Crypto Market Cap Calculator
“If DOGE had Bitcoin's market cap…” Settle it with numbers. Pick any two coins to see what one would cost with the other's market cap and how many multiples away that is, or work out market cap from price and supply. Live prices, editable everything, no sign-up.
≈ snapshot, 2026-07. Override any time.
≈ snapshot, 2026-07. Override any time.
Pick two coins (or fill in price and circulating supply manually) to see what the first would be worth with the second's market cap.
Market caps are estimated as live price × circulating supply from our 2026-07 snapshot. Supplies drift slowly for the majors, and every field above is editable. Paste exact numbers for exact results.
How to read the result
- Implied price: the second coin's market cap ÷ the first coin's circulating supply. What one coin would cost at that valuation.
- The multiple: how many times today's price would have to grow (or shrink) to get there. This is the number that separates plausible from fantasy.
- Estimated market caps: live price × snapshot supply for both coins, so you can see the gap you're bridging.
A coin needing a 3× to match a rival is a market-cycle story; a coin needing a 900× is a lottery ticket. Neither is a prediction, but if you have a view on the direction, put it on record and let your accuracy speak.
How to calculate a crypto market cap
A cryptocurrency market cap calculator does one core thing: multiply price by circulating supply. That is the whole formula.
- Market cap = price × circulating supply. The circulating supply is the number of coins actually in hands and tradable, not the maximum that could ever exist.
- Implied price = target market cap ÷ circulating supply. This is the “what if” side: give a coin another coin's valuation and see what one unit would cost.
Worked example, calculating a market cap from price and supply. Take a coin at $0.16 with 148 billion coins in circulation (the figures are illustrative, edit them above for live numbers):
0.16 × 148,000,000,000 = $23.68 billion.
Worked example, the “what if” direction. Suppose you want that same coin to reach Bitcoin's market cap, and you assume Bitcoin sits at $2 trillion. Divide the target cap by the coin's circulating supply:
2,000,000,000,000 ÷ 148,000,000,000 = $13.51 per coin (rounded). From $0.16 that is roughly an 84× move, because $2 trillion ÷ $23.68 billion ≈ 84. The two routes agree, which is a useful sanity check: the price multiple always equals the market cap multiple.
| What you want | Calculation |
|---|---|
| Market cap of a coin | price × circulating supply |
| Price at a target market cap | target market cap ÷ circulating supply |
| Multiple to get there | target market cap ÷ current market cap |
| Circulating supply, if you know cap and price | market cap ÷ price |
What would X be worth with Y's market cap?
This is the question the calculator exists to answer, so here are six popular pairings worked out at a fixed snapshot you can check by hand. The prices are rounded to keep the arithmetic clean; they were taken on 5 August 2026 and they will drift. Market caps used: Bitcoin's $1.28 trillion ($64,000 × 20 million BTC), Ethereum's $225 billion ($1,875 × 120 million ETH), Solana's $43 billion ($74 × 581 million SOL), Dogecoin's $11.2 billion ($0.070 × 160 billion DOGE). Supplies used for the smaller coins: 63 billion XRP, 37 billion ADA, 420 trillion PEPE, 589 trillion SHIB. Prices move, so run the live pair in the calculator above for a current answer.
| Scenario | Snapshot price | Implied price | Multiple |
|---|---|---|---|
| DOGE at Bitcoin's market cap | $0.070 | $8.00 | ~114× |
| XRP at Ethereum's market cap | $1.06 | $3.57 | ~3.4× |
| SOL at Ethereum's market cap | $74 | $387.26 | ~5.2× |
| ADA at Solana's market cap | $0.195 | $1.16 | ~6× |
| PEPE at Dogecoin's market cap | $0.0000029 | $0.0000267 | ~9.2× |
| SHIB at Dogecoin's market cap | $0.0000049 | $0.0000190 | ~3.9× |
Every row is the same division: target market cap ÷ circulating supply. XRP at Ethereum's cap is 225,000,000,000 ÷ 63,000,000,000 = $3.57; SOL at the same cap is 225,000,000,000 ÷ 581,000,000 = $387.26. The multiple is just implied price ÷ snapshot price, and it always equals the market cap multiple.
Don't let the implied prices impress you: supply does all the work. SOL at Ethereum's cap sounds dramatic at $387 but is only a 5.2× move, while PEPE crawling to Dogecoin's cap barely shifts the sticker price, $0.0000029 to $0.0000267, because 420 trillion tokens keep each one nearly worthless at any plausible valuation. The multiple column is the honest one. All of these numbers drift daily, so treat the table as a worked example and run the live pair in the calculator above.
Market cap calculator, marketcap calculator, market cap simulator: same job
People search for this tool under a handful of names. A cryptocurrency market cap calculator, a marketcap calculator, a crypto market cap calculator and a market cap simulator all point at the same two operations: work out a coin's valuation from price and supply, or run the reverse and solve for the price a coin would need at some target valuation.
The “simulator” framing just describes the second mode. You are simulating one coin sitting at another coin's market cap: hold the smaller coin's circulating supply fixed, borrow the larger coin's market cap, and read off the implied price. Nothing about the coin's actual supply, price or fundamentals changes; you are only asking a “what would it take” question and letting the arithmetic answer it.
That is also why a low unit price tells you almost nothing on its own. A fraction-of-a-cent coin with trillions of tokens can carry a larger market cap than a double-digit coin with a tiny supply. Comparing in market caps, not sticker prices, is the point of the whole exercise. If simulating the number gives you a view on where a coin is heading, log the call and let your accuracy, not your hunch, keep score. BitPredict is a free up or down prediction game: no money is staked and nothing here is financial advice.
Frequently asked questions
How is crypto market cap calculated?
Market cap = current price × circulating supply. If a coin trades at $2 and 10 billion coins are in circulation, its market cap is $20 billion. It's the standard way to compare the total size of two cryptocurrencies, because price alone says nothing without the supply behind it.
What does “X with the market cap of Y” mean?
It's a thought experiment: if coin X's total valuation grew to match coin Y's, what would one X cost? The calculator divides Y's market cap by X's circulating supply. It's useful for gut-checking hype: seeing that a small coin would need to 500× to reach Bitcoin's market cap tells you how realistic 'the next Bitcoin' claims are.
Why does a low coin price not mean a coin is cheap?
Because supply varies wildly. A $0.00002 coin with 500 trillion tokens in circulation is a bigger project by valuation than a $50 coin with 10 million tokens. Market cap normalizes for supply, which is exactly why this calculator works in market caps rather than raw prices.
Where does the circulating supply data come from?
Prices are live from BitPredict's price feed; circulating supplies come from a curated snapshot (currently 2026-07) covering the major assets. Supplies of large caps drift slowly, and both fields are editable. Paste the latest supply from any tracker for exact numbers.
Can a coin really reach another coin's market cap?
History says it's rare above the top ten. Overtaking a major requires tens or hundreds of billions of dollars of net new inflows, not just enthusiasm. The multiple this calculator shows is a good reality filter: 3–5× happens in bull markets; 500× almost never does at scale.
How do I calculate a crypto market cap?
Multiply the current price by the circulating supply. A coin at $0.16 with 148 billion coins circulating has a market cap of 0.16 × 148,000,000,000 = $23.68 billion. That single figure, not the price, is what lets you compare the size of two coins fairly.
What would Dogecoin be worth at Bitcoin's market cap?
Take Bitcoin's market cap and divide it by Dogecoin's circulating supply. Using a $1.28 trillion Bitcoin cap and 160 billion DOGE in circulation, the implied price is 1,280,000,000,000 ÷ 160,000,000,000 = $8.00 per DOGE. From a $0.070 snapshot price that is about a 114× move, which is the same as saying DOGE's market cap would have to grow 114 times to reach Bitcoin's. Swap in live numbers above for an exact figure.
What would XRP be worth with Ethereum's market cap?
Divide Ethereum's market cap by XRP's circulating supply. Using a $225 billion Ethereum cap and 63 billion XRP in circulation, the implied price is 225,000,000,000 ÷ 63,000,000,000 = $3.57 per XRP. From a $1.06 snapshot price that is about a 3.4× move. Both figures drift, so run the live pair in the calculator for a current answer.
What would Solana be worth with Ethereum's market cap?
Divide Ethereum's market cap by Solana's circulating supply. Using a $225 billion Ethereum cap and 581 million SOL in circulation, the implied price is 225,000,000,000 ÷ 581,000,000 = $387.26 per SOL. From a $74 snapshot price that is about a 5.2× move: a big-sounding price, but a market-cycle-sized multiple. Use the calculator above for live numbers.
