Today I want to share a quick 3-Step Guide for calculating hourly charge-out rates for Architects and Design Professionals.
Let’s start by reviewing the annual salary requirements for the average Architect.
Hourly Rates and Median Salary Requirements
According to America’s Bureau of Labor and Statistics, Architects earn a median salary of $79,380 per year (May 2018).
So what would be the hourly rate for self-employed Architects (or Interior Designer) who wants to maintain an annual salary of $79,380 per year?
The wrong way to calculate hourly rates:
There is a common misconception in our industry, that to calculate an hourly charge-out rate all you need to do is take your annual salary and divide it by the total number of working hours.
For example, if you’re earning $79,380 per year and you’re working a 40-hour week, then you may believe that your hourly charge out rate will be:
Unfortunately, this calculation fails to take into consideration two very important factors; the cost of doing business and the number of billable hours (not workable hours).
So, let’s calculate the cost of doing business and the number of billable hours:
The right way to calculate hourly rates:
Step 1: Calculate the cost of doing business:
Start by adding up all your business expense costs including rent, furniture, utilities, services, equipment, supplies, accounting fees, legal fees. I.T. fees, software fees, industry membership fees, insurance costs, professional membership fees, certifications, advertising/marketing costs, and taxes (Don’t forget that company and payroll taxes could be significant depending on your legal structure and location).
For the sake of this example, let’s say your business expenses equate to a very modest $20,000 so your total cost of doing business will be:
Should you need any assistance estimating these costs try consulting with either your tax accountant or a a self-employed, industry peer who is willing to share their business costs with you.
Make sure you discuss your tax requirements with a qualified tax professional. Tax costs can be significant so it’s important that you understand how significant as early as possible. Also don’t forget to add a percentage to cover profit. This could be any amount but for this example, I’ve chosen 15%.
Step 2: Calculate your billable hours:
The next step is to calculate your billable hours. Billable hours are the hours worked after you have deducted for non-billable activities such as; vacation days, sick days, public holidays and inefficiencies in the workday.
So, the total hours you can invoice will be 2,080 hours less the 240 hours you’re not working.
This equates to 1,840 billable hours. Unfortunately, however, you still need to consider the time required for; coffee breaks, lunch breaks, bathroom breaks, answering phone calls, respond to emails and attending meetings.
So, we also need to consider an efficiency factor. Let say you’re only efficient for 60% of the time you’re working:
Step 3: Calculate your hourly rate:
Now that you know that the total cost of doing business is $114,287 and the total number of billable hours per year is 1,104, you can calculate your minimum hourly charge out rate:
Therefore, the minimum hourly rate that a self-employed Architect would have to charge to achieve an annual income of $79,380 would be $104 per hour.
Please note that this is a minimum, you’ll want to consultant with a your tax accountant about your tax requirements as they can be significant and will effect your hourly rate.
Other Issues Architects & Interior Designers Should Consider when Setting their Hourly Charge Out Rate:
When calculating your hourly charge out rate it’s important to be aware of what is happening in your industry both locally and globally. So be sure to compare your estimate against the fees charged by competing professionals. This can be achieved by:
• Asking peers in your industry
• Checking online salary surveys
• Researching average salary information publications
• Checking freelancing platforms
This has been a quick look at how to calculate your hourly charge out rate.
