Count Worker invocations, not page views.

Separate free static asset requests from executed Worker code, test the Free plan against a peak day, and estimate the Paid plan’s request and CPU charges.

Monthly traffic

Dynamic Worker invocations API, SSR, middleware, scheduled, and other executed requests. Static asset requests Static traffic invoking the Worker, % Use 100 for a global run_worker_first path. Other monthly invocations Include WebSocket upgrades and work not counted above. Peak-day multiplier Peak day divided by the average day.

Estimate

Workers usage

Billed invocations: 1,000,000/month; 9,000,000 static asset requests bypass Worker billing.
CPU time: 5,000,000 ms/month; 5 ms average across billed invocations.
Estimated Paid cost: $5.00/month; $5.00 minimum + $0.00 request overage + $0.00 CPU overage.

Free fits this traffic and CPU model.

Estimated peak: 66,667 Worker invocations/day.

What this estimate excludes

KV, D1, R2, Durable Objects, Queues, Workflows, AI, Browser Rendering, Images, and Containers have separate usage models. Add those from their current product pages instead of treating the $5 Workers minimum as the whole application bill.

Free-plan fit also depends on memory, subrequests, script size, asset count, environment variables, and other platform limits. Paid raises several limits but does not make every server workload an edge Worker.

Use Workers Analytics to get real invocation and CPU distributions. An average can hide a slow route, a traffic spike, or one scheduled job that exceeds its per-invocation CPU limit.
