How to Calculate Your Accountant Charge Out Rate
Determining the right hourly rate is critical for the sustainability of any accounting practice. Whether you are a sole practitioner or managing a firm, your rate must cover three main components: your desired salary, your business overheads, and a healthy profit margin for growth.
The Fundamental Formula
The standard logic used by professional service firms to calculate rates is as follows:
Rate = (Total Costs + Target Profit) / Billable Hours
Breaking Down the Components
- Direct Costs (Salary): This is what you want to earn as a personal income before taxes.
- Overheads: These include fixed and variable costs such as professional indemnity insurance, accounting software (Xero, QuickBooks), office rent, marketing, and professional memberships (CPA, CA).
- Billable Hours: This is the most misunderstood metric. You cannot bill 40 hours a week, 52 weeks a year. You must subtract holidays, sick leave, public holidays, and "non-billable" time spent on administration, marketing, and training.
- Utilization Rate: This represents the percentage of your working time that is actually spent on client-chargeable work. A typical target for a productive accountant is between 70% and 85%.
Real-World Example
Imagine an accountant wanting to earn a $100,000 salary with $20,000 in overheads and a 20% profit margin.
If they take 4 weeks of leave and have 10 sick/public holiday days, they have roughly 230 working days. At 7.5 hours a day, that's 1,725 potential hours. If their utilization rate is 80%, they have 1,380 billable hours.
To achieve a 20% margin on a $120,000 cost base, they need $150,000 in revenue. $150,000 divided by 1,380 hours results in a charge out rate of approximately $108.70 per hour.
