Market Cap Calculator
Instantly calculate a cryptocurrency's market capitalization by multiplying its current price by the circulating supply. Use this when comparing the relative size of different crypto assets or tracking a coin's dominance in the market.
About this calculator
Market capitalization is the most widely used metric to gauge the overall size and value of a cryptocurrency. It is calculated with the formula: Market Cap = Price × Circulating Supply. For example, if a coin trades at $2.50 and has 400 million coins in circulation, its market cap is $1 billion. Circulating supply refers only to the coins currently available and tradable in the market — it excludes locked, reserved, or un-mined tokens. A higher market cap generally signals a more established asset with greater liquidity, while a low market cap coin may offer higher growth potential but carries more volatility. Comparing market caps helps investors categorize coins as large-cap, mid-cap, or small-cap assets.
How to use
Suppose you want to find the market cap of a token priced at $3.75 with a circulating supply of 500,000,000 coins. Enter $3.75 in the Current Price field and 500,000,000 in the Circulating Supply field. The calculator applies: Market Cap = $3.75 × 500,000,000 = $1,875,000,000. This means the token has a market capitalization of approximately $1.875 billion, placing it in the large-cap category. You can repeat this for any coin to quickly compare sizes across the crypto landscape.
Frequently asked questions
What is the difference between market cap and fully diluted valuation in crypto?
Market cap uses only the circulating supply — coins currently available to trade — while fully diluted valuation (FDV) uses the maximum total supply that will ever exist. FDV gives a worst-case dilution scenario if all coins were released today. For coins with large locked or future supplies, FDV can be dramatically higher than market cap. Comparing both figures helps investors understand potential inflation risk in a token's long-term economics.
Why does a cryptocurrency's market cap change even when no new coins are minted?
Market cap changes constantly because it is directly tied to the token's price, which fluctuates with supply and demand on exchanges. Even with a fixed circulating supply, a 10% rise in price produces a 10% rise in market cap. This makes market cap a real-time measure of collective investor sentiment. It is recalculated continuously throughout the trading day as prices update on exchanges worldwide.
How do I use market cap to decide which cryptocurrency to invest in?
Market cap helps you assess risk and growth potential relative to an asset's size. Large-cap coins (typically above $10 billion) tend to be more stable and liquid, making them suitable for conservative crypto exposure. Mid-cap and small-cap coins carry higher risk but may offer larger upside if adoption grows. You should combine market cap analysis with other factors like tokenomics, developer activity, and trading volume before making any investment decision.
