What happens to WACC when debt increases?
The WACC will initially fall, because the benefits of having a greater amount of cheaper debt outweigh the increase in cost of equity due to increasing financial risk. The WACC will continue to fall until it reaches its minimum value, ie the optimal capital structure represented by the point X.
Initial Stage → As the proportion of debt in the capital structure increases, WACC gradually decreases due to the tax-deductibility of interest expense (i.e., the “tax shield” benefits).
As the firm begins to add debt to its capital structure, the value of the firm increases due to the interest tax shield. The more debt the company takes on, the greater the tax benefit it receives, up until the point at which the company's interest expense exceeds its earnings before interest and taxes (EBIT).
In case of the Classical model, as leverage increases, WACC decreases.
Inflation can affect various elements of the WACC, most notably the outputs of valuation models and discount rates. Inflation will affect the estimate of the cost of debt (Rd) and the cost of equity (Re), which are used to calculate the WACC.
A company's WACC is likely to be higher if its stock is relatively volatile or if its debt is seen as risky, because investors will want greater returns to compensate them.
Other external factors that can affect WACC include corporate tax rates, economic conditions, and market conditions. Taxes have the most obvious consequence because interest paid on debt is tax deductible. Higher corporate taxes lower WACC, while lower taxes increase WACC.
Tax cuts, stimulus programs, increased government spending, and decreased tax revenue caused by widespread unemployment generally account for sharp rises in the national debt. Comparing a country's debt to its gross domestic product (GDP) reveals the country's ability to pay down its debt.
By using debt instead of equity, the equity account is smaller and therefore, return on equity is higher. Another benefit is that typically the cost of debt is lower than the cost of equity, and therefore increasing the D/E ratio (up to a certain point) can lower a firm's weighted average cost of capital (WACC).
Meaning that if a company cannot pay back its debt, banks are able to take ownership of a company's assets to eventually liquidate them for cash and settle the outstanding debt. In this manner, a company can lose many if not all of its assets.
How does debt affect the cost of capital?
Higher levels of debt financing can lower the cost of capital in the short-term, but it also increases the risk of financial distress. In contrast, higher levels of equity financing can lead to a higher cost of capital in the short-term, but it also reduces the risk of financial distress.
Debt is often cheaper than equity, and interest payments are tax-deductible. So, as the level of debt increases, returns to equity owners also increase — enhancing the company's value. If risk weren't a factor, then the more debt a business has, the greater its value would be.
The debt-to-EBITDA ratio indicates how much income is available to pay down debt before these operating expenses are deducted from income. A company with a high debt-to-EBITDA carries a high degree of debt compared to what the company makes. The higher the debt-to-EBITDA, the more leverage a company is carrying.

What happens to a firm's WACC if the firm's tax rate increases? An increase in tax rate effectively decreases the cost of debt, decreasing WACC.
Additionally, WACC is just an estimate, and not all aspects of the formula are consistent. Companies take on debt, pay off loans, sell shares, buy back shares, and tax rates change. These events all affect a company's weighted average cost of capital.
Another advantage to debt financing is that the interest on the debt is tax-deductible. Still, adding too much debt can increase the cost of capital, which reduces the present value of the company.
A high WACC typically signals higher risk associated with a firm's operations because the company is paying more for the capital that investors have put into the company. 1 In general, as the risk of an investment increases, investors demand an additional return to neutralize the additional risk.
The WACC is the rate at which a company's future cash flows need to be discounted to arrive at a present value (PV) for the business. It reflects the perceived riskiness of the cash flows.
In investors' eyes, WACC represents the minimum rate of return for a company to produce value for its investors. Higher WACC ratios generally indicate that a business is a riskier investment, while a lower WACC tends to correlate with more stable business investments.
What can reduce WACC?
Optimizing your WACC can be done by reducing your cost of equity, which is determined by the risk-free rate, beta, and market return. While the risk-free rate and market return are out of your control, you can influence beta, which measures how sensitive your business is to market movements.
If the rate of return a company produces is less than its WACC, then the company is losing value for investors. If it generates higher returns than its WACC, then it is creating value for investors above its cost of capital.
Rising debt weakens economic resiliency by making it harder to respond to economic shocks and harms national security and public health by constraining our capacity to respond to and prepare for emergencies. Increased risk of a sudden fiscal crisis.
In addition to the impact to your mental health, stress and worry over debt can also adversely affect your physical health and can lead to anxiety, ulcers, heart attacks, high blood pressure and depression. The deeper you get into debt, the more likely it is that your health will be impacted.
All else being equal, the higher the debt-to-capital ratio, the riskier the company. This is because a higher ratio, the more the company is funded by debt than equity, which means a higher liability to repay the debt and a greater risk of forfeiture on the loan if the debt cannot be paid timely.
