AC Electricity Cost Per Hour in India
Estimate hourly and monthly AC electricity cost based on wattage, usage, and tariff.
Quick Answer
AC electricity cost per hour depends on actual watt draw, compressor duty cycle, and effective unit tariff including slab impact.
Key Points
- AC nameplate tonnage is not equal to constant hourly consumption.
- Compressor cycles change real kWh use by temperature and insulation.
- Even moderate daily usage can push household into higher slab.
- Estimate AC separately before adding other home loads.
Examples
Hourly estimate
If effective AC draw averages 1.2 kWh and tariff is Rs 8.5, one hour costs about Rs 10.2.
Monthly impact
At 6 hours/day, monthly AC consumption can exceed 200 units and dominate bill composition.
