You hit $100K in
The first $100K is the slowest — after that, compounding does more of the lifting every year. I documented every step of mine, from $5 of Starbucks stock to six figures, in THE FIRST $100K — the exact playbook.

The climb

Year-by-year detail

The fine print, honestly. Returns are assumed steady — real markets lurch, dip and recover, so your actual path will be bumpier than this chart (mine was). The maths still holds over long periods, which is the whole point. Contributions are assumed monthly and the return compounds monthly. Inflation isn’t modelled: $100K in ten years buys less than $100K today, so if anything, start bigger and start sooner.

How to use this calculator

Enter what you have, what you can add monthly, and a return assumption. The calculator shows the date you hit your target, how much of it you contributed versus earned, and stars each quarter-milestone along the way.

Play with the monthly amount — it dominates early. The return barely matters in year one; the savings rate is everything until compounding takes over.
