After developing this calculator, I was privileged to locate a copy of the excellent Guide to The Maaser Form by Rabbi Yechezkel Feldberger in conjunction with Nachum Blumenfrucht, CPA. The Maaser Form is available from the Chicago Community Kollel and generally agrees with the piskei halacha brought herein.
