Explainer: How crypto market capitalization, circulating supply and FDV are calculated — source‑reported guidance

Opening — what this explainer covers

This piece summarizes on‑record guidance reported by TokenPost about how cryptocurrency market capitalization is calculated and why the same token can show different market‑cap figures on different data sites.

It is a synthesis of TokenPost’s definitional and methodological explanations; it does not present new raw data or vendor‑level audits.

Essential reported facts

Market capitalization is an estimate of the value of an asset’s circulating units at the current token price, calculated from two inputs: the price of one token and an estimate of how many tokens are circulating (TokenPost).

Circulating supply is presented by TokenPost as the portion of tokens considered available in the market or in public hands; it is distinct from total supply and maximum supply (TokenPost).

TokenPost reports that providers use different methods to estimate circulating supply — including reviewing trading venues and liquidity, using token‑team disclosures, examining trading volume, and sometimes excluding locked tokens — so different providers can publish different circulating‑supply estimates for the same token.

Fully diluted valuation (FDV) is described by TokenPost as applying the current token price to a broader supply figure such as total or maximum supply; TokenPost warns FDV definitions vary between providers and should be checked when comparing figures.

How market capitalization works — reported mechanics

TokenPost explains that the market‑cap calculation multiplies token price by an estimate of circulating supply; either input — price or circulating supply — changing will change the market‑cap result.

The report emphasizes market capitalization does not measure how much cash investors have put into an asset, nor how much could be raised if holders tried to sell; it is a derived metric from price and supply, not a cash tally (TokenPost).

TokenPost highlights that supply changes such as token unlocks, mining or staking rewards, or token burns alter market capitalization when supply is an input, and price moves will alter market capitalization even if supply is unchanged.

• Inputs: token price and an estimated circulating supply.
• Market cap moves when price or circulating supply changes.
• Market cap is not a direct measure of cash invested or liquidity available.

Why different data sites report different market caps — reported causes

TokenPost lists several common reasons for differences between providers’ market‑cap figures: variation in circulating‑supply definitions, different sources for supply estimates (exchange listings vs. team disclosures), exclusion or inclusion of locked tokens, and differences in which assets or markets each provider covers.

TokenPost advises readers comparing market‑cap numbers should check which supply definition a provider uses and whether the same definition is applied consistently across comparisons; substituting one supply measure for another changes the calculation.

What FDV and dominance mean, as reported

TokenPost explains FDV applies the token’s current price to a broader supply figure (total supply or maximum supply) and that FDV is not a separate count of cash invested — it is a hypothetical value contingent on the supply definition used.

TokenPost also explains Bitcoin dominance is calculated as Bitcoin’s market capitalization divided by the combined market capitalization of all cryptocurrencies and that it expresses Bitcoin’s share of that combined total, not trading activity.

Significance of these distinctions — reported guidance

According to TokenPost, using price with different supply measures can materially change a token’s reported market capitalization and FDV, which matters for comparisons between tokens and assessing relative scale.

TokenPost recommends reading price, market capitalization, supply and trading measures together to get a fuller description of an asset’s market, because each measure captures a different part of the picture.

Analysis — what readers should take away

TokenPost’s reporting is a definitions‑first guide: market cap is a derived metric, and because supply estimation methods differ, market‑cap numbers are only as comparable as the supply definitions behind them.

When you see discrepancies across CoinMarketCap, CoinGecko or other aggregators, the most likely explanation — per TokenPost — is a differing circulating‑supply methodology rather than a disagreement about token price alone.

Practical reader questions and steps

Which supply measure does this site use? Check the provider’s methodology page for its definition of circulating supply, total supply and maximum supply.

Does the provider exclude locked tokens or use team disclosures? Look for notes on locked allocations, vesting schedules and how on‑chain balances or exchange lists are treated.

Am I comparing like with like? Ensure the same supply definition and reference time are used when comparing market‑cap or FDV figures across sources.

• Check provider methodology pages.
• Verify whether locked tokens or team allocations are excluded.
• Compare the same supply definition across sources before drawing conclusions.

Current status and limitations of this explainer

This article summarizes TokenPost’s on‑record reporting and definitions; it does not replace vendor documentation or per‑asset supply reconciliations.

TokenPost is the single source for these explanations in this report; vendor‑level methodologies and raw data were not provided here and remain the next step for deeper verification of supply figures.

Closing — what we confirmed and what remains open

Confirmed: TokenPost’s definitions that market capitalization uses token price and circulating supply, the distinction between circulating/total/max supply, that providers use differing methods to estimate supply, and that FDV applies price to a broader supply figure are accurately reported here.

Open: Specific per‑provider or per‑asset supply calculations, reconciliations and raw data are not provided in TokenPost’s explainer and would be required to reconcile divergent market‑cap numbers for a particular token.
