Budget

A spending plan that tracks income and expenses to ensure you're living within your means and working toward financial goals.

Also known as: budgeting, spending plan, financial plan

What You Need to Know

A budget is your money's roadmap—it tells every dollar where to go instead of wondering where it went.

The Basic Formula: Income

Expenses = What's Left (savings/debt payoff/investments)

Popular Budgeting Methods:

50/30/20 Rule (simple):

50% Needs (housing, food, utilities, insurance)
30% Wants (dining out, entertainment, hobbies)
20% Savings (emergency fund, retirement, debt payoff)

Zero-Based Budget (detailed):

Every dollar gets assigned a job
Income
Expenses = $0 (all money is "spent" on paper, including savings)
Popular with YNAB (You Need A Budget) app

Pay Yourself First:

Save/invest first (automate it)
Live on what's left
Forces discipline

Why Most Budgets Fail:

Too restrictive (no fun money = burnout)
Not tracking regularly (guessing doesn't work)
No emergency buffer (unexpected costs derail everything)
Forgetting irregular expenses (car insurance, gifts, vacations)

How to Make It Work:

Track spending for 1 month (see where money actually goes)
Set realistic categories (don't lowball—be honest)
Include "fun money" (guilt-free spending = sustainability)
Review monthly and adjust
Use automation (auto-transfer to savings, auto-pay bills)

The Bottom Line: You don't need a perfect budget—you need one you'll actually follow. Start simple (50/30/20), track for one month, then optimize. The goal isn't restriction; it's awareness and alignment with your priorities.
