When to use this calculator
Estimate video or audio streaming data from an average bitrate and viewing time. Use a bitrate including audio and any overhead you want counted; adaptive bitrate changes actual usage.

PUTTING IT INTO PRACTICE
Streaming Data Usage: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Combined average stream bitrate (Mbps) | 5 |
| Hours streamed | 2 |
| Result | 4.5 GB |
- Check the input labels and enter the example values above.
- Apply the relationship: Decimal GB = bitrate × hours × 3600/8/1000.
- The result is 4.5 GB, rounded for display.
How to interpret your result
Use a bitrate including audio and any overhead you want counted; adaptive bitrate changes actual usage.
Uncompressed pixel and PCM estimates use a predictable data layout. Compressed media sizes depend on codec and content. Average encoded bitrate can estimate file size but does not by itself establish quality.
Frequently asked questions
Will an uncompressed image estimate match a JPEG file?
Usually not. JPEG uses compression, so its final size depends on the image and encoding settings.
When is the streaming data usage calculator useful?
Estimate video or audio streaming data from an average bitrate and viewing time. Use a bitrate including audio and any overhead you want counted; adaptive bitrate changes actual usage.
How do I use the streaming data usage calculator?
Enter combined average stream bitrate (mbps), hours streamed. The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Decimal GB = bitrate × hours × 3600/8/1000.
What should I check before using the result?
Use a bitrate including audio and any overhead you want counted; adaptive bitrate changes actual usage.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
