Arguments
cost
The initial cost.
salvage
The value at the end of the depreciation.
life
The number of periods in the depreciation cycle.
period
The length of the period, in the same units as life.
factor
An optional number that is the rate at which the balance declines. The default value is 2.
Note
This function is equivalent to the Excel function DDB.
Future Value(rate, nper, pmt, <pv>, <type>)
Description
Returns the future value of an investment that is based on periodic, constant payments and a constant interest rate.
Arguments
rate
The interest rate.
nper
The number of periods.
pmt
The constant payment.
pv
An optional number that is the present value. The default value is 0.
type
An optional switch. 0 specifies end-of-period payments, and 1 specifies beginning-of-period payments. The default value is 0.
Note
This function is equivalent to the Excel function FV.
Interest Payment(rate, per, nper, pv, <fv>, <type>)
Description
Returns the interest payment for a given period for an investment that is based on periodic, constant payments and a constant interest rate.
Arguments
rate
The interest rate.
per
The period for which you want the interest.
nper
The total number of periods.
pv
The present value.
fv
An optional number that is the future value. The default value is 0.
type
An optional switch. 0 specifies end-of-period payments, and 1 specifies beginning-of-period payments. The default value is 0.
Note

Interest Rate(nper, pmt, pv, <fv>, <type>, <guess>)
Description
Returns the interest rate per period of an annuity.
Arguments
nper
The total number of periods.
pmt
The constant payment.
pv
The present value.
fv
An optional number that is the future value. The default value is 0.
type
An optional switch. 0 specifies end-of-period payments, and 1 specifies beginning-of-period payments. The default value is 0.
guess
An optional number that is what you think the rate will be. The default value is 0.1 (10%).

This function is equivalent to the Excel function RATE.
Internal Rate of Return(values, <guess>)
Internal Rate of Return(guess, value1, value2, ...)
Description
Returns the internal rate of return for a series of cash flows in the values argument.
Arguments
values
A one-dimensional matrix of values. If the second form of the function is used, list each value separately.
guess
The number that you think is near the result. The default value is 0.1 (10%).
Note
This function is equivalent to the Excel function IRR.
Modified Internal Rate of Return(values, finance rate, reinvest rate)
Modified Internal Rate of Return(finance rate, reinvest rate, value1, value2, ...)
Description
Returns the modified internal rate of return for a series of periodic cash flows. The cost of investment and the interest received on reinvested cash is included.
Arguments
values
A one-dimensional matrix of values. If the second form of the function is used, list each value separately.
finance rate
The interest rate that you pay on the money in the cash flows.
reinvest rate

Note
This function is equivalent to the Excel function MIRR.
Net Present Value(rate, values)
Net Present Value(rate, value1, value2, ...)
Description
Returns the net present value of an investment by using a discount rate and a series of future payments (negative values) and income (positive values).
Arguments
rate
