What the $2.5 Million Was Hiding

The Late Starter · September 12, 2026

A few years ago, I came across a textbook my son used in a Finance program run by his church. It had a famous example from Ramsey Education’s personal finance curriculum. The names were Jack and Blake.

Jack starts investing at 21. $200 a month, for nine years. At 30, he stops completely. Total invested: $21,600. And he just leaves it alone.

Blake starts investing at 30 — the exact age Jack stopped. He keeps putting in $200 a month for the next 38 years, almost his entire working life, all the way to 67.

Assume both get an 11% annual return. Who ends up with more at 67?

Jack does. By a landslide. He put in just nine years and a total of $21,600, and by 67 he has about $2.5 million — precisely $2,547,159. Blake, despite investing far more ($91,200 over 38 years), never catches up. He ends up at about $1,483,033.

A convincing graph

The first time I saw this graph, I found it pretty convincing. Looking at decades of market data, it’s not an unreasonable story. Slowdowns happen, unexpected crises happen, markets swing — but historically they’ve recovered, and innovation hasn’t stopped. So the lesson — “start early and a little goes a long way” — seemed like a great way to teach kids the power of compounding.

So I told this story to my own kids more than once. “Start early, and you won’t have to work as hard to catch up later the way I did as a late starter.” And I let myself relax. My kids had started putting something away, even if modestly, in their twenties — and I figured that alone meant retirement was, to some degree, handled.

The one thing I missed

Recently, revisiting these numbers, I realized I had completely missed something.

That $2,547,159 is a nominal figure, 47 years out — sometime around 2073. It says nothing about how much prices will have risen over those 47 years.

So I ran the numbers. What is $2,547,159, 47 years from now, actually worth in today’s dollars?

Historically, the long-run average inflation rate in the U.S. has been close to 3%. In other words, behind the headline “$2.5 million at 67” was a much more modest picture: roughly $634,000 in today’s purchasing power.

$2.5 million and $634,000. Neither number is wrong — but I had never once looked at the gap between them.

That doesn’t make the story wrong

I don’t want this to be misread. The core lesson of Jack and Blake — that money invested early beats money invested later, thanks to compounding — still holds. The fact that Blake never catches up despite contributing far more has nothing to do with inflation; both of them are affected by it equally.

What I missed wasn’t the principle of compounding. It was that I had never once converted that final number into today’s value. I saw “$2.5 million” and simply assumed it meant “we’re set.”

Where I’ve landed

Here’s how I’ve reframed this for myself.

First, starting early is still the right call. Jack’s story still proves that time is the single most powerful ingredient in compounding. I’ll keep telling my kids to start early.

Second, always translate the number into today’s value. If you set a retirement target based on a nominal figure alone, it’s easy to under-save while believing you’re “done.” (If you’re curious what your own target number should look like, this blog’s Retirement Savings Goal Calculator is worth a few minutes.)

Third, don’t stake everything on one big number decades out. Betting your entire retirement on a single 47-year compounding curve is too risky. Retirement accounts like a 401(k)/IRA, other forms of investing, and — where possible — income that continues into retirement: building two or three layers of cash flow is a much safer position against the variable that inflation represents.

I’d let myself feel settled by that $2.5 million figure. Running the numbers again was a good wake-up call. If you’re resting on a similarly large number decades away, the inflation calculator below is worth a try — it might show a different picture than you expect.
