+### Estimating costs
+
+To estimate costs, use [infracost](https://www.infracost.io/docs/).
+
+For example:
+
+```bash
+cd terraform/aws
+infracost breakdown --config-file infracost.yml
+```
+
+To estimate costs accounting for usage-based pricing:
+
+```bash
+cd terraform/aws
+infracost breakdown --config-file infracost.yml --sync-usage-file
+# edit iglu_server/default/infracost-usage.yml
+# edit pipeline/default/infracost-usage.yml
+infracost breakdown --config-file infracost.yml
+```
+
