Terraform Cost Estimator
Paste terraform show -json output (or an Infracost breakdown) and see every AWS and GCP resource the change creates, updates or destroys priced line by line, with cheaper machine types and regions for each. The pricing engine runs in your browser; the plan is never uploaded.
Your plan never leaves this browser: the pricing engine runs in this tab, and secrets Terraform marks sensitive are dropped before anything is read.
Frequently asked questions
How do I estimate the cost of a Terraform plan?
Run terraform plan -out tfplan, then terraform show -json tfplan, and paste the output here. Each resource the plan creates, changes or destroys is priced from its own arguments: an instance type, a volume size, a node count. A destroy is a saving, and an update prices only the difference.
Is my plan uploaded anywhere?
No. The pricing engine runs in this browser tab. Values Terraform marks sensitive are dropped before anything is read, and nothing is sent to a server.
Why does it say "at least" instead of a total?
Some charges depend on traffic a plan cannot state, such as GB through a NAT gateway or requests to a load balancer, and some resource types are not priced yet. Those are listed by name rather than counted as zero, so the figure is a floor you can trust rather than a total you cannot.
Can I use it with Infracost?
Yes. Paste the output of infracost breakdown --format json. Resources whose price is fully described by their components are re-priced by this engine, and the rest keep Infracost's own figure, marked as such.
Are these the prices I will actually pay?
They are public list prices. Negotiated discounts, Savings Plans, Reserved Instances and committed use discounts all change the answer, which is what the Finitizer product prices a plan at: your own rates, per account.
