There are seven TVM variables:

Variable Description

NThe total number of compounding periods or payments.

I%YR	The nominal annual interest rate (or
	investment rate). This rate is divided by the
	number of payments per year (P/YR) to
	compute the nominal interest rate per
	compounding period. This is the interest
	rate actually used in TVM calculations.
PV	The present value of the initial cash flow.
	To a lender or borrower, PV is the amount
	of the loan; to an investor, PV is the initial
	investment. PV always occurs at the
	beginning of the first period.
P/YR	The number of payments made in a year.
PMT	The periodic payment amount. The
	payments are the same amount each
	period and the TVM calculation assumes
	that no payments are skipped. Payments
	can occur at the beginning or the end of
	each compounding period—an option
	you control by un-checking or checking
	the End option.
C/YR	The number of compounding periods in a
	year.
FV	The future value of the transaction: the
	amount of the final cash flow or the
	compounded value of the series of
	previous cash flows. For a loan, this is the
	size of the final balloon payment (beyond
	any regular payment due). For an
	investment, this is its value at the end of the
	investment period.

Suppose you have taken out a 30-year, $150,000 house mortgage at 6.5% annual interest. You expect to sell the house in 10 years, repaying the loan in a balloon
