About CloudCostKit
Practical calculators for cloud planning: egress, logs, storage, Kubernetes, and break-even analysis.
Principles
- Transparent assumptions: each tool defines what is included and excluded.
- Utility first: focus on measurable drivers and decision-ready outputs.
- Privacy-friendly: calculators run in your browser.
- Validation-oriented: every estimate should map to real billing or metrics data.
What this site is for
- Budgeting: get a directional monthly estimate quickly.
- Comparisons: compare workload shapes, tiers, and architecture options.
- Right-sizing: convert requirements into billable units.
- Validation: reconcile estimates against billing exports and metrics.
How we maintain quality
- Each page must include unique decision guidance and validation steps.
- Similar topics are split by intent so pages are not template duplicates.
- High-traffic pages are refreshed first when pricing patterns drift.
- Calculator and guide pages are maintained together for better user outcomes.
How to get accurate estimates
- Start with measurable drivers (requests/month, GB/month, hours, GB-month).
- Use effective rates first to get directionality.
- Add boundaries and multipliers (retries, fan-out, cache hit rate).
- Validate against a real week of data and update assumptions.
See Methodology and the estimation checklist.
Data and pricing sources
Calculators accept your own pricing because provider rates vary by region, tiering, discounts, and product options. For official reference, use provider pricing pages and then validate against your billing exports.
- AWS: aws.amazon.com/pricing
- Azure: azure.microsoft.com/pricing
- Google Cloud: cloud.google.com/pricing
Limitations
- Tools are simplified planning models; production bills can differ due to pricing rules.
- Incidents can shift cost drivers quickly (retries, bot spikes, backfills).
- Provider documentation remains the source of truth for procurement decisions.
