Inputs
Use realistic values from your cloud bill, contracts, and team rates. Set unused fields to zero.
Formula Used
This calculator estimates monthly cost by combining infrastructure, platform fees, operations, labor, and amortized setup effort.
| Component | Formula |
|---|---|
| Active compute hours | Requests × RuntimeSeconds ÷ 3600 |
| Provisioned compute hours | ActiveHours ÷ Utilization |
| Compute cost | ProvisionedHours × HourlyRate × Redundancy × (1 − Discount%) |
| Storage cost | (ArtifactsGB + LogsGB + OtherGB) × StorageRate |
| Network cost | EgressGB × EgressRate + IngressGB × IngressRate |
| Platform fee | PlatformFlat + InfraSubtotal × PlatformPercent% |
| Operations cost | Monitoring + Security + CI/CD + Retrieval + Backups + Support |
| Labor cost | EngineerHours × LoadedRate |
| Overhead | LaborCost × Overhead% |
| Amortized setup | (SetupHours × LoadedRate) ÷ AmortMonths |
| Monthly total | Subtotal + Subtotal × Tax% |
Tip: If you provision fixed instances, set utilization to match average load, including idle time.
How to Use This Calculator
- Enter expected requests per month and average runtime.
- Set hourly compute rate and expected utilization.

- Fill storage and data transfer based on retention and traffic.
- Include platform, tooling, and operations recurring charges.
- Add maintenance hours, loaded rates, and overhead percentage.
- Optionally amortize setup work across your planning horizon.
