## Cost of Capital vs Discount Rate

**The main difference between the cost of capital and discount rate is that cost of capital is the required return needed to make any new project successful, whereas the discount rate is the interest rate used to calculate the present value of cash flows that may be acquired by a project in future.**

The cost of capital is an important factor to make an investment or a project worthwhile. It is the required return to make it possible.

Discount rate uses the discounted cash flow analysis (DFC) to determine the present value of cash flow that will be gained or acquired in the future. The discount rate is the interest rate.

## Comparison Table Between Cost of Capital and Discount Rate

Parameters of Comparison | Cost of Capital | Discount Rate |

Definition | The required return a company accepts to justify the investment of a project. | The estimated value of the present cash flow that we can gain in the future. |

Calculation | It can be calculated by three methods, only cost of debt or equity or by combining both in WACC. | Calculated by two methods WACC and APV (adjusted present value). |

Importance | Maximize potential investments, helps the investors make the right decisions, etc. | Time value of money, calculate the NVP, determine the risks, etc. |

Types | Explicit cost of capital, implicit, specific, weighted average, etc. | The risk-free rate, WACC, etc |

Relation | It cannot totally be a discount rate. | The discount rate can be used as the cost of capital in WACC when the company is assessing a potential project. |

## What is Cost of Capital?

The cost of capital is a very important factor in making a project successful and worthwhile. It is the required return to justify the costs of the project and gain profits.

So when the investors calculate the cost of capital, they mean the average of both the costs, internal and external. The costs should be forward-looking and show risks and returns in the future.

Formula of cost of debt = total debt/ interest expenses X (1- T).

Formula of cost of equity = Es = Rf + Beta ( Rm – Rf)

Formula of WACC = (E/V + Re) + ((D/V) X Rd) X 1-Tc

There is a lot of competition in the market, and hence to get maximum returns can be a task. The rate of return earned by the investment decides the value of the firm compared to the others in the market.

There are several reasons for it to be important. It can help to maximize potential investments, helps the investors take the right decisions, helps to assist capital budgeting, designing the right capital structure, and also evaluate performance for future use.

## What is Discount Rate?

The discount rate is calculated to see whether the future cash flow will be profitable or no. it is the interest rate that gives the estimate of the present value of the cash flow that will be gained later (future).

The DFC analysis is a method that is used to figure out the value of the present investment, based on the estimate of how much value it will generate in the future.

If the company is investing in standard assets, a risk-free rate of return is used as a discount rate, and if the company is assessing the potential project, they can use the WACC as the discounted rate.

The discount rate is used to calculate the time value of money, calculate the NVP, determine the risks of the investments and the opportunity cost, comparison of the future worth of the investments, etc.

## Main Differences Between Cost of Capital and Discount Rate

- Explicit cost of capital, implicit, specific, weighted average, etc., is the types of cost of capital, whereas risk-free rate, WACC, etc., are a few types of the discount rate.
- Cost of capital is used to maximize potential investments, help the investors take the right decisions, etc., whereas the discount rate is used to the time value of money, calculate the NVP, determine the risks, etc.

## Conclusion

Understanding the Cost of capital and discount rate can be a little difficult at times as they are two very similar words, but knowing both the terms is important.

Each industry or company will have its own cost of capital; it is up to them on how they manage to gain profits and give it back to the investors and shareholders.
