Crypto Market Cap Calculator

Market cap = current price × circulating supply. A coin at $2 with 500 million coins in circulation has a $1 billion market cap. Note that it is circulating supply, not total supply — tokens still locked in vesting contracts or a treasury are excluded.

Market cap uses only the coins in circulation today. Fully diluted valuation (FDV) prices every coin that will ever exist, including locked and unminted supply. A project with a $200M market cap but a $2B FDV has 90% of its supply still to hit the market.

There is no universal threshold, but the ratio tells you how much dilution is ahead. Above ~90% the supply story is largely settled. Below ~50% you are buying a small slice of a much larger future supply, and scheduled unlocks will keep adding sellers regardless of demand.

It can be calculated, and the comparison field above does exactly that — but market cap is not money that flowed in. Reaching a large cap requires sustained buying against every holder willing to sell on the way up, and coins with huge supplies need implausible amounts of it. Treat the figure as a ceiling check, not a target.

No. It is a price multiplied by a supply count, so a thin order book can move the whole figure by billions on modest volume. Always read market cap alongside real trading volume and liquidity depth.
