lThere are seven TVM variables:

TVM calculations: Another example

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

Variable Description

N The 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.
