Cloud & Infrastructure calculators

50 live cloud & infrastructure calculators inside Technology & Computing on The Online Calculator 24. Every engine shows its formula, the worked steps behind the default figures, and the standard or dataset the method comes from.

Live Cloud & Infrastructure tools

• Cloud Cost Estimate Calculator — Estimate a monthly cloud bill from compute instances, storage and data transfer — with the classic cost pitfalls flagged.
• AWS EC2 Cloud Compute & Reserved Savings Calculator — Calculate AWS EC2 monthly server expenses, attached EBS gp3 block storage, outbound network egress, and savings across 1-Year/3-Year Savings Plans and Spot instances.
• AWS S3 Cost Calculator — What a bucket actually bills: storage class rate plus request charges plus egress — the three lines lifecycle policies trade against each other.
• AWS RDS Cost Calculator — Managed database pricing: instance-hours, gp3 storage, Multi-AZ duplication and the backup line that people forget.
• AWS Lambda & Serverless Compute Cost Calculator — Calculate AWS Lambda compute charges, memory GB-seconds, invocation fees, free-tier credits, and compare ARM Graviton2 vs. x86_64 architectures.
• AWS EKS Cost Calculator — What an EKS cluster bills: the $0.20/hr control plane plus your nodes and disks — Kubernetes itself adds no license fee.
• Azure VM Cost Calculator — Windows/Linux VM pricing with managed disk and the reserved-instance ladder at list rates — the Azure equivalent of the EC2 sheet.
• Azure Storage Cost Calculator — Blob storage cost at the hot tier for each redundancy option, plus transactions and the egress tier.
• Azure SQL Cost Calculator — DTU-based Azure SQL Database pricing: the tier floor, extra storage, and the reservation discount ladder.
• Azure Functions Cost Calculator — Consumption-plan billing for Azure Functions at list rates — executions and GB-seconds, both with generous free grants.
• GCP Compute Cost Calculator — Compute Engine pricing with GCP’s distinctive automatic sustained-use discount plus committed-use ladders and PD-SSD disk.
• GCP BigQuery Cost Calculator — On-demand BigQuery billing: scanned bytes at $5/TB plus storage and streaming lines — with partitioning as the tuning lever.
• GCP Cloud Run Cost Calculator — Scale-to-zero container billing on Cloud Run — requests, vCPU-seconds and GiB-seconds with the free grant removed.
• Hybrid Cloud Savings Calculator — Whether splitting steady load on-prem with cloud only for burst actually saves, at your real price factors and burst share.
• Multi-Cloud Arbitrage Calculator — The honest math of moving a workload to a cheaper provider: the discount gap minus egress, staff context-switching and duplicated tooling.
• Reserved Instance Savings Calculator — Whether a reserved/committed discount actually saves money at your real utilization — the arithmetic FinOps dashboards usually skip.
• Spot Instance Savings Calculator — Real spot-interruptible savings once interruption retries are priced in, not just the headline 70 % discount.
• Savings Plan Benefit Calculator — True Savings Plan economics once you subtract idle commitment — coverage above your P50 usage converts discount into waste.
• Right-Sizing Savings Calculator — The annual cash from stepping oversized instances down a size — with the CPU-headroom projection that keeps it from being a capacity incident.
• Idle Resource Cost Calculator — What unattached disks, parked IPs, stopped instances and orphaned snapshots quietly cost every month.
• Auto-Scaling Cost Calculator — The money elastic scaling returns versus a fleet provisioned at peak, from your real peak-to-baseline ratio.
• Load Balancer Cost Calculator — Application Load Balancer billing: the hourly base, the LCU traffic dimension, and per-cert / per-target-group add-ons.
• CDN Cost Calculator — CDN delivery spend net of the origin-egress it replaces — the correct way to price caching, not on list per-GB alone.
• Data Transfer Cost Calculator — The cross-boundary data bill for a flow: free inbound, two-cent AZ and region hops, nine-cent internet egress.
• Egress Cost Calculator — The tiered internet-egress ladder applied to your volume — the single line that dominates cloud media bills.
• Ingress Cost Calculator — What getting data into your cloud actually costs once the path is chosen — the line people assume is free.
• Cross-Region Cost Calculator — The recurring bill of warm-standby across regions: delta transport, duplicated storage and the failback egress bomb nobody budgets.
• Cross-AZ Cost Calculator — What microservices chatting across availability zones bills at $0.01/GB each direction — with the savings from placement affinity.
• Database Read Replica Calculator — Whether a read replica beats vertically scaling the primary: offloaded read cost versus the replica-hour and replication traffic.
• Database Write Capacity Calculator — DynamoDB write spend in on-demand versus provisioned mode, with the item-size multiplier that doubles silent bills.
• Cache Hit Rate Value Calculator — What each point of hit rate is worth: backend calls avoided, priced at your real per-request backend cost.
• Cache Miss Cost Calculator — The bill and latency your miss rate creates: every percent of miss at your RPS is real DB queries and real user wait.
• Queue Cost Calculator — The full price tag for queue cost: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Event Bus Cost Calculator — The full price tag for event bus cost: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Serverless vs Server Calculator — The full price tag for serverless vs server: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Container vs VM Calculator — The full price tag for container vs vm: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Kubernetes Overhead Calculator — The full price tag for kubernetes overhead: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Microservices Cost Calculator — The full price tag for microservices cost: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Monolith Migration Cost Calculator — The full price tag for monolith migration cost: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Cloud Migration Cost Calculator — The full price tag for cloud migration cost: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Lift and Shift Cost Calculator — The full price tag for lift and shift cost: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Re-Architect Cost Calculator — The full price tag for re-architect cost: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• PaaS vs IaaS Calculator — The full price tag for paas vs iaas: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• SaaS vs Build Calculator — The full price tag for saas vs build: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• Total Cost of Ownership Calculator — The full price tag for total cost of ownership: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.
• ROI of Cloud Calculator — The headline efficiency ratio for roi of cloud: what the spend earned in total, as a multiple, and normalised per year so it can fight other options on one page.
• Cloud Carbon Footprint Calculator — Activity × factor arithmetic for cloud carbon footprint: the kg CO₂e total, the offset price tag, and the scale marker (trees) that makes tonnes tangible.
• Cloud Sustainability Score Calculator — Attainment of cloud sustainability score against a target, with the absolute gap and the weighted contribution for scorecard roll-ups.
• FinOps Savings Calculator — The full price tag for finops savings: variable spend, one-off costs and an explicit contingency band, with the all-in per-unit figure quotes obscure.

Reading a Cloud & Infrastructure result

A number on its own is the weakest thing a calculator can give you, so these tools pair each output with the comparison that gives it meaning: the gap to a target, the band the value falls in, or what a realistic swing in one input does to the answer. When a figure looks wrong, that is usually the fastest place to check — re-run it with one input moved and see whether the change lines up with the formula printed above the result.
