GA4 BigQuery Export Cost Forecaster
Translate your Google Analytics 4 export volume into tangible BigQuery costs. Enter daily exported events and the terabytes you scan each month, then optionally adjust event size, retention window, and published rates to project storage, streaming ingest, query spend, and effective cost per million events.
BigQuery pricing varies by region, commitment plan, and data reduction techniques. Validate these assumptions with your Google Cloud account team before finalizing budgets.
Examples
- 8 million daily events, 12 TB queries, 1.3 KB events, 30-day retention ⇒ Active storage footprint: 304,687.50 GB • Active storage cost: $6,093.75 USD • Streaming ingest cost: $3,046.88 USD • Query cost: $72.00 USD • Total monthly BigQuery cost: $9,212.63 USD • Cost per million exported events: $38.39 USD
 - 15 million daily events, 25 TB queries, 1.6 KB events, 45-day retention, custom rates ⇒ Active storage footprint: 1,054,687.50 GB • Active storage cost: $22,148.44 USD • Streaming ingest cost: $9,492.19 USD • Query cost: $137.50 USD • Total monthly BigQuery cost: $31,778.13 USD • Cost per million exported events: $70.62 USD
 
FAQ
How do reserved slots change the math?
Set the query rate to $0 if you are on flat-rate or enterprise capacity for GA4 queries. You can then add your monthly slot commitment separately for a full picture.
Can I include Looker Studio extract costs?
Yes. Estimate the additional terabytes scanned by Looker Studio or scheduled queries and add them to the query TB field so the output includes that usage.
What about long-term storage pricing?
This tool focuses on active storage. If you keep partitions longer than 90 days, use the same footprint output with BigQuery's $0.01/GB long-term rate for a supplemental estimate.
Does this cover export to data warehouse alternatives?
No. The assumptions match BigQuery pricing. For Snowflake or Redshift, adjust the storage and query rates to mirror those platforms.
Additional Information
- Event size defaults to 1.3 KB per row, which reflects typical GA4 payloads with a handful of custom parameters.
 - Retention represents the hot data window you keep in active storage; older partitions can be moved to long-term storage outside this model.
 - Streaming ingest cost is estimated using BigQuery's default $0.01/GB rate—update it if you batch-load via Cloud Storage.
 - Cost per million events lets marketing teams benchmark GA4 export spend against media budgets or analytics ROI targets.
