For a continuous YouTube live stream, estimate VPS egress by multiplying the stream’s outgoing bitrate by the seconds it runs, then converting bits to bytes. At a steady 1 Mbps, that is about 324 decimal GB in 30 days, before protocol overhead, retransmissions or differences in how your provider meters traffic.
This is an estimate of traffic sent from the VPS to YouTube, not an exact provider bill. Use the bitrate your encoder actually sends and the real runtime; then compare the result with your provider’s allowance, unit and usage dashboard.
What VPS egress means for a continuous stream
Egress is data leaving your VPS. In this case, the relevant transfer is the live video and audio sent from the VPS to YouTube’s ingest service. It is separate from viewer playback: YouTube transcodes an incoming live stream into formats for viewers, so your VPS’s ingest traffic is not multiplied by your audience size. You can check YouTube’s live encoder settings and recommendations when choosing the configured stream bitrate.
A useful way to think about the path is: your encoder sends one outgoing stream to YouTube, and YouTube distributes viewing formats from there. If your channel has many viewers, that may matter to YouTube’s delivery systems, but it does not mean your VPS must send a separate copy to each viewer. For this calculation, focus on the outgoing stream bitrate and how long it is actually online.
The word “bandwidth” is often used for two different things. It can mean the rate of a connection, such as whether a network can carry a stream at a given moment, or the volume of transferred data accumulated over a billing period. This article estimates the second: monthly outbound transfer. A connection with adequate rate can still use a large monthly allowance if it runs all day, every day.
That distinction matters when you compare a VPS with a home computer, a remote OBS setup, or another way to run a channel. A machine that can push the stream without interruption may still have an outbound-transfer allowance or metering rule to consider. If you are assessing the operating model as well as transfer, the remote OBS setup guide covers the separate question of keeping a streaming machine available.
Use bitrate and runtime in a formula
For decimal gigabytes, use:
decimal GB = bitrate in Mbps × seconds streamed ÷ 8 ÷ 1,000
The conversion works because Mbps means megabits per second. Multiply by seconds to get megabits, divide by eight to convert bits to bytes, then divide by 1,000 to express megabytes as decimal gigabytes. Equivalently, for a continuous stream running for a 30-day month, each sustained Mbps works out to about 324 decimal GB.
For example, a 4 Mbps stream running continuously for 30 days is 4 × 2,592,000 ÷ 8 ÷ 1,000 = 1,296 decimal GB. A 10 Mbps stream under the same assumption is 3,240 decimal GB, or 3.24 decimal TB. Those totals are calculated from bitrate and runtime; they are not figures quoted by YouTube or a VPS provider.
Use seconds, not a rounded guess about “a month”, if you want the estimate to reflect your schedule. Thirty days contains 2,592,000 seconds. For a different number of days, use days × 24 × 60 × 60; for partial days, include the actual hours and minutes. If your stream pauses for planned maintenance or goes offline, subtract that time rather than assuming continuous operation.
The formula assumes a fixed outgoing bitrate throughout the period. If your encoder uses variable bitrate, a configured maximum is not necessarily the amount it sends on average. Use a representative measured average when you have one, or total actual outbound bytes from monitoring. The YouTube settings article for a 24/7 Telugu news playlist can help you identify the encoder settings that should feed into your estimate.
Work through a 1 Mbps, 30-day example
Start with a sustained outgoing bitrate of 1 Mbps and a full 30-day runtime. The calculation is 1 × 2,592,000 seconds ÷ 8 ÷ 1,000, which gives 324 decimal GB. This is the baseline: if the bitrate doubles while runtime stays the same, the estimated payload doubles; if runtime is halved while bitrate stays the same, it halves.
Here is the conversion step in more familiar units. One Mbps sends 1,000,000 bits each second. Over 30 days, that amounts to 2,592,000,000,000 bits. Divide by eight to get 324,000,000,000 bytes, then divide by 1,000,000,000 bytes per decimal GB to get 324 GB.
The result is best read as “about 324 decimal GB of stream payload under these assumptions”. It is not a prediction that a provider dashboard will show exactly 324 GB. A provider may count additional traffic, display binary units, round at reporting intervals, or apply a different accounting scope. Those differences are discussed below, and they are why a formula is a planning aid rather than a bill calculator.
You can use this baseline to check a rough allowance before setting up a channel. If an offer lists an outbound allowance in GB, compare it on the same decimal basis where possible; if it uses GiB, convert units before deciding how much room remains. Also include other services sharing that allowance, such as file downloads, updates or a second stream. An allowance that looks adequate for the stream alone can be consumed by other outbound traffic too.
A continuous devotional audio-and-video loop at a lower bitrate may use less transfer than a high-motion news or product stream, but do not choose a bitrate only to fit a transfer allowance. Image quality, movement, frame rate and audio all affect what the channel needs. YouTube recommends testing with audio and movement representative of the actual stream and checking stream health; if your chosen setting cannot be sustained, its guidance recommends lowering the resolution. See YouTube’s live streaming troubleshooting guidance when a test shows insufficient bandwidth.
Compare YouTube bitrate examples
YouTube’s H.264 recommendations provide useful reference points, but they are not a universal bitrate table for every codec or content type. Use the row matching your encoder’s codec, resolution and frame rate, then substitute its bitrate into the formula. YouTube lists AV1 and H.265 recommendations separately, so do not assume an H.264 row applies unchanged to those codecs.
| YouTube H.264 setting | Recommended bitrate | Estimated transfer, continuous for 30 days |
|---|---|---|
| 240p–720p, 30 fps | 4 Mbps | 1,296 GB (1.296 TB) |
| 720p, 60 fps | 6 Mbps | 1,944 GB (1.944 TB) |
| 1080p, 30 fps | 10 Mbps | 3,240 GB (3.24 TB) |
| 1080p, 60 fps | 12 Mbps | 3,888 GB (3.888 TB) |
Each transfer figure is derived using the same 30-day calculation, with decimal GB and TB. For instance, 6 Mbps is six times the 1 Mbps baseline, so it is 1,944 GB. The table is useful for comparing settings, not for predicting a provider’s final meter reading.
A higher frame rate or resolution may call for a higher recommended bitrate, which increases the estimated monthly transfer in direct proportion. That does not mean you should always choose the lowest row: a static image and a fast-moving scene may not look equally acceptable at the same settings. You can use a test stream to check both visual quality and actual outgoing bitrate, then make a deliberate trade-off between picture requirements and transfer allowance.
The guide to looping videos on YouTube Live with FFmpeg addresses a common continuous-channel workflow. The playlist can repeat for days, but looping the same file does not reduce the egress calculation: the encoded stream still sends data at its configured rate for the time it remains live.
Adjust for shorter runtimes and different months
The formula is not limited to 24/7 operation. Replace the full-month seconds with your actual runtime. At the same bitrate, 12 hours a day for 30 days is half the time of a continuous stream, so the estimated transfer is half as much. A channel that runs only during evening hours should use the planned hours and days rather than the full-month total.
For a 31-day month, use 31 × 24 × 60 × 60 seconds; for a 28-day month, use 28 × 24 × 60 × 60. No special adjustment is required beyond runtime. If you start mid-month, calculate from the start time to the end of the billing period. If an outage interrupts the stream, actual transfer will be lower than a continuous estimate, although reconnects and retransmissions can complicate the provider’s total.
For a variable-bitrate stream, use the average outgoing bitrate over the same period you are estimating. A stream that peaks at 10 Mbps but commonly sends less may use less than a calculation based on 10 Mbps throughout. If you can access outbound-byte monitoring, summing actual bytes across the period is more useful than relying on a peak setting. Keep the monitoring interval and billing period in mind when comparing totals.
Do not confuse a safety margin for network capacity with extra transferred data. YouTube recommends leaving 20% room in available upload bandwidth and accounting for a primary and backup stream. The 20% is headroom in connection capacity, not an automatic 20% increase in encoded payload. If you transmit a backup stream at the same time as the primary, however, add its bitrate to the calculation because both streams are actually being sent.
Understand GB, GiB and provider metering
Decimal GB and binary GiB are different units. A decimal GB is 1,000,000,000 bytes; a GiB is 1,073,741,824 bytes. The 324 GB estimate for 1 Mbps over 30 days is decimal. Expressed in GiB, the same byte total is about 302 GiB. A dashboard that reports GiB can therefore show a smaller number than a decimal-GB calculation without measuring fewer bytes.
Read the wording on the provider’s plan page and dashboard carefully. “GB” may be used without a clear explanation of whether it means decimal gigabytes or a binary quantity; do not infer a provider’s accounting convention from the label alone. Check the plan’s included outbound transfer, whether an allowance is pooled across instances, how the billing period is defined, and what happens when the allowance is exceeded. The exact rules depend on provider, plan and region.
Metering scope also varies. Some providers distinguish inbound from outbound traffic, or treat private-network traffic differently from public outbound traffic. Others may pool allowances across eligible machines or report usage at intervals that do not align with your own tracking. DigitalOcean’s bandwidth billing documentation and Akamai’s network transfer documentation illustrate provider-specific accounting approaches; they are examples, not general rules or recommendations.
When comparing plans, put the included outbound amount into consistent units before comparing it with the estimate. Then check whether your other applications draw from the same pool and how overage is charged or otherwise handled. Do not use an allowance figure alone to select a VPS: network conditions, region, capacity and the provider’s monitoring tools matter as well. No plan allowance should be treated as a guarantee that a stream will perform as intended.
After the stream has run, compare your estimate with the provider dashboard over the matching billing period. If the dashboard is materially higher, investigate other outbound uses, any simultaneous backup stream, unit labels and the provider’s metering scope before assuming the encoder is sending more than expected. If it is lower, check whether the stream was paused, whether actual bitrate averaged below the configured target, and whether the dashboard has finished updating.
Allow for overhead and retransmissions
The calculation estimates encoded stream payload from bitrate and runtime. It does not add a universal percentage for network or protocol overhead, because the research basis does not establish a single factor that applies across providers and stream paths. Packets carry protocol information in addition to video and audio, and retransmissions can cause additional traffic, but their effect depends on conditions and accounting rules.
This is why the calculated examples should not be read as exact VPS bills. A provider may meter transfer differently from the simplified payload calculation; its dashboard may include other outbound activity on the VPS or pooled account, and its usage intervals may round totals. Decimal-versus-binary units can also change the displayed number. Check the vendor’s current billing documentation and terms for the plan you are considering rather than applying an invented overhead multiplier.
Keep two questions separate when planning. First, can the network sustain the outgoing bitrate with enough headroom for stable delivery? Second, how much outbound data is likely to accumulate under the provider’s accounting rules? YouTube’s recommended upload headroom helps with the first question. The bitrate-runtime formula addresses the second only as an estimate of stream payload.
For a stream with a primary and a concurrently transmitted backup, calculate their combined outgoing rate. For a backup that is merely configured but not sending, do not count its nominal bitrate as though it were traffic. Likewise, viewer count does not multiply VPS-to-YouTube ingest transfer; the relevant extra traffic is another stream actually leaving the VPS, not the number of people watching it.
A practical check is to record the encoder’s target and observed outgoing bitrate, note when the stream starts and stops, then compare the resulting estimate with the provider’s usage dashboard. If the encoder drops or reconnects, note those events too. The guide to restarting an FFmpeg stream after a process crash can help with recovery planning, but automatic restarts do not remove the need to check stream health or transfer usage.
Make the estimate useful before choosing a VPS
Write down four things before comparing plans: the configured bitrate, expected runtime in hours or seconds, the provider’s outbound allowance and unit, and whether other traffic shares that allowance. For example, a 10 Mbps stream running continuously for 30 days has an estimated 3.24 TB of decimal stream payload. Compare that with the provider’s own stated allowance only after checking its units, pooling and overage terms.
If you are not certain which bitrate to plan around, test the intended encoder settings and observe the outgoing rate under representative content. A still image, a bhajan video with gentle movement and a local news loop with frequent motion may not behave alike, especially with variable bitrate encoding. YouTube’s recommended settings are a starting point for the chosen codec and frame rate, not a promise about the exact traffic your VPS will record.
Avoid buying a large transfer allowance solely from a single peak reading, but do not assume an average will always hold if content changes. A new schedule, higher frame rate, concurrent backup or second channel changes the inputs. Recalculate when the actual bitrate or runtime changes, and check the dashboard after the first billing period so that your next estimate reflects measured usage.
If keeping a personal computer running is the source of operational friction, StreamNeo removes that particular need by turning an uploaded video into a YouTube live stream that continues with your computer switched off. It does not change the importance of choosing a suitable bitrate or understanding YouTube and provider requirements.

FAQ
How much data does a 1 Mbps 24/7 stream use in a month?
At a steady 1 Mbps for 30 days, the estimate is about 324 decimal GB. It is derived from bitrate and runtime and excludes any unspecified overhead, retransmissions or provider-specific metering differences.
Does YouTube’s 20% upload headroom add 20% to monthly transfer?
No. That recommendation concerns spare connection capacity for stability, not an automatic increase in the encoded payload sent. Include another stream only if it is actually transmitted at the same time.
Do more viewers increase VPS egress?
Not for the VPS-to-YouTube ingest stream: YouTube transcodes the incoming stream for playback. Your VPS transfer depends on its outgoing stream or streams, their bitrate and how long they are sent.
Why does my VPS dashboard not match the estimate?
The estimate uses decimal units and simplified stream payload, while a provider may use binary units, include other outbound traffic, meter at intervals or apply its own accounting scope. Compare the plan’s terms and dashboard period, and treat the calculation as a planning estimate rather than an exact bill.
