The Nature of the Pralana Retirement Calculator

PRC is a file that operates on Microsoft’s Excel and can be run with all Excel menus hidden.  While it’s running, you will hardly be aware that you’re using Excel.  PRC is highly dependent upon macros but PRC macros are digitally signed* by Pralana Consulting LLC to eliminate any security-related concerns you may have.  The PRC file self-registers itself to the computer it is downloaded to and cannot be moved or copied to another computer thereafter without the specific assistance of Pralana Consulting LLC.

System requirements:

Option 1:  A Windows platform running Excel 2007 or later (Excel 2007 and 2010 users, please see the note at the bottom of this page)

Option 2: A Mac system running at least O/S 10.5 and Excel 2011 for Macs

Option 3: A Mac system configured with the Parallels Desktop (or an equivalent program for supporting Windows applications), Windows and Windows Excel 2007 or later.

PRC2017/Gold sells for $99.  This entitles you to support via e-mail and all PRC2017/Gold updates.  You can view the PRC/Gold Change Log to see the changes made since PRC2016.  PRC2016/Gold license holders can upgrade for $33 after logging in via the User Support page (upgrades are free for anyone who purchased or upgraded to PRC2016 after August 15 and prior to January 6).

PRC2015/Silver sells for $8.95 and this entitles you to support via e-mail and all PRC2015/Silver updates. You can view the PRC/Silver Change Log to see a brief description of all changes made since the initial release of PRC/Silver.

PRC2015/Bronze is FREE and can be moved from one computer to another.  Due to the high degree of similarity to PRC2015/Silver, it does not have its own user manual; the Silver User Manual should be used as a reference and will be accurate with few exceptions.

Please visit the User Support page for a detailed description of PRC support processes, including access to the user manuals, getting updates and performing license renewals.

* Note for Excel 2010 Users: Your Excel configuration needs to include Microsoft Service Pack 2 (SP2). Without this, Excel may tell you that the PRC file is corrupted.

* Note 1 for Excel 2007 Users: Your Excel configuration needs to include Microsoft Service Pack 3 (SP3).  Without this, Excel may tell you that the PRC file is corrupted.

* Note 2 for Excel 2007 Users: The digital signature is not recognized by Excel 2007 and will be reported as an invalid signature.  This is due to the fact that Excel 2007 has not been maintained by Microsoft since 2012 and is no longer compatible with the newer security software technology used to produce the Pralana Consulting LLC digital signature.  The workaround is to create a new folder on your Windows system into which you place the PRC file.  Then, via Excel’s Trust Center, you specify this folder as a Trusted Location.

PRC2015/Bronze - FREE (please be aware that this product will be replaced with a new model in the near future.  Sign up for our newsletter or check back frequently for details).
