Annuity Calculations
For annuity calculations, use
2
to set the
calculator to financial mode (
FIN
appears in the
display).
An annuity is a series of equal payments made
at regular time periods with interest calculated
at the end of each period. Ordinary annuities
have end-of-period payments; annuities due
have beginning-of-period payments.
0 a
(Beginning-of-Period)
—Sets the
calculator to compute for annuity-due problems
(beginning-of-period payments).
Pressing
0 a
causes
Begin
to appear in
the display. The beginning-of-period function is
in effect until you cancel it (by pressing
0 a
again) or leave the financial mode.
§
When
Begin
is in the display, the calculator
solves using beginning-of-period payments.
§
When
Begin
is not in the display, the
calculator solves using end-of-period
payments.
Note:
If an annuity problem does
not
use
beginning-of-period payments, be sure that
Begin
is not in the display before you compute
the answer. Having
Begin
in the display has no
effect on compound interest calculations in
which no payment is involved.
