Market Cap and Fully Diluted Valuation (FDV) measure two different sides of a cryptocurrency’s valuation. Market Cap values the tokens currently circulating, while FDV applies the current token price to a broader supply.
The difference between the two can reveal how much potential token supply remains outside circulation.
For example, a cryptocurrency might have a $100 million Market Cap but a $1 billion FDV. That does not automatically mean it is overvalued, but it does tell you that its current circulating valuation represents only a fraction of its fully diluted valuation.
This gap becomes particularly important for low-float tokens, where significant amounts of supply may enter circulation through future token unlocks.
Market Cap vs FDV: What Is the Difference?
The main difference is the supply used in each calculation.
| Metric | Typical calculation | What it shows |
|---|---|---|
| Market Cap | Price × Circulating Supply | Value of the currently circulating supply |
| FDV | Price × Fully Diluted Supply | Theoretical valuation using a broader supply |
| Market Cap / FDV | Market Cap ÷ FDV | Size of the gap between the two valuations |
Consider a cryptocurrency trading at $1 with 100 million tokens circulating and a fully diluted supply of 1 billion tokens.
Its Market Cap is:
$1 × 100 million = $100 million
Its FDV is:
$1 × 1 billion = $1 billion
The cryptocurrency therefore has a Market Cap equal to only 10% of its FDV.
Why Can a Low Market Cap Hide a High Fully Diluted Valuation?
A low Market Cap does not necessarily mean a cryptocurrency has a low overall valuation.
Imagine a fictional cryptocurrency called Nova:
- Token price: $1
- Circulating supply: 50 million
- Fully diluted supply: 1 billion
Its Market Cap is only $50 million:
$1 × 50 million = $50 million
But its FDV is $1 billion:
$1 × 1 billion = $1 billion
Only 5% of the fully diluted supply is currently circulating.
This is sometimes described as a low-float, high-FDV structure. The cryptocurrency looks relatively small when viewed only through Market Cap, but its broader supply implies a much larger valuation at the same token price.
Mature Supply vs Low Float: A Simple Comparison
Two cryptocurrencies with the same price and FDV can have very different supply structures.
| Metric | Atlas | Nova |
|---|---|---|
| Token price | $1 | $1 |
| Circulating supply | 950 million | 50 million |
| Fully diluted supply | 1 billion | 1 billion |
| Market Cap | $950 million | $50 million |
| FDV | $1 billion | $1 billion |
| Market Cap / FDV | 95% | 5% |
Atlas already has most of its supply circulating. Nova has only a small fraction circulating.
Looking only at Market Cap makes Nova appear much smaller. Looking at FDV reveals that both cryptocurrencies have the same theoretical fully diluted valuation at their current $1 price.
This does not mean Nova’s price must fall. It means there is substantially more potential supply outside circulation.
How Does the Market Cap/FDV Ratio Work?
The Market Cap/FDV ratio provides a simple way to measure the gap between the two valuations:
Market Cap / FDV = Market Capitalization ÷ Fully Diluted Valuation
For example:
- $900 million Market Cap ÷ $1 billion FDV = 90%
- $500 million Market Cap ÷ $1 billion FDV = 50%
- $50 million Market Cap ÷ $1 billion FDV = 5%
When the same price and compatible supply definitions are used, the ratio largely reflects how much of the relevant token supply is already circulating.
A ratio close to 100% means the gap between Market Cap and FDV is relatively small. A low ratio indicates that a much larger proportion of supply remains outside the circulating valuation.
However, the ratio should be used as a screening metric rather than a quality score. A 10% ratio does not automatically mean a cryptocurrency is overvalued or that its price will fall.
What Is a Good Market Cap/FDV Ratio?
There is no universal Market Cap/FDV ratio that makes a cryptocurrency good or bad.
A higher ratio generally indicates that more of the relevant token supply is already circulating, which means less potential dilution from that remaining supply.
A lower ratio indicates a larger gap and gives you a reason to investigate how future tokens will enter circulation.
For example, two cryptocurrencies could both have a 10% Market Cap/FDV ratio while having very different token schedules. One might release its remaining supply gradually over ten years, while another could have large investor and team unlocks during the next 12 months.
The ratio alone cannot capture that difference.
Why Do Token Unlocks Matter?
A token unlock occurs when previously restricted tokens become transferable according to a project’s vesting or distribution schedule.
These tokens may be allocated to:
- Founders and team members
- Early investors
- Project treasuries
- Foundations
- Ecosystem incentives
- Community rewards
As these tokens become available, circulating supply can increase.
If new supply enters the market faster than demand grows, it can create selling pressure. However, token unlocks do not automatically cause prices to fall. Recipients may hold rather than sell, and growing demand can absorb additional supply.
This is why the unlock schedule can be more informative than the headline FDV alone.
Is a High FDV Bad?
No. A high FDV is not automatically negative.
FDV needs to be interpreted alongside Market Cap and the project’s token distribution.
For example, a cryptocurrency with a $5 billion FDV and 90% of its supply circulating has a very different supply profile from another $5 billion FDV cryptocurrency with only 5% circulating.
The second project potentially has much more future dilution, but even that does not determine what its price will do.
When the gap between Market Cap and FDV is large, investigate:
- How much supply is currently circulating?
- When are the next major token unlocks?
- How quickly will circulating supply increase?
- Who receives the newly unlocked tokens?
- Are unlocks gradual or concentrated?
- Does the project have ongoing emissions or token burns?
Why FDV Does Not Mean Money Invested
Neither Market Cap nor FDV measures how much cash investors have actually put into a cryptocurrency.
Both are valuation calculations based on token price and supply.
For example, if a token’s market price rises from $1 to $2, its calculated Market Cap and FDV can double even though an equivalent amount of new money has not entered the cryptocurrency.
This distinction becomes especially important for low-float tokens. A relatively small circulating supply can trade at a high price, and applying that price to a much larger fully diluted supply can produce a very large FDV.
FDV should therefore be understood as a theoretical valuation, not as an amount of capital invested.
Why a Cheap Token Can Still Have a High FDV
Token price alone tells you very little about whether a cryptocurrency is cheap or expensive.
Imagine a cryptocurrency priced at just $0.05 with a fully diluted supply of 100 billion tokens.
Its FDV would be:
$0.05 × 100 billion = $5 billion
The token costs only five cents, but its fully diluted valuation is already $5 billion.
If the same token reached $1 with the same supply basis, its FDV would become $100 billion.
This is why price targets should always be considered alongside token supply and the resulting valuation.
What If a Cryptocurrency Has No Maximum Supply?
FDV becomes less straightforward when a cryptocurrency does not have a fixed maximum supply.
Some cryptocurrencies have a hard-coded supply ceiling. Others use ongoing issuance, token burns or dynamic monetary policies.
In these cases, market-data providers may use different supply measures when displaying FDV.
This means FDV figures from different platforms may occasionally differ. When comparing cryptocurrencies, check which supply figure is being used rather than assuming every FDV is calculated in exactly the same way.
How to Analyze a Low-Float, High-FDV Cryptocurrency
If a cryptocurrency has a large gap between Market Cap and FDV, the ratio should be the beginning of your research rather than the conclusion.
Start by checking:
- Circulating supply: What percentage of the relevant supply is already circulating?
- Token unlocks: When will significant new supply become transferable?
- Vesting schedule: Will tokens be released gradually or through large unlocks?
- Token allocation: Who controls the non-circulating tokens?
- Issuance: Are staking rewards, mining or other emissions increasing supply?
- Burns: Are tokens also being permanently removed from supply?
A low Market Cap/FDV ratio accompanied by gradual issuance over many years can have very different implications from the same ratio combined with large near-term investor unlocks.
Frequently Asked Questions
What is the difference between Market Cap and FDV?
Market Cap uses circulating supply, while FDV applies the current token price to a broader supply measure. Market Cap therefore represents the valuation of currently circulating tokens, while FDV provides a theoretical broader valuation.
What does a low Market Cap/FDV ratio mean?
A low ratio indicates a large gap between circulating Market Cap and fully diluted valuation. It suggests that a significant amount of supply may remain outside circulation and is a reason to investigate future token issuance and unlocks.
What is a good Market Cap/FDV ratio?
There is no universal ratio that makes a cryptocurrency good or bad. A higher ratio generally means more of the relevant supply is already circulating, while a lower ratio indicates a larger supply gap.
Is a high FDV bad?
Not necessarily. FDV should be considered alongside circulating supply, token unlocks, vesting schedules and the rate at which additional tokens may enter circulation.
Do token unlocks always make crypto prices fall?
No. Token unlocks can increase available supply, but their effect depends on demand, liquidity, market expectations and whether recipients decide to sell.
Why can Market Cap and FDV be almost identical?
The two figures become closer when circulating supply approaches the supply figure used to calculate FDV. This generally means that a relatively large proportion of the relevant token supply is already circulating.
Final Thoughts
Market Cap shows the valuation of a cryptocurrency’s circulating supply, while FDV shows the valuation implied by a broader supply at the current token price.
The gap between them can be particularly useful when analyzing low-float cryptocurrencies. A low Market Cap combined with a much higher FDV can indicate that significant additional supply may enter circulation in the future.
The Market Cap/FDV ratio provides a quick way to measure that gap, but it should not be treated as a verdict. Token unlocks, vesting schedules, allocations and issuance rates provide the context needed to understand what the difference actually means.
