Zero-Based Budget: Free Worksheet, Worked Example and How It Works
A zero-based budget gives every dollar of your take-home pay a job before the month starts. You list your income, then assign all of it (bills, groceries, savings, debt payments, fun money) until income minus everything you have assigned equals zero. Zero does not mean spending everything: money for savings and extra debt payments is assigned too, so it cannot quietly disappear. The method takes more effort than a rule-of-thumb budget, and that is its point. Below is a worksheet you can fill in right on this page and download as a spreadsheet, then a step-by-step guide, a full example, and the average US household spending figures from the Bureau of Labor Statistics to check your numbers against.
The Short Answer
- The rule: take-home income − every planned dollar of spending, saving and debt payment = $0.
- Savings count as a line item. "Zero" means fully planned, not fully spent.
- Plan monthly, before the month starts, and adjust when something changes: move money between lines, never out of thin air.
- Include irregular costs as monthly "sinking funds" (car repairs, holidays, annual subscriptions), or they will break the budget.
- Best for: people who want tight control, are paying off debt, or keep wondering where the money went. A 50/30/20 split is simpler if you already save consistently.
Zero-Based Budget Worksheet
Type your monthly take-home pay, then change each line to your own amounts. Rename any line, delete the ones you do not need and add your own. The counter shows how much is still without a job; your budget is done when it reads $0 left. It starts filled in with the example household further down this page.
The download is a CSV file that opens in Excel, Google Sheets or Numbers. It has an "Actual spent" column and a difference column for each line, so the same file works as your tracking sheet during the month. Nothing you type is sent anywhere.
How It Works
Most budgets track what you spent last month. A zero-based budget decides what you will spend next month. The name comes from zero-based budgeting in organizations, where each period's budget is built from nothing rather than rolled forward from last year: every line has to justify itself again (more on that below).
Applied to a household, that means two things. Every category starts at zero each month and is filled deliberately. And the total assigned must equal your income exactly: if you assign less, the leftover is unplanned money that tends to leak away; if you assign more, you are budgeting money you do not have.
Build One in Six Steps
- Write down this month's take-home pay. Use what actually arrives in your account after tax, retirement deductions and health premiums. If income varies, use a conservative figure (see below).
- List fixed essentials. Rent or mortgage, utilities, insurance, phone, minimum debt payments, childcare.
- List variable essentials. Groceries, fuel and transport, medical costs. Use last month's bank and card statements, not guesses.
- Assign savings and extra debt payments. Treat them as bills. This is where an emergency fund, retirement saving and extra payments on high-rate debt go.
- Add sinking funds for anything that does not happen monthly: car maintenance, holidays, birthdays, annual subscriptions, insurance paid once a year. Divide the yearly cost by 12.
- Assign what is left to wants (dining out, entertainment, hobbies) and a small buffer, until you reach exactly zero. If you run out before the essentials are covered, go back and cut.
A Worked Example
Hypothetical household with $5,500 a month of take-home pay after payroll taxes, a 401(k) contribution and health premiums, paying down a credit card.
| Line | Assigned | Running balance |
|---|---|---|
| Take-home income | $5,500 | |
| Rent or mortgage | $1,500 | $4,000 |
| Utilities | $300 | $3,700 |
| Phone and internet | $150 | $3,550 |
| Groceries | $600 | $2,950 |
| Car payment, insurance, fuel | $550 | $2,400 |
| Health costs not covered by payroll | $150 | $2,250 |
| Credit card (minimum plus extra) | $500 | $1,750 |
| Emergency fund | $400 | $1,350 |
| Roth IRA | $375 | $975 |
| Sinking funds: car repairs, holidays, gifts | $250 | $725 |
| Dining out | $200 | $525 |
| Entertainment and subscriptions | $150 | $375 |
| Clothing and personal care | $150 | $225 |
| Charitable giving | $100 | $125 |
| Buffer | $125 | $0 |
Of the $5,500, $1,525 (28%) goes to savings and extra debt payments, before counting the 401(k) already taken out of pay. That is the practical difference: the saving happens because it was assigned first, not because money happened to be left over. If the credit card runs at the 22.15% average rate the Federal Reserve reported for Q2 2026, putting $500 a month toward it is one of the best returns in this budget; see how to pay off credit card debt.
Sanity-Check It Against Real Spending
If you have no idea what a category should cost, federal spending data give a starting point. What the average US household spent in 2024, per month:
| Category | Average per month | Share of spending |
|---|---|---|
| Housing (shelter, utilities, household operations, supplies, furnishings) | $2,189 | 33% |
| of which shelter | $1,360 | 21% |
| of which utilities, fuels and public services | $395 | 6% |
| Transportation | $1,110 | 17% |
| Food (groceries and eating out) | $847 | 13% |
| Personal insurance and pensions (mostly Social Security and retirement contributions) | $816 | 12% |
| Healthcare | $516 | 8% |
| Entertainment | $301 | 5% |
| Cash contributions (gifts and giving) | $191 | 3% |
| Apparel and services | $167 | 3% |
| Education | $131 | 2% |
| Everything else | $277 | 4% |
| Total | $6,545 | 100% |
Averages blend very different households, so use them to spot a category that is far out of line, not as a target. Our pages on the average grocery bill, the average electric bill and average monthly expenses go further, including by household size.
Zero-Based vs 50/30/20
| Zero-based | 50/30/20 | |
|---|---|---|
| How it works | Every dollar assigned to a named line | Three buckets: needs, wants, savings and debt |
| Effort | High: a monthly plan and tracking | Low: check the split occasionally |
| Control | Very high | Moderate |
| Best for | Debt payoff, tight budgets, people who overspend | People who already save and want a simple check |
They are not rivals. Many people use 50/30/20 as the target split and a zero-based budget to hit it. Our 50/30/20 rule guide covers the simpler method, and the budget calculator does the split for you.
Budgeting by Paycheck
A monthly plan is easier to build, but bills do not wait for the end of the month. If you are paid more than once a month, give each paycheck its own zero-based plan: list the bills due before the next payday and pay them from that check, then assign the rest.
| Paycheck | Pays for | Example |
|---|---|---|
| 1st of the month, $2,750 | Rent (due on the 1st), half the groceries, emergency fund, retirement, health costs, part of the buffer | $1,500 + $300 + $400 + $375 + $150 + $25 = $2,750 |
| 15th of the month, $2,750 | Utilities, phone, car, credit card, the other half of groceries, sinking funds, wants, the rest of the buffer | $300 + $150 + $550 + $500 + $300 + $250 + $600 wants + $100 = $2,750 |
Paid every two weeks? That is 26 paychecks a year, so two months each year bring a third check. Build your monthly budget on two paychecks and decide in advance what the third one is for, such as the emergency fund, a sinking fund or extra debt payments. Then it gets a job instead of disappearing.
Irregular Income and Surprise Expenses
Irregular income. Budget on your lowest typical month, not your average. Fund essentials first, then savings, then wants. In a good month, the extra goes to a holding line and is assigned when it arrives, ideally to building a buffer of one month's expenses so that next month's budget can run on money you already have.
Surprises. When something unplanned happens, you do not break the budget; you move money. Take it from a lower-priority line (dining out, entertainment) and write the change down. If a surprise cannot be covered that way, that is what the emergency fund is for, and the next month's plan should start rebuilding it.
Making It Stick
- Automate the savings lines on payday, so they happen before you can spend the money.
- Do a 15-minute weekly check of actual spending against each line, rather than one painful reconciliation at month-end.
- Give yourself a guilt-free spending line. Budgets with no room for fun get abandoned.
- Use a tool if it helps. The worksheet above downloads as a spreadsheet; budgeting apps built around the zero-based method also work. Our budgeting apps guide compares them.
- Expect the first three months to be wrong. Most people underestimate groceries and irregular costs at first. Adjust the numbers; keep the method.
Where the Name Comes From
Zero-based budgeting started as a way to run organizations, not households. Instead of taking last year's budget and adding a little, each unit starts from zero and has to justify every activity it wants to fund. Jimmy Carter used it as governor of Georgia and, as president, ordered it for the whole federal government: his memorandum of February 14, 1977 told agencies to prepare the fiscal year 1979 budget that way, citing "the success of the zero-base budget system adopted by the State of Georgia."
The household version keeps the core idea, that nothing is funded just because it was funded last month, and adds one rule: the plan has to add up to exactly what you earn.

FAQ
What is a zero-based budget?
A budget in which every dollar of take-home income is assigned to spending, saving or debt, so that income minus assignments equals zero.
Does zero-based budgeting mean I spend all my money?
No. Savings, investing and extra debt payments are assigned like any bill. "Zero" means every dollar has a plan.
How do I start a zero-based budget?
Write down next month's take-home pay, list essentials from your recent statements, assign savings and debt payments, add sinking funds for irregular costs, then assign the rest to wants and a buffer until you reach zero.
What if I overspend in one category?
Move money from another line to cover it and note the change. The total still has to add up to your income.
Is there a free zero-based budget template?
Yes: fill in the worksheet on this page and download it as a spreadsheet (CSV) that opens in Excel, Google Sheets or Numbers, with columns for what you planned and what you actually spent.
How do I do a zero-based budget if I am paid every two weeks?
Plan each paycheck separately: list the bills due before the next payday and assign the rest of that check. Two months a year bring a third paycheck; decide ahead of time what it pays for.
Is zero-based budgeting better than 50/30/20?
It gives more control and suits debt payoff or tight budgets. 50/30/20 is simpler and suits people who already save. Many people combine them.
How does zero-based budgeting work with irregular income?
Budget on your lowest typical month, cover essentials first, and assign extra income when it arrives, ideally building a one-month buffer.
Where did zero-based budgeting come from?
From organizational budgeting, where every program has to justify its funding from zero each year. Jimmy Carter used it in Georgia and ordered it for federal agencies in a memorandum dated February 14, 1977.
This article is for general information and is not financial advice. Spending data are from the BLS Consumer Expenditure Surveys (checked 2026-09-30) and the card rate from the Federal Reserve G.19 (re-checked 2026-10-23). The budget example is hypothetical.
