Business Budget Calculator
Free online business budget calculator to estimate planned expenses, expected budget balance, profit margin, and expense ratio from projected revenue and cost assumptions. This calculator is useful for business owners, startup founders, managers, finance teams, and students who want a simple way to organize a business budget before a month, quarter, or year begins. A good budget helps a business plan spending, estimate profit, and decide whether expected revenue can comfortably support operating costs.
The calculator works with projected revenue, fixed costs, variable costs, and other budgeted costs. Fixed costs are expenses that usually stay stable during the period, such as rent, insurance, and salaries. Variable costs rise or fall with activity, such as materials, shipping, commissions, or production-related expenses. Other budgeted costs can include marketing, software, travel, or one-time planned spending. Once the values are entered, the calculator shows total budgeted expenses, net budget balance, profit margin, and expense ratio.
The formula of business budget
Total budgeted expenses = Fixed costs + Variable costs + Other budgeted costs
Net budget balance = Projected revenue – Total budgeted expenses
Profit margin = (Net budget balance / Projected revenue) x 100
Expense ratio = (Total budgeted expenses / Projected revenue) x 100
Here projected revenue means the expected income for the selected period, fixed costs are costs that usually do not change much during the period, variable costs are costs that change with output or sales volume, and other budgeted costs include planned expenses that do not fit neatly into the first two groups. Net budget balance shows the expected surplus or shortfall after all planned expenses are deducted from revenue.
Solved Example
Example 1: Find the budget result if projected revenue is $180,000, fixed costs are $60,000, variable costs are $45,000, and other budgeted costs are $15,000.
Solve: Total budgeted expenses = 60000 + 45000 + 15000 = $120,000
Net budget balance = 180000 – 120000 = $60,000
Profit margin = (60000 / 180000) x 100 = 33.33%
Expense ratio = (120000 / 180000) x 100 = 66.67%
Example 2: Find the result if projected revenue is $95,000, fixed costs are $35,000, variable costs are $28,000, and other costs are $12,000.
Solve: Total budgeted expenses = 35000 + 28000 + 12000 = $75,000
Net budget balance = 95000 – 75000 = $20,000
Profit margin = (20000 / 95000) x 100 = 21.05%
Expense ratio = (75000 / 95000) x 100 = 78.95%
Example 3: Find the result if projected revenue is $250,000, fixed costs are $90,000, variable costs are $82,000, and other costs are $28,000.
Solve: Total budgeted expenses = 90000 + 82000 + 28000 = $200,000
Net budget balance = 250000 – 200000 = $50,000
Profit margin = (50000 / 250000) x 100 = 20%
Expense ratio = (200000 / 250000) x 100 = 80%

How to use this business budget calculator
Enter the projected revenue in the proper input field. After that, enter fixed costs, variable costs, and other budgeted costs for the same planning period. Then click the calculate button. The calculator will show the total budgeted expenses, net budget balance, profit margin, and expense ratio in the result box. Make sure all amounts belong to the same month, quarter, or year so the output is meaningful.
This calculator is useful when building a monthly budget, reviewing annual plans, testing different cost assumptions, or setting revenue targets. If the net budget balance is low or negative, the business may need to reduce costs, improve pricing, or raise sales expectations. If the profit margin is healthy and the expense ratio is controlled, the planned budget may be more sustainable. These results can help guide operational, hiring, and spending decisions.
When using the result, remember that a business budget is based on estimates and assumptions. Actual revenue and actual costs may differ because of seasonality, demand changes, supplier pricing, or one-time expenses. Even so, a simple budget model is a strong starting point for planning and accountability. This calculator gives a fast numerical view that supports budgeting, performance forecasting, and better financial discipline.
