Cryptocurrency Market Cap Explained: How It Is Calculated
Cryptocurrency Market Cap Explained: How It Is Calculated
Gain a hands on understanding of what crypto market cap is and how it’s determined solely via price and circulating supply.
Quick Answer
Deriving a coin’s market cap can be done simply by multiplying a coin’s price and its circulating supply. The market cap of a coin does not signify the amount that has been poured into the coin, what it does is give the price those coins are worth at that price.
Major takeaways
To calculate a market cap is pretty easy once you are able to ascertain what you would call circulating supply.
What market cap ranking does is to tell you which coin is larger when compared to others, it does not imply that assets that appear above a certain token or below are performing better or worse.
To get a clearer picture of what is actually happening to a token, look at the price, supply, and trading volume together. Then do a diligent check as to whether more tokens are due to enter circulation.
What Cryptocurrency Market Cap Actually Measures
You might see a token costing a few cents next to one that costs a thousand dollars. The prices themselves are quite meaningless as a measure of which asset is really bigger; there could be billions of units of the cheap asset, versus only a fraction of that for the costly one.
Market capitalization (market cap, for short) price times supply. It tells you how much money all of the coins would be worth based on their current price. (Super useful for comparing coins with very different unit prices, since it's a total.)
It doesn't necessarily mean that the cash did hit the asset. Imagine the last price goes up, this method tries to assign the new price to every single unit of the asset that is in circulation, even though it may be that only a handful of those units are bought or sold. Not everyone may be willing to sell at that price, because a sale of such size might affect the market.
How Market Cap Is Calculated
The standard calculation is (Market cap = current price per unit × circulating supply)
To put this into perspective, let’s assume the price of a token is $2 and this token has a total number of 50 million tokens in circulation. As a result, the market cap is exactly $100 million. However, if the price of this token jumps to $3 due to massive demand, the market cap will also pump to $150 million. That $50 million increase does not imply buyers deposited another $50 million; it only means that the token’s new $3 price is now being applied to all 50 million tokens already in circulation.
But the price is not the only thing that can change the market cap of a coin/token. Developers or creators of a token sometimes decide to add more supply to a token and by this, the market cap can also be affected. For example, the market cap of the imaginary token we mentioned earlier can reduce if we add an additional 10 million tokens to the supply. Since the supply is now 60 million tokens, the market cap will dip to $120 million (50 + 10 million × $2).
As illustrated above, you would see that the market cap cannot be deemed static; it changes based on market operations and, of course, the actions of the creators of a token or coin.
Circulating vs Total vs Max Supply: Why the Number Moves
These three help you understand market cap:
| Supply Figure | What it means |
|---|---|
| Circulating supply | The number of tokens that are currently in circulation over a given period. |
| Total supply | The number of tokens that exist, including those that may still be locked or reserved (temporarily inaccessible until a fixed release date). |
| Max supply | The highest number of tokens that can ever exist throughout the lifetime of a coin or token. Bitcoin, for example, has a fixed coin supply of 21 million. |
Now, to give you a clear understanding of what the total and circulating supply mean, let’s say a certain project created a total of 100 million tokens but holds 40 million in locked allocation. This automatically translates to the fact that only 60 million tokens are in circulation, and despite having a total of 100 million tokens, only the circulating 60 million would be used to calculate the market cap. To directly affect the total supply, projects can also add more to the total supply or, in some cases, burn tokens massively as the BNB project does. Worthy of note is also the fact that the market cap displayed by different onchain data providers like CoinGecko and CoinMarketCap may differ. To track the market, these onchain sites rely on wallet balances, lockups, project disclosures, and their own private rules. So when you spot anything that might look like a stark difference in the market cap of a token published by these different providers, do well to review the rules of the contrasting onchain data providers. Check out CoinGecko’s supply methodology and CoinMarketCap’s supply definitions for examples of those rules.
Market Cap vs Fully Diluted Valuation (FDV)
To understand the distinction between these two, you need to first understand that they are linked to total supply. As for market cap, we define it as the total number of tokens in circulation multiplied by the price per token. With that in mind, Fully Diluted Valuation is simply the total value of the total tokens that have been created if all of these tokens were to be unlocked. If you’re active in crypto, you’d notice that most tokens usually have a market cap that is relatively lower than their FDV. This means that if the project were valued at the current price and all available tokens, the designated amount would be the FDV. In practice, a project can have a $10 million market cap and a $100m FDV, meaning that only 10% of the supply is in circulation, with the remaining 90% unlocked. For a closer look at the distinction, XXKK’s FDV versus market cap explainer offers more insight.
What Market Cap Rankings Do Not Tell You
Crypto market cap rankings, like stock market rankings, reflect nothing but the list of crypto assets that are valuable in descending order for users. It can be described as a list that shows the largest asset in the market at that time. The crypto market at the moment is led by Bitcoin, Ethereum, and other equally valuable assets.
But while an asset can be ranked high or low by market cap, it does not in any way reflect the holder distribution, the likelihood of success, the potential for a downtrend, code security, or the token's governance. This is important to know because even projects that rake up high market caps often experience downtrends in the market due to factors like team withdrawal or little hype around the project, and in some cases, the market cap can be fake, thereby leading to a rug pull. Also, considering that projects can easily even boost their market cap rankings by burning supply, the idea of gauging a project’s progress by its market cap reads even more shallow.
Using XXKK Market Data to Compare Assets
To make smart investment choices, it’s of utmost importance that you compare crypto assets’ market caps to one another and for this, you should use a source that displays market data the way it is. With XXKK, you get direct access to ultra-important metrics like circulating supply as well as total or max supply of all tokens. If peradventure you discover an asset that you believe looks promising but is unbelievably cheap, don’t hesitate to multiply the token price by the total supply so you can get the bigger picture. If a large percentage of the supply is yet to enter circulation, do well to run a quick check on the unlock schedule. XXKK’s 2026 market outlook sheds more light on things you should look out for.
Conclusion
The market cap of every token in crypto answers the very big question of just how valuable a token is and nothing more to a large extent. Other questions that a potential investor may have in mind (whether the project will do well or decline) are subject to a number of factors, with the market cap as an exception. When you want to DYOR, in-depth research on a token’s liquidity, volume, and planned token releases is very important. While market cap might sound important, looking into the other factors mentioned can really boost your ability to tell good tokens from bad ones.
FAQs
What is cryptocurrency market cap?
It is simply the current market value of a token when the current market price and the total number of tokens in circulation are multiplied.
How is market cap calculated?
The market cap of a token can be calculated it multiplying the price and circulating supply.
Why do different sites show different market caps?
Mostly because no one is in charge of the number. There are always tiny disagreements about what most onchain data providers count as circulating supply, team-held tokens, and locked tokens. Also, a stark difference in supply methodologies can cause differences.
Does a high market cap mean a coin is safe?
No. A higher ranking shows a larger calculated value under that provider’s method. It does not remove price, liquidity, technical, or project risks.
