A monthly budget planner is a worksheet that assigns each part of next month's take-home income to a category, such as housing, food, transport, savings and debt, before the month begins. This planner starts from a preset split like 50/30/20, lets you edit every category by percent or amount, and shows what is still unassigned.
How to Use the Monthly Budget Planner
- Enter your monthly take-home income (after tax) and pick a currency.
- Choose a starting split: 50/30/20, 70/20/10, 60/20/10/10, or Custom with eight everyday categories.
- Edit the categories. Rename them, change the numbers, add lines with "+ Add category" or remove them with the × button. Switch between "Percent of income" and "Absolute amount" at any time.
- Read the summary. Income, Allocated and Remaining update as you type, and the status line tells you whether the plan is fully allocated, has a surplus, or is over-allocated.
- Save, print or export. Name the plan with the month and press Save plan. Next month, press Copy last month, adjust what changed and save again.
Clear all empties the planner and returns it to 50/30/20; your saved plans stay in the list until you delete them.
Worked Example: $5,000 a Month in Each Preset
These are the amounts the planner shows when you enter 5000 as income and select each preset.
| Preset | Category amounts | Allocated | Remaining |
|---|---|---|---|
| 50 / 30 / 20 | Needs $2,500 · Wants $1,500 · Savings and debt repayment $1,000 | $5,000 (100.0%) | $0 |
| 70 / 20 / 10 | Living expenses $3,500 · Savings $1,000 · Debt / giving $500 | $5,000 (100.0%) | $0 |
| 60 / 20 / 10 / 10 | Essentials $3,000 · Savings $1,000 · Emergency fund $500 · Discretionary $500 | $5,000 (100.0%) | $0 |
Change Wants in the 50/30/20 plan from 30% to 25% and the summary reads Allocated $4,750 (95.0%), Remaining $250, with the status "Surplus of $250 unassigned". Raise Needs to 60% instead and it reads Allocated $5,500 (110.0%), Remaining -$500, "Over-allocated by $500".
How the 50/30/20 Rule Works
The 50/30/20 rule splits take-home pay into three buckets: 50% for needs (rent or mortgage, groceries, utilities, transport, insurance, minimum debt payments), 30% for wants (dining out, entertainment, subscriptions, hobbies), and 20% for savings and extra debt payoff. It was popularized by Elizabeth Warren and Amelia Warren Tyagi in their book All Your Worth: The Ultimate Lifetime Money Plan (Free Press, first published 2005), which calls the 50% bucket "must-haves" (summary of the rule).
The 70/20/10 and 60/20/10/10 presets are common variations with no single published source. Treat all three as starting points to edit, not as targets you must hit.
Custom Categories and Fixed Amounts
Not every household fits a preset. If rent alone is 45% of your income, a 50% needs bucket is already strained. Custom starts you with Housing, Food, Transport, Utilities, Savings, Entertainment, Debt and Other, and you can add lines such as Childcare, Giving or an emergency fund. In "Absolute amount" mode each category holds a fixed sum, so a $400 savings goal stays $400 when your income changes and only its percentage moves.
How Much of a Budget Goes to Housing? The 30% Benchmark
The best-known housing benchmark comes from the US Department of Housing and Urban Development. HUD counts a household as cost-burdened when monthly housing costs, including utilities, exceed 30% of monthly income, and as severely cost-burdened above 50% (HUD CHAS definitions; US Census Bureau, September 2024). It is a statistical yardstick, not a rule you must follow. This planner works with take-home income, so the same rent is a larger share here than it would be against pre-tax pay.
What US Households Spend Each Month (BLS, 2024)
For comparison, the Bureau of Labor Statistics Consumer Expenditure Survey reports average annual spending of $78,535 per consumer unit in 2024, with average income before taxes of $104,207 (Consumer Expenditures 2024, released December 19, 2025). The monthly column is the annual figure divided by 12.
| Category | Per year (2024) | Per month | Share of spending |
|---|---|---|---|
| All spending | $78,535 | $6,545 | 100% |
| Housing | $26,266 | $2,189 | 33.4% |
| Transportation | $13,318 | $1,110 | 17.0% |
| Food (at home $6,224, away $3,945) | $10,169 | $847 | 12.9% |
| Personal insurance and pensions | $9,797 | $816 | 12.5% |
| Healthcare | $6,197 | $516 | 7.9% |
These are averages across all US households, including owners without a mortgage and high earners. They describe what people spend, not what you should spend.
Planning Versus Tracking
Tracking tells you where your money went; planning decides where it will go. Use this planner before the month starts, then record real spending with the Personal Budget Tracker and compare the two when you plan the next month. If you prefer paper, the Consumer Financial Protection Bureau publishes free worksheets, including a spending tracker and a cash flow budget, in its Your Money, Your Goals toolkit.

Frequently Asked Questions
What is the 50/30/20 budgeting rule?
The 50/30/20 rule allocates 50% of take-home income to needs (housing, food, utilities, transport), 30% to wants (entertainment, dining out), and 20% to savings and debt repayment. It was popularized by Elizabeth Warren and Amelia Warren Tyagi in their book All Your Worth, first published in 2005, and is a simple starting framework rather than a fixed target.
How is this different from a budget tracker?
This is a planner, not a tracker. You plan how you will allocate next month’s income before spending happens. A tracker logs what you actually spent after the fact. Plan first with this tool, then track the month with the Personal Budget Tracker.
Can I save plans and reuse them each month?
Yes. Name each plan (for example October 2026 Plan) and save it. Past plans are listed below the planner. Click Load to edit, or use Copy last month to start a new plan from your most recent one. All plans stay in your browser.
Does this work for any currency?
It works with ten currencies: USD, EUR, GBP, INR, BDT, CAD, AUD, JPY, CNY and NGN. The currency symbol updates everywhere. You can also enter fixed amounts instead of percentages.
Is my data private?
Yes. Every plan is stored in your browser’s localStorage. Nothing is uploaded to any server. Clear browser data and plans are removed — export as CSV first if you want a backup.
How does the monthly streak work?
Each time you save a plan in a new calendar month, your streak increases by one. Skip a month and it resets. The counter is a simple way to build the habit of planning before each month starts.
What makes a good monthly budget planner for irregular income?
For freelancers, commission earners, or gig workers, a cautious approach is to set income to your lowest typical month, not the average. Plan needs and minimum debt payments against that floor so the worst month still works, and put any surplus from better months into a buffer category. In Custom you can add a line called Buffer or Slow Month Reserve.
How is a monthly budget planner different from envelope budgeting?
Envelope budgeting (cash or digital) physically separates money so you cannot overspend a category. A monthly budget planner sets the plan; envelopes enforce it. Use the planner to decide percentages and amounts at the start of the month, then move those amounts into separate bank accounts or app envelopes for real enforcement. The two work together — neither replaces the other.
What does the average US household spend per month?
The BLS Consumer Expenditure Survey reports average spending of $78,535 per household (consumer unit) in 2024, about $6,545 a month. Housing was $26,266 (33.4%), transportation $13,318 (17.0%), food $10,169 (12.9%), personal insurance and pensions $9,797 (12.5%) and healthcare $6,197 (7.9%). These are averages across all households, released in December 2025, not targets for your own plan.
How much of my monthly budget should go to housing?
There is no single rule, but the usual benchmark is 30%. HUD counts a household as cost-burdened when monthly housing costs, including utilities, exceed 30% of monthly income, and severely cost-burdened above 50%. This planner uses take-home income, so the same rent shows as a higher share here than it would against pre-tax pay.
How do I make a monthly budget plan?
Start with your monthly take-home income. Give every part of it a category: housing, food, transport, utilities, debt payments, savings and personal spending. Adjust the numbers until the allocated total equals your income, so nothing is left unassigned and nothing is over-allocated. Save the plan, then review it against real spending at the end of the month.
What happens if my categories add up to more than my income?
The planner shows the plan as over-allocated and tells you by how much, for example Over-allocated by $500 when $5,500 is assigned against $5,000 of income. Lower one or more categories, or raise the income figure if it was too low, until Remaining reaches zero.
