Finance app functions

The Finance app uses a set of functions that all reference the same set of Finance app variables. These

correspond to the elds in the Finance app Numeric view. There are 5 main TVM variables, 4 of which are

mandatory for each of these functions, as they each solve for and return the value of the fth variable to two

decimal places. DoFinance is the sole exception to this syntax rule. Note that money paid to you is entered

as a positive number and money you pay to others as part of a cash ow is entered as a negative number.

There are 3 other variables that are optional and have default values. These variables occur as arguments to

the Finance app functions in the following set order:

●

NbPmt—the number of payments

●

IPYR—the annual interest rate

●

PV—the present value of the investment or loan

●

PMTV—the payment value

●

FV—the future value of the investment or loan

●

PPYR—the number of payments per year (12 by default)

●

CPYR—the number of compounding periods per year (12 by default)

●

BEG—payments made at the beginning or end of the period; the default is BEG=0, meaning that

payments are made at the end of each period

The arguments PPYR, CPYR, and BEG are optional; if not supplied, PPYR=12, CPYR=PPYR, and BEG=0.

CalcFV

Solves for the future value of an investment or loan.

CalcFV(NbPmt,IPYR,PV,PMTV[,PPYR,CPYR,BEG]

Example:

CalcFV(360, 6.5, 150000, -948.10) returns -2.25

CalcIPYR

Solves for the interest rate per year of an investment or loan.

CalcIPYR(NbPmt,PV,PMTV,FV[,PPYR,CPYR, BEG])

Example:

CalcIPYR(360, 150000, -948.10, -2.25) returns 6.50
