Concurrent Users Formula
Concurrent Users = (Monthly Traffic x Average Page Duration) / (30 x 24 x 60)
RAM Calculation
Total RAM = Concurrent Users x RAM per user
WordPress average RAM:
- 1 user = 30–80 MB RAM
CPU Calculation
| Concurrent Users | CPU |
|---|---|
| 1–10 | 1 vCPU |
| 10–30 | 2 vCPU |
| 30–80 | 4 vCPU |
| 80+ | 8 vCPU |
Bandwidth Calculation
Bandwidth = Visitors x Average Page Size
Example:
- 30,000 visitors
- 2 MB page size
= 60 GB / month
Hosting Plan Table
| Traffic | Concurrent | RAM | CPU | Hosting |
|---|---|---|---|---|
| 0–10K | 1–5 | 512MB–1GB | 1 vCPU | Shared |
| 10–50K | 5–20 | 1–2 GB | 2 vCPU | VPS |
| 50–200K | 20–50 | 2–8 GB | 4 vCPU | Cloud |
| 200K+ | 50+ | 8GB+ | 8 vCPU | Cloud/Dedicated |
Result Formula
Correct Capacity = Concurrent Users x Resource Consumption x Safety Buffer
