Bitrate Calculator

Convert and calculate bitrate, file size, duration, and streaming data usage using consistent bits/bytes rules and clear unit settings.

Bitrate, Size, Time, and Data Consumption Estimator

Pick units, enter what you know, and calculate the missing value with helpful conversions and practical readouts.

This calculates average bitrate from a file’s total size and its duration. Overhead can represent container overhead, extra tracks, or non-content bytes included in the file.
Estimate file size from bitrate and duration. If you want “video only” size, subtract your audio bitrate from the total first, or set overhead lower.
Solve for duration from file size and bitrate. Useful for “How long can I record?” or “How long will this stream last?” type questions.
Estimate how much data a stream uses over time. This is an average estimate based on bitrate; adaptive streaming and network conditions can change real usage.
