Welcome to

— a platform designed to help you understand why Bitcoin through dynamic calculators and mathematical models. Since not everyone is a huge nerd like us, we’ve built simple, intuitive calculators that require only basic inputs to generate accurate, data-driven models. These models provide key insights into how Bitcoin impacts everyday financial scenarios.
At its core, this site is all about math and numbers—because if people don’t grasp the fundamentals of money, investing, loans, inflation, and other financial metrics, how can they make the best decisions for their future? While financial advisors (which we are not) exist to guide people, that industry is often behind the curve. So, we created tools, data, and resources to empower you to see the bigger picture behind Why Bitcoin.


For those looking to expand their knowledge, our Education & Entertainment section features a curated collection of Bitcoin-related documentaries, books, podcasts, X (formerly Twitter) accounts, and tools aimed at helping you explore Bitcoin’s role as a digital asset. Additionally, we’ve compiled a selection of Bitcoin-related Tools & Services that some may find useful for deepening their engagement with Bitcoin or learning more about its applications.

One of Bitcoin’s most important attributes as a wealth preservation asset, store of value, and hedge against fiat debasement is its unmatched Compound Annual Growth Rate (CAGR)—covered in more detail below.
What Is CAGR?
CAGR (Cagg-Err), or Compound Annual Growth Rate, is a metric used to measure the annualized rate of return of an investment over a specific period, assuming profits are reinvested each year. It smooths out fluctuations to show what the steady growth rate would have been, even if the actual returns varied year-to-year. Michael Saylor, a well-known advocate of Bitcoin, has publicly discussed potential scenarios for Bitcoin's growth over the next 21 years, suggesting a range of annualized growth rates: a conservative scenario (bear case) of 21% compounded annually, a base case of 29%, and an optimistic scenario (bull case) of 37%. These are his personal perspectives and are not guaranteed outcomes.


At Bitcoinmath.org, Bitcoin’s CAGR is an adjustable variable in every calculator we provide. You can explore different scenarios by increasing or decreasing this rate to see how it influences hypothetical outcomes. Feel free to experiment with various growth rates and timeframes to align with your own perspectives or to better understand how different assumptions about Bitcoin’s future might play out. Remember, these tools are purely educational and meant to help you explore concepts, not to predict or guarantee future performance.
