Where does your whole portfolio stand?
Add every purchase — bitcoin, MSTR, or a mix — and see what it's worth today next to the road not taken: what the exact same buys would be worth if they'd all gone into BTC, or all into MSTR.

Track your BTC and MSTR portfolio in one place
Most people who follow bitcoin and MSTR end up holding both, bought across many dates. A single-lot calculator can't answer the real question: given everything I've bought, where am I now — and would I have been better off picking just one? This analyzer takes your whole buy history and values it at today's live prices, then rebuilds it two more times as if every purchase had been 100% BTC or 100% MSTR.
The all-BTC line is the honest benchmark for the question "is my crypto portfolio beating bitcoin?" — if your actual mix is worth less than the all-BTC version, plain bitcoin would have served you better. The composition strip doubles as an average-cost calculator for MSTR and for BTC, showing your blended entry price per share and per coin across every buy.
Because MSTR is a leveraged bet on bitcoin, the "should I have DCA'd into bitcoin or MSTR" answer flips with your dates — MSTR has outrun BTC in bull markets and fallen harder in drawdowns. For the underlying mechanics, read the DCA into BTC vs MSTR guide and what mNAV means. It's price return only — no fees, taxes, dividends, or slippage — and it's a history tool, not financial advice.
Frequently asked
How do I track a combined BTC and MSTR portfolio?+
Enter every purchase — the date, whether it was BTC or MSTR, and the dollars invested — and the tool values them all at today's live prices. You get one number for your actual mix, plus two counterfactuals: what the same buys would be worth if every one had been 100% bitcoin or 100% MSTR. You can type rows in by hand, paste a CSV, or drop in an exchange export; everything is calculated in your browser.
Should I have DCA'd into bitcoin or MSTR?+
It depends entirely on your dates. Because MSTR is leveraged, dollar-cost averaging into it has historically beaten averaging into bitcoin during strong bull runs and lost badly in drawdowns. This tool answers it for your specific buys: enter each purchase and compare your actual result against the all-BTC and all-MSTR lines. For the mechanics of averaging into each asset over time, see the DCA guide.
How do I calculate my average cost per MSTR share or per BTC?+
The composition strip shows your blended average cost — total dollars spent on each asset divided by the units you accumulated — for both BTC and MSTR shares, alongside how many units you hold. Add all your MSTR buys (or all your BTC buys) and it works out the weighted average entry price across them.
Is my crypto portfolio beating bitcoin?+
That's exactly what the all-BTC line answers. The tool re-buys every one of your lots as if it had gone into bitcoin on the same date, then compares that total to your actual mix at today's price. If your actual value is higher, you're ahead of just holding BTC; if it's lower, plain bitcoin would have done better.
Do you store my transactions?+
No. All parsing and computation happen client-side in your browser — no transaction row, file, or portfolio is ever sent to a server, stored in a database, or logged. There is no account, no login, and no email or exchange connection of any kind. Your portfolio is saved only to this browser's local storage, and the 'Clear my data' button wipes it instantly.
