Real-time calculation
Right-size your plan
Everything you need to master bandwidth planning
Precision estimates that prevent overage surprises.
Visitor Traffic Based
Calculate bandwidth using monthly unique visitors, average pages per visit, and page size. Most accurate method for real-world usage.
Asset Request Factor
Include images, CSS, JS, and font files — each page typically loads 50-100 assets that consume bandwidth.
Caching & Repeat Visitors
Account for browser caching — repeat visitors download fewer assets, reducing effective bandwidth by 30-60%.
Peak Traffic Multiplier
Estimate burst bandwidth requirements for traffic spikes, sales events, or viral content moments.
Hosting Plan Matching
See which hosting tier (Shared, VPS, Dedicated) fits your bandwidth needs across popular providers.
Video & Media Streaming
Specialized calculation for video-heavy sites — input video bitrate, average watch time, and concurrent viewers.
