Get more from Microsoft Excel
...with Custom Formulas, Functions and Add-ins

The problem:-  A PBMS client in the insurance industry used to spend hours preparing block quotations for new proposals received from their agents.

The solution:-  A little organisation and Microsoft Excel.  PBMS prepared a Custom function that does all the table look-ups and calculations.  The agents E-mail their lists of potential new business as Excel spreadsheets, our client copies a formula down the list - and it's done!  In seconds.

Because the Custom function is designed as an Excel add-in, it is available to all users and it's there on the menu like any native Excel formula or function.  Simple, practical and inexpensive.

A simplified example is shown below.


◄An individual date of birth...

◄...and policy renewal date...

◄ Calculates an individual premium

Any number of other premiums can be calculated by simply entering a Custom function and copying it down a list.

You can calculate at Today's date or Renewal date depending on which function you choose.

About Custom Functions...

A custom function is much like any other Excel formula - you enter the values it asks for by typing or pointing.  You can copy it like any regular formula, it even appears in the function selector on the formula bar with its own help dialog.  The difference is that it has been programmed specifically to do calculations that you use regularly.  Like the example above, it can even look up tables for you.
