Crypto market cap calculator

Market cap is price times circulating supply; fully diluted valuation uses the max supply instead. The gap between them — how much supply is still to be unlocked — is often the real story, so it shows the circulating share too. Also answers the reverse: the price implied by a target market cap.

Frequently asked questions

How does the Crypto market cap calculator work?

It takes Price, Circulating supply and Max supply and derives Market cap, Fully diluted valuation and Circulating share of max from them. The calculation is live as you type, so the result updates on every change.

Which values does the calculator ask for?

3 values: Price ($), Circulating supply and Max supply. Nothing else is required — no account, no file upload.

What does a typical calculation look like?

With Price = $2.50, Circulating supply = 400,000,000 and Max supply = 1,000,000,000, the calculator returns Market cap = $1,000,000,000.00, Fully diluted valuation = $2,500,000,000.00 and Circulating share of max = 40%. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

How much does the result change with different inputs?

It moves a lot. Using Price = $5.00, Circulating supply = 800,000,000 and Max supply = 2,000,000,000 instead, Market cap goes from $1,000,000,000.00 to $4,000,000,000.00 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Price = $1.25, Circulating supply = 200,000,000 and Max supply = 500,000,000, Market cap comes out at $250,000,000.00. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Comparing two investments that pay at different times, deciding whether a project clears its cost of capital, and sanity-checking a valuation someone else produced.

What is the most common mistake?

Trusting a valuation without asking what share of it comes from the terminal value. Past 70%, the answer is an assumption about the distant future dressed up as a calculation.

How accurate is it, and what are the limits?

Estimate only — not financial or tax advice. Exchange formulas vary.

What is the difference between the Crypto market cap calculator and the Crypto lending / borrowing calculator?

This one returns Market cap and Fully diluted valuation; the Crypto lending / borrowing calculator returns Current LTV and Health factor. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Crypto DCA calculator is the closest one after this: Dollar-cost averaging: enter your fixed buy amount and the prices you bought at, and get coins accumulated, true average cost, current value and profit/loss. Break-even is your average cost — you are ahead the moment price passes it.

It is a model, not arithmetic: at a daily autocorrelation of 0.1 a 60 percent annualised figure should read 66.3. The payload is volatility drag — the arithmetic mean exceeds the geometric by about σ²/2, so at 8 percent average return and 40 percent volatility the compound outcome is zero.
