Market Cap vs FDV: How to Read a Token's Real Valuation
Two coins can show the same price but be valued very differently. Understanding market cap versus fully diluted valuation helps you see how much supply is still waiting to hit the market.
What market cap and FDV actually measure
When you look up a crypto token, you will usually see two numbers that sound similar but mean very different things: market cap and fully diluted valuation (FDV). Both try to express how much a project is "worth," but they count supply differently.
- Market cap = current price × circulating supply (the tokens actually available and trading right now).
- FDV = current price × maximum supply (every token that will ever exist, including those still locked, vested, or unmined).
In other words, market cap reflects today's reality, while FDV is a hypothetical: what the project would be worth if every token existed today at the current price. For a deeper look at each metric on its own, see our guides to crypto market cap and fully diluted valuation.
Why the gap between the two numbers matters
The ratio between market cap and FDV tells you how much of the supply is already "out there" versus still locked away. This portion is often called the float or circulating ratio.
| Metric | Project A | Project B |
|---|---|---|
| Price | $1 | $1 |
| Circulating supply | 90 million | 5 million |
| Max supply | 100 million | 1 billion |
| Market cap | $90 million | $5 million |
| FDV | $100 million | $1 billion |
| Circulating ratio | 90% | 0.5% |
Project A has almost all of its tokens in circulation, so its market cap and FDV are close. Project B has the same price but barely any of its supply unlocked. If the rest of Project B's tokens are released over time, that new supply has to be absorbed by the market, often through selling pressure unless demand grows just as fast.
Why high FDV with low float is a warning sign
A token with a low float and high FDV means a small number of tokens are setting the price, while a much larger amount is scheduled to unlock later. This setup deserves caution for a few reasons:
- Thin float inflates the price. When only a tiny fraction of supply trades, it takes less money to push the price up, which can make a project look more valuable than it is.
- Future unlocks add sell pressure. Early investors, team members, and funds often receive tokens on a vesting schedule. When those tokens unlock, holders may sell, increasing supply faster than demand can keep up.
- The FDV may be unrealistic. A $1 billion FDV implies the market will eventually value the whole supply at that level. That is a high bar, and the price often falls as more tokens enter circulation.
None of this means a high-FDV token is automatically a bad project. It means you should ask where the rest of the supply is and when it unlocks before assuming the current price is sustainable. Understanding a project's tokenomics and supply schedule is essential homework, and being able to spot unrealistic valuations is part of learning to avoid crypto scams.
How to check these numbers yourself
You do not need advanced tools to evaluate the float and unlock picture. A short checklist covers most of it:
- Compare market cap to FDV. If FDV is many times larger than market cap, a lot of supply is still locked.
- Find the circulating ratio. Divide circulating supply by max supply. A very low percentage means a thin float.
- Read the vesting schedule. Check the project's documentation for when team and investor tokens unlock. Large "cliffs" can mean sudden supply increases.
- Watch unlock calendars. Several public trackers show upcoming token unlocks so you can anticipate supply events.
- Confirm the max supply is fixed. Some tokens have no hard cap or can be minted indefinitely, which makes FDV harder to pin down. Compare this to assets like Bitcoin, which has a fixed maximum supply, versus more flexible models on Ethereum and many altcoins.
Putting it all together
Market cap tells you what a token is worth based on supply available today. FDV tells you what it would be worth if every token existed at the current price. The relationship between them, and the unlock schedule that closes the gap, is often more revealing than the price alone.
As a beginner, treat a wide market-cap-to-FDV gap as a prompt to dig deeper, not as a buy or sell signal on its own. A balanced view looks at the team, the product, real usage, and the supply timeline together. Pair this with sound habits like position sizing and a clear understanding of your own trading psychology.
