Stop Measuring Profit the Wrong Way

What Operating Profit Actually Measures

Operating profit tells you how much money your firm is generating after covering the cost of running the business.

It’s not just revenue.

It’s not just billings.

It’s what’s left over after everything required to operate your firm has been accounted for.

The real value of this KPI is comparison:

• Comparing one year to another
• Comparing project types
• Comparing client segments
• Comparing individual projects
  

But those comparisons only work if you’re using the right inputs.

The Problem: Most Firms Use the Wrong Revenue Number

There are two very different revenue numbers in your firm:

1. Total Revenue

This is the money coming in the door.

It includes:

• Design fees
• Reimbursable expenses
• Consultant billings
  

It looks strong—but a large portion of it is not yours to keep.

In some firms, 30% to 50% (or more) of total revenue is passed straight through to consultants and expenses.

2. Net Revenue (The Number That Matters)

Net revenue is what your firm actually retains to operate.

Formula:

Net Revenue = Total Revenue – Consultants – Direct Expenses

This is the money available to:

• Pay your staff
• Cover overhead
• Generate profit
  

If you ignore this distinction, your profitability metrics will be distorted.

Why This Matters: A Real Example

Let’s look at two firms:

Firm A (Architecture)

• Total Revenue: $1,000,000
• Net Revenue: $595,000
• Operating Profit: $152,000
  

Firm B (Engineering)

• Total Revenue: $608,000
• Net Revenue: $595,000
• Operating Profit: $152,000
  

At first glance, Firm A looks larger and potentially stronger.

If you calculate operating profit using total revenue:

• Firm A: 15.2%
• Firm B: 25%
  

That suggests Firm B is significantly outperforming.

But that’s misleading.

The Fix: Normalize Using Net Revenue

Now calculate operating profit correctly:

Operating Profit % = Operating Profit ÷ Net Revenue

• Firm A: $152,000 ÷ $595,000 = 25.5%
• Firm B: $152,000 ÷ $595,000 = 25.5%
  

They are performing identically.

The difference in total revenue was driven by consultant fees—not operational performance.

This is why using total revenue creates false conclusions.

The Correct Formula

Use this. Every time.

Operating Profit % = Operating Profit ÷ Net Revenue

That’s it.

This gives you a clean, normalized metric you can use across:

• Projects with consultants vs. without
• Different project types
• Different client segments
• Different time periods
  

Now you’re comparing apples to apples.

What Good Looks Like

Across A/E firms:

• Top-performing firms: 20%+ operating profit
• Average firms: Low teens
• Underperforming firms: Single digits
  

If you’re below 10%, you’re operating with very little margin for error.

If you’re in the teens, you’re likely leaving money on the table.

If you’re above 20%, you’re running a disciplined, well-managed firm.

Where This KPI Becomes Powerful

Once you’re measuring it correctly, operating profit becomes a decision tool:

1. Identify Your Best Work

Which project types produce the highest operating profit?

2. Evaluate Client Fit

Which clients consistently drive strong margins—and which ones drag you down?

3. Expose Hidden Issues

High revenue projects with low operating profit are often:

• Over-serviced
• Poorly scoped
• Staffed inefficiently
  

4. Guide Strategic Focus

You can start shifting toward:

• Higher-margin project types
• Better client segments
• More disciplined execution

The Bottom Line

Operating profit is not just a number—it’s a lens. But it only works if you measure it correctly.

If you base it on total revenue, you’re mixing in money that was never yours to keep.

If you base it on net revenue, you get a clear, comparable, decision-ready metric.

And once you have that, you can stop guessing—and start managing your firm based on what actually drives profit.
