How to calculate a gross margin

To calculate your gross profit margin you’ll need to have all your costs and revenue to compare.

Calculation: revenue - cost = gross profit ÷ revenue x 100 = margin.

For example, if your revenue on a given project is currently $54,000 and your costs are $46,000 your exact margin will be 14.8%.

Example calculation: 54,000 - 46,000 = 8,000 ÷ 54,000 x 100 = 14.8%.

How to automate margin calculation?

The most difficult part of calculating your margin is gathering all the relevant information. Using PSA software, you’ll be inputting all the data you need in one place through timesheets and invoices. That data is then gathered in real-time to show you your current profit margin, often expressed as a percentage—no manual calculations needed!

For a predicted profit margin of your project, you’ll also want to use PSA software, as it can be a confusing process to manually calculate what revenue you expect to bring in from any given project once you’re underway. Data from your timesheets, invoices, planned fixed-fee or T&M billing, and your future resource plan all connect to produce a predicted profit percentage.

Common mistakes to avoid

Calculating profit margins for professional service firms can be complex, and various errors can compromise your accuracy. Here are 4 common mistakes to avoid:

1. Not including all costs leads to an incomplete understanding of total product or service expenses, like project costs and overhead.
2. Neglecting elements like employee benefits and training.
3. Failing to recognize revenue on time. If you’re struggling to get invoices out and paid on time, consider using PSA software to support the process.
4. Outdated information can give a wrong idea of the business's financial health. This is because it may not show the current costs, market conditions, or revenue patterns.
