Using the Ethereum Market Cap Calculator
Market cap is simply the live ETH price multiplied by the number of coins in circulation, and this page does that with the current price loaded for you. The supply field starts at roughly 120.7 million ETH, which is where it stood on 31 July 2026 — supply moves, so check it against a market data source if you need an exact figure, and edit the field.
Ethereum has no hard supply cap, so there is no honest fully diluted valuation to quote — the FDV rows stay empty unless you enter a total supply yourself. That is a genuine difference from capped assets: with ETH the question is not how much locked supply is waiting, but how fast new supply is issued relative to demand.
The comparison field answers the question people actually come here for: what would ETH be worth at some other valuation? Enter a target market cap and the calculator returns the implied ETH price and the multiple from here. It is arithmetic, not a forecast — reaching a larger cap means absorbing every holder willing to sell on the way, and eTH usually tracks BTC with a higher beta — bigger moves in both directions, especially around network upgrades.
The ETH price behind each market cap
- Circulating supply
- 121M ETH
- $10B cap →
- $82.85
- $100B cap →
- $828.5
ETH's circulating supply is about 121M (as of 31 Jul 2026). Market cap is only price × supply, so a target valuation pins one exact price — no guesswork.
A $1 billion cap would put ETH at $8.29, a $10 billion cap at $82.85, and a $100 billion cap at $828.5. ETH has no fixed cap here, so there is no fully-diluted denominator to add — the market-cap figure is the honest one.
Figures are derived from ETH's own daily closes over the window shown and are bounded by it — not all-time values. Prices move; treat them as context, not a forecast.

Frequently asked questions
- What is Ethereum's market cap?
- Multiply the live ETH price by the circulating supply — around 120.7 million ETH as of 31 July 2026. The calculator above loads the current price and does this for you; the result updates the moment you change either field.
- How do I calculate the ETH price at a given market cap?
- Divide the target market cap by the circulating supply. The comparison field above does it directly and also shows the multiple against today's ETH price, which is usually the more sobering number.
- Does Ethereum have a fully diluted valuation?
- Not a meaningful one. ETH has no fixed maximum supply, so there is no final coin count to price. Judge it on current market cap and the annual issuance rate instead of on FDV.
- How do you calculate crypto market cap?
- Market cap = current price × circulating supply. A coin at $2 with 500 million coins in circulation has a $1 billion market cap. Note that it is circulating supply, not total supply — tokens still locked in vesting contracts or a treasury are excluded.
- What is the difference between market cap and FDV?
- Market cap uses only the coins in circulation today. Fully diluted valuation (FDV) prices every coin that will ever exist, including locked and unminted supply. A project with a $200M market cap but a $2B FDV has 90% of its supply still to hit the market.
