Paid subscribers can enter input values, save them on their computer, retrieve them later, perform actual calculations and print the calculation along with results once finalized.

Sign In Calculations for Subscribers The list of various calculations that can be performed online is provided below. We intend to expand this list further. We request as many active contributions as possible. The calculations are grouped together for the sake your convenience to locate them as quickly as possible. Please click on the active link below to enter the calculation of your interest. At present, most calculations allow for saving and retrieving the input data. Results can be seen on the calculation page itself. Calculation page along with the results can be printed off or can be converted into .pdf file by installing pdf printer on user's computer. This indeed would provide users with great operational flexibility. In future, provision will be made to be able to save the calculation results in spreadsheet format. Some of the calculations involve several intermediate steps. After completing one step, it might be required to refer to the output results and to incoprporate some of the output values into the next calculation step. Please refer to the instructions provided in the individual calculation for this purpose. Want to see the entire list of calculations?
