We built Idlefy to answer one question: how much is idle compute actually costing you? Until now, the honest answer meant opening Cost Explorer, exporting a CSV, and doing the math yourself. Today we’re shipping three free surfaces that answer it in under a minute — no signup, no credit card.

Cloud waste calculator

The cloud waste calculator takes the instance types in your fleet, how many of each you run, and the usage pattern that actually fits the workload — dev box, staging, batch job. It estimates the monthly cost at that pattern next to the cost of leaving the same instances running 24/7. For most dev and staging fleets, the gap is the whole point: you’re paying for hours nobody uses.

Schedule savings calculator

The schedule savings calculator flips the question around. Pick one instance type and region, set the hours per week it actually needs to run, and see the monthly cost on that schedule versus around-the-clock. It’s the fastest way to sanity-check a single instance before you commit to a schedule — or before you provision anything at all.

Instance idle costs

Behind both calculators is a pricing dataset we’re publishing directly: cloud instance idle costs covers 117 AWS and GCP instance types — including GPU boxes like g4dn.xlarge, where idle time gets expensive fastest — each priced at its cheapest listed region, both running 24/7 and scheduled off outside work hours. Browse by provider, or jump straight to the type you’re running today — m5.xlarge, n1-standard-4, whatever’s in your fleet.

All three pull from the same list-price snapshot, regularly refreshed. None of them ask for an account. If the numbers make you wince, that’s the same feeling that started Idlefy in the first place — the fix is the same one line: stop paying for compute nobody’s using.
