Cloud Cost Waste Estimator
Cloud waste is rarely one big mistake. It is a dozen small ones nobody owns. This estimates how much of your bill is recoverable and points at the categories worth investigating first.
How much of a typical cloud bill is wasted?
For small and mid-size companies without a dedicated platform team, a meaningful share of the bill is usually recoverable — most often from non-production environments running around the clock, oversized instances chosen during a launch and never revisited, and storage that accumulates because nobody set a lifecycle policy. The recoverable share is not a single industry number: it depends on how many environments you run, how variable your traffic is, and how long it has been since anyone audited the account.
Methodology
How this is calculated
Published in full, so you can disagree with it. A tool that hides its model is a lead form.
- Idle waste = your idle estimate × 80% of the bill share it represents. Rightsizing rarely recovers the whole amount because some headroom is needed.
- Storage waste = storage share × 22%, covering lifecycle policies, orphaned volumes and old snapshots.
- Non-production waste = (environments − 1) × 12% of the bill, × 62% — the proportion of a week that falls outside business hours.
- Elasticity opportunity = a factor from your traffic pattern: 3% for steady workloads, 18% for business-hours workloads, 12% spiky, 15% seasonal.
- The total is capped at 60% of the bill. Any estimator returning more than that is guessing.
Assumptions and limits
- This is a directional estimate from self-reported figures, not an audit. A real audit reads your billing data and tagging.
- Reserved instances, savings plans and committed-use discounts are not modelled and can change the picture significantly.
- Engineering time to recover the waste is not included. Below roughly $1,000/month of spend, that time usually costs more than the saving.
- Data-transfer costs — a common surprise on the bill — are not separately modelled.
Worked examples
A $4,000/month bill with 3 environments
Non-production out-of-hours shutdown alone typically accounts for a substantial share, and it is the easiest change to make safely.
A $600/month bill
The tool will tell you not to bother. Engineering time to optimise would exceed the recovery.
