Bitcoin Calculators

20.06 million BTC were in circulation as of 31 July 2026, against a maximum of 21 million — so 95.5% of everything that will ever exist has already been issued, leaving 940,000 still to come. At that point issuance is close to finished, so future supply growth is not a meaningful factor in the price.

None — Bitcoin is mined, not staked. That is why there is no BTC staking calculator here: the tool reports rewards in units of the coin you staked, so it only covers networks that pay in that same asset. Publishing a page where the dollar figure was right and the unit was wrong would be worse than leaving it out.

There are 5 on this page and they answer different questions. Start from what you are actually asking: what a past purchase would be worth now, what a position is worth today, where a leveraged position gets liquidated, or what regular buying would have produced. Each opens with the live BTC price already filled in, and every calculation runs in your browser — nothing is sent anywhere and nothing is stored.

Live from CoinGecko when you press the price button, with the BTCUSDT pair on Binance as a fallback if that request fails. The request happens in your browser and carries nothing about you; if both fail the calculator keeps working with whatever figure you type in.
