// 3. Add Profit Margin
// Total Target = TotalOperationalCost * (1 + Profit%)
var totalTargetRevenue = totalOperationalCost * (1 + (profitMargin / 100));
// 4. Calculate Total Hours
var totalBillableHours = hoursPerWeek * weeksPerYear;
// 5. Calculate Hourly Rate

How to Calculate Service Rate: A Guide for Professionals
Whether you are a freelancer, a consultant, or running a service-based agency, determining the correct service rate is critical to the financial health of your business. Charging too little leads to burnout and cash flow problems, while charging too much without justification can alienate potential clients. This guide explains the methodology behind calculating a sustainable hourly or project-based service rate.
What is a Service Rate?
In a professional context, your service rate is the monetary amount you charge for a unit of your time or output. While often expressed as an hourly rate, it is fundamentally a calculation of your business's revenue requirements divided by your capacity to deliver work. A properly calculated service rate covers three things:
- Personal Income: The salary you need to pay your personal bills and save.
- Overhead Costs: The expenses required to run the business (software, hardware, rent, insurance).
- Profit & Tax: The surplus needed for business growth, taxes, and rainy-day funds.
The Formula for Calculating Service Rate
The basic math for finding your hourly service rate is straightforward, yet many professionals overlook critical variables. The formula is:
Hourly Rate = (Total Annual Costs + Desired Profit) / Total Billable Hours
Step 1: Calculate Total Financial Requirements
First, sum up everything you need to earn. This includes your Desired Annual Salary (net) and your Business Overheads. If you are a freelancer, do not forget to account for taxes. A common mistake is treating all revenue as income; typically, 20-30% of your service rate goes immediately to taxes.
Step 2: Determine True Billable Hours
This is where most calculations fail. You might work 40 hours a week, but you cannot bill for 40 hours. You must account for:
- Admin tasks: Invoicing, emails, and meetings.
- Marketing: Finding new clients and networking.
- Time off: Vacation, sick days, and holidays.
A realistic billable utilization rate for a solopreneur is often around 60-70%. If you work 40 hours a week, you might only be able to bill for 25 to 30 of them. Our calculator above allows you to input "Billable Hours" specifically to ensure accuracy.
Step 3: Factor in Profit Margin
A "break-even" rate covers your salary and costs, but a business needs profit to grow. Adding a profit margin buffer (e.g., 10-20%) ensures that you have funds to invest in new equipment or education without dipping into your personal salary. It also provides a cushion for lean months where billable hours might drop.
Example Calculation
Let's say you want to earn a net salary of $80,000. You estimate $20,000 in taxes and $10,000 in business overheads. Your total target revenue is $110,000.
You plan to work 48 weeks a year (4 weeks vacation). Although you work 40 hours a week, you only spend 25 hours on client work (billable).
Total Billable Hours = 48 weeks × 25 hours = 1,200 hours.
Service Rate = $110,000 / 1,200 hours = $91.67 per hour.
In this scenario, charging anything less than $92/hour means you are effectively underpaying yourself or failing to cover overheads.
Conclusion
Using a calculator to determine your service rate removes the guesswork from pricing. It shifts the conversation from "what does the market pay?" to "what does my business need?" Once you know your minimum viable rate, you can confidently negotiate contracts that ensure your business remains profitable and sustainable.
