Market Cap Calculator — Crypto Market Capitalization Explained
Calculate cryptocurrency market cap, fully diluted valuation, and target prices from desired market cap. Compare valuations across different supply scenarios.
Market cap is the most commonly cited valuation metric in crypto, but it's also one of the most misunderstood — especially when people confuse circulating supply market cap with fully diluted valuation. The CalcHub Market Cap Calculator calculates both and helps you work backward from a desired market cap to find a price target.
The Formulas
Market Cap = Current Price × Circulating Supply Fully Diluted Valuation (FDV) = Current Price × Total Maximum SupplyThe difference between these two numbers matters enormously. A token with only 10% of supply in circulation and a high current market cap has an FDV that's 10× higher — meaning the remaining 90% of tokens, when they unlock, will exert significant price pressure unless demand grows proportionally.
Market Cap Interpretation
| Market Cap (USD) | Classification | Examples |
|---|---|---|
| > $100B | Mega cap | Bitcoin, Ethereum |
| $10B – $100B | Large cap | BNB, SOL, ADA |
| $1B – $10B | Mid cap | Many top-50 tokens |
| $100M – $1B | Small cap | Emerging DeFi protocols |
| $10M – $100M | Micro cap | New or niche projects |
| < $10M | Nano cap | Very high risk, high volatility |
How to Use the Calculator
- Calculate market cap: enter current price + circulating supply
- Calculate FDV: enter current price + total max supply
- Find price target: enter desired market cap + circulating supply to find implied price
- Compare scenarios: enter multiple market cap scenarios to see required price at each level
The Price Target Use Case
You're evaluating a DeFi token. Current price: $0.05. Circulating supply: 500M. Total supply: 5B.
Current market cap: $0.05 × 500M = $25M Current FDV: $0.05 × 5B = $250MIf you believe this protocol could reach $1B market cap (circulating), what's the price?
Target price = $1B / 500M = $2.00 per token (+3,900%)But if the full 5B supply circulates by then:
Price at $1B FDV = $1B / 5B = $0.20 per token (+300%)
Which is realistic depends entirely on the vesting schedule and when supply unlocks.
Market Cap vs Price: A Common Confusion
Many new investors focus on token price ("this coin is only $0.001, it must have room to 100×!") without considering supply. A $0.001 token with 100 trillion supply has a $100 billion market cap — larger than most blue-chip cryptos. Conversely, a $500 token with 1 million supply has a $500M market cap — a mid-cap project.
Price alone means nothing without supply context.The FDV Warning
Tokens with very low float (circulating %) and high FDV relative to market cap are a known risk pattern:
| Float % | FDV-to-MCap Ratio | Risk Signal |
|---|---|---|
| 80–100% | ~1x | Most supply is out; limited future dilution |
| 40–80% | 1.25–2.5x | Moderate future supply increase |
| 10–40% | 2.5–10x | Significant upcoming dilution |
| < 10% | > 10x | Very high dilution risk as supply unlocks |
Is market cap or FDV better for comparing crypto projects?
For comparing current valuations, use circulating market cap — it reflects what the market is actually pricing today. For assessing future dilution risk, FDV is essential. When comparing a protocol to a competitor, check both: a project with lower market cap but much higher FDV than competitors may be overvalued on a dilution-adjusted basis.
Why do stablecoins always show near-identical market cap and FDV?
Stablecoins like USDC, USDT, or DAI are minted and burned based on demand — there's no fixed total supply. The "total supply" for a stablecoin is effectively unlimited (bounded by demand), so FDV is not a meaningful metric. Only circulating supply market cap matters for stablecoins.
How is crypto market cap different from stock market cap?
Stock market cap = share price × shares outstanding, and shares outstanding is a legally precise number. Crypto circulating supply is more ambiguous — different data providers use different methodologies for whether to include locked, burned, or foundation-held tokens in "circulating" supply. Always verify supply figures from multiple sources (CoinGecko, CoinMarketCap, and the project's own documentation) before making valuation comparisons.
