Analyzing Business Capital Costs and Investment Metrics

A. Cost of Equity Financing (Partner Resources)

The contributions of partners or reservations do not impose a commitment on the company to pay a specific interest or dividend. Calculating these costs can be difficult. A partner in a company, either through acquiring shares at creation or purchasing listed shares, assumes a very high risk, expecting a return that compensates for this risk. In any case, these resources carry an opportunity cost to the extent that the profitability achieved using them within the enterprise must be higher than what is achieved using these resources externally.

B. Cost of External Resources (Medium and Long Term)

There is always a contract specifying the loan conditions, including the interest to be paid. To calculate the Annual Percentage Rate (APR), one must account for associated costs, commissions, etc.

C. Cost of Short-Term Debt Capital

Among short-term financial sources, one must differentiate between spontaneous and negotiated sources.

• Spontaneous sources, such as worker wages and supplier credits, often represent resources with a cost of zero.
• Other resources incur a cost dependent on the agreed-upon terms.

D. Weighted Average Cost of Funds (WACC)

To determine the average cost of resources utilized by the company, one can calculate a weighted average of the different costs. The weights used are the percentages that each funding source represents relative to the total resources employed. The lower the average cost, the greater the number of profitable investments the company can undertake, meaning those that generate a profit.

Characteristics of an Investment

Key elements defining an investment include:

a) Initial Outlay

This is represented by $C$ and is the amount paid at the time of acquiring the assets. Time 0 usually corresponds to the largest payment.

b) Duration of the Investment

This is the number of years, represented by $n$, during which cash inflows and outflows are expected to occur.

c) Net Cash Flows and Quasi-Rents

These are represented by $F_i$ and signify the difference between collections ($C_i$) and payments ($P_i$) that the company experiences over the $n$ periods of the investment. These flows are the difference between receipts and payments, not income and expenditure.

d) Residual Value

This is the value of the asset at the end of the investment's life ($q$). This value can be zero if the asset has no market acceptance.
