Capital Structure: Explained

What is it, how to calculate it, formula, why it's important

Hey folks, it's good to be back! Today, we're going to be talking about a topic that's pretty crucial to every single company out there- capital structure. Yeah, I know it sounds a bit boring and maybe even intimidating, but trust me, it's not that bad! Stick around with me for a bit, and we'll get through this together.

Okay, let's start with the basics. Capital structure refers to how a company finances its operations and growth through different sources of funding or capital. These can include equity (money raised from shareholders), debt (borrowed money from banks or other lenders), and any other form of long-term financing.

Now, why should you care about this? Well, for one thing, capital structure can have a big impact on a company's overall financial health and stability. If a company relies too heavily on debt, for example, it might struggle to make payments and fall into financial trouble. On the other hand, if a company has a lot of equity, it might be less risky but also less able to take on big opportunities or investments.

To better understand capital structure, let's break it down into a few key components:

Debt-to-Equity Ratio

The debt-to-equity ratio is a measure of how much debt a company has relative to its equity. Basically, it's the amount of money the company owes compared to the amount of money shareholders have invested in the company. The formula for this ratio is simple:

Debt-to-equity ratio = Total debt / Total equity

A high debt-to-equity ratio means a company has a lot of debt compared to equity, while a low ratio means the opposite. A healthy balance of debt and equity depends on the industry and company, but as a general rule, a low to moderate debt-to-equity ratio is better than a high one.

Cost of Capital

Cost of capital refers to the overall cost a company pays for its capital, taking into account both equity and debt. This includes interest payments on loans, dividends paid to shareholders, and any other costs associated with raising capital. The cost of capital is important because it helps companies determine the minimum return they need to make on investments in order to meet their financial obligations.


The weighted average cost of capital, or WACC, is a more complex calculation that takes into account the different sources of funding a company uses and the relative weights of each. It's basically an average of the cost of each type of capital, weighted by how much of each is used. The formula for WACC is:

WACC = (E / V x Re) + (D / V x Rd x (1 - Tc))


E = market value of the company's equity

D = market value of the company's debt

V = total value of the company (E + D)

Re = cost of equity

Rd = cost of debt

Tc = corporate tax rate

Don't worry too much about the formula- the important thing to understand is that WACC is used to determine the minimum return that a company needs on its investments.

Equity Financing vs. Debt Financing

As I mentioned earlier, there are two main types of funding that companies use: equity financing and debt financing. Equity financing involves selling shares of the company to investors in exchange for capital. This can come in the form of initial public offerings (IPOs), private placements, or other methods. The benefits of equity financing are that it doesn't need to be paid back like debt, and there are no interest payments. However, equity financing also means giving up some control of the company and potentially sharing profits with shareholders.

Debt financing, on the other hand, involves borrowing money from lenders and paying it back over time with interest. This can come from banks, bonds, or other lenders. The benefits of debt financing are that it can be less risky and doesn't dilute ownership like equity financing. However, debt also means making regular interest payments and meeting other obligations like principal payments.

Closing Thoughts

So, there you have it- a crash course in capital structure! I hope this helps demystify some of the jargon and complexities around financing and funding. Remember, the way a company structures its capital can have long-lasting effects on its financial health and future growth. So, whether you're an investor, entrepreneur, or just curious, it's important to understand how capital structure works. Thanks for joining me, and see you next time!
