The thesis

Bitcoin isn't a gamble. It's a retirement plan.

Most retirement plans assume you put money in a system that quietly erodes your purchasing power for 30 years. Inflation eats your savings. Interest rates lag behind. You end up needing more than you planned.

Bitcoin is different. Its supply is fixed at 21 million. Its price growth follows a mathematical power law — the same pattern that describes how cities, the internet, and other networks have grown. It hasn't broken that model in 15 years.

The question isn't whether to own Bitcoin. It's how much you need, and how to stack it systematically. That's exactly what this calculator answers.

The model

This calculator uses the Bitcoin power law model — a mathematical relationship between Bitcoin's price and time that has held since 2009. The model projects a price range across three scenarios so you can plan with confidence.

The calculator gives you your target. The report gives you the roadmap.

Month-by-month DCA calendar

Exactly how much Bitcoin to buy each month, in BTC not dollars — so your commitment stays constant as price moves.

Your milestone map

Every milestone on your journey with projected dates — from your first million sats to full financial freedom.

30-year withdrawal schedule

Year by year: what you sell, what it costs in today's money, and how much stack you have left. Spoiler: you sell less Bitcoin every year.

Halving cycle strategy

When to stack hardest based on Bitcoin's four-year supply cycle — and why the math favours front-loading.

Bear / base / bull scenarios

Three price models side by side so you can plan for the realistic range, not just the number you want.

Full methodology

Every assumption explained in plain English. Power law model, inflation rate, life expectancy, spend-down logic.
