The Pralana Retirement Calculator operates on your local computer using Microsoft Excel and is available in two versions. The Gold version sells for $99 and is a high-fidelity financial model designed for personal use.  You can learn more by visiting the Pralana Gold page of our website and you can get a free download of its extensive user manual to learn even more.  The free Bronze version is specially made for the person who desires to go beyond a quick-and-dirty financial analysis but prefers a simple, easy-to-use design.

A Pralana Gold license entitles you to free support via e-mail and all updates of the 2020 model.

Pralana Gold 2019 licensees can login and upgrade for $49. Anyone who made a full-price purchase of PRC2019 on or after September 20, 2019 is entitled to a free upgrade to PRC2020 and can login as a 2020 Gold licensee using their 2019 Gold user id to get the free download.

* 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.

* Note for Internet Explorer 11 users on Windows 10 machines: PRC downloads may fail to work with this configuration.  The workaround is as follows: On the IE11 page, go to Tools (the cog in the upper right corner), then Safety, then “Turn Off Windows Defender SmartScreen”. You can then turn this back to the “On” state when the download is completed.
