Infracost shows cloud cost estimates for infrastructure-as-code projects such as Terraform. It helps DevOps, SRE and developers to quickly see a cost breakdown and compare different options upfront.
Show full breakdown of costs
Show diff of monthly costs between current and planned state
Assuming Terraform is already installed, get the latest Infracost release:
brew install infracost
Linux/macOS manual download:
# Downloads the CLI based on your OS/arch and puts it in /usr/local/bin curl -fsSL https://raw.githubusercontent.com/infracost/infracost/master/scripts/install.sh | sh

Run Infracost using our example Terraform project to see how it works:
git clone https://github.com/infracost/example-terraform.git cd example-terraform/sample1 # Play with main.tf and re-run to compare costs infracost breakdown --path . # Show diff of monthly costs, edit the yml file and re-run to compare costs infracost diff --path . --sync-usage-file --usage-file infracost-usage.yml
Please watch/star this repo as we add new cloud resources every week or so.
infracost CLI has the following main commands, their usage is described in our short getting started page:
breakdown: show full breakdown of costs
diff: show diff of monthly costs between current and planned state
As mentioned in our FAQ, no cloud credentials, secrets, tags or resource identifiers are sent to the Cloud Pricing API. That API does not become aware of your cloud spend; it simply returns cloud prices to the CLI so calculations can be done on your machine. Infracost does not make any changes to your Terraform state or cloud resources.
The following CI/CD integrations can be used to automatically add a pull request comment showing the diff of monthly costs between the current and planned state:
