A continuous YouTube livestream’s estimated data use can be calculated from its configured encoder bitrate and the hours it runs. For a steady stream, multiply bitrate in Mbps by 0.45 for decimal GB per hour, or by 324 for decimal GB over 30 days at 24 hours a day.
That arithmetic estimates the stream’s outbound volume; it is not a Linode-published estimate or a statement of the transfer included with your account. It also excludes protocol overhead, other server egress and any independently sent backup feed. Use it as a planning figure, then compare it with the current transfer pool and measured usage in your account.
Separate bitrate from monthly transfer
People often use “bandwidth” to mean two different things. An encoder’s bitrate is a rate: how many bits it sends each second. A provider’s monthly transfer allowance is a volume accumulated over a billing period. A 6 Mbps stream is not using 6 megabytes each second; Mbps means megabits per second, and eight bits make one byte.
This distinction matters when you are deciding whether a continuous stream fits a cloud account’s transfer allowance. Network capacity concerns whether the connection can carry the stream at a given moment. Monthly transfer concerns how much data travels out over time. The calculation below answers the second question for a steady configured bitrate, not whether a connection is fast or reliable enough.
For a stream sent from a Linode instance to YouTube, the outbound leg from that instance is the traffic relevant to its metered outbound transfer. If the instance is only encoding and sending the feed, audience playback is served by YouTube rather than by that instance. If you also serve files or video directly to viewers from the same account, that is separate outbound traffic and belongs in the broader account estimate.
Use the hourly GB formula
Start with the bitrate configured in your encoder, expressed in megabits per second. For decimal gigabytes, the conversion is:
Mbps × 1,000,000 bits/second × 3,600 seconds/hour ÷ 8 bits/byte ÷ 1,000,000,000 bytes/GB
The factors reduce to a convenient planning formula:
decimal GB per hour ≈ bitrate in Mbps × 0.45
For example, a steady 6 Mbps feed produces an estimate of 2.7 decimal GB in an hour: 6 × 0.45. This is a conversion from rate to volume using elapsed time. It does not add any traffic beyond the configured video bitrate, and it is not an observed measurement from a particular Linode account.
Use the configured bitrate rather than assuming a recommendation is what your encoder sends. YouTube’s encoder settings guidance gives recommendations that depend on codec, resolution and frame rate. Its table, for example, lists 14 Mbps for H.264 at 1080p/30 fps and 17 Mbps for H.264 at 1080p/60 fps. Those are recommended settings, not a measurement of your actual stream. Check the encoder profile you are using and substitute its configured bitrate in the formula.
The stream’s bitrate may not be perfectly steady in every setup. A variable bitrate can rise or fall with the picture, while a constant bitrate configuration aims to hold near a target rate. The simple formula uses the configured steady rate as its input, so treat the answer as an estimate when actual output varies. To keep the estimate tied to your setup, note the resolution, frame rate, codec and encoder bitrate alongside it.
Calculate a 30-day continuous stream
A 30-day period contains 720 hours if the stream runs for all 24 hours on every day. Multiply the hourly result by 720. Combining that with the formula above gives:
decimal GB for 30 days ≈ bitrate in Mbps × 324
In decimal terabytes, the equivalent is:
decimal TB for 30 days ≈ bitrate in Mbps × 0.324
At 6 Mbps, the estimate is 6 × 324, or 1,944 decimal GB in 30 days. That is 1.944 decimal TB. The result assumes a continuous, steady 6 Mbps feed for the entire period. It is a calculation from the input rate and duration, not a forecast of the exact amount Linode will meter or bill.
If the channel runs fewer hours, calculate from its scheduled hours rather than using the full-month shortcut. One way to do that is to use the hourly formula and multiply by the number of hours actually streamed in the billing period. A schedule that pauses overnight will use less volume than a 24/7 schedule at the same bitrate; a stream that restarts late or stays live through a longer billing period will have different total hours.
| Configured bitrate | Decimal GB per hour | Decimal GB in 30 days, continuously | Decimal TB in 30 days |
|---|---|---|---|
| 6 Mbps | 2.7 | 1,944 | 1.944 |
| 8 Mbps | 3.6 | 2,592 | 2.592 |
| 14 Mbps | 6.3 | 4,536 | 4.536 |
| 17 Mbps | 7.65 | 5,508 | 5.508 |
The 8 Mbps, 14 Mbps and 17 Mbps rows are arithmetic examples using the bitrate values discussed above; the table does not say that each value is appropriate for every channel. Choose based on your codec and picture requirements, then use the encoder’s actual setting. If you are deciding whether your video file and settings are suitable for a playlist, the H.264 conversion guide can help with the media side of that decision, but it does not change the transfer calculation.
Understand decimal GB and TB units
The formulas use decimal units. One decimal gigabyte is 1,000,000,000 bytes, and one decimal terabyte is 1,000 decimal gigabytes. That is why 1,944 GB converts to 1.944 TB in the example. The decimal conventions make the multipliers in the formula straightforward and are the units used in the table.
Some software displays binary units, often labelled GiB or TiB. A gibibyte is based on powers of 1,024 rather than 1,000, so the same byte count appears as a different numeric value when shown in GiB. Do not compare a decimal estimate directly with a binary-labelled display as if the numbers were identical. First check the unit label and, if needed, compare the underlying bytes or convert using the correct unit convention.
The unit choice does not mean one result includes more traffic than another. It is a difference in how the same quantity of bytes is named and displayed. If the Linode Cloud Manager or a local monitoring tool reports a value, confirm whether its label is GB, GiB or another unit before deciding that it disagrees with your spreadsheet.
Add overhead and other server egress
The bitrate formula calculates payload volume from the configured rate and time. It does not add protocol overhead or operational traffic. Network protocols and the way a particular stream is delivered can mean actual metered transfer differs from this simple estimate. For this reason, do not treat the calculated figure as a guaranteed ceiling, an invoice prediction or a complete account total.
Keep separate any other outbound traffic generated by the server or services sharing the account. For instance, a website, downloads, backups sent elsewhere or an administrative transfer could add egress in the same billing period. The size of that addition depends on what you actually send; there is no single overhead factor in this formula that captures all such traffic. Measure it or estimate it from its own workload rather than multiplying the livestream calculation by an invented allowance.
A separately transmitted backup feed also needs its own calculation. If a second encoder independently sends another 6 Mbps feed to YouTube, that is another stream’s outbound volume; calculate it separately and add it to the first stream’s estimate. A local recording kept on the instance is not itself outbound traffic at the time it is written, though moving that recording off the instance later creates its own transfer. The direction and timing of traffic matter.
If you operate a channel from a spare PC rather than an instance, the same rate-to-volume arithmetic still helps with the amount of data sent over the connection, but the billing comparison is different. A spare-PC radio stream guide discusses a different operating arrangement. For the Linode question, keep the focus on what leaves the instance and what else shares the account pool.
Compare the estimate with your transfer pool
Linode transfer allowances and usage need to be checked against the account’s current details. Linode staff explain that monthly transfer allowances contribute to an account pool, with public outbound traffic counted and inbound traffic free; private-network traffic is treated separately in that explanation. Review the Linode transfer-pool explanation and your Cloud Manager account rather than relying on an old plan figure copied into a guide.
The practical comparison is not simply “stream estimate versus one instance’s advertised allowance”. First estimate the stream’s outbound volume for the actual billing-period hours. Then add the other metered outbound use that shares the account pool. Compare that total with the pool shown for your account. If a service is created or removed partway through a period, account for any prorating described in the provider’s current terms. The allowance and possible overage treatment may depend on account, plan and region, so check current billing documentation before forecasting a charge.
| What to compare | What to enter or check | Why it matters |
|---|---|---|
| Stream volume | Configured bitrate and streamed hours | Produces the estimated outbound amount for this feed |
| Separate feeds | Each independently sent backup or additional stream | Adds another outbound stream’s volume |
| Other egress | Websites, file delivery, backups or other public outbound traffic | These can draw on the same account pool |
| Account allowance | Current pool shown in Cloud Manager | The actual available allowance is account-specific |
| Region and billing details | Current provider billing documentation | Terms and any overage rate can vary; verify before estimating cost |
Avoid inserting a historical allowance or a community-reported price into this comparison as though it were a current quote. A Linode community discussion of transfer between locations may help clarify traffic categories, but your current account view and provider billing pages are the right sources for your own allowance and terms. This calculation does not determine your bill; it gives you a stream estimate to put beside the account’s current figures.
Recheck usage against actual stream settings
Before relying on the estimate, read the configured bitrate from the encoder or streaming workflow. Do not substitute a recommendation for a setting you have not confirmed. YouTube’s live encoder recommendations vary by codec, resolution and frame rate; its streaming tips also say to leave room for upload capacity. That headroom is connection-planning guidance, not a 20 per cent multiplier for the transfer formula.
For an RTMP/RTMPS setup, YouTube’s guidance covers CBR encoding and recommends a two-second keyframe interval, not over four seconds, and RTMPS. Those are stream configuration recommendations, not extra terms in the monthly data conversion. Make sure the selected codec matches the bitrate recommendation you are consulting, and avoid treating a YouTube ingest setting as evidence of what Linode has actually recorded as outbound transfer.
You can make a small planning worksheet with columns for date range, hours live, configured bitrate, estimated decimal GB, backup-feed volume and other account egress. Recalculate when a scheduled stream changes duration or you change resolution, frame rate or bitrate. For a non-continuous schedule, multiply the hourly estimate by the hours in that period; for a different-length month, use actual hours rather than assuming 720.
Then compare the estimate with observed account usage after the stream has run. If the account’s metered outbound total is higher, investigate other services, a backup feed, changed settings, protocol overhead and the display unit before assuming the formula is wrong. YouTube Live Control Room’s stream status can help you check ingest health, but it does not replace the provider’s transfer records. A stream-key settings guide may be useful if you are checking the YouTube connection details in OBS; keep security practices in mind when handling a stream key.
For a channel whose main concern is keeping a home computer switched on and recovering a dropped broadcast, the transfer arithmetic is only one part of the operating decision. StreamNeo can remove that particular always-on-computer task by taking an uploaded video and running it as a YouTube stream, while you still need to choose suitable media settings and check your own channel and account requirements.

FAQ
How much Linode transfer does a 6 Mbps 24/7 stream use?
At a steady 6 Mbps, the calculation is about 2.7 decimal GB per hour. Over 30 continuous days, it is about 1,944 decimal GB, or 1.944 decimal TB. These are conversion estimates and exclude overhead and other outbound traffic.
Does YouTube’s recommended bitrate determine my actual usage?
No. A recommendation is a setting guide based on codec, resolution and frame rate, not a measurement of your encoder’s average bitrate. Use the bitrate actually configured for your stream in the formula, then compare with measured account usage.
Does the estimate include Linode’s transfer allowance?
No. It estimates one stream’s volume from bitrate and time; it is not a Linode-published estimate and does not establish your included transfer or bill. Check the current pool in Cloud Manager, add other metered outbound traffic and consult current provider billing terms for your account and region.
Does audience playback count against the Linode stream estimate?
If the Linode is only sending the feed to YouTube, YouTube serves the audience playback, so that viewing traffic is not sent from the Linode by this setup. Any separate service on your account that delivers media or files to viewers creates its own outbound traffic and should be accounted for separately.
