Billable Hourly Rate Calculator
Understanding Your Billable Hourly Rate
Calculating your billable hourly rate is a crucial step for freelancers, consultants, and any professional who charges clients based on time. It's not just about picking a number; it's about ensuring you're earning enough to cover your costs, achieve your income goals, and build a sustainable business.
This calculator helps you determine a fair and profitable hourly rate by considering several key factors:
- Desired Annual Salary: This is the amount of money you want to earn for yourself after all business expenses are paid.
- Annual Benefits & Overhead Costs: This includes all the expenses associated with running your business that aren't directly tied to a client project. Think about health insurance, professional development, software subscriptions, office rent, marketing, accounting fees, and any other operational costs.
- Target Billable Hours Per Week: This is the realistic number of hours you can expect to bill clients each week. It's important to be honest here, as it should account for non-billable tasks like administration, marketing, client communication, and professional development.
- Working Weeks Per Year: This is the number of weeks you will be actively working and available to bill clients. Consider your vacation time, holidays, and potential sick days.
The formula used is:
Total Annual Costs = Desired Annual Salary + Annual Benefits & Overhead Costs
Total Annual Billable Hours = Target Billable Hours Per Week * Working Weeks Per Year
Billable Hourly Rate = Total Annual Costs / Total Annual Billable Hours
By inputting these figures, you'll get a clear, data-driven hourly rate that supports your financial goals and business viability. Remember, this is a baseline. You might adjust it based on market rates, your experience level, and the perceived value you bring to clients.

Your Calculated Billable Hourly Rate:
$${billableHourlyRate.toFixed(2)} per hour
This rate ensures you cover your desired salary ($${desiredSalary.toLocaleString()}),
your annual overhead ($${benefitsCosts.toLocaleString()}), and are working towards
billing approximately ${billableHoursPerWeek} hours per week for ${weeksPerYear} weeks a year,
totaling ${totalAnnualBillableHours} billable hours annually.
