EthereumPrice.org has released the Eth2.0 staking reward calculator tool, which is currently in public beta. This tool can calculate the ETH rewards and cumulative investment return that can be obtained every year for 10 years of ETH pledge. Users can choose a variety of fiat currencies to display the value of their pledged ETH, including US dollars, euros, pounds, yen and so on. Users can calculate the rewards by adjusting the network settings. For example, setting the amount of staking ETH to 1% of the total circulation will mean that the pledgee can obtain an annual rate of return of 5%, and if it is set to 10%, the pledgee will be able to obtain 15% annual rate of return.
