Streaming Bitrate Calculator
Use this free streaming bitrate calculator to estimate megabytes and gigabytes used by a bitrate over a chosen duration.
Inputs explainedResult checksExample valuesRuns in your browser
Formula steps
- Convert bitrate to megabits per second.
- Multiply by total seconds and number of streams.
- Divide megabits by 8 to estimate megabytes, then by 1,000 for gigabytes.

Frequently asked questions
Plain-language answers about when to use the tool, what it does with your inputs, what to double-check, and how privacy works.
When should I use the Streaming Bitrate Calculator?
Use it when your task matches one of these common needs: Estimate data use before streaming on a limited connection. Plan recording storage for a long event. It works best when you already know the text, code, URL, mode, format, or technical setting the page asks for.
What is the Streaming Bitrate Calculator doing with my inputs?
In plain language: Mbps = Kbps / 1,000 when needed. Total seconds = (hours * 3,600 + minutes * 60) * streams. Megabits = Mbps * total seconds. MB = megabits / 8. GB = MB / 1,000. The examples on the page are there so you can compare your inputs with a filled-out example before copying the answer.
What do the main Streaming Bitrate Calculator inputs mean?
Bitrate: The video or audio data rate from the encoder, export setting, platform recommendation, or stream dashboard. Bitrate unit: Choose Kbps for small audio rates and Mbps for most video streams or recordings. Duration: How long the stream, upload, recording, lesson, event, or camera feed runs. Streams: How many streams, cameras, files, or simultaneous feeds use the same bitrate and duration.
How should I read the Streaming Bitrate Calculator answer?
Read the output next to your original input. If the tool changes format, units, encoding, spacing, or capitalization, compare a small sample before copying the whole result into another app.
What should I double-check before trusting the answer?
Variable bitrate, adaptive streaming, audio tracks, subtitles, chat, metadata, retransmits, previews, and platform processing can make real data use different. Also check the selected mode, input format, encoding, and whether the text includes private keys, passwords, or sensitive data.
Is bitrate the same as resolution?
No. Resolution is pixel size, such as 1920 x 1080. Bitrate is how much data per second the video or audio uses.
Should I enter video bitrate or audio bitrate?
Enter the total bitrate you want to estimate. For a video file or livestream, add video and audio bitrate together if your export or platform shows them separately.
Does this tell me the upload speed I need?
It estimates data use from bitrate and time. For live streaming, your upload speed should usually be comfortably higher than the stream bitrate because overhead, Wi-Fi, and congestion can cause drops.
Why are MB and GB decimal estimates?
The calculator uses decimal units: 1 GB = 1,000 MB. Some storage apps show binary GiB instead, so a saved file may look slightly different in your operating system.
Can I use this for multiple cameras?
Yes. Use the Streams field for cameras or feeds that share the same bitrate and runtime. If each camera uses a different bitrate, calculate each group separately and add the results.
Why does my actual file size differ?
Many apps use variable bitrate, which changes data rate scene by scene. Audio, subtitles, thumbnails, and container overhead can also change final size.
Does the site save what I enter?
No. The tool runs in your browser tab. Your recent answers stay only on the page while you use it, and they are not sent to a server.
