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.
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 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 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.
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.
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 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 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.
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.
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.
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 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.
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 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.
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.
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.
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.
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.
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.
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 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.
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 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.
