# Understand your Grafana Cloud Traces invoice

Grafana Cloud calculates traces usage by looking at GBs ingested and GBs retained.

**GBs ingested**

The total number of GBs ingested into Grafana Cloud on a monthly basis.

**GBs retained**

How long trace data are retained within Grafana Cloud.

The minimum retention period is 30 days and you can purchase additional retention periods in 30-day increments.

Retention is customizable per stack. To enable this, contact Support.

## Billing calculations

Billing is based on usage, and usage is determined by these primary factors:

- The number of GBs ingested per month
- The number of months of retention

## View a usage summary

The Billing and Usage dashboard provides a usage summary for all Grafana Cloud services and billable data sources.

The **Billable Traces** section displays information about your current traces usage.

The **Traces Ingestion Details** sections in the **Usage Drilldown** provides detailed information about Trace ingestion Rate, Total Ingested Traces by day, and Discarded Spans.
