c. Enter partial derivative infonnation before trying again.

Using the financial solver

Use the financial solver to perfonn time-value-of-money calculations, and

to calculate amortization amoimts that relate to these calculations.

• Time-value-of-money calculations relate to a borrowed amoimt of

money that is to be repaid, at a fixed compounding interest rate, over a

period of time.

• Amortization is the way the repayments are divided between the

principal amount and interest on the loan.

The financial solver allows you to calculate any one of the parameters for

a time-value-of-money transaction. You can perfonn modelling by entering

all parameters except one, and calculating the value for the missing one.

TIme-value-oF-money calculation parameters

The financial solver uses the following parameters:

P/oYR

PMT

BEG/END

The total number of compoimding interest periods and

payments. A compoimding interest period is the period

after which the amoimt of interest that the loan has accrued

is added to the principal. The financial solver assumes that

this period corresponds to the payment period.

The annual interest rate, expressed as a nominal

percentage.

The value of the loan at the beginning of the first period.

The periodic payment amoimt, or the repayment amount

that is to be made in each period.

The value of the loan at the end of the period. For

example, if you were calculating details of a complete loan

repayment, this value would be 0.

Whether the payment is made at the beginning or end of the

payment period.
