ROIC > WACC: Measuring 'My Value' as a Businessman Using a Financial Formula

Why do I feel like I'm wearing down despite being so busy?

I'm working frantically. I feel like I'm producing results, too. Yet, for some reason, the sense of accomplishment is thin. Have you ever felt that despite being busy, you don't have a real sense of building anything up?

One day, I applied the financial framework of 'ROIC > WACC,' used in M&A and corporate valuation, directly to myself, and the true nature of this discomfort suddenly clicked. I'd like to write about that today.

What exactly are ROIC and WACC?

It sounds difficult, but what it's saying is simple.

WACC (Weighted Average Cost of Capital) is the average 'procurement cost' of the money a company has raised to run its business. A company raises money from both shareholders (equity) and banks/creditors (debt), and WACC is the weighted average of the costs of both, based on their proportions. Roughly speaking, it represents the height of the hurdle: 'To run this business, you must produce at least this much return, or it's not worth it.'

ROIC (Return on Invested Capital) is how much return was actually generated from that invested money.

And in the world of corporate value, the relationship between the size of these two is critically important.

If ROIC > WACC, the company is creating value. If ROIC < WACC, the more it operates, the more value it destroys.

Only when you produce a return higher than the procurement cost can you say a business is 'worth it.' Conversely, if it falls below the cost, no matter how large the sales are, the more you operate, the more value is worn away. The reason the Tokyo Stock Exchange has recently been asking listed companies to 'manage with an awareness of capital cost and stock price' is precisely this point—asking whether they are producing returns that exceed their costs.

Replacing this with 'Self Inc.'

This is the main point. I want you to think of yourself as a single business entity—'Self Inc.'

You also have 'invested capital.' And there are two types.

One is Equity. The time, physical strength, passion, and seriousness toward your career that you invest yourself. The shareholder is you, and there is no obligation to repay. However, when you fail to meet expectations, the shareholder—you—is the one who suffers the most. The bigger a person's dreams and ideals, the higher this cost of equity—the required level of 'I expect this much return from my life'—becomes.

The other is Debt. The trust, expectations, deadlines, and commitments entrusted to you by your boss, company, family, and team. This has the nature of 'something that must be repaid.' However, just as debt has tax benefits, the expectations and help of others can efficiently leverage your own power if used well. People who can properly rely on others can utilize this debt cheaply and skillfully.

The average of these two, the 'cost to keep yourself running,' is your WACC. It is, so to speak, the hurdle rate of your life for running while carrying both the expectations of those around you and your own ideals.

And there is only one question to ask

Does the value you generate daily (ROIC) exceed the cost that drives you (WACC)?

This is everything.

People in a state of ROIC > WACC are building up value the more they move. They are properly returning both the expectations of those around them and the ideals they have imposed on themselves with output that exceeds them. That is why, even if they are busy, they feel a sense of accomplishment. They have a sense that they are growing.

On the other hand, if ROIC < WACC, you are working hard but failing to recover your cost of capital. The value you are creating is not keeping up with the weight of what you are carrying. This is the true nature of the 'busy but wearing yourself out' feeling mentioned at the beginning. A state close to burnout usually occurs when this inequality is reversed.

The important point here is that the question being asked is not 'how much did you earn' or 'how great are your results.'Is it worth it relative to the capital being invested? It is not about the absolute amount, but a comparison with the cost. I believe this is the core of the WACC concept and the most effective perspective for measuring one's own value.

Two ways to reverse the inequality

So, what should you do when ROIC < WACC? There are two methods, exactly the same as how finance lowers WACC.

One is to use debt wisely. Rely on others, leverage trust, and do not try to shoulder everything by yourself. The cost of debt is actually 'cheaper' than the cost of equity. Borrowing the strength of others is, financially speaking, a smart capital policy. The more you try to shoulder everything with your own equity, the higher your WACC becomes.

The other is to lower your beta. Beta is the sensitivity to market fluctuations—how much you are swayed by the environment and the winds around you. People whose expected returns fluctuate wildly due to the evaluations of others or short-term economic conditions have a high beta, which results in a high WACC. Having an unwavering core is not just a matter of mental attitude; it is a rational management decision to lower your own cost of capital.

And of course, there is the standard path of increasing the ROIC side—the value you create itself. But what I like most about this framework is that it teaches us that 'try harder' is not the only answer. Simply organizing what you carry and reducing your volatility can flip the inequality.

Conclusion

ROIC > WACC. While it may look like a dry financial formula, it is a surprisingly human yardstick for measuring 'how much you are carrying and whether you are giving back enough to justify it.'

Is your ROIC exceeding your WACC today? If you don't feel like it is, is it because you aren't producing enough, or because your costs are too high due to carrying too much—or being too volatile? It might be worth closing the books on 'You, Inc.' for once.
