Creating a budget sounds complex. It's not. Here's everything you need, in sequence, to have a working budget in under 60 minutes.
What you need before starting
- Last 3 months of bank statements
- Last 3 months of credit card statements
- Last 3 pay stubs (to calculate average take-home)
- List of all fixed monthly bills
Step 1: Calculate your real monthly income
Use take-home pay (after taxes, benefits, 401(k) contributions). If income varies: use average of last 3 months. If highly variable: use the lowest month as your baseline.
Step 2: List fixed expenses
These don't change month to month: rent/mortgage, car payment, insurance premiums, minimum debt payments, subscriptions. Total these first — they're non-negotiable.
Step 3: Calculate variable necessities from statements
Grocery average, gas average, utilities average. Look at 3 months; average them. Add 10% buffer for variability.
Step 4: What remains is your allocation choice
Income minus fixed expenses minus variable necessities = discretionary pool. Allocate deliberately: savings goal, restaurant budget, entertainment, clothing, gifts.
