Understanding Your Cost of Doing Business
The Cost of Doing Business (CODB) is the total financial baseline required to keep your business operating while paying yourself a sustainable personal salary and achieving your business profit goals. For freelancers, consultants, agency owners, and service providers, knowing your CODB is crucial for establishing profitable pricing and billing rates.
Key Components of CODB
Calculating your minimum hourly or daily rate requires factoring in three primary elements:
- Fixed Business Overhead: Essential business operating expenses such as office rent, software subscriptions, professional insurance, marketing, accounting fees, and equipment depreciation.
- Desired Owner Compensation: Your annual personal salary or draw required to cover personal living expenses, healthcare, taxes, and retirement contributions.
- Target Net Profit: Additional business profit retained for growth, cash reserves, and reinvestment beyond your personal owner pay.
How to Calculate Your Required Billable Rate
Your total billable capacity is calculated by multiplying your working weeks per year by working days per week and hours per day, then adjusting for your billable efficiency ratio. Most service professionals spend 25% to 35% of their working time on administrative tasks, client acquisition, and operations, leaving 65% to 75% for billable client work.
Minimum Billable Hourly Rate Formula:
$$\text{Hourly Rate} = \frac{\text{Fixed Overhead} + \text{Desired Salary} + \text{Target Profit}}{\text{Total Available Work Hours} \times \text{Billable Efficiency \%}}$$

Frequently Asked Questions
What is a typical billable efficiency percentage for freelancers?
Most freelancers and independent professionals operate at 60% to 75% billable efficiency. The remaining 25% to 40% is spent on marketing, proposal drafting, invoicing, administrative tasks, and professional development.
What is the difference between break-even rate and minimum target rate?
The break-even rate covers only your overhead expenses and baseline personal salary with zero net business profit. The minimum target rate includes your business net profit margin to build cash reserves and fund business expansion.
Should taxes be included in the cost of doing business?
Yes. Self-employment taxes, income taxes, and corporate taxes should be included when estimating your required personal salary and business overhead to ensure your net take-home income meets your requirements.
