Cost · plan time

Know what a change costs before you apply.

Stategraph prices a pending change while you plan it. stategraph plan prints a current‑versus‑planned monthly cost delta right under the diff — so an expensive change shows up in review, not on next month's bill.

A plan tells you what changes. Not what it costs.

terraform plan shows the resources you're adding, changing, and destroying — with no idea what any of it does to the bill. The price arrives weeks later, on an invoice, long after the review that could have caught it. Bolt-on cost tools help, but they're a separate integration and an extra step in every pipeline.

The cost is in the plan output.

Run the same stategraph plan you already run. It fetches the delta automatically and prints a Costs: block after the diff — totals as current → planned, then the per-resource breakdown.

What you get

Inline current → planned delta

Every stategraph plan (and tf mtx, and apply) ends with monthly and hourly totals as current → planned, plus the net change in priced resources.

Per-resource breakdown

The delta is attributed down to the resource: + added, - removed, ~ changed, each with the dollar amount it adds or removes from the bill.

Best-effort, never blocking

The fetch waits up to --costs-wait seconds (default 3) and never holds up your plan. Not ready yet? Re-check any time with stategraph tx costs --tx <id>.

Multi-cloud list prices

Estimates are computed from public AWS and GCP pricing, kept current so a delta tracks provider list prices — no cloud credentials required to price a plan.

Reconciles against real spend

Estimates are one half of the story. Stategraph Cost lines them up against your actual billed spend, imported from AWS, GCP, or Azure billing exports.

Available over the API

The same delta is a JSON document at GET /api/v1/tx/{tx_id}/costs — wire it into a merge gate, a Slack notice, or your own report.

Cost preview is part of the plan, not a tool beside it. The delta is computed from the very plan Stategraph is already previewing, so there is nothing to integrate and nothing extra to run. It activates once a pricing service is configured. Plan-time cost docs →
