Cloud Run cost, second by second.
Turn requests, request duration, vCPU and memory into a monthly Cloud Run bill, with the free tier applied.
Request-based cost = (vCPU-seconds − 180,000) × $0.000024 + (GiB-seconds − 360,000) × $0.0000025 + (requests − 2M) × $0.40 per million. Time is rounded up to the nearest 100 ms. Rates are us-central1 (Tier 1).

Method and limits
In request-based billing, billable time per request is the duration rounded up to the next 100 ms. Instance-seconds are requests × billed seconds ÷ concurrency, then multiplied by vCPU and GiB to get vCPU-seconds and GiB-seconds. Concurrency above 1 assumes instances are kept full, so treat it as a best case. Minimum instances add idle time, charged at Google’s idle rates ($0.0000025 per vCPU-second and per GiB-second), for the part of the month they are not serving requests. Instance-based billing charges every second an instance is allocated, with no per-request fee.
Not included: Cloud Run networking and egress (see the GCP egress calculator), build, Artifact Registry, logging, committed-use discounts, other regions, GPUs and Cloud Run functions.

Frequently asked questions
How is Cloud Run billed?
Google lists two modes. Request-based billing charges CPU and memory while a request is being handled, plus a per-million request fee. Instance-based billing charges CPU and memory for the full time an instance is allocated, with no request fee. Usage is rounded up to the nearest 100 ms.
What is the Cloud Run free tier?
For request-based billing Google lists 180,000 vCPU-seconds, 360,000 GiB-seconds and 2 million requests free each month, applied using us-central1 pricing. Instance-based billing lists 240,000 vCPU-seconds and 450,000 GiB-seconds. The tool applies them when the checkbox is on.
Does the calculator include egress?
No. Outbound internet traffic from Cloud Run is billed under Google Cloud network pricing, so use the GCP egress cost calculator and add the two.
Why does concurrency lower the bill?
When an instance handles several requests at once they share its CPU and memory, so instance-seconds fall. The tool divides billed time by concurrency, which is only accurate when instances stay busy.
