## Cost Of Debt

WACC is the average after-tax cost of a company’s various capital sources, including common stock, preferred stock, bonds, and any other long-term debt. In other words, WACC is the average rate a company expects to pay to finance its assets. Why do we use aftertax figure for cost of debt but not for cost of equity? There is no difference between pretax and aftertax equity costs.

• Cost of debt formula is a tool which helps one to know that loan availed is profitable for business or not as we can compare the cost of debt with income generated by loan amount in business.
• In the calculation of the weighted average cost of capital , the formula uses the “after-tax” cost of debt.
• If you have high interest payments on one or more loans, consider consolidating at a lower rate.
• Therefore, the final step is to tax-affect the YTM, which comes out to an estimated 4.2% cost of debt once again, as shown by our completed model output.

• The term debt equity could be confusing, but is basically referring to a loan.

The number of periods is used to determine how many periods of DCFs there will be before adopting the terminal value for further periods. My downloadable Excel file will calculate for up to 20 periods, even allowing for a shorter first period . In the image above, the number of periods has been set to eight . In the downloadable file, you can find this input in cell G33 of the “Pre-Tax Cost of Equity Example” worksheet. If you have more than four periods in your DCF, there’s a mathematical result from a topic called Galois theory that proves you cannot solve this formulaically (I’ll leave you to prove that!). We have to “guess” the answer, and to do that we’ll need to use Excel’s Goal Seek functionality if we are using Excel as our valuation software of choice. The current market price of the bond, \$1,025, is then input into the Year 8 cell.Some valuers will use a different discount rate for this calculation, but this is highly debatable (I will use the same rate — the WACC — throughout). The three most common assumptions are at the start, the middle, and the end of the period in question. Each assumption will obviously vary the overall valuation as a consequence. If you have ever been involved in a valuation, you will appreciate that a financial model is never far away. No matter what the technique used, access to valuation software is crucial. And Excel is probably the most common software for this purpose.

## Is Pre Tax Or After Tax Cost Of Debt More Relevant?

If the cost of debt is less than that \$2,000, the loan is a smart idea. But if it’s more, you might want to look at other options with lower interest cost. On the other hand, you might still decide to take out that loan, even if you spend more on interest than you save in tax deductions, if you need the money to grow your business. With debt equity, a company takes out financing, which could be an SBA loan, merchant cash advance, invoice financing, or any other type of financing.If you only want to know how much you’re paying in interest, use the simple formula. Simple interest is a calculation of interest that doesn’t take into account the effect of compounding. In many cases, interest compounds with each designated period of a loan, but in the case of simple interest, it does not. You can have myriad reasons for wanting to conduct this simple calculation, and you should use it whenever you feel you need to. The next piece of information you will need is your tax rate. The tax rate is a percentage that your business has to pay on your taxable income. Once you have all of those figures in front of you, you can go ahead and start to calculate the after-tax cost of the debt you have. You may have heard the term “cost of debt” at one time or another. For example, you will need to pay something other than the exact loan figure if you need to borrow money. Your loan will have an interest rate attached to it, for one.The total interest expense upon total debt availed by the company is the expected rate of return . The timing of the cash flows can be start, middle, or end, as discussed earlier. Consequently, three discount rates have been computed, as shown below. The tax delay assumption is used to build in a delay for the payment of tax.The effect of this deduction is a reduction in taxable income and resulting reduction in income tax. The reduction in income tax due to interest expense is called interest tax shield. Due to this tax benefit of interest, effective cost of debt is lower than the gross cost of debt. In the example, the net cost of debt to the organization declines, because the 10% interest paid to the lender reduces the taxable income reported by the business. The after-tax rate is more relevant because that is the actual cost to the company. I.e. once you factor in the deduction of interest payments from your tax.
