THE TIME VALUE OF MONEY
• Most valuable things concerned are: rate of interest, discount rate, cost of
capital.
• FV(rate, number of periods, payment, present value, type) Computes the
future value of a series of equal payments and/or a present value after a
specified number of periods at a specified rate of interest.
• PV(rate, number of periods, payment, future value, type) Computes the
present value of a series of equal payments and/or a future value after a
specified number of periods at a specified rate of interest.
• NPV(rate, value1, value2,…) Computes the present value of a series of
future cash flows (value1, value2, …) at a specified rate of interest.
• PMT(rate, number of periods, present value, future value, type) computes
the value of a series of equal payments equivalent to a given present value or
future present value for a specified number of periods at a specified rate of
interest.
• PPMT(rate, period, number of periods, present value, future value, type)
• IPMT(rate, period, number of periods, present value, future value, type)
These two functions compute the amounts of a payment to principal (PPMT)
and to interest (IPMT) during a given period.
• CUMPRINC(rate, number of periods, present value, start period, end
period, type)
• CUMIPMT(rate, number of periods, present value, start period, end period,
type)
• NPER(rate, payment, present value, future value, type)
• RATE(number of periods, payment, present value, future value, type, guess)
