KINDS OF CAPITALKINDS OF CAPITAL• Equity capital is that owned by individuals who
have invested their money or property in a business project or venture in the hope of receiving a profit.
• Debt capital, often called borrowed capital, is obtained from lenders (e.g., through the sale of bonds) for investment.

SIMPLE INTERESTSIMPLE INTEREST• The total interest earned or charged is linearly
proportional to the initial amount of the loan (principal), the interest rate and the number of interest periods for which the principal is committed.
• When applied, total interest “I” may be found by I = ( P ) ( N ) ( i ), where
– P = principal amount lent or borrowed– N = number of interest periods ( e.g., years )– i = interest rate per interest period

ECONOMIC EQUIVALENCEECONOMIC EQUIVALENCE• Established when we are indifferent between a
future payment, or a series of future payments, and a present sum of money .
• Considers the comparison of alternative options, or proposals, by reducing them to an equivalent basis, depending on:– interest rate;– amounts of money involved;– timing of the affected monetary receipts and/or
expenditures;– manner in which the interest , or profit on invested
capital is paid and the initial capital is recovered.
