How to Calculate per Hour Rate

Per Hour Rate Calculator

Determining your hourly rate is crucial for freelancers, consultants, and service-based businesses to ensure profitability and cover all expenses and desired income. This calculator helps you determine a suitable hourly rate based on your income goals, expenses, and billable hours.

Understanding the Calculation

To calculate your hourly rate, you need to consider:

  • Desired Annual Income: How much you want to earn before taxes per year.
  • Annual Business Expenses: The total cost of running your business or freelance practice for a year (software, insurance, marketing, office supplies, etc.).
  • Billable Hours Per Week: The average number of hours you actually spend working on client projects or billable tasks each week. This is often less than 40 hours due to administrative tasks, marketing, and client acquisition.
  • Weeks Worked Per Year: The number of weeks you plan to work, taking into account vacations, holidays, and potential sick days.

The formula is:

Total Annual Costs = Desired Annual Income + Annual Business Expenses

Total Annual Billable Hours = Billable Hours Per Week × Weeks Worked Per Year

Hourly Rate = Total Annual Costs / Total Annual Billable Hours

Example Calculation

Let's say you want to earn $60,000 a year, have $10,000 in annual business expenses, plan to bill 30 hours a week, and work 48 weeks a year:

  • Total Annual Costs = $60,000 + $10,000 = $70,000
  • Total Annual Billable Hours = 30 hours/week × 48 weeks/year = 1440 hours
  • Hourly Rate = $70,000 / 1440 hours ≈ $48.61 per hour

In this scenario, you would need to charge approximately $48.61 per hour to meet your income goals and cover expenses.
