There is no single monthly electricity cost for running FFmpeg on a Raspberry Pi for YouTube in India. Estimate it from the whole setup’s average wall draw, the number of days in your billing period and the marginal tariff that applies to your household.
Use this formula: monthly cost (₹) = average wall draw (W) × 24 × billing-period days ÷ 1,000 × marginal tariff (₹/kWh). For a 30-day period, that simplifies to 0.72 × watts × tariff. The example later uses 10 W and ₹6/kWh only to show the arithmetic; neither is a measurement or a representative India-wide figure.
What determines the monthly electricity cost
The result depends on three inputs: how much power the complete setup draws at the wall, how long it runs during the billing period, and the rate your next units of electricity are charged at. The title’s reference to FFmpeg does not by itself specify a wattage. A Pi model, source file and workload have to be identified and measured before you can estimate that part.
A file that is already encoded and sent onward is a different workload from one being transcoded in real time. Other tasks, such as combining or repackaging streams, can also affect what the computer is doing. The research available for this article does not establish a measured draw or performance result for an unspecified Pi, video format or FFmpeg command. Avoid using a watt figure from a different setup as if it were yours.
The electricity estimate is also narrower than the cost of operating a live channel. It does not include the Raspberry Pi and power supply purchase, internet service, storage replacement or the value of the time you spend checking the stream. Keep those costs separate so that a low electricity estimate is not mistaken for a low total cost of ownership.
Measure the whole setup at the wall
A useful reading is the power entering the entire streaming setup from the mains. That includes the Pi, the power supply’s conversion losses, and anything powered through the setup that you want to include, such as attached storage or a USB device. If a screen, router or separate audio device is part of the always-on arrangement, decide whether to include it. Be consistent: compare like with like.
Raspberry Pi’s official computer hardware documentation warns that its power measurements are approximate and do not account for additional USB devices; attached devices or a HAT can raise consumption. Its model-specific figures are useful context, not a substitute for a wall reading of your actual assembly and workload.
A plug-in electricity usage meter can show the wall draw or accumulated energy for the connected equipment. Use one only if its instructions and electrical rating are appropriate for your supply and load. For a continuous stream, take a reading after the Pi has been running the actual FFmpeg job long enough to be in its normal operating state. If activity varies, observe it over a representative period rather than treating a brief idle reading as the average.
Write down what the test includes: Pi model, power supply, attached devices, workload and whether the reading is a momentary watt figure or accumulated kWh. If your meter reports only energy over a test window, divide that kWh by the window’s hours and multiply by 1,000 to get average watts. Do not add a PSU’s rated capacity to the measured figure; the rating describes what it can supply, not what the setup continuously consumes.
Calculate monthly kWh
Convert watts to kilowatts by dividing by 1,000, then multiply by the hours the setup runs. A continuous system is usually estimated as 24 hours per day for each day in the billing period:
Monthly energy (kWh) = average wall draw (W) ÷ 1,000 × 24 × billing-period days.
For 30 days, the hours total 720. For 31 days, they total 744. Thus a setup drawing the same average power for 31 days uses 31/30 as much energy as it would over 30 days. Use the actual dates on the bill rather than assuming every billing period is exactly a calendar month.
Here is the arithmetic for several assumed average draws over 30 days. These wattages are examples for calculation, not measured Raspberry Pi results:
| Assumed wall draw | 30-day energy | Cost at an assumed ₹6/kWh |
|---|---|---|
| 5 W | 3.6 kWh | ₹21.60 |
| 10 W | 7.2 kWh | ₹43.20 |
| 15 W | 10.8 kWh | ₹64.80 |
The table isolates the multiplication. It does not say that a particular Pi will draw 5, 10 or 15 W, or that ₹6/kWh is the price in your area. Replace both inputs with your measured setup and applicable tariff. If your average draw changes between idle periods and busy encoding, use an average that reflects the full operating pattern, not just its peak or its quietest moment.
Apply your local marginal tariff
The rate to use is the marginal rate for the additional units your setup causes you to consume, not automatically a national average or the first rate shown on a tariff leaflet. Domestic tariffs can vary by state, utility, consumer category and consumption slab. The Central Electricity Authority’s 2025 tariff publication gives a state, utility and category breakdown; it includes a Goa domestic average billing rate of ₹3.50/kWh. That is one published entry, not a national rate or a recommendation for your calculation.
Check the current tariff applicable to your connection and the usage band your household is in. If the added units remain within one band, that band’s marginal rate may be a reasonable input. If they push consumption into a higher band, some units may be charged differently. Subsidies, duties and other bill adjustments can further affect the amount you pay, so use your current utility bill or tariff schedule to understand the relevant treatment.
For a quick estimate, multiply the added kWh by the applicable marginal rate. If the utility uses different rates across blocks of consumption, split the added units across those blocks instead of applying one rate to all of them. This is still an estimate: billing rules and adjustments are utility-specific. The practical question is what extra amount the setup adds to your bill, rather than what portion of every bill item can be assigned to one small appliance.
Work through the illustrative 10 W example
Suppose, purely for arithmetic, that a wall meter showed an average of 10 W for the complete setup, that it ran for 30 days, and that the relevant marginal rate were ₹6/kWh. The energy calculation is 10 ÷ 1,000 × 24 × 30 = 7.2 kWh. The cost calculation is 7.2 × ₹6 = ₹43.20.
That ₹43.20 is an illustrative result, not a test of a Raspberry Pi and not a typical monthly bill for India. The 10 W is an assumed draw, and ₹6/kWh is an assumed rate. Your bill may be lower or higher because your reading, billing period, slab and utility tariff differ. This is why the formula is more useful than quoting a single monthly amount.
If the same assumed 10 W continued for 31 days at the same assumed rate, the setup would use 7.44 kWh, or 31/30 of the 30-day energy. At the same illustrative rate the arithmetic would be ₹44.64. Again, this is only a day-count adjustment to the example, not a forecast for a real household.
A common source of confusion is the power supply label. Raspberry Pi’s documentation lists recommended supply capacities of 27 W for Pi 5 and 15 W for Pi 4 Model B. Those are supply recommendations, not evidence that either board consumes that many watts all day. Nor does a recommended supply rating tell you how much a particular FFmpeg workload will draw. Measure the assembled equipment at the wall.
Account for peripherals, slabs and bill components
A bare-board estimate can miss devices needed to make the channel work. Storage may be attached; USB accessories or a HAT may be present; a network connection may involve equipment that is also left on for other purposes. Decide what belongs in the comparison. If you are asking how much the whole streaming arrangement adds, include only equipment that is on because of the stream, or measure the system in both states and compare the difference.
Do not assign a household’s entire fixed charge to the Pi. A fixed charge generally exists independently of the extra kWh; it is not an electricity cost caused by one device. Attribute a fixed or tier-related change only where the Pi’s consumption actually changes the applicable bill tier or bill treatment. Keep the direct energy multiplication distinct from the full bill, which may contain other components.
Slabs matter most when the added consumption straddles a threshold. For example, if your household is close to a band limit, a small continuous load could cause some units to be billed at a different marginal rate, depending on your utility’s rules. Do not assume this happens, and do not allocate a higher rate to all household units just because the stream adds some usage. Read the current schedule and calculate only the increment under its actual structure.
There is also a workload trade-off behind the meter reading. If the source has already been encoded for the intended stream, avoid assuming that FFmpeg is doing the same amount of work as a live transcode. YouTube’s recommended upload encoding settings provide guidance on formats and frame rate; they do not certify that a particular Pi can encode a given stream reliably. Test the exact media and settings before relying on the setup overnight. The video encoding requirements for pre-recorded content are a useful companion when checking the file you plan to send.
Compare electricity with other setup costs
Electricity is only one line in the monthly comparison. Put it beside the hardware’s upfront purchase, replacement storage, internet connection and whatever ongoing support or monitoring you need. A Pi may make sense when you already own the board, want to control the setup locally and are comfortable maintaining the stream. Its low measured energy cost does not remove the responsibility to recover from a network or software failure.
It also matters whether your planned command is practical for your exact board and source. YouTube’s encoding recommendations are platform guidance, not a Pi performance guarantee. Check the file’s format and frame rate, then run the intended FFmpeg workflow long enough to notice heat, dropped frames, power interruptions and reconnection behaviour. The Hindi devotional FFmpeg Raspberry Pi setup guide can help you think through the software arrangement, while a guide to recovering a YouTube stream after an internet outage covers a separate operational risk. Neither changes the need to test your own connection and files.
A hosted arrangement changes which work you do yourself; it does not make internet availability irrelevant, and it has a recurring service cost rather than just the Pi’s electricity increment. If the part that worries you is leaving a home computer running and manually restarting a dropped broadcast, StreamNeo turns an uploaded video into a YouTube live stream that can continue with your computer switched off and is monitored and restarted if it drops. It is YouTube-only, so it is not the right fit if you need another destination or want to manage the broadcast locally.
Compare options using the same period and scope: full monthly cash outlay, who supplies the continuous internet connection, who handles restart and monitoring tasks, whether your media needs real-time encoding, and hardware cost versus recurring charges. A one-month electricity calculation should not be compared with a service fee as though they include the same responsibilities. Where you value direct control and already have suitable equipment, local running may be preferable; where reducing home-computer and restart duties matters more, a managed option may be worth assessing. Confirm current terms before deciding.

FAQ
How much does it cost to run a Raspberry Pi for 24/7 streaming in India?
There is no single India-wide amount. Multiply your measured average wall draw by 24 hours and billing-period days, divide by 1,000 to get kWh, then multiply by your applicable marginal tariff. Your Pi model, attached equipment, workload and local bill structure determine the inputs.
Is 10 W a normal Raspberry Pi draw for FFmpeg?
This article does not present 10 W as a normal or measured draw. It is an assumption used to demonstrate the calculation. Measure your complete setup while it runs the exact job you intend to use.
Can I use ₹6 per kWh for my estimate?
Only if that is the relevant marginal rate for your connection and consumption band. The ₹6 figure here is illustrative arithmetic, not a universal Indian tariff. Check your current utility bill and tariff schedule.
Does the Pi’s recommended power supply wattage equal its electricity use?
No. A supply recommendation describes the capacity of the power supply, not continuous consumption by the board. To estimate the additional electricity cost, measure the assembled setup at the wall and apply your billing period and tariff.
