About the Storage & Bandwidth Calculator

The Storage & Bandwidth Calculator estimates monthly storage and bandwidth needs across six use cases: Website, Video Streaming, CCTV/IP Camera, Cloud Storage, CDN, and Internet Browsing. Enter details like visitor counts, video quality, camera resolution and retention days, user counts, or origin content size, and get an instant breakdown with a recommended plan tier for that use case.

It’s built for site owners, IT planners, security installers, and anyone budgeting data usage before committing to a hosting plan, NAS system, or CDN service. Once you know your numbers, the Domain Age Checker and SSL Checker are useful for auditing the domain and security setup tied to your website or CDN.

The BigToolSite Team tested every calculation mode — from CCTV codec efficiency to CDN cache hit ratios — to confirm the formulas produce realistic, industry-aligned storage and bandwidth estimates for each use case.

How to Use the Storage & Bandwidth Calculator

Select a calculation mode: Website, Video Streaming, CCTV/IP Camera, Cloud Storage, CDN, or Internet Browsing.
Fill in the relevant fields for that mode, such as monthly visitors, video quality, camera count and retention days, or number of users.
Click Calculate Requirements to see your storage and bandwidth breakdown along with a recommended plan tier.
Use Copy Results, Export CSV, or Export Excel to save your calculations for reference or sharing.

Example Usage

Mode: Website — 10,000 monthly visitors, 3 page views each, 1,500 KB average page size

Output: 30,000 total page views, roughly 43 GB monthly bandwidth (with a 20% safety margin).

Mode: CCTV/IP Camera — 4 cameras, 1080p, 15 FPS, H.264, 30-day retention, 24-hour recording

Output: Estimated monthly storage in the hundreds of GB, plus upload bandwidth based on camera count and bitrate.

Frequently Asked Questions

The calculations provide solid baseline estimates using industry-standard bitrates and page sizes for each use case, but actual usage can vary based on caching, compression, and content type, so treat the results as a starting point.

H.265/HEVC uses roughly half the bitrate of H.264 at similar quality, so switching codecs can cut your storage requirements significantly for the same camera setup.

It’s the percentage of requests served directly from the CDN’s cache instead of your origin server, and a higher ratio means less bandwidth load on your origin.

Yes, each of the six modes — Website, Video Streaming, CCTV/IP Camera, Cloud Storage, CDN, and Internet Browsing — has its own dedicated fields and calculation logic for that specific use case.
