Market Cap, Price & Supply Calculator

Solve the crypto valuation triangle offline: enter two of market cap, price and circulating supply, leave one blank, and the calculator finds the missing side.

No price feed, no network call — the math runs entirely in your browser on the numbers you type.

Accepts suffixes: 1.5M, 20B, 3T (K/M/B/T). Fill the two visible fields — the hidden one is what gets calculated.

How It Works

Three numbers form a triangle: market cap = price × circulating supply. Fill any two and leave the third blank — the calculator solves the missing side. Worked example: a $10B market cap with 5B tokens circulating gives 10B ÷ 5B = $2.00 per token.

The triangle relation
Price is just market cap divided by supply; supply is market cap divided by price; market cap is the product. It is an identity, not a model: at any instant the quoted spot price and circulating supply pin the cap exactly (marketCap = price × supply), so whatever you leave blank is forced by the other two.
Circulating vs max supply (FDV)
Which supply number you enter changes the answer completely. Circulating supply gives the classic market cap; using max supply gives the fully-diluted valuation — same math, different number. A token with 1B circulating, 21B max and a $5 price is a $5B market cap but a $105B FDV, and comparisons only make sense when both sides use the same definition.
Why tiny prices need many decimals
Splitting a large supply into a mid-size cap produces sub-cent numbers fast: 1B market cap ÷ 1T supply = $0.001. Results show up to eight decimal places for prices under $1, because rounding $0.00004321 to $0.00 would silently erase two orders of magnitude — the digits are the information.

Frequently Asked Questions

Does this account for future dilution?

No — and the reason is in the inputs. The same price implies a completely different valuation depending on whether you divide by circulating supply, total supply or max supply. This calculator just inverts the arithmetic; which supply number you use is your decision. For a fair comparison across assets, pick one supply definition and stick with it.

What is the difference between market cap and FDV?

Market cap multiplies the current price by the circulating supply — what exists and trades today. Fully diluted valuation (FDV) multiplies the same price by the maximum (or total) supply as if every future token had already been emitted: using max supply gives fully-diluted valuation — same math, different number. When much of the supply is still locked or vesting, FDV can dwarf market cap, and many analysts watch the FDV/market-cap ratio as a dilution gauge.

Is this investment advice?

No. It is arithmetic — price × circulating supply = market cap, solved for whichever value you leave blank. It knows nothing about an asset's fundamentals, token schedule, liquidity or risk, and it does not recommend anything. Treat every output as a number-crunching convenience, not a thesis.

Why does my price result show so many decimals?

Because low-unit-price assets need them: a $100 billion market cap spread over 100 trillion tokens of supply is exactly $0.001 per token, and one more zero is another order of magnitude. Results show up to 8 decimals for sub-$1 prices so meme-scale numbers stay meaningful; for normal rounding, the trailing decimals are simply precision your inputs implicitly carry.

Is anything uploaded to a server?

No. There is no live price feed here on purpose: every value comes from the boxes you fill in and the arithmetic runs entirely in your browser. Your inputs and results never leave your device.
