Market Cap Comparison Calculator
See what any crypto or stock would be worth with another asset's market cap. Market cap comparison for Bitcoin, Ethereum, Apple, and more.
The market cap comparison calculator answers the question "what would X be worth if it had the market cap of Y?" It derives the circulating supply from your asset's current price and market cap, then applies the target asset's market capitalisation to produce a hypothetical price, a multiple, and a percentage change. The tool runs entirely in your browser and works for any cryptocurrency, stock, ETF, or commodity.

About Market Cap Comparison Calculator
How the Calculation Works
The maths reduces to two divisions: supply equals market cap divided by price, and the hypothetical price equals the target market cap divided by that supply. Nothing more complicated is happening under the hood.
| Step | Formula | Example (Ethereum at Bitcoin's market cap) |
|---|---|---|
| 1. Calculate supply | Supply = Market Cap / Price | 120.5M ETH = $200B / $1,660 |
| 2. Calculate hypothetical price | New Price = Target Market Cap / Supply | $13,571 = $1.60T / 117.9M |
| 3. Calculate multiple | Multiple = New Price / Current Price | 6.4x = $10,540 / $1,660 |
| 4. Calculate % change | Change = (Multiple - 1) x 100 | +493% |
Worked example (June 2026 figures): Ethereum trades at roughly $1,660 with a $200B market cap, implying a circulating supply of about 120.5 million ETH. Bitcoin's market cap sits near $1.27 trillion (CoinMarketCap, mid-June 2026). Applying that target to Ethereum's supply gives $10,540 per ETH - roughly 6.4x the current price. That is what it would take for ETH to match BTC's current total value at today's supply.
Why Market Cap Matters More Than Price
Per-unit price tells you almost nothing about an asset's size. A $1 token with 100 billion units in circulation has a $100 billion market cap, which is larger than most S&P 500 companies. A $500 stock with only 10 million shares outstanding is a $5 billion company - small cap territory. Market cap = Price x Circulating Supply is the only fair comparison between assets.
| Common Misconception | Reality |
|---|---|
| "This $0.01 token could reach $1,000 like Bitcoin" | If it has 100 billion tokens, reaching $1,000 would mean a $100 trillion market cap - more than all US stocks combined |
| "Stock A at $5 is cheaper than Stock B at $500" | Stock A might have 10 billion shares outstanding ($50B market cap) while Stock B has 10 million shares ($5B market cap) |
| "This coin has a low price, so there's more room to grow" | Growth potential depends on market cap relative to fundamentals, not on the per-unit price |
| "Market cap equals money invested" | Market cap is last-traded price multiplied by supply. Selling a tiny fraction of supply can move the price and wipe billions off the cap without any money actually leaving |

What Are the Standard Market Cap Tiers?
The tier bands below are the conventions used by most US brokers and index providers (FTSE Russell, S&P). Crypto has no official tiering, but traders typically borrow the same bands. Use them to understand what class of asset you are comparing against.
| Tier | Market Cap Range | Characteristics |
|---|---|---|
| Mega cap | $200B+ | Household names (Nvidia, Apple, Microsoft, Bitcoin), high liquidity, lower volatility |
| Large cap | $10B - $200B | Established companies, institutional investment, moderate volatility |
| Mid cap | $2B - $10B | Growing companies, higher growth potential and risk |
| Small cap | $300M - $2B | Emerging companies, high volatility, less liquidity |
| Micro cap | $50M - $300M | Speculative, very high volatility, thin trading |
| Nano cap | Under $50M | Highest risk, potential for manipulation, minimal liquidity |
Circulating vs Fully Diluted Valuation
Circulating supply only counts units that are currently tradable. Fully diluted valuation (FDV) assumes every token ever planned is already in circulation, including team vesting, foundation treasuries, and future emissions. The gap between the two can be enormous. Several L1 and L2 tokens have FDVs 3-5x their circulating market cap, meaning the "real" cost to reach a target price is much higher than the back-of-envelope supply calculation suggests.
For stocks the equivalent concept is basic shares versus fully diluted shares (including employee options, convertible debt, and warrants). Large tech companies typically have a diluted share count 2-4% above basic, which is a much smaller adjustment than crypto FDV. This tool uses circulating supply only - apply an FDV haircut yourself if you want a conservative estimate for assets with heavy future emissions.
Common Mistakes When Using Market Cap Comparisons
The most common mistake is treating the output as a price target rather than a sizing exercise. Reaching Bitcoin's market cap requires the same net demand that Bitcoin itself attracted over 15 years. The calculator tells you the price if that demand materialised at today's supply, not the probability of it happening.
| Mistake | What to Do Instead |
|---|---|
| Using fully diluted cap on one side and circulating on the other | Keep the basis consistent. If comparing two crypto assets, use circulating for both or FDV for both |
| Comparing a commodity cap (gold) to an equity cap | Equity caps represent a claim on future earnings; commodity caps are just units times spot price. They are not the same type of claim |
| Ignoring inflation of token supply | High-inflation tokens (7%+ annual emission) dilute existing holders even if price stays flat |
| Assuming all supply is liquid | Much of Bitcoin's supply is held long term; only a fraction trades on any given day. Real-world liquidity is well below circulating supply |
Historic Market Cap Milestones
Market caps at the top of the ranking shift faster than most people realise. Apple was the first US company to reach a $1 trillion market cap in August 2018, $2 trillion in August 2020, and $3 trillion in January 2022. Nvidia hit $1 trillion in May 2023, $2 trillion in February 2024, $3 trillion in June 2024, and $4 trillion in mid-2025 - the fastest ever. Bitcoin first touched $1 trillion in February 2021, lost it during the 2022 bear market, and reclaimed it in December 2023. These milestones are a useful sanity check when someone pitches a sub-$1B token "heading to $1 trillion" - the real-world precedent shows how much time and capital inflow that scale of growth requires.
| Asset | $1T Milestone | $2T Milestone | $3T Milestone |
|---|---|---|---|
| Apple | Aug 2018 | Aug 2020 | Jan 2022 |
| Microsoft | Apr 2019 | Jun 2021 | Jan 2024 |
| Nvidia | May 2023 | Feb 2024 | Jun 2024 |
| Alphabet | Jan 2020 | Nov 2021 | Apr 2024 |
| Bitcoin | Feb 2021 | Nov 2024 | Not reached |
Crypto vs Stock Market Cap: Key Differences
The formula is identical but the meaning is not. A stock's market cap is a claim on the company's future earnings, book value, and productive assets. A buyer at today's price is implicitly paying for all future dividends and buybacks. Cryptocurrency market cap is purely price times supply - there are no earnings to discount. That is why crypto caps swing 50-80% intra-year while blue-chip equity caps rarely move more than 30% outside a recession. Use the comparison carefully: a $1 trillion crypto market cap and a $1 trillion equity market cap represent very different economic claims.
Another difference: stocks have a fixed outstanding share count that changes only via buybacks, issuances, or stock splits. Crypto supply can change daily through minting, burning, and vesting cliffs. Ethereum's supply has been roughly flat since the September 2022 merge because burns from EIP-1559 offset new issuance, but Solana's supply grows about 5% per year. When running a multi-year scenario, factor in supply growth - the hypothetical price at a given market cap drops as supply rises.
How to Find Accurate Inputs
Garbage in, garbage out. The quality of the hypothetical price depends entirely on the accuracy of the price and market cap you feed in. For cryptocurrencies, CoinGecko and CoinMarketCap both publish circulating supply alongside price, and their figures usually agree within 1-2%. For US stocks, Yahoo Finance and Google Finance pull market cap directly from the exchanges. For international stocks, the company's own investor relations page or the local exchange site is the safest source. For commodities, the World Gold Council publishes quarterly above-ground totals, and the Silver Institute does the same for silver.
One subtle trap: some data providers report "fully diluted market cap" as the default (especially for newer tokens), while the calculator assumes you are entering the circulating cap. If you pull a figure from a DEX aggregator or a token launch page, double-check whether it is circulating or FDV before using it here.

Frequently Asked Questions
How does the market cap converter work?
It divides the target market cap by the supply of your asset (calculated from its current price and market cap) to determine what the price would be. The formula is simple - hypothetical price equals target market cap divided by circulating supply.
Why can't a small crypto just reach Bitcoin's market cap?
Market cap reflects total value, not just price. A token with 100 billion supply would need massive capital inflows to match Bitcoin's market cap. This tool helps visualise how realistic that would be by showing the implied price.
Where do I find market cap data?
Check CoinGecko or CoinMarketCap for crypto, and Yahoo Finance or Google Finance for stocks. The tool includes preset values for popular assets but you can enter your own.
Does this account for future token emissions or dilution?
No, it uses the current circulating supply implied by the price and market cap you enter. Future token unlocks, stock splits, or share buybacks would change the supply and therefore the hypothetical price.
Can I use this for any asset?
Yes. It works for any asset with a price and market cap, including cryptocurrencies, stocks, ETFs, commodities, or even entire markets. Just enter the numbers.
