Market Cap / Price / Supply Calculator

Market cap = price × supply. Leave one of the three blank to solve it; fill all three to cross-check and see the consistency gap.

Results

Fill in at least two inputs and click Calculate.

Risk disclaimer

Outputs depend on the market-cap / supply convention you enter; sources may differ.

What does this do?

It solves the price / circulating supply / market cap triangle in one place: any two determine the third.

Data sources differ on what counts as circulating (locked, staked, etc.), so keep the same convention when comparing.

How to use

  1. Fill any two of market cap, price and supply, leaving the one to solve blank.
  2. With all three filled, Calculate uses price × supply as the base and reports the gap.
  3. Click Calculate to see the derived market cap / price / supply.

Formula

  • Market cap = price × supply
  • Price = market cap ÷ supply
  • Supply = market cap ÷ price

Example

Price 5 and supply 100 → market cap 500.

Entering 520 against the 5 × 100 = 500 base shows a +4.0% gap, flagging inconsistent sources.

FAQ

Why prefer two-of-three?

Two inputs give a unique result; three inputs expose source inconsistencies, useful for auditing data.

Is this valuation advice?

No. It is unit conversion only and says nothing about fair value.
