Zero-based budgeting (ZBB) means your income minus your expenses equals zero—every dollar has a job! Here’s how to use it!

Here’s everything about zero-based budgeting.

What Is Zero-Based Budgeting?

Zero-based budgeting is when you assign every dollar of your after-tax income to a specific expense, savings category, or debt payment—by the end of the month, your income minus expenses equals zero.

Example: Income $4,000 → $4,000 assigned to expenses/savings → $0 left unassigned.

How to Make a Zero-Based Budget

Follow these 5 steps!

Step 1: Calculate Your Monthly After-Tax Income

Start with your take-home pay—after taxes, 401(k), health insurance, etc. If you have irregular income, use your average monthly income or your lowest monthly income (conservative!).

Step 2: List All Your Expenses

Break expenses into categories:

  • Fixed expenses (same each month): Rent/mortgage, car payment, insurance.
  • Variable expenses (change each month): Groceries, gas, utilities, dining out.
  • Irregular expenses (annual/quarterly): Car registration, gifts, annual subscriptions—divide by 12 and save monthly.
  • Savings: Emergency fund, retirement, sinking funds.
  • Debt: Minimum payments + extra payments.

Step 3: Assign Every Dollar a Job

Make sure your total assigned dollars equal your income—zero out!

  • Use a spreadsheet (Google Sheets, Excel) or budgeting app (YNAB, Mint, EveryDollar).
  • If you have extra money, assign it to savings, extra debt, or a fun category!
  • If you’re short, cut expenses or increase income!

Step 4: Track Your Spending Throughout the Month

Check in weekly to make sure you’re staying on track!

  • Use an app to sync your bank accounts.
  • Log expenses manually if you prefer.

Step 5: Adjust as Needed and Roll Over Extra

  • At the end of the month, roll over extra money in a category to the next month (or put it toward extra debt/savings!).
  • Adjust next month’s budget based on what you spent!

Pros of Zero-Based Budgeting

  • Full control: You know exactly where every dollar goes.
  • Good for irregular income: Assign dollars based on expected income.
  • Helps find extra money: You’ll see where you’re overspending!

Cons of Zero-Based Budgeting

  • Time-consuming: You have to track every dollar—good for detail-oriented people.
  • Can be restrictive: Less flexible than 50/30/20.

Common Mistakes to Avoid

  • Forgetting irregular expenses: Use sinking funds to save monthly for annual costs!
  • Not budgeting to zero: Leftover money should have a job too!
  • Being too hard on yourself: It’s okay if you go over in one category—adjust the next month!
