What Is Market Cap and How To Calculate It
Market cap is price times circulating supply. How to calculate it, how it differs from FDV, and why a low market cap never means a token is cheap.
Market cap is the price of one token multiplied by the number of tokens actually in circulation. It is the quickest way to compare two tokens whose prices look nothing alike, and the easiest number to be misled by.
- Market cap equals price times circulating supply. A token at 0.0001 USD with 10 billion in circulation is worth the same as one at 1 USD with 1 million.
- Price alone tells you nothing. A cheaper token is not a smaller one, and a token under a cent can still be the larger of the two.
- Fully diluted valuation uses total supply instead of circulating supply, so it is always the higher figure and often the more honest one.
- On Solana the circulating figure is the part that goes wrong most often, because locked, burned and team-held tokens are counted differently by different sites.
What is market cap?
Market cap is what the market currently says an entire token supply is worth. You get it by multiplying one token's price by how many tokens are in circulation, and it exists so that two tokens with very different prices can be compared on the same scale.
The comparison is the whole point. A token trading at 0.000004 USD sounds cheap and a token at 40 USD sounds expensive, but those two numbers say nothing about size until you know how many of each exist. Price is a per-unit figure. Market cap is the total.
How do you calculate market cap?
Multiply the current price by the circulating supply. That is the entire formula, and the difficulty is never the arithmetic. It is deciding which supply number belongs in it.
| Token | Price | Circulating supply | Market cap |
|---|---|---|---|
| Token A | 0.0001 USD | 10,000,000,000 | 1,000,000 USD |
| Token B | 1.00 USD | 1,000,000 | 1,000,000 USD |
| Token C | 0.50 USD | 900,000,000 | 450,000,000 USD |
Token A and Token B are the same size. One of them looks four zeroes cheaper, and a chart of price alone would never tell you they are worth exactly as much as each other.
What is the difference between market cap and FDV?
Fully diluted valuation multiplies price by total supply rather than circulating supply. It answers a different question: what would this be worth if every token that will ever exist were already trading.
The gap between the two matters most on young tokens. If a project circulates 10 percent of its supply and locks the rest for the team, the cap looks small and FDV looks large. Those locked tokens do unlock eventually, and when they do, the price has to absorb them.
- Market cap uses circulating supply and describes today.
- FDV uses total supply and describes the ceiling.
- A wide gap between the two is not automatically bad, but it is always worth knowing before you buy.
Why does a low market cap not mean cheap?
A low cap means the market has priced this token as small, and small has two very different explanations. It might be early. It might also be that nobody wants it.
The number carries no judgment. It reports what the last trades agreed on, multiplied by a supply figure that somebody chose how to count. Neither half of that is a valuation, and neither half is a promise.
A market cap can be manufactured. Mint a billion tokens, sell a handful at a high price to a wallet you control, and every tracker will report a large number. Thin liquidity is what gives it away.
How do you check a Solana token's market cap?
Start from supply, not from the headline figure. Any tracker can show a figure; the useful question is whether the supply behind it is real, and that is answerable on chain in about a minute.
Pull the holder list and the supply with the token snapshot tool and check three things: how much of the supply sits in the top few wallets, whether any of it has been burned, and whether the rest is genuinely liquid. A supply that is 80 percent held by four addresses is not really circulating, whatever the tracker says.
Then look at how those wallets relate to each other. the Wallet Scope wallet map maps the transfers between holder wallets, which is how a cluster funded from one source stops looking like a crowd. If the supply was reduced deliberately, burning tokens is the operation that did it, and burned supply should be out of the circulating figure.
What market cap does not tell you
The cap is one number and it answers one question. Three things it never covers, and all three have cost people money.
- Liquidity. A 50 million USD cap with 20,000 USD in the pool cannot be sold into. Cap measures notional size, not exit capacity.
- Who holds it. Two tokens can share a cap while one has 40,000 holders and the other has nine.
- Whether the supply figure is honest. Circulating supply is reported, not enforced, and different sites reach different answers for the same token.
Read it as a size label and nothing more. Comparing two tokens by cap is fair. Concluding one is undervalued because its cap is lower is not, and that leap is the reason the number gets quoted so often.

Frequently asked questions
What is a good market cap for a crypto token?
There is no good number. Cap describes size, not quality, and a large one only means more money is already committed. Compare a token's cap against its liquidity and holder count instead; those two say more about whether the size is real.
How is market cap different from trading volume?
Cap is a stock and volume is a flow. It is what the whole supply is worth right now, while volume is how much changed hands over a period. A token can carry a large cap on almost no volume, and that combination is worth a second look.
Can the cap go up while the price stays flat?
Yes, if circulating supply increases. New tokens unlocking or being minted raise it at an unchanged price. The reverse also holds: burning supply lowers the cap without the price moving at all.
Why do two sites show different caps for the same token?
Because they disagree about circulating supply. One may exclude team allocations and locked tokens while another counts everything that is not burned. The price is the same on both; the supply assumption is what differs.
Does burning tokens increase the price?
Not by itself. Burning reduces supply, which lowers the cap at an unchanged price. Price only moves if demand stays while supply shrinks, and a burn announces nothing about demand.
Where does the circulating supply number come from?
From whoever publishes it. On Solana the total supply is on chain and verifiable, but the split between circulating, locked and team-held is a reporting decision. That is why checking the holder list beats trusting the label.
