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

fields 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

fifth 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 flow 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
