# Cosmos Ecosystem SRB > **TL;DR:** All Cosmos SDK chains use the same base formula for staking rewards: annual provisions plus annualized daily fees, minus community tax, divided by total bonded tokens. This guide covers reward rate calculations for ATOM and 40+ Cosmos ecosystem chains. Welcome to the documentation on reward rate calculations for the Cosmos ecosystem. This guide provides comprehensive insights into how reward rates are calculated across the Cosmos network, including ATOM and other assets built on the Cosmos SDK. Whether you're a validator, staker, or simply interested in understanding the mechanics behind staking rewards, this documentation will walk you through the formulas, methodologies, and variables. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
