Quick answer: A typical 1800-2000 watt induction cooktop used for 1 hour a day costs roughly $0.22-$0.27 per day, $6.60-$8.10 per month, or $79-$97 per year in the US (at the 2026 average rate of $0.13/kWh). In India, the same usage costs about Rs.9-11 per day, or Rs.270-330 per month, at Rs.8/unit. Induction is generally 10-15% cheaper to run than a traditional gas or ceramic electric cooktop for the same cooking task, because almost all the energy goes directly into the pan instead of heating the surrounding air.
Induction Cooktop Running Cost Calculator
How the Calculation Works
Induction cooktops list their power draw in watts, usually 1200-3000W depending on the model and heat setting. The formula behind the calculator above is simple:
Energy (kWh) = Wattage / 1000 x Hours Used
Cost = Energy (kWh) x Electricity Rate
Unlike a gas burner or a coil electric hob, an induction cooktop only draws its rated wattage while actively heating – it does not waste energy warming the air around the pan. Most home cooks run a single burner at 1500-1800W for searing and boiling, and closer to 800-1200W for simmering, so real-world costs are often a little lower than the “maximum wattage” printed on the box.
Typical Induction Cooktop Wattage by Burner Size
| Burner Type | Typical Wattage | Common Use |
|---|---|---|
| Small burner | 1200-1400W | Simmering, small pans |
| Standard burner | 1800-2100W | Everyday cooking, boiling |
| Power/Boost burner | 2600-3000W | Fast boiling, wok cooking |
| Portable single-burner | 1000-1800W | Countertop, hostel/dorm use |
Worked Examples
| Scenario | Wattage | Daily Use | Monthly Cost (US, $0.13/kWh) |
|---|---|---|---|
| Light user, one meal a day | 1800W | 0.5 hr | $3.51 |
| Average household | 1800W | 1 hr | $7.02 |
| Heavy cook, two burners | 3200W combined | 1.5 hr | $18.72 |
| Portable single burner | 1200W | 1 hr | $4.68 |
Induction vs Gas vs Ceramic Electric: Cost Comparison
| Cooktop Type | Energy Efficiency | Relative Monthly Cost* |
|---|---|---|
| Induction | ~85-90% | Baseline (lowest) |
| Ceramic/coil electric | ~65-70% | 15-25% higher |
| Gas burner (cost in gas, not electricity) | ~35-40% | Varies with LPG/piped gas price |
*For the same amount of food cooked, assuming identical usage patterns. Actual savings depend on your local electricity and gas prices.
Tips to Reduce Induction Cooktop Running Costs
- Use flat-bottomed, induction-compatible cookware – warped pans lose contact and waste energy.
- Match the pan size to the burner ring; an undersized pan wastes heat.
- Use lids while boiling or simmering to cut cooking time significantly.
- Switch off the burner a couple of minutes before food is done – residual heat finishes the job.
- Cook in batches on one burner instead of running two burners for small quantities.
Frequently Asked Questions
Is induction cooking cheaper than gas?
It depends on local energy prices, but induction is usually more energy-efficient (85-90% vs 35-40% for gas), so if electricity and gas are priced similarly per unit of energy, induction often works out cheaper or comparable, especially where gas cylinder/piped gas prices are high.
How many units of electricity does an induction cooktop use per hour?
A standard 1800W induction cooktop uses about 1.8 units (kWh) per hour at full power. Most cooking is done at partial power, so actual usage is often 0.8-1.5 units per hour of active cooking.
Does induction cooking use less electricity than a microwave?
For similar-sized meals, induction and microwave energy use is often comparable, but it depends heavily on cook time and wattage. Microwaves usually win for reheating small portions; induction wins for larger pots and pans.
Why is my induction cooktop bill higher than expected?
Check for non-compatible cookware (thin or warped pans force the cooktop to work harder), using boost mode frequently, or leaving the cooktop on standby with a bright display for long periods.
Does the size of the pan affect running cost?
Yes. A pan smaller than the burner ring wastes energy because part of the induction field has nothing to heat. Always match pan diameter to the ring size marked on the cooktop.
Is a portable induction cooktop cheaper to run than a built-in one?
Wattage is the main factor, not portability. A portable 1200-1800W single burner typically costs less per hour than a built-in cooktop’s power burner (2600-3000W), simply because it draws less power.
How much does induction cooking cost per month for a family of four?
Using two burners for about 1.5 hours combined per day at 1800W each and $0.13/kWh, expect roughly $15-20 per month, though this varies with cooking habits and local rates.
Does standby mode use electricity?
Yes, but a negligible amount – typically 1-3 watts for the display and touch controls when idle, adding well under $1 per year to your bill.
Induction cooktops are one of the most energy-efficient ways to cook at home, and the running cost calculator above makes it easy to see exactly what your kitchen habits are costing you – whether you are comparing it to your old electric coil hob, planning a kitchen upgrade, or just curious where your electricity bill is going. Plug in your cooktop’s wattage and your local rate to get a number you can trust, then use the tips above to trim it further.
