LPG vs PNG vs Induction Cost Calculator

In most Indian cities, PNG (piped natural gas) is cheaper than LPG cylinders. At typical rates of ₹52/SCM for PNG and ₹900 per LPG cylinder, a family of 3–4 people pays roughly ₹468/month on PNG versus ₹1,350/month on LPG — saving over ₹10,500 per year. PNG also has no cylinder booking hassle and continuous supply, making it the preferred choice where available.

A typical Indian family of 3–4 people uses approximately 1 to 1.5 LPG cylinders (14.2 kg each) per month, depending on cooking habits. A 14.2 kg cylinder provides roughly 10–12 cooking days for a family of four cooking 2–3 meals daily. Heavy cooking or larger families can consume up to 2 cylinders per month.

Induction cooking is often significantly cheaper than LPG and even PNG, depending on local electricity rates. At ₹7.5/unit, a family of 3–4 using ~22 units/month spends just ₹165 for cooking electricity — versus ₹1,350 for LPG. Induction is also more energy-efficient (90% vs 65% for gas stoves) and has no open flame, making it safer indoors. The one-time cooktop cost typically pays for itself within 1–3 months when switching from LPG.

LPG cylinder prices in India vary by city and are revised monthly by oil marketing companies (IOC, BPCL, HPCL). As of 2025, a 14.2 kg domestic LPG cylinder costs approximately ₹800–₹950 in major cities. Delhi typically sees rates around ₹800–₹850, while other cities may be slightly higher. Check the official Indane, HP Gas, or Bharat Gas websites for your city's current price.

The break-even period depends on your monthly savings. If induction costs ₹165/month versus LPG at ₹1,350/month, your monthly saving is ₹1,185. With a cooktop costing ₹3,000, you break even in just 3 months. This calculator computes your personalized break-even based on actual usage, your local electricity rate, and the cooktop cost you enter.
