How to use Market Cap & FDV Calculator
Enter price and circulating supply for market cap; add fully diluted / max supply for FDV. Compare the gap when unlocks remain.
Example: Bitcoin market cap and FDV
Bitcoin trades at $65,000 with 19,700,000 coins in circulation and a 21,000,000 maximum supply.
- Market cap = $65,000 × 19,700,000 = $1,280,500,000,000
- Fully diluted valuation = $65,000 × 21,000,000 = $1,365,000,000,000
- Circulating share = 19,700,000 ÷ 21,000,000 = 93.81%
Market cap counts only coins that exist today ($1,280,500,000,000). FDV assumes the full supply is out ($1,365,000,000,000). The bigger the gap, the more future supply can dilute holders.
Formula & methodology
marketCap = price × circulating. FDV = price × fullyDilutedSupply (when provided).
Read market cap and FDV without the hype
Price alone hides float. Market cap and FDV make supply assumptions explicit so unlock overhang is visible next to the chart.
FDV is not destiny — it assumes today’s price on future supply. Use dilution and vesting tools when cliffs approach.
Remember liquidity: large caps can still slip on thin pairs.
