Estimate yourcloud costs.

Live AWS, GCP, and Azure pricing - side by side, with the per-category winners and the line items most calculators conveniently forget. No signup. Runs in your browser.

Why this calculator

Built by FinOps practitioners - for directional decisions a CFO can actually defend.

Live pricing

AWS via Vantage, Azure via the Retail Prices API, GCP via the Cloud Billing Catalog. Per-provider live/est badges so you know what's authoritative.

Per-category winners

Headline totals hide the real picture. We show which provider wins each line item - compute, storage, egress - and by how much.

Hidden-cost callouts

NAT gateways, partition scanning, multi-AZ, idle notebooks, support tier - the costs most calculators omit and most bills surface anyway.

Reservation framing

1-year and 3-year commitment savings on top of every estimate, plus an annual + 3-year on-demand TCO.

How it works

  1. 01

    Pick an architecture

    Web app, data pipeline, API backend, or ML training. Each preset loads the right mix of cloud services with sensible defaults.

  2. 02

    Configure your parameters

    Instance size, count, storage, egress, request volume. The form adapts to the architecture - ML shows GPU options, API backend shows request volume.

  3. 03

    Read the insights, not just the totals

    Live per-provider totals plus annual TCO, per-category winners, 1y/3y reservation savings, and the architecture-specific costs we deliberately don't model - so you know what to verify before signing off.
