Estimate a practical hosting tier from monthly traffic, site type and the amount of dynamic or logged-in activity.
Enter your values and calculate.
This is a planning estimate based on the values you enter. Real WordPress environments can be affected by disk speed, database size, cache behavior, provider limits, plugin architecture, active traffic and third-party services. Verify the production environment before making a live change.
A heavily cached blog can serve large visitor numbers efficiently, while a much smaller WooCommerce or membership site may require significantly more origin CPU and database capacity because more requests bypass full-page cache.
Use the calculator as a planning aid, then validate the result against the actual WordPress installation, hosting account and production traffic. These notes explain the technical assumptions behind the result and the checks I would make before acting on it.
Two sites with the same monthly visits can need very different resources. A cached article page may use little PHP, while checkout, search, account pages, LMS lessons and logged-in dashboards can bypass full-page cache and create much more database and PHP work.
WooCommerce, memberships and LMS platforms create sessions, carts, scheduled actions and frequent writes. These workloads need enough PHP concurrency, database headroom and object caching to remain stable during busy periods.
Sizing a server at its normal peak leaves no room for traffic spikes, plugin jobs, backups or imports. A practical migration target should include spare CPU, memory and disk capacity so routine maintenance does not compete with visitors.
The calculator is a starting point. After migration, use real monitoring for CPU, RAM, database load, slow queries, PHP errors, cache hit ratio and response times to decide whether the environment should be tuned or resized.
No. It is an estimate based on the inputs available in a browser. Production WordPress sites can have custom code, unusual server limits, third-party integrations and traffic patterns that change the real requirement.
The calculator runs in your browser. The page does not need an account or a database to calculate the result. Avoid pasting passwords, API keys or private customer information into any planning field.
Use a manual review when the site generates revenue, has active users, contains a large database, uses memberships or subscriptions, has custom integrations, or cannot tolerate an extended rollback window.
The useful part of a planning tool is not the number by itself. It is understanding which assumptions produced the result, which production conditions can change it, and what should be checked before you act. Use this tool as part of a wider migration or infrastructure review rather than as an automatic go/no-go decision.
Hosting decisions depend on CPU time, memory, disk I/O, PHP workers, database behavior, cache hit rate, file count and operational limits. A single storage or memory value should be treated as one part of the environment.
Backups, archives, temporary extraction directories and database dumps can briefly require far more disk space than the live site itself. Planning without temporary headroom is a common reason migrations fail part-way through.
Shared and managed platforms can impose inode, process, upload, execution-time, cron, database or outbound-transfer limits. Compare the estimate with the real plan limits before committing to a production move.
Treat it as a planning starting point with operational headroom. Real requirements depend on workload and provider limits.
Migration archives, extraction copies and backups may coexist with the live site. That can temporarily double or triple storage demand.
No. Dynamic requests, PHP workers, database load, admin activity, WooCommerce and cacheability can matter more than raw visitor count.
