About the Cost of Doing Business Calculator
The cost of doing business is the total annual expense required to keep your business running — from fixed overhead like rent and insurance to variable costs, owner compensation, debt service, taxes, and marketing. Understanding this number is critical because it tells you exactly how much revenue you must generate just to break even, and what hourly rate you need to charge to sustain operations.
Many small business owners focus on revenue without fully accounting for all costs, leading to underpricing, cash flow problems, and ultimately failure. For service businesses and freelancers, knowing your true cost of doing business per hour is essential for setting rates that actually cover expenses and leave room for profit. A freelancer with $80,000 in annual costs and 1,600 billable hours needs to charge at least $50/hour just to break even — before any profit.
This calculator aggregates all your business costs into a single view, breaks them down by category, and computes your minimum viable revenue, hourly rate, and daily cost of operations. The revenue scenario table shows how your profitability changes at different revenue levels — essential for growth planning and pricing strategy.
When This Page Helps
Knowing your exact cost of doing business prevents the #1 small business mistake: underpricing. This calculator turns your scattered expenses into clear metrics — minimum rates, break-even revenue, and daily operating cost — so you can price with confidence and decide whether your current volume can support the business.
How to Use the Inputs
- Enter your annual revenue or projected revenue
- Fill in each cost category (fixed, variable, salary, debt, etc.)
- Enter your estimated billable hours per year for hourly rate calculation
- Review total costs and break-even requirements
- Study the cost breakdown to identify largest expense categories
- Use revenue scenario table for planning and what-if analysis
Formula used
Total Cost = Fixed + Variable + Owner Salary + Debt + Tax + Insurance + Marketing
Monthly Cost = Total ÷ 12
Daily Cost = Total ÷ 365
Hourly Cost = Total ÷ Billable Hours
Break-Even Revenue = Total Cost (where profit = 0)
Min Hourly Rate = Total Cost ÷ Billable Hours
Suggested Rate = Min Rate × 1.30 (includes 30% margin)Example Calculation
Result: Total cost $456,000 — $38,000/month — min $228/hr for 2,000 billable hrs
Costs total $456K/year. You need $38K/month just to stay afloat. At 2,000 billable hours, your cost is $228/hr. To earn a 30% margin, charge at least $296/hr. Revenue of $500K leaves $44K net profit (8.8% margin).
Tips & Best Practices
- Track every expense for a year before setting rates — most people underestimate costs by 20-30%
- Include owner salary at market rate, not just what you currently draw
- Billable hours are ALWAYS less than total hours — account for admin, marketing, and downtime
- Add a 15-30% margin above your min hourly rate — zero profit is not a business
- Review and update this calculation quarterly as costs and revenue change
Rate Setting Inputs
Include owner compensation, debt payments, and recurring software or service subscriptions when building the cost base. If you work with billable hours, use a conservative estimate so your hourly rate does not understate the real cost of labor.
Costing Mistakes
Leaving out taxes, owner pay, or non-billable time makes the result look healthier than it is. Another common mistake is treating every expense as fixed when some costs rise with sales volume or output.

Methodology
This worksheet adds the entered annual cost buckets to estimate total operating cost, then converts that total into monthly cost, daily cost, cost per billable hour, and break-even revenue. When billable hours are supplied, it also derives a minimum hourly rate from `total cost / billable hours` and a suggested rate by applying the page’s fixed 30% margin uplift.
The totals are only as complete as the inputs provided. The page is a pricing and planning worksheet, not a substitute for a full income statement or job-costing system, and it does not classify expenses for tax or accounting purposes beyond the categories entered on the form.

Frequently Asked Questions
It's the foundation of pricing strategy. If you don't know your total costs, you can't set profitable prices. Many businesses fail not from lack of revenue but from not understanding their true cost structure, leading to chronic underpricing.
Fixed costs stay the same regardless of sales volume: rent, insurance, salaries, loan payments. Variable costs change with volume: materials, shipping, sales commissions, credit card processing fees. Some costs are semi-variable (utilities, phone).
For solo professionals: 1,200-1,600 hours/year is realistic (60-80% of 40-hour weeks after admin, marketing, vacation). Employees: 1,800-2,000 hours. Always use conservative estimates — overestimating billable hours leads to underpricing.
Absolutely. If you don't pay yourself, your business isn't truly profitable — it's subsidized by your labor. Include market-rate compensation for your role. This is also called "opportunity cost" of your time.
A P&L (income statement) shows actual results. This calculator is forward-looking — it helps you plan by modeling different cost and revenue scenarios. Use actual P&L data from last year as inputs for more accurate projections.
It varies by industry: Retail 90-95%, Services 60-80%, Software/SaaS 40-60%. Generally, total costs below 80% of revenue is healthy for most businesses, leaving 20%+ for profit and reinvestment.
