Because the calculator rounds the calculated value of n up to the next higher
integer, in the preceding example it is likely that — while 328 payments will be
required to pay off the loan — only 327 full payments of $325 will be required,
the next and final payment being less than $325. You can calculate the final,
fractional, 328th payment as follows:

Final, fractional payment.
Alternatively, you could make the fractional payment together with the 327th
payment. (Doing so will result in a somewhat smaller total of all payments, since
you will not have to pay interest during the 328th payment period.) You can
calculate this final, larger, 327th payment (essentially a balloon payment) as
follows:

Final, balloon payment.
Instead of having a fractional (or balloon) payment at the end of the loan, you
might wish to make 327 or 328 equal payments. Refer to “Calculating the
Payment Amount” on page 46 for a complete description of this procedure.

You could skip this step, since 328 is already stored in the n register. If you do so, however,
you will need to press M twice in the next step (for the reason discussed in the first footnote
on page 32; you would not have to press M twice if you had not pressed 12z after w in
the example above.) We choose to show this and the following example in a parallel format
so that the procedure is easy to remember: the number you key is the number of the final
payment — either the fractional payment or the balloon payment — whose amount is to be
calculated.
