This financial calculator was developed by me around 1997. The financial registers at left work mostly the same as in a HP 12C calculator, even regarding the "n" rounding. Each financial register matches the button at its right. For example, fill the PMT register if you know value of payment, or fill the other registers and press PMT if you want to calculate PMT.
The yellow registers are also used to feed the other arithmetic operations, whose results will appear at the blue register.
BEGIN: If enabled, the first payment is made at the beginning of the period. Matches the "begin" flag in HP 12C. It is important for calculations that involve non-zero PMTs.
CFP: If enabled, the fractionary part of "n" will be calculated as compound interest (more fair but not often used).
The .class files that run in this page were compiled with gcj (Java compiler of the GNU GCC suite). We used gcj because in our experience it generates the most compatible .class, regarging to different browser and JVM versions.
