How much does a 24/7 YouTube stream cost with FFmpeg on a low-power Celeron PC? There is no responsible universal total: you need the whole computer’s measured power while streaming, your electricity rate and any extra internet or equipment costs.
For a 30-day month, continuous streaming is 720 hours. Multiply average wall power in kilowatts by those hours and your local price per kWh; then list internet, software and hardware costs separately. The examples below are hypothetical, not typical Celeron measurements.
Define the setup you are pricing
The calculation applies to a PC running FFmpeg continuously and sending a live feed to YouTube. It includes the complete computer at the wall: processor, memory, storage, graphics hardware, fans and power supply. It does not mean the processor alone, nor does a Celeron model name establish how much the assembled machine will draw.
You are pricing a workload as well as a box. The source file, output resolution, frame rate, codec, filters and whether encoding uses the processor or supported graphics hardware all affect what the PC has to do. A machine playing a file without changing its format may have a different load from one decoding, filtering and re-encoding it. This article does not provide a tested benchmark for any Celeron model or FFmpeg command.
YouTube’s encoder instructions explain entering the live server URL and stream key in an encoder. Its live encoder settings give recommendations by codec, resolution and frame rate, and describe RTMP/RTMPS, constant bitrate and a recommended two-second keyframe interval. Treat those as ingest guidance, not a guarantee that your PC or internet connection can sustain a chosen setting.
Before estimating cost, settle on the stream configuration you actually intend to run. If you are checking choices for a local channel, the practical discussion of OBS settings for a 24/7 stream in India can help frame the settings question; it does not substitute for testing your own FFmpeg setup. Also check that the channel can go live using YouTube’s live streaming restrictions checklist.
Count the hours in a continuous month
A convenient calculation month is 30 days: 30 × 24 = 720 streaming hours. This is arithmetic for the example month, not a claim about the length of every calendar month. If your stream is interrupted for planned maintenance or is only live part of the day, use the hours it actually runs rather than 720.
For a month with a different number of days, use days × 24 for a continuous schedule. For example, the formula works just as well with 28 or 31 days; use the relevant calendar period when comparing your electricity bill. If the stream starts partway through a billing cycle, count only the hours in that cycle.
The hours should describe the powered workload, not just the time viewers can see the channel. A PC left running while FFmpeg is stopped still uses power, but at a different draw. If you want the cost of the whole always-on arrangement, measure that arrangement through representative streaming and idle periods or calculate those periods separately. Do not count an idle overnight draw as if it were the streaming draw if the stream is meant to run all night.
A continuous channel also needs attention to more than monthly arithmetic. Test the output and monitor YouTube’s stream health. Its encoder guidance says streams under 12 hours are automatically archived; that is not a promise of uninterrupted operation or a prescribed restart schedule. A restart or watchdog may be an implementation consideration for your own setup, but neither should be folded into an assumed platform guarantee.
Measure the whole system at the wall
The useful input is average wall power in watts while your actual stream runs. A plug-in electricity usage monitor is a practical way to read it: connect the PC through the monitor, run FFmpeg with the file, settings and network arrangement you plan to use, and record a representative average. The monitor measures input for the complete device, including the power supply’s conversion losses, rather than estimating from a processor label.
A short reading can be misleading if the workload varies. Video content, filters, encoding mode and background activity may change the draw. Let the stream settle, observe it across representative content, and note whether you measured only the PC or also a display, router or other equipment. Add those other devices only if they are part of the cost you want to estimate, and avoid counting them twice if their electricity is already in another household calculation.
Intel documents why a nominal processor figure is not a system measurement: power depends on workload and system design. Its 2014 power guideline includes a specific Celeron 2000E configuration with figures for idle states and 1080p video decoding. Those values describe that configuration and activity, not a transferable wall-power estimate for an unknown mini PC running FFmpeg. In particular, they are not a measured 24/7 FFmpeg stream result.
FFmpeg’s documentation on Intel Quick Sync Video describes an acceleration path with requirements that include support from both the decoder and encoder and, for the documented mode, no filters. The exact Celeron generation, graphics hardware, driver, FFmpeg build and filter chain matter. Hardware encoding might reduce processor work in a supported setup, but do not assume it from the word “Celeron”; measure the configuration you will actually use.
Convert watts and hours into energy
The calculation is:
Monthly kWh = (average wall watts ÷ 1,000) × streaming hours
Dividing watts by 1,000 converts them to kilowatts. Multiplying by hours gives kilowatt-hours, the energy unit commonly used on electricity bills. For a 30-day continuous month, substitute 720 hours:
Monthly kWh = (P ÷ 1,000) × 720, where P is your measured average wall draw in watts.
For a transparent hypothetical example, suppose a wall monitor reads an average of 20 W during the intended stream. That assumed input gives (20 ÷ 1,000) × 720 = 14.4 kWh for the 30-day example month. This is arithmetic only; 20 W is not a typical Celeron figure, a benchmark, or a prediction for your computer.
If the measured draw changes materially between modes, calculate them separately rather than forcing one number onto the whole month. For instance, take the measured streaming watts multiplied by streaming hours, plus measured idle watts multiplied by idle hours. This is useful when a channel is scheduled for part of the day but its PC remains switched on, or when you want to price maintenance time separately.
Apply your electricity rate
Once you have kWh, multiply by the rate that applies to your own bill:
Electricity cost = monthly kWh × your price per kWh
Bills can include charges beyond a simple energy rate, and tariffs vary by location and account. Use the per-kWh rate and billing basis that best represents what another unit of consumption costs you. If your bill uses slabs or time-dependent rates, the marginal rate for extra use may differ from an average calculated across the full bill. Check your current bill or electricity supplier’s tariff rather than borrowing a rate from another city or country.
Here is a second hypothetical scenario, solely to show the arithmetic. If the measured average is assumed to be 20 W and the assumed rate is 8 currency units per kWh, the example energy is 14.4 kWh and the resulting electricity component is 115.2 currency units. Neither input is a quoted tariff or a claim about a typical system; replace both with your measurement and local rate. If your actual rate is quoted in a different currency, keep the calculation in that currency.
| Input or result | Hypothetical example | Replace it with |
|---|---|---|
| Average whole-system draw | 20 W | Your measured wall watts |
| Hours streamed in a 30-day month | 720 hours | Your actual monthly hours |
| Energy | 14.4 kWh | (watts ÷ 1,000) × hours |
| Electricity rate | 8 currency units/kWh | Your applicable local rate |
| Electricity component | 115.2 currency units | kWh × rate |
The table deliberately leaves the currency unnamed. It is not a universal dollar total, and it excludes internet, software and equipment costs. A change in either assumed input changes the result directly: twice the measured draw or twice the rate means twice the electricity component for the same number of hours.
Keep internet, software and hardware separate
Electricity is only one part of a 24/7 setup. The PC needs a sustained upload connection, and your ISP’s data terms, fair-use policy or overage charges can matter. Check the plan you actually have and the expected upload demand for the selected settings. YouTube recommends testing upload bitrate and gives different ingest bitrate recommendations by codec and video mode; its figures are recommendations, not a measurement of your connection or a promise that an ISP allows unlimited use.
If your ISP charges a fixed monthly amount regardless of streaming, show that amount as the internet line item only if you are counting the whole plan in your channel budget. If the stream could trigger an overage, estimate that charge from your provider’s current terms. There is no universal data allowance or overage cost to add here. Lower output settings may reduce upload demand, but should still suit the picture you want to present and must be tested for stable delivery.
Software can be zero additional cost if you use software already available to you, or it can have a separate licence or service charge if your chosen configuration requires one. Do not assume a paid encoder, hosted service or plug-in is necessary from the title alone. Record any recurring charge in its own row, with the vendor and the date you checked the current terms; there is no software price in this calculation.
Hardware has both an upfront and a replacement cost. If you already own the PC, its purchase price is not a new monthly electricity charge. For planning, you may choose to spread the purchase or replacement budget over the months you expect to use it, but that is your accounting choice, not an operating tariff. Keep the original purchase amount, any replacement reserve, and any optional power protection distinct from the energy bill so that comparisons do not conceal what is recurring and what is a one-off expense.
Reliability also has a cost in time. A low-power machine that needs frequent manual intervention may not be the least costly option for a channel whose stream must run unattended overnight. Conversely, a dedicated PC can make sense when you need local control, other software or interaction that an uploaded-file loop does not provide. For a channel built around a prepared video, StreamNeo removes the need to keep your own computer running for that broadcast by turning an uploaded file into a YouTube live stream; it is not an FFmpeg process running on your PC.
If the broadcast is a prepared playlist rather than a single file, compare how you will handle transitions and continuous playback, not only watts. These guides to streaming multiple videos continuously and building a continuous YouTube playlist cover workflow choices that can change what equipment and attention your channel needs. A simpler workflow may reduce operational effort, but does not establish a particular electricity saving.
Estimate your own monthly total
Make a small worksheet with one line for each cost category. Start with the observed stream watts, monthly hours and tariff. Then add only costs that apply to your account or arrangement, rather than filling unknown values with a generic allowance.
| Cost line | How to enter it | Evidence to use |
|---|---|---|
| Electricity | (measured watts ÷ 1,000) × hours × rate | Wall monitor, hours and current bill |
| Internet | Fixed plan share or applicable overage | ISP bill and current data terms |
| Software or hosting | Actual recurring charge, if any | Vendor terms checked for your use |
| Hardware reserve | Your chosen purchase/replacement allocation | Your purchase budget and planning period |
| Other equipment | Include only devices in scope | Separate measurement or bill data |
Keep the measurement conditions beside the number: machine model, FFmpeg version and settings, stream resolution and frame rate, encoding path, and whether the reading includes a display or network equipment. That note makes a future comparison meaningful. If you change codec, add filters, raise frame rate, replace the file source or move from wired to wireless networking, test again rather than carrying over an old reading as if the workload were unchanged.
For a fair comparison between a Celeron desktop, another PC or a hosted option, compare the same video settings and hours where possible. Look at measured average wall draw, electricity tariff, upload capability and data terms, plus any recurring service cost. Also account for whether the machine can encode with its supported hardware path and whether you can monitor and recover the stream. A cheaper electricity line does not settle the decision if the stream is harder to keep working; an external service charge does not tell you what your total would be without the PC and network costs it replaces.
Write down assumptions explicitly. If the monitor is unavailable, you can still use the formula once you obtain a reliable measurement, but do not replace it with a processor TDP or a number found for a different model. Until then, leave the electricity estimate as an unknown rather than presenting a false precision. That is more useful than a confident monthly total built on an unmeasured Celeron label.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
How much electricity does a mini PC use running 24/7?
It depends on measured whole-system wall draw under the workload you intend to run. Measure the computer while FFmpeg is streaming, then multiply watts divided by 1,000 by the hours and your local electricity rate. A mini PC label or processor specification is not a substitute for that measurement.
Can a Celeron PC stream to YouTube all day?
It may be able to, but the Celeron name alone does not establish encoding support, upload capacity or stability. Test the exact source, settings, FFmpeg build and network connection, and monitor YouTube’s stream health. Do not treat a short successful test as proof of uninterrupted 24/7 operation.
Do Intel Quick Sync or lower bitrate settings guarantee a cheaper stream?
No. Quick Sync support depends on the particular hardware and software path, and YouTube’s bitrate guidance is not a power benchmark. Measure the whole setup after selecting settings that your connection can sustain; any electricity difference must come from that measurement.
What should I do if I do not know my electricity rate or power draw?
Use your current electricity bill or supplier tariff for the marginal per-kWh rate, and obtain a wall-power reading during the intended workload. Keep ISP, software and hardware costs as separate unknowns until you can verify them. Do not fill gaps with a universal total, because both the rate and the computer’s actual draw vary.
