A 403b Biography, by AI

Updated: Nov 8, 2025

I asked AI (Google Gemini) to use actual 403b contribution/return data to both create a narrative and generate a chart illustrating the power of compounding.  Source of this data: a real living, breathing, retired North Carolina public school teacher.  Here’s what AI produced in 15 seconds– the delay caused by my Chromebook which cannot handle our 2 Gig fiber speeds. Side note/Internet Service hack: $70/month rate locked in for 10 years (cancellable at any time) with Lumos (T-Mobile Fiber).


Now on to the AI generated biography of this 403b...





The data vividly illustrates the transformative power of compounding interest, turning consistent, relatively small contributions over decades into a substantial final portfolio value.


A 403b Biography: The Marathon of Money

The investment journey, spanning nearly 30 years from November 14, 1994, to July 1, 2024, began with consistent, manageable contributions, often in small amounts like $50 or $100 per month (and two whole years of $0 contributed). Over this long time frame, the total amount the investor (an actual public school teacher in NC!) actually put into the account (Total Contributions) was $83,825.


At first, the growth was slow, with the portfolio value line barely inching above the contribution line. This is the foundation-building stage, where every dollar is working, but the overall market gains are small relative to the principal.


However, as the years passed, something remarkable happened. The returns earned by the portfolio began to earn their own returns. This is the power of compounding. It creates an accelerating effect where growth doesn't just happen on the principal, but on the accumulated gains as well. (The money was working harder than the teacher?)


By July 1, 2024, those  $83,825 in contributions had grown into a total Portfolio Value of $404,185.   The true measure of compounding's power is the difference:     

{Portfolio Value}   -   [Total Contributions] =  (Growth from Compounding)            

     $404,185         -          $83,825               =           $320,360


In this instance, the money earned from compounding $320,360 was nearly four times the amount the investor physically contributed--- $83,825.  The consistent, little-by-little contributions laid the groundwork, but time and compounding did the heavy lifting, turning a small, steady stream of savings into a substantial nest egg.   The End…


Clearly Gemini needs to work on its empathy/emotion algorithm—- this is simply incredible!!!


Just Imagine if the same phenomenal power of compounding was engaged in this teacher’s 457b, the spouse’s 403b, each of their Roth IRA accounts, their taxable brokerage accounts, and the 529 Plans for each of their children.  I don’t have to.  Neither do you!


Just get started! Put your money to work for you while you work, play, and sleep!  If you need help getting started, you know where to find me.


Yours in Financial Fitness,

David

P.S. For the data nerds out there, below are the teacher's downloaded statements showing the actual contributions made over 30 years.
