Explore by cost driver
The same 33 tools, grouped by what is actually moving the bill rather than by whose cloud it is on. Use this when you know the symptom but not the service: an egress problem does not announce whether it belongs to a NAT gateway, a CDN, or pods talking across zones.
Compute and utilisation
Instances and functions that are larger than the work needs, or running when nobody needs them. Usually the largest single line and almost always the one with the least risk attached to changing it.
Cloud Workload Carbon Calculator
Where you run it matters more than what you run it on: by a factor of hundreds.
EC2 Idle & Rightsizing Calculator
What idle instances cost, and what stopping them actually saves.
RDS Cost & Rightsizing Calculator
Multi-AZ doubles more than you think. Price it before you enable it.
Lambda Cost & Memory Tuning Calculator
The cheapest memory setting, and the fastest one that costs the same.
Fargate vs EC2 Calculator
Per vCPU Fargate looks dear. Per cluster it often is not.
Azure VM Cost Calculator
Real Spot rates, an honest band for reservations.
Cloud Run Cost Calculator
Two billing models, and utilisation picks the winner.
GCP Sustained & Committed Use Discount Calculator
A commitment replaces your sustained-use discount. It does not add to it.
Databricks Cost Calculator
The DBU line is a third of the bill. This prices the other two thirds.
Kubernetes Cost Calculator
Size the nodes from your pod requests: then price what nodes leave out.
Storage and lifecycle
Data sitting in a class it does not need. The trap is always the same: retrieval charges, per-object minimums and early-delete fees eat the storage saving that motivated the move.
EBS gp2 vs gp3 Calculator
The easiest 20% in AWS: unless your volume needs paid IOPS.
S3 Storage Class Calculator
Where the break-even really is, once transitions and minimums are counted.
CloudFront vs S3 Direct Calculator
Object size decides this, not cache hit rate.
Azure Managed Disk Calculator
Azure bills disks by SKU, not by the space you use.
Azure Blob Storage Tier Calculator
Hot, Cool, Cold and Archive: with the early-delete fee counted.
Cloud Storage Class Calculator
On Google, operations decide this more often than storage does.
Network and data transfer
The charges that do not appear on any instance line. Gateways billed by the hour and by the gigabyte, egress tiers, and traffic that costs money simply for crossing a zone boundary inside your own region.
NAT Gateway & Data Transfer Calculator
Price the line item that surprises everyone, and find the cheaper shape.
CloudFront vs S3 Direct Calculator
Object size decides this, not cache hit rate.
Kubernetes Cost Calculator
Size the nodes from your pod requests: then price what nodes leave out.
Kubernetes and containers
Where the bill is set by what pods requested rather than what they used, and where the control plane, load balancers and node disks add up to more than people expect.
Fargate vs EC2 Calculator
Per vCPU Fargate looks dear. Per cluster it often is not.
Cloud Run Cost Calculator
Two billing models, and utilisation picks the winner.
Kubernetes Cost Calculator
Size the nodes from your pod requests: then price what nodes leave out.
Databases and caching
Managed engines where the replica, the standby and the storage multiply the headline instance price, and where capacity mode is worth more than instance size.
RDS Cost & Rightsizing Calculator
Multi-AZ doubles more than you think. Price it before you enable it.
DynamoDB On-Demand vs Provisioned
The break-even is a utilisation, not a traffic level.
ElastiCache Cost & Reserved Nodes
Replicas are nodes. Cross-AZ replication is a bill.
Analytics and warehouses
Query engines billed by bytes scanned, credits burned or slots reserved. The lever is nearly always the query or the idle warehouse, not the rate.
BigQuery Slot vs On-Demand Advisor
Find out whether BigQuery Editions slots would actually save you money.
BigQuery Query Cost Analyzer
What this query actually costs: computed, not guessed.
BigQuery FinOps Query Pack
Copy-paste SQL for the cost questions you ask at 4pm during an incident.
Snowflake Cost Calculator
Credits burn by the second your warehouse is awake, not while it works.
Warehouse Cost Translator
What would this BigQuery workload cost on Snowflake or Databricks?
Databricks Cost Calculator
The DBU line is a third of the bill. This prices the other two thirds.
AI and model usage
Token spend, and the loop around it. Agentic workloads multiply a per-call price by steps, fan-out, retries and a context window that grows as it goes.
Billing data, allocation and governance
The work that makes every other number trustworthy: knowing what moved, what it belongs to, and whether the export conforms to a standard anyone else can read.
BigQuery FinOps Query Pack
Copy-paste SQL for the cost questions you ask at 4pm during an incident.
Cloud Bill Diff
Why did the bill go up? Separate the rate change from the usage change.
Cost Allocation Score
Grade your tagging against the FinOps Foundation KPI, in one file drop.
FOCUS 1.4 Validator
Check a billing export against FOCUS 1.4: no size cap, nothing uploaded.
GCP Billing SKU Dictionary
What that mystery line on your Google Cloud bill actually is.
Cloud & AI Cost Readiness Assessment
Score your FinOps practice against the four framework domains.
Pricing and commitments
Discount mechanics and what the vendor changed this week. Commitments interact with each other in ways that are not always additive and are occasionally negative.
BigQuery Slot vs On-Demand Advisor
Find out whether BigQuery Editions slots would actually save you money.
GCP Billing SKU Dictionary
What that mystery line on your Google Cloud bill actually is.
Cloud Pricing Change Tracker
What changed in AWS, GCP, and Azure pricing: before your bill tells you.
Azure VM Cost Calculator
Real Spot rates, an honest band for reservations.
GCP Sustained & Committed Use Discount Calculator
A commitment replaces your sustained-use discount. It does not add to it.
Carbon and sustainability
The same workload, priced in emissions rather than dollars. Location moves this by hundreds of per cent where the operator moves it by a few.
Cloud Workload Carbon Calculator
Where you run it matters more than what you run it on: by a factor of hundreds.
Cloud Carbon Coefficients
The emission factors behind the CO₂e line: and where we refuse to show one.
Finitizer watches every one of these drivers continuously
These tools price one driver at a time against numbers you supply by hand. Finitizer connects read-only and keyless, evaluates all of them daily against your live accounts, and ships the fix as a Terraform pull request or a Jira ticket.
