Use this free Budget Planner to compare your monthly income with your spending. Add the money coming in, list your regular expenses, and see whether you have money left over or are spending more than you earn.
A budget is a planning tool. It helps you see where your money is going, prepare for upcoming bills, and make more informed choices about spending, saving, and financial goals.
How to use the Budget Planner
- Enter your total monthly income after tax, including regular income from work, benefits, support, or other reliable sources.
- Add your monthly expenses, such as housing, utilities, food, transport, debt payments, savings, and other spending.
- Select Calculate Budget.
- Review your total income, total expenses, and remaining monthly balance.
For the most realistic result, use average monthly amounts. If you pay an annual or quarterly bill, divide it by 12 to estimate its monthly cost.
Budget example
Suppose your monthly income is $3,500.
Your monthly expenses are:
- Rent: $1,100
- Utilities: $250
- Groceries: $450
- Transport: $250
- Debt payments: $300
- Phone and internet: $120
- Savings: $400
- Other spending: $80
Your total monthly expenses are $2,950.
$3,500 income – $2,950 expenses = $550 remaining
In this example, you have a monthly surplus of $550. You could use that amount for additional savings, debt repayment, planned purchases, or a buffer for irregular costs.
How to read your budget result
A positive result means your income is greater than your listed expenses. This is often called a budget surplus or remaining balance.
A negative result means your expenses are greater than your income. This is often called a budget shortfall.
A surplus does not automatically mean every financial goal is covered. Review whether you included irregular expenses, annual bills, savings goals, and upcoming costs.
A shortfall does not mean you have failed. It shows that your current plan needs attention. Start by checking whether income or expenses were missed, then identify which categories may be adjusted.
Expenses to include in a monthly budget
A useful budget includes both regular bills and less frequent costs.
Common monthly budget categories include:
- Rent or mortgage payment
- Property taxes, homeowners insurance, or renters insurance
- Electricity, water, gas, and internet
- Groceries and household supplies
- Transport, fuel, parking, public transit, and car maintenance
- Mobile phone and subscriptions
- Childcare, education, and health expenses
- Credit-card, loan, or other debt payments
- Savings and emergency-fund contributions
- Entertainment, clothing, gifts, and personal spending
- Pet care and other household costs
Look back over several months of bank or card statements when possible. This can help you spot infrequent costs, including insurance, medical bills, travel, gifts, seasonal spending, and repairs.
Budgeting for irregular expenses
Some expenses do not arrive every month, but they should still be part of your plan.
For example, if your car insurance costs $720 per year, divide it by 12:
$720 / 12 = $60 per month
Set aside approximately $60 each month so the annual bill is less likely to cause a surprise.
The same approach can be used for annual subscriptions, school costs, holidays, home maintenance, vehicle repairs, and planned travel.
Budget surplus and savings goals
If your budget shows money left over, decide where it needs to go before it is spent by accident.
You might use a surplus to:
- Build emergency savings
- Pay down high-interest debt
- Save for a home, education, travel, or another goal
- Cover irregular expenses
- Increase retirement or long-term savings contributions
- Create more room in your monthly cash flow
Your priorities will be personal. A budget does not need to follow a fixed rule to be useful. The best budget is one that reflects your actual income, obligations, needs, and goals.
When a monthly budget is not enough
A monthly budget shows the total money expected to come in and go out during a month. It may not show whether the timing of payments creates a problem.
For example, you may have enough income overall but still run short before payday because rent, utilities, and a loan payment are due in the same week.
If this happens, review the timing of your income and bills. Track cash flow week by week, keep a small buffer when possible, and contact a bill provider directly if you need to ask about a different due date.
Frequently asked questions
The 50/30/20 rule suggests spending 50% of after-tax income on needs, 30% on wants, and 20% on savings and
debt repayment. It’s a useful starting point, not a law as the page notes, the best budget reflects your
actual income and obligations. If housing alone eats half your income where you live, adjust the split rather
than forcing the rule to fit.
Use an average of the last 3–6 months as your income figure, and budget toward the lower end so lean months
still work. In strong months, move the extra straight to savings before lifestyle spending absorbs it. Re-run
the Budget Planner each month with your updated numbers so the plan stays honest.
First double-check that nothing was missed on either side a shortfall often comes from forgotten income or
expenses. Then cut in this order: discretionary wants first, then renegotiable bills like subscriptions and
phone plans, and only then look at raising income. Avoid cutting savings to zero if you can — even a small
emergency buffer prevents new debt.
Review it monthly. Income, subscriptions, and spending all drift, and a quick 10-minute check at the start of
each month beats one big annual overhaul. Re-run the calculator whenever something changes: a raise, a move,
a new bill, or a new savings goal.
