About the Crypto Market Cap Calculator
This crypto market cap calculator answers the classic “what if” question: if a coin reached a given market capitalisation, what would one coin be worth? Enter the current price, the circulating supply and a target market cap, and it returns the implied price, the multiple (2x, 10x, 100x) and the percentage move required to get there.
It is useful for sanity-checking price predictions. A token that needs to be worth more than the entire gold or stock market to hit someone’s target is a red flag, and the milestone table makes that obvious in seconds. Add the maximum or total supply to see the fully diluted valuation (FDV) — the market cap if every token that will ever exist were already circulating.
The math assumes the circulating supply stays the same. Real supplies change through emissions, unlocks, burns and staking rewards, so for tokens with heavy future unlocks the FDV figure is often the more honest comparison.
With the default inputs, the price at target market cap is $50.0000. Change any value above to recalculate instantly.
How to use the crypto market cap calculator
- 1Enter the coin’s current price and circulating supply.
- 2Optionally enter the max or total supply to see fully diluted valuation.
- 3Type the market cap you want to test, such as $10 billion or $1 trillion.
- 4Read the implied price, the multiple needed and the percentage move.
- 5Scan the milestone table to judge whether a price target is realistic.
Formula and method
Market capitalisation is simply price multiplied by circulating supply, so the price at any market cap is the market cap divided by the supply. The multiple compares that implied price with today’s price, and the percentage change is (multiple − 1) × 100.
Fully diluted valuation multiplies the current price by the maximum (or total) supply instead of the circulating supply. The calculator assumes the circulating supply does not change between now and the target — if many tokens unlock, the price at the same market cap will be lower than shown.
- MC
- Market cap = price × circulating supply
- S
- Circulating supply (coins in circulation)
- FDV
- Fully diluted valuation = price × max supply
Worked examples
$2.50 coin with 1 billion supply at a $50B market cap
Today the coin is worth $2.50 × 1,000,000,000 = $2.5 billion. At $50 billion each coin would be $50 ÷ 1 = $50, a 20x (+1,900%) move. With 2 billion max supply the FDV is $5 billion today, and a $50 billion fully diluted value would mean only $25 per coin.
Low-priced coin with a huge supply at $1 trillion
With 55 billion coins at $0.60 the market cap is $33 billion. A $1 trillion market cap works out to $1,000,000,000,000 ÷ 55,000,000,000 ≈ $18.18 per coin — about 30x from today, which shows how supply caps what a “cheap” coin can realistically reach.
Bitcoin-sized asset reaching $2 trillion
At $60,000 with 19.8 million coins circulating, market cap is $1.188 trillion. A $2 trillion valuation implies about $101,010 per coin, a 1.68x move. FDV using the 21 million cap is $1.26 trillion.
Frequently asked questions
How do you calculate a crypto coin’s market cap?+
Multiply the current price by the circulating supply. A coin priced at $2 with 500 million coins in circulation has a market cap of $1 billion.
What is the difference between market cap and FDV?+
Market cap uses the coins circulating today. Fully diluted valuation (FDV) uses the maximum or total supply, so it shows the valuation if every locked, vested or not-yet-mined token were already trading.
Can a low-priced coin easily reach $1?+
Not necessarily. Price depends on supply: a coin with 500 billion tokens needs a $500 billion market cap to reach $1, which is larger than most companies in the world. Always check the market cap a price target implies.
Does a bigger market cap mean more money was invested?+
No. Market cap is the last trade price times supply, not money invested. Thin order books mean a small amount of buying can move the price — and the market cap — far more than the cash that went in.
Why might the price at a target market cap be lower than shown?+
The calculator holds circulating supply constant. Token unlocks, mining or staking emissions increase supply over time, so the same market cap would be spread across more coins and each would be worth less.
