envelope method (allocating cash to categories).
The most effective budget is the one you actually use. Tracking spending for 90 days typically reveals that actual spending in discretionary categories is 20–40% higher than people estimate.
