EverStake Calculator
Staking pools are chain-specific. This model takes into account the daily volume in usd on a specific chain (4% goes to stakers), your bag size, the staking pool size (both in RISE), your chosen staking term and an assumption on the average staking term for the rest of the pool.
Use this option to establish if your bag size is already included in the staking pool size (already staking) or not. For small bags, the difference is not relevant, but as the bag grows, the difference is more noticeable. If advanced settings is hidden, the default value is 'already staking'.
