Compute monthly electricity bill for 1800W induction cooktop stove cooking compared to LPG gas cylinder.
Understanding how much power your induction cooktop consumes is essential for controlling monthly household utility bills. In India, power rates vary between ₹3.00 and ₹11.00 per kWh unit depending on your state tariff slab tier.
Operating a induction cooktop with high energy efficiency ratings (5-Star or Inverter technology) significantly lowers your overall unit consumption, keeping your meter within lower pricing slabs.
Example: 1800 Watts × 1.5 Hours × 30 Days ÷ 1000 = 81 kWh units per month.
Check the specification sticker on your induction cooktop for rated wattage (e.g. 1800W).
Multiply wattage by operating hours per day and 30 days to get monthly Watt-hours, then divide by 1,000 for kWh units.
Multiply net monthly kWh units by your state electricity tariff slab rate (e.g. ₹7.00/unit) to find total monthly cost.
| Induction Cooktop Specification / Variant | Wattage (W) | Daily Usage (Hrs) | Monthly Units (kWh) | Est. Monthly Bill (₹) |
|---|---|---|---|---|
| Induction Cooktop (1200W Low Power) | 1200 W | 1.5 hrs/day | 54 kWh | ₹378 |
| Induction Cooktop (1800W Standard) | 1800 W | 1.5 hrs/day | 81 kWh | ₹567 |
| Induction Cooktop (2100W High Power) | 2100 W | 1.5 hrs/day | 94 kWh | ₹658 |
| Appliance Energy Technology | Annual Units (kWh) | Est. Annual Electricity Bill (₹) | Energy Rating |
|---|---|---|---|
| LPG Gas Cylinder Cooking | 0 kWh/yr | ₹10,800 | 12 Cylinders @ ₹900 |
| 1800W Induction Stove Cooking | 972 kWh/yr | ₹6,804 | Best (Saves ₹3,996/yr) |
Yes, induction cooktops have 85-90% heating efficiency compared to LPG gas stove (40-50% efficiency). Cooking on induction typically costs 30% to 40% less than using an LPG cylinder.
See how much money you can save every month by installing rooftop solar panels with Central Government subsidy.
Simple household adjustments can reduce your monthly power consumption and keep you in lower tariff slabs.
Each degree higher saves ~6% electricity. Running at 24°C instead of 18°C can lower your monthly cooling bill by ~24%.
Brushless DC (BLDC) motor fans consume only 28W compared to 75W for traditional ceiling fans, cutting fan power usage by over 60%.
Appliances in standby mode (TVs, set-top boxes, chargers) consume 5–10% idle electricity. Turn them off at the main switch.
Residential rooftop solar installations receive up to ₹78,000 in central subsidies, generating free green power with net-metering.
Clean refrigerator condenser coils annually and set geysers to 50°C with an auto-timer to prevent overheating and energy waste.
Energy-efficient 9W LED bulbs output the same light as 60W incandescent lamps while consuming 85% less electricity.
Consumed units (kWh) are split into progressive tariff tiers with respective unit rates.
Monthly fixed charges are calculated per kW (or kVA) of sanctioned load.
Fuel Adjustment Charges (FAC/FPPPA) and state electricity duty percentages are added.
State government zero-bill / free unit schemes (e.g. Gruha Jyothi, DERC) are deducted for the final estimate.
