Enter the costs you can verify rather than treating the defaults as a recommended architecture. The useful output is the separation between provider charges and the human work needed to keep the service healthy.
What the total includes
Infrastructure covers server instances, storage or database services, backups, and bandwidth. Platform services cover monitoring, logs, and other recurring tools. Operations multiplies estimated monthly maintenance hours by an internal or contracted hourly cost.
How to use the estimate
Start with a provider’s current price for the region and address type you will actually use. Add stateful services and backup retention, then estimate routine patching, release, alert, and restore work. Test a production build and measured workload before changing the instance count.
What remains outside the model
The calculator does not infer tax, exchange rates, reserved pricing, support plans, incident losses, migration work, domain registration, email, observability ingestion, or database transfer. Add recurring items under the closest editable category and document one-time costs separately.
