About CloudCostKit
Fast calculators for cloud planning—egress, logs, storage, Kubernetes, and pricing break-even.
Principles
- Transparent assumptions: each tool explains what it does (and does not) include.
- Simple by default: planning estimates first, with configurable inputs.
- Privacy-friendly: calculators run in your browser.
What this site is for
- Budgeting: get a directional monthly estimate quickly.
- Comparisons: compare workload shapes, tiers, and architecture options.
- Right-sizing: turn requirements (RPS, payload, retention, requests/limits) into billable units.
- Validation: build an estimate you can reconcile against billing exports and metrics.
How to get accurate estimates
- Start with measurable drivers (requests/month, GB/month, hours, GB-month stored).
- Use an effective rate first (blended $/GB or $/1M) to get directionality.
- Add boundaries and multipliers (retries, fan-out, cache hit rate).
- Validate against a real week of data and adjust assumptions.
See Methodology and the estimation checklist.
Data and pricing sources
Most calculators accept your own pricing inputs because provider prices vary by region, tiering, discounts, and product options. For official sources, start with provider pricing pages and then validate against billing exports.
- AWS: aws.amazon.com/pricing
- Azure: azure.microsoft.com/pricing
- Google Cloud: cloud.google.com/pricing
Limitations
- Tools are simplified planning models; bills can differ due to tiering, rounding, and product-specific rules.
- Incidents often change drivers (retries/timeouts, bot traffic, backfills), which can dominate monthly totals.
- Provider documentation is the source of truth. Use these tools to build and validate your model, not to replace docs.
