How to use this calculator

  1. Enter a coin's current price and circulating supply (or current market cap).
  2. Enter a target market cap — for example, 'what if it reached Ethereum's cap?'
  3. Read the implied price and the multiple from today's price.
  4. Sanity-check the number against total supply and realistic demand.

The theory behind it

A 'what if' market-cap projection answers a common question: what would this coin's price be if it reached the market cap of a larger one? Price = market cap ÷ circulating supply, so a target cap divided by supply gives the implied price. It's a useful reality check — coins with huge supplies need enormous caps to reach a modest price — but it's a thought experiment, not a forecast. Reaching a target cap requires real, sustained demand that may never materialise.

Frequently asked questions

How do I calculate a coin's price at a target market cap?

Divide the target market cap by the coin's circulating supply. For example, a $100B target cap with 10B coins in circulation implies a $10 price. The calculator does this for your inputs.

Should I use circulating or total supply?

For a near-term price, circulating supply is more realistic. Total (or fully diluted) supply gives a more conservative figure because future token unlocks add sell pressure. Comparing both is wise.

Is a market-cap comparison a price prediction?

No. It shows what price a given market cap would imply, but reaching that cap requires sustained real demand. Treat it as a scale check — especially for high-supply coins — not a forecast.
