LPG vs Induction Cooking Cost Calculator India — Which Is Cheaper in 2025?
Compare monthly cooking costs between a 14.2 kg domestic LPG cylinder and an 1800W induction cooktop for an Indian household of 4. Includes thermal efficiency, fuel economics, and 2025 price comparison.
Cooking Usage & Fuel Pricing
Sum of breakfast, lunch, and dinner stove time.
Subsidized / domestic retail cylinder rate.
Average rate per kWh in your home.
Consumes ~1 cylinder(s) monthly. Around 40% of the gas flame heat escapes around the vessel into the ambient kitchen.
Consumes 76 units monthly. Electromagnetic energy heats the pan directly with zero open flame and zero hot kitchen sweat.
Induction Boils 50% Faster with Zero Ambient Kitchen Heat
While monthly operating costs between LPG and electricity are closely comparable (₹850 vs ₹570), pairing induction with a rooftop solar system makes your cooking 100% free forever.
Frequently Asked Questions
Q:Why is induction cooking more thermally efficient than an LPG gas stove?
A traditional gas stove burner transfers only about 55% to 60% of its heat into the cooking vessel; the remaining 40% escapes as hot ambient air into the kitchen. In contrast, induction cooktops use electromagnetic induction to generate heat directly inside the ferrous cooking pan itself, achieving 84% to 90% thermal transfer efficiency — making induction 30–35% more efficient than LPG per unit of food cooked.
Q:How many units of electricity does an induction cooktop consume for 1 hour of cooking?
A standard 1800W induction cooktop set to maximum heat consumes 1.8 units (kWh) per hour. In practice, most cooking uses medium heat settings (900W–1200W), consuming 0.9 to 1.2 units per hour. A family of 4 cooking for 2 hours daily consumes approximately 54 to 72 units per month on induction, costing ₹430–₹575 at ₹8/unit.
Q:How many LPG cylinders does an average Indian family use per month?
An average Indian family of 4 cooking 3 meals daily uses approximately 0.8 to 1.0 LPG cylinders per month (14.2 kg domestic). At the 2025 subsidized price of approximately ₹900–₹950 per cylinder in major cities, monthly LPG cooking cost is ₹720 to ₹950. Larger families or those making traditional slow-cooked dishes use up to 1.5 cylinders per month.
Q:Is induction cooking cheaper than LPG in India in 2025?
At current 2025 rates (LPG ≈ ₹900/cylinder, electricity ≈ ₹8/unit), induction cooking costs approximately ₹430–₹575/month versus LPG at ₹720–₹950/month for a family of 4. Induction is typically 30–40% cheaper. However, induction requires purchasing compatible flat-bottomed steel or iron cookware (not aluminium), which has an initial cost of ₹2,000–₹5,000 for a full set.
Q:Can I use my existing LPG cooktop cookware on an induction stove?
Only if your existing cookware is made of ferrous (magnetic) material. Steel pressure cookers and iron kadais typically work on induction. Aluminium vessels, copper-bottomed pans, and glass cookware do NOT work on induction. A simple test: if a fridge magnet sticks firmly to the base of your vessel, it will work on induction. Most Indian households need to replace their aluminium cookers and non-stick kadais when switching to induction.
