Bitcoin market cap calculator
Enter a Bitcoin price to see the market cap it implies, or work backwards from a target market cap to the price per coin. Every result comes with three plain-language comparisons, so a trillion-dollar number actually means something.

How to use this calculator
The calculator runs in two directions. Pick a mode, enter a value, and press Calculate.
- Price → Market cap — type a Bitcoin price and see the total market cap it would imply. Try a round number like $1,000,000 per coin.
- Market cap → Price — type a target market cap, or choose an asset from the list to match its value, and see the price one bitcoin would need to reach.
Under every result, the That is approximately panel places the figure next to three familiar reference points, so a number with twelve zeros turns into something you can picture.
How Bitcoin’s market cap is calculated
Market cap is price multiplied by circulating supply:
Market cap = Bitcoin price × coins in circulation
The number of coins in circulation is not fixed. New bitcoin enters the supply with each block, and the pace halves every 210,000 blocks. This calculator reads the live block height and computes the exact circulating supply from Bitcoin’s issuance schedule, rather than rounding to a flat figure. Today that is close to 20 million coins, climbing slowly toward the 21 million cap.
Using circulating supply, rather than the full 21 million, matches how market cap is reported everywhere else. It also means a “price to match gold” answer lands a little higher than it would if you assumed every coin were already mined.
What the comparisons mean
The three comparisons under each result are drawn from a mix of reference points: precious metals, the largest public companies, entire stock markets, national economies, and money supply. The Bitcoin price and the gold value update live. The rest are curated from public sources and carry the date they were last checked, so you always know how fresh a figure is.
One caveat matters. A market cap is a stock, a single snapshot of total value. A country’s GDP is a flow, the output of a whole year. Putting them side by side is useful for scale, which is why the panel flags it, but the two are not the same kind of measurement.
Why compare Bitcoin to gold, stocks, and GDP
Bitcoin is often described as digital gold, and the comparison is the clearest way to size up where it could go. Gold’s above-ground stock is worth in the low tens of trillions of dollars. Matching it is the “flippening” that Bitcoiners talk about, and this calculator shows the exact price per coin that milestone would take.
The same logic scales up and down. A market cap the size of Apple, or the entire S&P 500, or a mid-sized national economy each corresponds to a specific Bitcoin price. Seeing that price makes an abstract target concrete, and it cuts both ways: some milestones are closer than they feel, and some are far larger than a headline number suggests.
Frequently asked questions
What is Bitcoin's market cap?
Bitcoin's market cap is the total value of every bitcoin in circulation. It is the current price of one bitcoin multiplied by the number of coins that have been mined so far, which is about 20 million today and rises slowly toward the 21 million cap. It is the standard way to compare Bitcoin's size to other assets, companies, and asset classes.How is Bitcoin's market cap calculated?
Market cap equals price times circulating supply. This calculator takes the price you enter, multiplies it by the live circulating supply (computed from the current block height), and shows the result. Switch to the second mode and it runs the division in reverse: a target market cap divided by the circulating supply gives the implied price per coin.What would Bitcoin's price be if it matched gold's market cap?
Pick "Market cap → Price" and choose gold from the asset list. The calculator sets the target to gold's live market cap (its above-ground stock priced at the current spot rate) and divides by the circulating supply to show the price one bitcoin would need to reach. Because it uses today's circulating supply rather than the full 21 million, the implied price sits slightly higher than the all-coins-mined version.Does the calculator use circulating supply or 21 million?
It uses the live circulating supply, roughly 20 million coins today, computed from the current block height. That reflects the market cap as it is actually measured right now. The remaining coins are released gradually through mining until issuance ends around the year 2140.Are the comparison figures exact?
The Bitcoin price and gold price update live. The other reference points, national GDP, company valuations, money supply, and asset-class totals, are curated from public sources with the date shown and refreshed periodically. They move over time, so treat each comparison as a well-sourced approximation for scale, not a to-the-dollar figure.
