There is no single reliable monthly cost: it depends on the PC’s measured power draw at the wall, inverter losses and operating mode, and your state, DISCOM, consumer category and tariff slab. For a 30-day month, every 100 W of average continuous input uses 72 kWh (units); multiply your calculated units by the rates and other charges on your own bill.
Calculate the PC’s monthly electricity use
Use average AC input power in watts—not the power supply’s maximum rating—and include the hours and days the PC actually runs:
Monthly energy (kWh) = average AC input watts × hours per day × days ÷ 1,000.
For continuous operation over 30 days, this simplifies to average watts × 0.72 = monthly kWh. For example, a measured average input of 100 W would use 72 kWh in 30 days. That is arithmetic, not a claim about what a particular streaming PC consumes.

- Watts (W) describe instantaneous power draw.
- Kilowatt-hours (kWh), or units describe accumulated energy. Indian electricity bills commonly express energy use in units.
- Rupees are the resulting charges, which may include more than the energy rate per unit.
Measure the complete setup under its real workload
Measure AC input, not the PSU rating
A desktop power supply’s rated capacity is not the PC’s usual consumption. Measure the complete PC at the AC input while it runs the streaming workload you intend to use. A brief idle reading may miss changes in draw; observe a representative period and, if possible, use a meter that records accumulated kWh. ENERGY STAR’s computer measurement procedure calls for an approved true-power meter at the AC source and says the computer should connect directly to the measurement outlet, without a UPS between the meter and computer. That is a controlled measurement procedure; a real-world estimate should reflect your actual use.
Account for the inverter without guessing a loss percentage
To capture inverter overhead and conversion losses, measure the inverter’s AC input while it powers the PC, or measure the PC load and apply the inverter’s efficiency at that load. Schneider Electric defines UPS efficiency as output electrical power divided by input electrical power; the difference is lost energy, and efficiency varies with load. A stated maximum efficiency may therefore not represent your operating conditions.

When mains power is available, the inverter may pass power through while adding standby or charger overhead, depending on its model and mode. During an outage, the battery supplies energy and later recharging incurs losses. The extra grid consumption is not a universal fixed percentage: measure the system input or consult the manufacturer’s efficiency information for the relevant load.

Turn your units into a local rupee estimate
India has no single household electricity rate that applies to everyone. The Ministry of Power says retail tariffs are determined by the appropriate Electricity Regulatory Commissions, and state governments may subsidize particular consumer classes. Your state, DISCOM, consumer category and applicable tariff schedule matter. The Central Electricity Authority’s March 2026 tariff compilation likewise records state- and category-specific schedules, including fixed charges, energy rates and subsidies.

- Read your latest bill to identify your consumer category, billing period, tariff structure and current charges.
- Calculate the PC’s additional monthly units using your measured average AC input. If the measured value already includes inverter input, do not add a separate estimated loss.
- Apply the applicable tariff to the additional units, accounting for whether the schedule is telescopic or uses another structure, and whether those units move your household into a different slab.
- For a more realistic bill estimate, consider fixed charges, duties or taxes, fuel or power-purchase adjustments, local charges and any subsidy shown on your bill. Compare the bill under the same schedule with and without the PC’s added units.
A dated example: Chhattisgarh FY 2026–27
The Chhattisgarh State Electricity Regulatory Commission’s FY 2026–27 domestic schedule lists these telescopic energy-charge slabs. They are a Chhattisgarh example, not an India-wide household rate; the schedule separately lists monthly fixed charges per kW and notes that state subsidies may apply.
| Monthly domestic energy slab | Energy charge in the FY 2026–27 schedule |
|---|---|
| 101–200 units | ₹4.50/kWh |
| 201–400 units | ₹6.00/kWh |
| 401–600 units | ₹7.00/kWh |
| Above 600 units | ₹8.80/kWh |
Under a telescopic schedule, the rate applies to units in each slab rather than necessarily to every unit at the highest slab reached. The commission’s example says a 150-unit bill uses the first-slab rate for the first 100 units and the next-slab rate for the remaining 50. For your own bill, use the latest tariff order and rules applicable to your location and category.
