Estimate AlloyDB cost
Forecast AlloyDB N2 compute and regional storage with this calculator; keep backup, network, and discount assumptions separate.

Compute, storage, and network are distinct
This AlloyDB calculator models N2 vCPU-hours, memory GiB-hours, and regional storage GiB-hours in Iowa. Google describes AlloyDB pricing as consumption based and also lists network egress as a driver. Backups, networking, extended support, taxes, and discounts are excluded from this tool.
For rate-free math, a primary with 8 vCPUs and 64 GB for 730 hours represents 5,840 vCPU-hours and 46,720 GB-hours. Add 2,000 GB-months of storage, backup quantity, read-pool hours, and outbound bytes. Apply the relevant current price sheet.
Use the AlloyDB Cost Calculator for the three modeled resource quantities and revise it from billing data.
FAQ
Is storage coupled to compute?
Google describes a disaggregated design, so model storage independently.
