 # Data Warehouse Costs and Savings with Tobiko
 
-Tobiko Cloud tracks data warehouse cost estimates per model for BigQuery and Snowflake projects. It will also estimate cost savings achieved by SQLMesh intelligently detecting when a model doesn’t need to be rerun.
+Understanding and managing data warehouse costs is challenging. Tobiko Cloud helps by tracking your data warehouse costs and integrating them into the Tobiko Cloud UI.
 
-If you'd like to see cost and savings estimates in Cloud and use a supported pricing plan, Tobiko can estimate your data warehouse costs for you and display them in various places on Tobiko Cloud.
+Tobiko Cloud tracks data warehouse cost estimates per model for BigQuery and Snowflake projects. It also estimates how much money Tobiko Cloud has saved you by skipping unnecessary model reruns.
 
 ## Supported Data Warehouse Pricing Plans
 
+Tobiko Cloud supports costs and savings data for these data warehouse pricing plans:
+
 - BigQuery On Demand
 - Snowflake Credits
 
 ## Data Warehouse Cost Configuration
 
-If you use one of the supported pricing plans, in order to configure Tobiko Cloud to show cost information you will need to visit Settings.
+If you use a supported pricing plan, visit Settings to configure Tobiko Cloud's cost estimates.

 On the General settings page (1), select your pricing plan (2), enter your costs, and then save (3).

 Estimated costs and savings are displayed on the homepage, production environment page, runs and plans pages, and individual model pages.
 
-Cost information on each page will look similar to the following:

 ### Savings Categories
 
-When calculating your data warehouse costs, we will calculate the amount you saved by using Tobiko as well! Tobiko Cloud also comes with additional change categorization capabilities, such as advanced column-level impact analysis.

+Tobiko Cloud comes with even more change categorization capabilities than open-source SQLMesh, such as advanced column-level impact analysis.
 
 Cost savings are broken up into three main categories:
 
-- **Prevented Reruns**: If SQLMesh has already run an execution for a change in one environment, we won't need to rerun it in another environment (such as when a model change is backfilled on a development environment and then applied to prod)
-- **Unaffected Downstream**: Because SQLMesh understands SQL, we know if a downstream model is not affected by an upstream change and can avoid re-execution.
-- **Virtual Environments**: Using the Virtual data environments feature means new environments can be created without backfilling models within the new environment.
+- **Prevented Reruns**: If SQLMesh already executed a change in one environment, we won't rerun it in another environment (backfills from development environments are reused when it is safe to do so).
+- **Unaffected Downstream**: SQLMesh understands SQL, so we skip re-execution if a downstream model is not affected by an upstream change.
+- **Virtual Environments**: With Virtual data environments, new environments can be created without running any computations at all.
