Finance Fundamentals: Return on Capital

The Ultimate Efficiency Metric for Business Leaders

When you strip back the noise of business performance, there are a handful of financial metrics that genuinely tell you if your company is working as hard as you are. One of the most powerful, and one that too many business leaders overlook, is Return on Capital (ROC).

This isn’t just an accountant’s formula. It’s the real-world measure of how well you’re using the assets and resources in your business to generate profit. Get it right, and it becomes your compass for growth, efficiency, and financial control. Get it wrong, and you’re left wondering why all that effort isn’t turning into meaningful returns.

Today, let’s break down what ROC is, why it matters, what a good benchmark looks like, and how you can improve it. And, importantly, we’ll talk about how CFO Dynamics helps businesses like yours turn this into a competitive edge.

What is Return on Capital?

The formula is deceptively simple:

ROC = EBIT ÷ (Working Capital + Fixed Assets)

That’s Earnings Before Interest and Tax divided by your Working Capital and Fixed Assets combined.

Now, each of those terms has its own role:

• EBIT (Earnings Before Interest and Tax): Your profitability before the impact of financing and tax decisions.

• Working Capital: The cash locked up in the day-to-day running of your business. It’s debtors (customers who owe you) + stock (what’s sitting in your warehouse) + work in progress (jobs half-finished) – creditors (suppliers you owe).

• Fixed Assets: Your tangible assets—factories, machinery, vehicles, equipment—anything you use to run the business.

Why include working capital and fixed assets? Because they are tangible resources. Stock can be turned into cash. Debtors become payments in your bank account. Work in progress, once finished, becomes revenue. And your fixed assets, while harder to liquidate, are still capital you’ve deployed in order to generate profit.

ROC, therefore, tells us: for every dollar you’ve invested into tangible resources, how much profit are you generating?

Why ROC Matters

Think of ROC as the ultimate efficiency test. It doesn’t just ask “are you profitable?” but “are you profitable relative to the capital you’ve got tied up in the business?”

It forces you to look beyond your P&L. You might be making a tidy profit, but if your stock levels are bloated, your debtors are dragging their heels, or your machines are sitting idle, that return looks less impressive.

And here’s the kicker: ROC is owner-agnostic. Whether you’re bootstrapped or bankrolled by billionaires, the formula doesn’t change. Whoever owns your business still has to contend with debtors, stock, work in progress, creditors, and fixed assets.

That’s why this metric is a consistent benchmark. It doesn’t care how deep your investor’s pockets are. It only cares about how efficiently your business converts capital into profit.

What’s a Good Return on Capital?

Here’s a rough guide:

• 30% or more: You’re doing a fantastic job. That level of efficiency is hard to sustain as your asset base grows, so celebrate it.

• 20% or less: Warning bells. This suggests inefficiencies or underperformance in profitability, working capital management, or asset utilisation.

• Between 20% and 30%: Acceptable, but room for improvement—especially if your sector naturally requires a lot of capital tied up in stock, debtors, or equipment.

It’s important to note that ROC isn’t equally useful for every business model. Service businesses, for example, often have very few tangible assets, so the calculation might not yield much insight. But if you’re in manufacturing, wholesale and distribution, or construction, ROC is pure gold. These industries naturally carry debtors, stock, work in progress, creditors, and significant fixed assets. In other words: ROC highlights whether your operations are running lean or bloated.

How to Improve Return on Capital

There are only two levers here:

• Increase EBIT (profitability)

• Decrease capital employed (working capital + fixed assets)

The art is in how you pull them.

1. Boost EBIT

Profit is the numerator in the equation, and it’s the biggest driver of improvement. Strategies here include:

• Pricing discipline (stop discounting your value away).

• Productivity improvements in labour and processes.

• Better cost control across overheads.

• Smart product mix—focusing on high-margin products or services.

The more profit you generate relative to the resources tied up in the business, the higher your ROC.

2. Optimise Working Capital

Working capital often hides inefficiency in plain sight.

• Debtors: Collect faster. Tighten credit terms, follow up proactively, and incentivise early payment.

• Stock: Avoid over-purchasing. Balance supply security with turnover speed.

• Work in Progress: Push jobs through faster to convert them into cash sooner.

• Creditors: Negotiate sensible terms without damaging supplier relationships.

Each of these steps reduces the capital you’ve got tied up unnecessarily.

3. Manage Fixed Assets

Fixed assets are necessary—but they can become a drag on ROC.

• Do you need that much equipment?

• Are you sweating your assets to their full potential?

• Can you lease instead of buy in certain cases?

Keeping your asset base as lean as possible boosts your efficiency.

Why This Metric Won’t Be Beaten by Capital Structure

ROC is not fooled by leverage. Some metrics look great if you’re heavily debt-funded, others if you’re equity-rich. ROC doesn’t play that game.

Whether your business is loaded with debt or entirely equity-financed, the equation forces you to face the same reality: how effectively are you turning tangible resources into earnings? That’s why investors, analysts, and savvy CFOs treat ROC as one of the most reliable long-term efficiency measures.

The CFO Dynamics Advantage

At CFO Dynamics, we work with business leaders in manufacturing, wholesale, distribution, and construction to not just understand these numbers but to make them work.

Return on Capital is not a “reporting” metric—it’s a management tool. Used properly, it tells you where to put your energy: profitability, stock management, debtor control, asset utilisation.

Most business owners know their EBIT. Some understand their working capital. Very few connect the dots and track ROC consistently. That’s where we come in.

We help you:

• Calculate ROC accurately and consistently.

• Benchmark your performance against realistic targets.

• Identify the levers that will move your ROC higher.

• Coach your team to understand and manage working capital.

• Support decisions on capital investment vs. efficiency.

If you’re serious about running a business that generates real returns—not just revenue—then ROC needs to be on your radar. And CFO Dynamics is here to make sure you don’t just watch the number, but improve it.

Final Word

Your Return on Capital tells you whether your business is truly efficient at turning resources into profit. It’s the bridge between your operations and your outcomes.

If you’re above 30%, you’re leading the pack. If you’re hovering below 20%, it’s time to take action. And regardless of where you sit, optimising EBIT, working capital, and fixed assets is always the right move.

The businesses that win are the ones that understand these fundamentals and apply them relentlessly.

At CFO Dynamics, we help you do exactly that.
