Crypto Market Cap & FDV Calculator
Use your own price and supply figures. Compare circulating market cap with an explicitly chosen supply basis, then test a hypothetical price scenario.
How it works & assumptions02 Read the assumptions with the result
Entered token price × entered circulating supply. Not the cash invested or available to sellers.
- Reference valuation
- Circulating share of reference supply
- Reference valuation / circulating cap
| Scenario market cap | |
|---|---|
| Scenario circulating supply | |
| Implied price at scenario supply | |
| Price at unchanged circulation | |
| Scenario price change vs entered price |
These are independent assumptions, not an expected return. Unlocks do not mechanically determine market demand or execution prices.
Inputs support up to 12 decimal places and 10¹⁵. Unsupported magnitudes are rejected. Displayed values and ratios may be rounded; very small non-zero results use scientific notation. Educational use, not financial advice.
Keep the supply assumption beside the valuation
The calculator multiplies a manual token price by a chosen supply, then lets you change market cap and circulation together. It does not fetch a token’s data or decide which supply figure is correct. The asset label is a label only; entering BTC will not populate Bitcoin’s price or supply.
Circulating market cap = Token price × Circulating supply
Reference valuation = Token price × Entered reference supply
Implied scenario price = Scenario market cap ÷ Scenario circulating supply
Scenario price change (%) = (Implied price ÷ Entered price − 1) × 100
Why the reference selector matters
In its supply methodology, CoinMarketCap distinguishes a maximum-supply FDV from a total-supply valuation. CoinGecko’s FDV explainer describes the calculation using total supply. Check the specific metric rather than assuming every source means the same thing.
Here, choosing maximum supply labels the answer “FDV — entered maximum supply.” Choosing total supply labels it “Valuation — entered total supply.” If neither figure is appropriate or known, select no reference supply. Missing data is shown as not supplied, not zero. Positive circulation is required; this is not a pre-launch valuation tool.
Worked example: market cap rises, token price falls
Take a fictional token priced at 2 USD with 100 million units circulating and a stated maximum of 500 million. Its circulating market cap is 200 million USD. Its maximum-supply FDV at the same price is 1 billion USD. Circulation is 20% of that maximum, and the reference valuation is five times the circulating valuation.
Now enter a hypothetical market cap of 300 million USD and circulation of 200 million. The implied price becomes 1.50 USD, 25% below the original 2 USD. Keeping the old 100 million circulation would instead imply 3 USD. Neither number is a prediction: they answer two different supply assumptions.
Use consistent inputs
- Use the same token, denomination and quote currency throughout. A redenomination can change both price and unit counts.
- Compare figures with compatible timestamps and definitions. Do not combine an old supply snapshot with a price and call the result a verified current market cap.
- Reference supply cannot be below circulation. A maximum-supply scenario also cannot exceed the entered maximum.
- Future circulation may exceed today’s total supply if new units are minted. Selecting total supply therefore does not apply a maximum-supply ceiling.
Read the market cap, FDV and token-unlock guide before interpreting dilution. Market cap is not cash invested, a treasury balance or the amount all holders can withdraw. This worksheet does not model demand, order-book depth, unlock selling or the probability of a target valuation.
