payments. Suppose that we use 24 periods in the first line of the amortization

screen, i.e., 24 @@OK@@. Then, press @@AMOR@@. You will get the following

result:

This screen is interpreted as indicating that after 24 months of paying back the

debt, the borrower has paid up US $ 723,211.43 into the principal amount

borrowed, and US $ 215,963.68 of interest. The borrower still has to pay a

balance of US $1,276,788.57 in the next 36 months.

Check what happens if you replace 60 in the Payments: entry in the

amortization screen, then press @@OK@@ @@AMOR@@. The screen now looks like this:

This means that at the end of 60 months the US $ 2,000,000.00 principal

amount has been paid, together with US $ 347,937.79 of interest, with the

balance being that the lender owes the borrower US $ 0.000316. Of course,

the balance should be zero. The value shown in the screen above is simply

round-off error resulting from the numerical solution.

Press $or `, twice, to return to normal calculator display.
