A mini PC drawing 20 watts continuously uses 0.48 kWh (0.48 units) a day, 14.4 kWh in a 30-day month, and 175.2 kWh in a 365-day year. The rupee cost depends on your electricity tariff, consumption slab, and bill adjustments; there is no single India-wide household rate to apply. These figures assume a steady 20 W draw at the wall, not a measured result for every mini PC.
How much electricity does a 20 W mini PC use?
Use the average power draw in watts multiplied by operating hours, then divide by 1,000 to get kilowatt-hours (kWh): average watts × hours ÷ 1,000 = kWh. Electricity bills commonly call one kWh a unit.

| Period | Calculation at 20 W, 24 hours a day | Energy used |
|---|---|---|
| One day | 20 × 24 ÷ 1,000 | 0.48 kWh |
| 30-day month | 0.48 × 30 | 14.4 kWh |
| 365-day year | 0.48 × 365 | 175.2 kWh |
These are arithmetic estimates for the stated 20 W continuous load. They do not establish that a particular mini PC draws 20 W from the wall while streaming. Actual consumption can differ with the computer, workload, peripherals, and power-supply losses. If your setup averages 15 W or 30 W instead, substitute that value in the formula rather than treating 20 W as a measured fact.

How to estimate the rupee cost on your electricity bill
- Find the average wall draw. Use a plug-in electricity monitor that reports watts or kWh, if available, while the complete streaming setup is running. ENERGY STAR includes plug-load and home energy monitors among the capabilities in its home energy management criteria; that is an example of a measurement approach, not a recommendation of a particular model or a guarantee of device accuracy.
- Calculate usage for the billing period. Multiply the average watts by the hours used and divide by 1,000. For a continuous 20 W load over 30 days, that is 14.4 kWh.
- Check your own tariff and bill. Use the schedule for your state or union territory, distribution utility, domestic consumer category, and consumption slab. The Ministry of Power says tariffs are determined by the appropriate electricity regulatory commissions, and state governments may provide subsidies to consumer classes, including domestic consumers. See the Ministry’s 10 August 2026 reply.
- Estimate the incremental energy charge. Multiply the added kWh by the relevant per-unit rate. If the tariff is slab-based, the added use may fall at a different marginal rate depending on the household’s total consumption and the schedule’s rules.
- Keep energy charges separate from the full bill. A kWh calculation estimates the energy-charge component only. Fixed charges and other local bill items, as well as subsidy treatment, can change what a household ultimately pays.
A dated local tariff example: Lakshadweep FY 2026-27
The Department of Electricity, Lakshadweep lists the following domestic LTDS-II energy rates for FY 2026-27, along with a fixed charge of ₹25 per kW per month or part thereof. This is a local illustration, not an India-wide household tariff. Applying each listed energy rate to 14.4 kWh shows how the energy-charge arithmetic changes by rate; it does not predict a household’s complete bill.

| Lakshadweep LTDS-II consumption slab (FY 2026-27) | Listed energy rate | 14.4 kWh multiplied by that rate |
|---|---|---|
| 0–100 units | ₹3.55/kWh | ₹51.12 |
| 101–200 units | ₹5.30/kWh | ₹76.32 |
| 201–300 units | ₹7.70/kWh | ₹110.88 |
| 301–400 units | ₹10.05/kWh | ₹144.72 |
| Above 400 units | ₹13.05/kWh | ₹187.92 |
Rates and fixed charge are from the Lakshadweep Electricity Tariff Schedule. The multiplication figures are for a 30-day 20 W estimate and are energy-charge arithmetic only. Which rate applies to additional use depends on the household’s slab and the tariff’s billing method; the fixed charge and other bill components are not included in the table.
Does a 24/7 stream need to run on your mini PC?
If you want the stream to continue from your own equipment, the electricity estimate is only one part of the cost: the mini PC and its internet connection must remain available. For a cloud alternative, StreamNeo keeps a YouTube channel live from uploaded videos without requiring your computer or home connection to stay on. Upload a recording or build a playlist, add your YouTube stream key once, and go live; the service loops the uploaded video from the cloud. It is for uploaded video playback, not a live camera feed.

- It estimates energy for a continuous 20 W load, not the measured draw of a specific mini PC and streaming setup.
- It does not establish a universal Indian unit rate. State and utility tariffs, consumer categories, slabs, and subsidy policies vary.
- It is not a full-bill forecast: fixed charges and other local adjustments are outside the kWh multiplication.
- For a comparison between running a PC and another option, compare measured average wall watts, hours of operation, applicable marginal tariff, fixed charges and subsidy treatment over the same billing period.
The Central Electricity Authority lists a report titled “Tariff and Duty of Electricity Supply in India – March 2026,” but no India-wide average is used here; a local schedule and your own bill are the relevant inputs for estimating your household’s cost. The report listing is available from the CEA Financial Studies and Assistance Division.
