As in Example 1, it is likely that only 57
full
deposits will be required, the next and
final deposit being less than $50. You can calculate this final, fractional, 58th
deposit as in Example 1, except that for this example you must subtract the original
FV
. (In Example 1, the original
FV
was zero.) The procedure is as follows:

In this example,
M
must be pressed twice, since the preceding key pressed was
z
in RPN
mode and
}
in ALG mode. If we had stored the number of deposits in
n
(as we did
following Example 1), we would have to press
M
only once here, since the preceding key
pressed would have been
w
(as it was following Example 1). Remember that it is not
necessary to store the number of payments in
n
before calculating the amount of the final,
fractional
payment. (Refer to the preceding footnote.)
†
You might think that we could calculate the balance in the account after 57
full
deposits were
made simply by storing that number in
n
and then calculating
FV
, as we did using the second
method following Example 1. However, this balance would
not
include the interest accrued
during the 58th month.
