Hosting bandwidth is the amount of data transferred when visitors load pages, images, scripts, downloads, and other files. This calculator estimates monthly page views and data transfer from visitors, pages per visit, average page weight, cache or CDN savings, and a safety margin.
Estimate data transfer from visits, pages per visit, average page weight, and cache or CDN savings.
How this tool helps
Real transfer can differ because repeat visitors use browser caches, a CDN may serve most static files, bots consume traffic, video may be hosted elsewhere, and large downloads can dominate usage. Check hosting analytics after launch and optimize image formats, scripts, fonts, and cache policies.
How to use it
- Enter expected monthly visitors and pages per visit.
- Measure a representative page weight instead of guessing when possible.
- Estimate the percentage served from cache or a CDN.
- Use the recommended allowance when comparing hosting plans.
Frequently asked questions
Is bandwidth the same as storage?
No. Storage is the space occupied by website files and databases. Bandwidth is the data transferred over time.
Does a CDN reduce hosting bandwidth?
It often reduces origin transfer by serving cached files from edge locations, but billing and cache behaviour depend on the provider.
What increases page weight most?
Large images, video, web fonts, advertising scripts, page builders, trackers, and unoptimized JavaScript can add significant transfer.
