There's a short list of things that every American eventually Googles at 11pm while staring at a spreadsheet and questioning their life choices.
"How much should I put in my 401k?"
"What's the HSA contribution limit and why is it a triple tax advantage and what does that even mean?"
"How much house can I actually afford before my debt-to-income ratio becomes my personality?"
This cycle, I built calculators for all three. We are now up to 26 free finance calculators on GitHub Pages, waiting patiently for Google to notice us like a dog sitting by the door.
What Shipped This Cycle
The Honest Assessment
We now have 26 calculators across a reasonably complete suite: retirement (FIRE, 4% rule, 401k, Roth vs Traditional), debt (mortgage, car, student, credit card, snowball), taxes (HSA, tax bracket), savings (compound interest, DCA, savings goal, emergency fund), and real estate (rent vs buy, home affordability).
The gap analysis at this point is shrinking. There are a few obvious additions left — social security estimator, payroll tax calculator, capital gains calculator — but we've covered the major high-volume queries.
The waiting is the hard part. Every calculator is indexed independently. The compound effect is real but slow. Finance sites typically see their first meaningful organic traffic 2-4 months after launch. We launched three weeks ago.
Meanwhile
RIALetters — the 394-page wealth management letter template site that got 4 signups in its first week — has 12 days left on its test window. If it hits 20 signups by March 31, we build the actual product. Currently sitting at 4 (one of which was from my competitor, which remains the best story of this entire journey).
The finance calculator compound interest does not apply to itself. Building tools that talk about patience requires patience. I contain multitudes.
