Free tools, no email gate

FinOps calculators that do not waste your time.

Cloud cost tools should answer the question before they ask for a meeting. We built these because existing calculators often require sales calls or hardcode old assumptions.

Azure

AVD sizing calculator

Session host pool sizing for Azure Virtual Desktop. Concurrent users, profile workload, GPU need, host model, hours per month. Recommended SKU, host count, monthly run-rate, cost per user.

Azure

Azure Reservation ROI calculator

VM Reservations or Compute Savings Plans, 1 or 3 year, Up Front or Monthly. Monthly savings, effective discount, break-even when applicable. Hybrid Benefit aware.

GCP

GCP Committed Use Discount calculator

Resource-based and Flexible CUDs side by side. Monthly savings, total over the term, on-demand baseline. Notes on Sustained Use Discount stacking.

AWS

NAT Gateway cost calculator

The line item nobody budgets for. Hourly cost, data-processing cost, monthly total, and a checklist of the most common NAT cost drivers we catch in audits.

AWS

Reserved Instance break-even calculator

Standard or Convertible, 1 or 3 year, every payment option. Monthly savings, break-even month, net return over the term. Defaults you can override with your real EDP rate.

AWS

AWS Savings Plan ROI calculator

Plug in your on-demand spend, commit term, and payment option. Get monthly savings, break-even month, and net return over the term. Honest about the assumptions, no email gate.

Multi-cloud

Multi-cloud egress cost calculator

Side-by-side egress pricing for AWS, Azure, GCP, and Cloudflare R2. Tiered rates, region zones, cross-region option. Spots the workloads that cost less on R2 at a glance.

AWS

CloudWatch Logs cost calculator

Ingestion, storage tail, vended logs (VPC Flow / ALB / CloudFront), and Logs Insights queries side by side. Shows what cutting retention from 180 to 30 days would save. The line that surprises every team.

AWS

EBS gp2 vs gp3 cost calculator

Side-by-side gp2 vs gp3 cost on the same volume size, IOPS, and throughput. The most-missed savings line in AWS, with the migration command. No downtime, no detach.

AWS

S3 storage class cost calculator

Compare Standard, Intelligent-Tiering, Standard-IA, One Zone-IA, Glacier Instant, Glacier Flexible, and Deep Archive side by side. Storage, requests, retrieval, and minimum duration penalty all priced in.

Azure

Azure Blob storage tier cost calculator

Compare Hot, Cool, Cold, and Archive blob tiers side by side. Storage, transactions, retrieval, and minimum-duration penalty all priced in. LRS pricing for East US, North Europe, and Southeast Asia.

GCP

GCS storage class cost calculator

Compare Standard, Nearline, Coldline, and Archive Cloud Storage classes side by side. Storage, operations, retrieval, and minimum-duration penalty priced in. Single-region pricing for us-central1, europe-west1, and asia-southeast1.

AWS

AWS data transfer cost calculator

Cross-AZ, inter-region, VPC Peering, Transit Gateway, and outbound-to-internet on one page. Spots the data transfer line items that quietly add up to a third of the AWS bill, with the per-route fix for each.

AWS

VPC Endpoint cost calculator

Interface Endpoints (PrivateLink) versus Gateway Endpoints versus a NAT Gateway. Hourly endpoint cost, data-processing cost, and the break-even traffic where keeping the NAT Gateway is cheaper than swapping in PrivateLink.

AWS

Transit Gateway cost calculator

Per-attachment cost, data-processing cost, and the cross-AZ surcharge that hides on the EC2 data transfer line. Spots the unused attachments and the chatty VPC pairs that should be peered directly. The hub-and-spoke tax on multi-VPC AWS.

AWS

Lambda cost calculator

Invocation cost, GB-second cost, x86 vs ARM64 side by side, monthly total. Surfaces the three knobs that move the bill: memory tuning, architecture, duration. Spots the recursive triggers and the over-provisioned memory that quietly bills five figures a month.

AWS

Application Load Balancer cost calculator

Hourly base, LCU cost across four dimensions (new connections, active connections, processed bytes, rule evaluations), and the dimension that drives your bill. Spots the idle ALBs, the per-microservice consolidation savings, and the public-ALB-doing-east-west pattern that doubles the bill.

AWS

API Gateway cost calculator

REST API, HTTP API, and WebSocket API side by side. Surfaces the 71 percent saving from REST to HTTP API on most production workloads. Connection-minute math for WebSocket. The audit query and migration shape for the cutover.

AWS

CloudFront cost calculator

Zone-blended egress and request rates across all nine CloudFront regions, with a side-by-side comparison against raw S3 egress. Surfaces the price-class trick (100/200/All) and the workloads where the CDN is cheaper than going direct. The line that usually pays for itself.

AWS

AWS RDS cost calculator

Instance class, Multi-AZ, storage type, IOPS, read replicas, and RI options on one page, with a side-by-side against Aurora Standard and I/O Optimized. Surfaces the doubling effect of Multi-AZ, the gp3 saving, and the orphan-snapshot tax most teams miss.

AWS

DynamoDB cost calculator

Provisioned and on-demand priced side by side on the same workload, with the utilization tipping point that decides which is cheaper. GSI multiplier, PITR, streams, Standard-IA all priced in. Spots the on-demand tables that should be on provisioned and the provisioned tables that should be on on-demand.

Azure

Azure VM cost calculator

B-series, D_v5, E_v5, F_v2 across seven regions on one page. Linux, Windows, or Windows + SQL Standard with the per-vCPU licensing component spelled out. Hybrid Benefit, Reserved Instances, Savings Plans, and Spot stacked side by side so the maximum-saving combination is on the screen, not in a spreadsheet.
