Cloud waste calculator
Add the instance types in your fleet, how many of each you run, and the usage pattern that actually fits the workload — this estimates the monthly cost at that pattern and the idle burn you're paying if those same instances are left running around the clock instead. List price, cheapest listed region, no signup required.
This is a list-price estimate. The free Idle Audit measures your real CloudWatch/Monitoring metrics.
Run a free idle auditThis calculator estimates what your fleet is actually costing at the usage pattern you set for each row, and weighs that against what the same instances would cost running 24/7 with no schedule at all. Add a row per instance type, pick a count and a pattern, and both totals update as you go — nothing here is saved or sent anywhere.
The numbers come from a public snapshot of on-demand list prices for AWS and Google Cloud, not your actual bill — there's no account involved, and nothing here reads your cloud usage or billing history. It's a quick way to size the problem before you commit to anything. For the real figure, the free idle audit measures your infrastructure directly and reports what's genuinely sitting idle, instead of estimating from a list price.
Prices are on-demand list price and exclude storage, network, data transfer, and any negotiated or volume discounts. Actual bills vary by usage and account-level pricing. Prices as of 2026-07-20.
