Build a Simple Monthly Budget in 15 Minutes

The key insight: Most budgets fail because they're too complex. Track 4 categories max: Fixed Bills, Variable Spending, Savings, Everything Else.

The 50/30/20 Framework

Split your after-tax income:

• 50% Needs — rent, utilities, groceries, insurance, minimum debt payments
• 30% Wants — dining out, subscriptions, hobbies, shopping
• 20% Savings — emergency fund, retirement, debt paydown above minimums

Step-by-Step Setup (15 minutes)

1. List your monthly take-home pay (after taxes and deductions)
2. List fixed bills — rent/mortgage, car payment, phone, internet, insurance. Add them up.
3. Track variable spending for 1 month — use your bank's transaction history. Groceries, gas, restaurants, subscriptions.
4. Set savings goal — 20% of take-home, or whatever you can sustain. Automate it.
5. Budget the rest — what's left after needs + savings = guilt-free spending money.

Free Tools That Actually Work

• Spreadsheet — Google Sheets template (see products). Total control, zero learning curve.
• YNAB (You Need A Budget) — best for envelope budgeting, syncs with banks. $109/year after 34-day trial.
• Mint — free, auto-categorizes transactions, shows spending trends. Ads but functional.
• EveryDollar — Dave Ramsey's zero-based budget app. Free version is manual entry.

Common Mistakes

• Tracking every penny — unsustainable. Round to nearest $10.
• No buffer category — life happens. Budget $50-100/month for 'misc' so random expenses don't derail you.
• Forgetting annual expenses — car registration, Amazon Prime, holiday gifts. Divide by 12 and budget monthly.

Pro tip: Pay yourself first. Set up auto-transfer to savings the day after payday — treat savings like a non-negotiable bill. What you don't see, you don't spend.
