How to Use Market Cap Calculator
The Market Cap Calculator supports three calculation modes so you can solve for any unknown in the market cap equation.
- Calculate Market Cap — Enter the price per share or coin and the circulating supply. The Market Cap Calculator instantly returns the total market capitalization.
- Reverse-calculate Price — Enter the known market cap and circulating supply to find the implied price per unit.
- Reverse-calculate Supply — Enter the known market cap and current price to find the implied circulating supply.
Results are displayed with abbreviated suffixes (K, M, B, T) for readability, plus the full numeric value for precision. No sign-up or download is required to use the Market Cap Calculator.
Formula & Theory — Market Cap Calculator
The Market Cap Calculator is built on one foundational formula:
Market Cap = Price per Unit × Circulating Supply
The two reverse modes simply rearrange this relationship:
Price per Unit = Market Cap ÷ Circulating Supply
Circulating Supply = Market Cap ÷ Price per Unit
| Symbol | Meaning |
|---|---|
| Market Cap | Total market value of the asset |
| Price per Unit | Current trading price per share, coin, or token |
| Circulating Supply | Total number of units currently in circulation |
The Market Cap Calculator makes no assumptions about currency — enter any consistent unit and the result will be in the same unit.
Market Cap vs. Fully Diluted Valuation
Circulating supply includes only tokens or shares currently available in the market. Fully diluted valuation (FDV) uses the maximum possible supply instead. The Market Cap Calculator focuses on circulating supply, which is the standard metric reported on most financial and crypto data platforms.
