There is no single data amount for a continuous YouTube stream through AWS Elemental MediaPackage. For a planning estimate, add the bitrates of every input rendition, then multiply the aggregate Mbps by about 0.45 for decimal GB per hour or 10.8 for decimal GB per day, before overhead and any redundant copy.
That calculation estimates traffic sent into MediaPackage, not automatically the data MediaPackage sends out or YouTube delivers to viewers. Your actual total depends on the workflow, bitrate behaviour, runtime, redundancy setting and the units shown by your monitoring or billing tools.
Identify the data leg you mean
A live workflow can have several separate network legs. An encoder sends an input stream to MediaPackage; MediaPackage can package that input into outputs when a downstream consumer requests them; and YouTube may receive an output in a workflow that routes MediaPackage content to YouTube. YouTube then handles delivery to viewers according to its own live-streaming process. The data on one leg is not a substitute for measuring another.
For the arithmetic in this guide, “MediaPackage data use” means the amount transferred from the upstream encoder or encoders into MediaPackage. If your encoder sends a 6 Mbps stream continuously for an hour, the simple estimate applies to that incoming stream. It does not tell you how many bytes MediaPackage later sends to YouTube, nor the total volume YouTube serves to every viewer.
The precise architecture matters. AWS describes a MediaPackage channel as an entry point for a content stream, while its service can package content for downstream requests. Check the AWS MediaPackage channel documentation and the AWS explanation of MediaPackage terms against the components you actually use. A diagram or configuration showing each connection is often more useful than a single assumed “stream” figure.
If you are designing the encoder stage as well as the packaging stage, the guide to creating a live streaming channel with AWS Elemental MediaLive gives broader workflow context. For a YouTube channel run from a local machine rather than a managed cloud workflow, the VLC and OBS 24/7 music stream guide covers a different set of operational choices. Neither changes the bitrate arithmetic; each helps clarify where the source and destination sit.
Add simultaneous input rendition bitrates
The calculation starts with the aggregate bitrate actually sent into MediaPackage. If there is one input rendition, use its bitrate. If multiple renditions are sent at the same time, add them together before converting to data volume.
For example, suppose an encoder sends three simultaneous inputs at 4 Mbps, 2 Mbps and 1 Mbps. Their aggregate input bitrate is 7 Mbps. Apply the hourly or daily rule to 7 Mbps, not just to the highest rendition and not to the bitrate of a single rendition chosen in isolation. If the inputs run for different periods, calculate each period separately rather than assuming all streams were active for the full day.
The phrase “aggregate input” is important in a multi-rendition setup. It refers to all concurrently transmitted input streams that cross the leg being estimated. It does not necessarily mean the total bitrate of every output format MediaPackage can create. Outputs and viewer formats belong to downstream legs and should be counted separately if you are estimating those legs.
YouTube’s current live encoder settings guidance gives recommendations that vary by codec, resolution and frame rate. Treat those as guidance for configuring a YouTube encoder, not as a measurement of MediaPackage usage. If your workflow sends a different set of inputs to MediaPackage, use the bitrates configured and observed for those inputs. A checklist on balancing bitrate and latency for a YouTube live stream can help with the encoder trade-off, but your data estimate still follows the actual aggregate bitrate.
A practical way to avoid a misleading total is to write down a small inventory before calculating: each input name, its sustained or target bitrate, whether it runs concurrently, and whether a duplicate copy is transmitted. This is especially useful when one source has separate high- and low-bitrate renditions, or when a primary and backup encoder both send content. You can then calculate from the inventory instead of relying on a single headline bitrate from a configuration screen.
Estimate GB per hour from Mbps
For a sustained bitrate, a useful decimal planning rule is:
| Aggregate input bitrate | Approximate data per hour, one copy |
|---|---|
| 1 Mbps | 0.45 GB |
| 4.2 Mbps | 1.89 GB |
| 6 Mbps | 2.7 GB |
| 10 Mbps | 4.5 GB |
The rule is GB per hour ≈ Mbps × 0.45. It comes from converting bits per second over an hour into bytes and expressing the result in decimal gigabytes. It is an arithmetic estimate, not a promise that a dashboard will show precisely that value.
For a 6 Mbps aggregate input, the calculation is 6 × 0.45, or about 2.7 decimal GB per hour for one copy. For a 7 Mbps aggregate input, it is about 3.15 GB per hour. If the aggregate bitrate changes during the hour, a single constant-rate calculation will be approximate; use a representative average bitrate or calculate separate intervals where you have more detail.
AWS’s deployment planning guide includes an illustrative conversion of 4.2 Mbps aggregate input to approximately 1.85 GB per hour, and gives approximately 3.70 GB per hour for redundant input. Those figures use a binary conversion convention, which is why they differ slightly from the decimal rule here: 4.2 × 0.45 gives about 1.89 decimal GB per hour. The AWS example is a worked conversion, not a universal usage amount or a measurement of your deployment. See AWS’s live streaming deployment planning guide for its assumptions.
When checking a calculation, label the unit convention. A decimal GB is one billion bytes; some displays use binary units such as GiB, or label a binary-sized quantity as GB. Even if both calculations begin with the same bitrate and duration, the printed number can differ because the unit definition differs. This is not evidence by itself that data is missing or that the stream has unexpectedly changed.
Estimate GB per day from Mbps
For a continuous 24-hour run, the decimal planning rule is GB per day ≈ Mbps × 10.8, again for one copy. It is the hourly estimate multiplied by 24. At 6 Mbps, that gives about 64.8 decimal GB per day. At 7 Mbps, it gives about 75.6 decimal GB per day. These amounts estimate the incoming transfer associated with the stated bitrate and runtime; they do not include a second redundant copy.
For a run that lasts less or more than a day, scale by the actual runtime. At an aggregate 6 Mbps for 12 hours, the estimate is about 32.4 GB. If it runs for 30 hours, the estimate is about 81 GB. These remain planning figures based on a sustained rate; they do not infer the schedule or the actual average bitrate from the fact that a channel is described as continuous.
A useful worksheet is to keep the inputs explicit:
| Item | Example | What to record |
|---|---|---|
| Aggregate bitrate | 6 Mbps | Sum of simultaneous input renditions |
| Runtime | 24 hours | Actual interval being planned |
| Copies transmitted | 1 | Increase the total if a duplicate is sent |
| Decimal hourly estimate | 2.7 GB | Aggregate Mbps × 0.45 |
| Decimal daily estimate | 64.8 GB | Aggregate Mbps × 10.8 |
You can use this for a devotional stream, an ambience loop or a local news channel, provided you use the bitrate and runtime for that actual workflow. For a recurring YouTube radio stream hosted from a virtual private server, the VPS guide for India explores the hosting side; do not assume that its outbound transfer is the same as the encoder-to-MediaPackage estimate here.
Account for redundant ingest copies
Some architectures transmit redundant input copies to separate ingest URLs so that a backup source is available if the active input fails. If both copies are being sent across the network, include both in the incoming transfer estimate. With two identical 6 Mbps copies, the network carries about 12 Mbps in aggregate across the two paths, giving an estimate of about 5.4 GB per hour or 129.6 GB per day in decimal units.
The comparison is straightforward when copies have equal bitrates. If the primary sends 6 Mbps and the redundant copy sends 4 Mbps, add 6 and 4 for a total of 10 Mbps of transmitted input, then apply the conversion. Do not double a total automatically if the redundant stream is configured differently or is not being transmitted during the interval you are estimating. Use what crosses the network, not just the intended failover design.
AWS’s MediaPackage guidance describes redundant inputs as a way for the service to use an active source and switch to another source on failover. Redundancy can reduce dependence on a single input path, but it may increase the amount of traffic sent to the ingest endpoints while both sources are active. A failover arrangement is therefore a reliability choice with a data-volume consequence, not a free copy from the perspective of upstream transfer.
Keep two questions separate: how much data is sent by your encoders, and how the service behaves when a source fails. The first can be estimated by adding the bitrate of every transmitted copy. The second depends on the service and configuration. Do not infer from an estimate that MediaPackage will always process both inputs as independent viewer streams, or that a backup source is necessarily carrying traffic at the same bitrate in every deployment.
Separate ingest from delivery traffic
An ingest estimate cannot stand in for MediaPackage output bytes. If MediaPackage packages content for a downstream request and your architecture routes that output to YouTube, that output leg has its own amount of data. The output can depend on the requested format, tracks, duration of requests and configuration. Measure it on the output side rather than treating the encoder’s input bitrate as a direct reading of egress.
AWS documents the CloudWatch EgressBytes metric as bytes successfully sent by MediaPackage for each request. It publishes metrics at least every minute, and an interval with no requests has no output data for that interval. For a period-specific view of MediaPackage egress, inspect that metric and sum the relevant values over the period. The AWS MediaPackage metrics documentation explains the metric and its scope. It measures output sent by MediaPackage; it does not measure the incoming encoder bytes by itself.
YouTube viewer delivery is a further distinct matter. YouTube says it automatically transcodes a live stream into multiple output formats so viewers on different devices and networks can watch. That means the incoming encoder bitrate helps estimate source transfer, but does not determine total bytes served to all viewers. Unless viewers are receiving a delivery path that actually traverses MediaPackage, their YouTube playback should not be reported as MediaPackage egress.
This distinction matters when you are comparing service bills, network usage or architecture options. Make a separate line for encoder-to-MediaPackage ingest, MediaPackage-to-downstream output where applicable, and YouTube delivery. A MediaPackage egress metric can answer a question about output bytes from that service; a bitrate-times-runtime calculation answers a planning question about incoming data. Neither one alone is a full account of every network leg.
Allow for overhead and measurement differences
Bitrate is a useful starting point, but a configured target does not guarantee a constant byte rate at every instant. Variable bitrate content can move above or below its target as the picture and audio change. Protocol and transport overhead also add traffic beyond the encoded media payload. These effects are why the conversion is best used for capacity planning and rough comparison, rather than as an exact observed total.
A quiet, mostly static image and a rapidly changing scene can behave differently when the encoder uses variable bitrate. If the encoder reports a bitrate range or an average, use the observed average over a representative period when you need a closer estimate. For a planning figure, state the assumed aggregate bitrate and mark it as an estimate. That makes the calculation reproducible and makes it clear which assumption to revisit if the actual transfer differs.
Monitoring and billing displays can also use different time windows, rounding, and unit conventions. A dashboard may report bytes, decimal GB, or a binary quantity. A short interval may not align neatly with the exact time when a stream began or ended. Compare like with like: the same leg, the same interval, the same number of copies, and the same definition of GB or GiB.
If your question is specifically about MediaPackage egress, use the output metric rather than multiplying encoder bitrate by a day. If it is about ingest transfer, use aggregate input bitrate and include redundant copies. If it is about all data used by a YouTube channel, draw the data paths first and measure each leg separately. This simple separation prevents the most common planning error: assigning viewer delivery or service output bytes to the ingest estimate.
For a channel that must continue while your own computer is off, the operational problem may be keeping a prepared video running rather than estimating a MediaPackage input path. StreamNeo removes the need to leave a personal computer broadcasting by turning an uploaded video into a continuous YouTube stream, while this bitrate calculation remains relevant to workflows that actually send inputs into MediaPackage.

FAQ
How much data is 1 Mbps for a full day?
At a sustained 1 Mbps, the decimal planning estimate is about 10.8 GB for 24 hours for one input copy. It is a bitrate-derived estimate, not a promise about a measured total; overhead and the unit convention used by a display can change the reported figure.
Do I add the bitrate of each rendition?
Yes, when the renditions are transmitted simultaneously into MediaPackage and you are estimating that ingest leg. Add their bitrates first, then apply the hourly or daily conversion. Do not include downstream output renditions unless you are separately estimating an output leg.
Does redundant input double the data?
Two identical copies transmitted at the same time approximately double the incoming transfer compared with one copy. If the copy has a different bitrate, add the two rates instead of doubling; if it is not sent during the interval, do not count it for that interval.
Does this estimate include YouTube viewers?
No. It estimates encoder-to-MediaPackage input transfer. MediaPackage output, where used, should be measured separately, and YouTube’s viewer delivery is not automatically MediaPackage egress.
