Induction Cooktop Electricity Cost Calculator

See how many units your induction stove uses and what it costs per day and month for your cooking habits.

🍳 It doesn't run at full watts the whole time. An induction cooktop cycles power to hold heat, so a 1800 W stove averages far less. The heat setting and cooking time decide the real cost.
On the label — usually 1200–2100 W
Full boil ~100, simmer ~40

💡 Cook for less: a flat induction pan that covers the coil, a lid while heating, and the lowest workable setting can cut this by 20–30%.
Formula: Units/day = Power (kW) × Hours × Heat-setting%  |  Cost = Units × Tariff (₹/unit)

How This Calculator Works

An induction cooktop's nameplate wattage is its maximum. In real cooking it modulates power up and down, so the average draw is lower — captured here by the heat-setting percentage.

Units = rated kW × cooking hours × average heat setting. Lower the setting and the units fall proportionally.

💡 Cook Cheaper

  • → Use a flat pan that covers the coil
  • → Keep a lid on while heating
  • → Use the lowest workable setting
  • → Switch off early, use residual heat
  • → Pre-soak dal/rice to cook faster

How Induction Cooktop Electricity Use Is Calculated

An induction cooktop's rating (say 1800 W) is the maximum it can draw. During cooking it pulses on and off to maintain the chosen heat level, so the average power is lower. We capture that with an average heat-setting percentage — full boil is near 100%, a simmer nearer 40%.

Units per Day = Rated Power (kW) × Cooking Hours × (Heat Setting % ÷ 100) Cost per Day (₹) = Units per Day × Tariff (₹/unit) Cost per Month (₹) = Cost per Day × Days Used

Worked Example — 1800 W, 1.5 hrs/day

1800 W = 1.8 kW  |  1.5 hrs/day  |  75% avg setting  |  30 days  |  ₹8/unit

Units/day = 1.8 × 1.5 × 0.75 = 2.03 units
Cost/day = 2.03 × ₹8 = ₹16.2/day
Cost/month = ₹16.2 × 30 = ₹486/month

Frequently Asked Questions

It is rated 1200–2100 W but rarely runs at full power because it cycles to hold temperature. On average it draws 60–80% of its rating, so an 1800 W cooktop uses ~1.1–1.4 units/hour — about ₹9–11/hour at ₹8/unit.

About 1.5 hours/day on an 1800 W cooktop at 75% load uses ~2 units/day — about ₹16/day or ₹486/month at ₹8/unit. Lighter cooking (45 min/day) costs around ₹240/month.

They are close. Induction is ~85% efficient versus ~40% for an LPG flame, so it wastes less heat. At ₹8/unit and ₹900 per 14.2 kg cylinder the cost per meal is similar — induction is often slightly cheaper for boiling and slightly costlier for long slow cooking, and wins on safety and speed.

Yes. The cooktop modulates power to the setting, so a simmer draws far fewer watts than a boil. Cooking on lower settings, using a lid, and matching the pan to the coil all cut the units used.

Use a flat induction pan covering the coil, keep a lid on, cook on the lowest workable setting, switch off early to use residual heat, and pre-soak dal/rice. These can cut cooking electricity by 20–30%.
