Bitcoin & MSTR fundamentals
Drag a slider, or type into any field below, to explore a scenario — Bitcoin price, mNAV, and the six fundamentals below all update the model live until you do.
Cash earmarked to cover debt and preferred stock payments — added to the total Bitcoin backing, partially counteracting what debt and preferred subtract from it.
General-purpose liquidity — not earmarked for debt/preferred payments the way USD Reserve is, but added back to the total Bitcoin backing the same way.
Pure Bitcoin-backed asset value — before the market's premium (mNAV) is applied.
Net value/share × mNAV — what the model estimates MSTR should actually trade at.
What MSTR is really trading at — for comparison against the model's estimate.
Volatility & rate
IV varies by strike and expiration — 84% is just a starting assumption. If you have a brokerage account, check its live quote for your exact contract. If not, look it up free on Yahoo Finance ↗ (no account needed) or Barchart ↗ (account required).
Enter the option's quoted price per share — the number your broker or options chain shows before multiplying by the 100-share contract size, e.g. "$22.50," not "$2,250." This back-solves the IV that produces it and shows how closely today's model assumptions track the real price.
⚠ Strike or expiry changed from defaults — IV may not match your contract due to volatility skew. Use the calibration tool above with your contract's current market price.

Your Saved Positions
Save the exact scenario currently set above — strike, expiry, BTC price, mNAV, IV, and the computed results — to come back to later.
Compared at today's live BTC price and Strategy's current fundamentals (BTC held, shares, debt, and reserves) — only each scenario's saved strike, expiry, mNAV, and IV stay fixed as the assumption being tested.
This mirrors Strategy's own published capital-structure accounting: common shareholders have a residual claim on the Bitcoin treasury, standing behind both convertible debt and the STRK/STRF/STRD/STRC preferred stack. Earlier versions of this tool only netted out convertible debt, which overstated fair value per share by roughly 30% at current prices.
The derived MSTR price is then net value per share × mNAV multiple. Option pricing uses Black-Scholes as a European-style approximation for MSTR's American-style calls — early exercise is rarely optimal for a non-dividend-paying stock, so the approximation is close in practice.
Disclaimer
This tool is for educational and informational purposes only. It uses the Black-Scholes model, which is designed for European-style options; MSTR calls are American-style, so actual market prices may differ. MSTR price is derived from BTC holdings and a user-supplied mNAV multiple — this is a model assumption, not a prediction. Implied volatility for long-dated, deep out-of-the-money contracts is illiquid and can vary meaningfully from theoretical values — check a live quote where possible. Nothing here constitutes financial advice. Do your own research.
