The Firestore Enterprise edition introduces apricingmodel that shiftsbilling from a "per document" basis to a "per unit" (or tranche) basis, andseparating the cost of real-time updates.

Note: The Enterprise edition is applicable only to a few regions.For more information on supported regions, seeLocations.

The following table details the cost per unit for both editions. The price shownis for us-central1.

Unit	Standard edition	Enterprise edition
Reads	$0.03 per 100k readsor $0.30 per million reads charged per document	$0.05 per million read units Read units are data processed (documents or indexes) when you read data from your database, calculated in 4 KiB tranches.
Writes	$0.09 per 100k writesor $0.90 per million writes charged per document	$0.26 per million write units Writes are measured in 1 KiB units. Index writes now cost write units. Note that indexing fields consume separate write units, so indexing a field with a 2KiB String incurs 2 write units.
Deletes	$0.01 per 100k deletes or$0.10 per million deletes	Utilizes Write units

Pricing Summary with Pipeline Operations

Read and Write Units: Based on Document Size

One of the differences in pricing between editions lies in how reads and writesare measured. In the Standard edition, costs are generally chargedper document. In the Enterprise edition, costs are charged per unitbased on document size:reads are in units of 4KiB, andwrites are inunits of 1KiB.

Scenario (Reading documents)	Standard edition (Charged per document)	Enterprise edition (Charged per unit)	Pricing highlights
Reading a large 8KiB document	Cost accrues1 read.	Cost accrues2 read units (8KiB /4KiB units, rounded up to 2 units).	Enterprise edition is cheaper. While Enterprise edition consumes more read units than Standard edition, the starting price for Enterprise edition read units is $0.05 per million read units v.s. $0.30 per million reads in Standard edition.
Scanning a collection with 20 documents at 1KiB each	Cost accrues20 reads	Collection scan: Cost accrues5 read units (20 documents * 1KiB = 20KiB total; 20KiB / 4KiB units = 5 units) Indexed scan: Cost accrues21 read units (20 document each at 1KiB looked up, 1 index read)	Enterprise edition is significantly cheaper when documents are small (1–2KiB average document size).

Indexing Cost: Index Writes Consume Units

In the Enterprise edition, indexes are not free; they consume writeunits when a document is written. Anadditional write unit is accrued foreach index-related field a document has.

Scenario (Writing a document)	Standard edition (No index write cost)	Enterprise edition (Index writes charged per 1KiB unit)	Pricing highlights
Writing a 5KiB document with 5 single-field indexes	Cost accrues1 write.	The document itself accrues5 write units (5KiB / 1KiB per unit) with5 additional write units for the 5 indexes, totaling to10 write units.	Indexing overhead makes large writes with multiple indexes incur more write units on Enterprise edition. While Enterprise edition consumes more write units than Standard edition, the starting price for Enterprise edition write units is $0.26 per million write units v.s. $0.90 per million writes in Standard edition.

Real-time Listen Queries Pricing

Real-time queries are divided into two distinct steps with separate pricingstructure:

• Initial query to sync results:Retrieves the initial set of data and is charged using Read Units.
• Real-time updates: Subsequent updates that reflect document changes after the initial query and are charged using real-time update units.

For each updated document, you pay one real-time update unit per 4KiB of data.

You are also charged one real-time update unit when a document is removed from the result set. In contrast, when a document is deleted, you are not charged for a read.

Billing of listeners in the mobile and web SDKS also depends on whether offline persistence is enabled or not:

• If offline persistence is enabled and the listener is disconnected for more than 30 minutes (for example, if the user goes offline), you will be charged as if you had issued a brand-new query and real-time updates thereafter.
• If offline persistence is disabled, you will be charged for documents and index entries read as if you had issued a brand-new query whenever the listener disconnects and reconnects and real-time updates thereafter.

Free tier usage for Real-time updates

The free tier applies to only one Firestore database per project. The firstdatabase that is created in a project without a free tier database will get thefree tier. The free tier for real-time update queries is 50,000 units per day.

After Free quota is consumed, the following pricing is applicable for Real-timeRead Units.
