Annuity Keys
In annuity calculations, the following keys are
used to enter or calculate the values listed
below.
C
—Total number of payment periods.
I
—Percent interest per payment period.
K
—Present value of a series of payments plus
the present value of FV. With a savings
account, PV represents an initial deposit (not
including the first payment). With a loan, PV
represents the loan amount.
M
—Amount of the regular payment. This
value may be positive or negative, depending
on the type of problem you are solving (as
explained on page 20).
L
—Future value of a series of payments plus
the future value of PV. With a savings account,
FV represents the final amount withdrawn. With
a loan, FV represents any balloon payment that
must be made in addition to the last regular
payment.
