Ethereum Calculators

No fixed cap is published for Ethereum, which is why no maximum is shown on this page — we leave the figure out rather than invent a denominator. Circulating supply was 120.7 million ETH as of 31 July 2026. Without a cap, the number that matters is the net issuance rate: new supply minus anything burned, as a percentage per year.

Yes. Run a 32 ETH validator, join a staking pool, or hold a liquid staking token such as stETH or rETH which stays tradeable while it earns. Rewards run at roughly 2.5–4% in recent years, and the calculator on this page is prefilled with 3% so you can change it to whatever your validator or platform actually quotes. No fixed lock, but entering and exiting the validator set both go through a queue that can take days when demand is high. Staking is native to the protocol here, so you are not relying on a third party's wrapper.

There are 6 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 ETH 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 ETHUSDT 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.
