Google Cloud Platform (GCP) offers a vast array of services, each with its own pricing model. Accurately estimating these costs is crucial for budgeting, resource optimization, and making informed decisions about your cloud infrastructure. This calculator provides a simplified estimation for some of the most common GCP services: Compute Engine, Cloud Storage, and Network Egress.
Key Cost Components:
Compute Engine: This is GCP's Infrastructure-as-a-Service (IaaS) offering, providing virtual machines (VMs). Costs are typically based on the number of vCPUs, memory, machine type, operating system, and the duration the VM is running. Our calculator simplifies this by using a direct price per vCPU hour.
Cloud Storage: GCP offers various storage classes (Standard, Nearline, Coldline, Archive) with different pricing for storage capacity, operations (like reads and writes), and network egress. This calculator uses a simplified price per GB per month for stored data.
Network Egress: This refers to data transferred out of Google Cloud to the internet or to certain other Google Cloud regions. Costs can vary significantly based on the destination and volume of data. Our calculator uses a price per GB per month for egress traffic.
How the Calculation Works:
The calculator uses a straightforward formula to estimate the total monthly cost:
Total Monthly Cost = (Compute Engine Hours * Compute Engine Price per Hour) + (Storage GB * Storage Price per GB) + (Network Egress GB * Network Egress Price per GB)
Each input field represents a specific metric for these services. For example, "Compute Engine Hours" is the total number of virtual CPU hours you expect to consume in a month, and "Compute Engine Price" is the cost associated with one vCPU hour for your chosen machine type and region.
Use Cases for this Calculator:
Initial Project Budgeting: Estimate the potential monthly spend for a new application or service hosted on GCP.
Resource Planning: Determine how changes in usage (e.g., more VMs, increased storage) will impact your cloud bill.
Cost Optimization: Compare the costs of different configurations or services to identify potential savings.
Educational Purposes: Understand the basic pricing structure of core GCP services.
Important Considerations:
This calculator provides a simplified estimate. Actual Google Cloud costs can be influenced by many other factors, including:
Specific machine types and configurations for Compute Engine.
Different Cloud Storage classes (Standard, Nearline, Coldline, Archive).
Network ingress (data coming into GCP) is generally free.
Costs for other GCP services like BigQuery, Cloud Functions, AI Platform, databases (Cloud SQL, Spanner), load balancing, monitoring, etc.
Sustained usage discounts and committed use discounts offered by Google Cloud.
Support plans.
Taxes.
For precise cost estimations, always refer to the official Google Cloud Pricing Calculator and consult GCP documentation.
