One of the most practical questions before switching to induction: what will it actually cost to run, day to day? Here's the physics behind the answer, not just a headline number.

Typical power draw

A single induction zone typically draws 1200W–2600W at full power, with a full four-zone 60cm cooktop capable of drawing up to roughly 7000W if every zone ran flat out simultaneously — in practice, most cooktops automatically manage total load across zones, so you rarely hit that theoretical peak in real cooking. A portable single-burner unit usually sits around 1400W–2000W.

Why induction is cheaper to run than the headline wattage suggests

Induction's rated wattage is often similar to — or even a little higher than — a comparable ceramic electric element, but because roughly 85–90% of that input energy transfers directly into the pan (versus roughly 65–75% for ceramic electric, with the rest lost heating the surrounding glass and air), induction uses meaningfully less total energy to complete the same cooking task, mainly by cooking faster and wasting less heat into the kitchen.

Induction vs gas running costs

This varies significantly by state and current electricity/gas tariffs, and household gas and electricity pricing has continued to shift through the mid-2020s — check your own retailer's current rates rather than relying on a fixed national number. Cooktop use is also a genuinely small fraction of most households' total energy bill either way (hot water, heating/cooling and refrigeration dominate), so the difference from switching cooktop type alone is usually modest in absolute dollar terms, even where induction wins per-meal.

Tips to reduce running costs further

• Match pan size to zone size — an undersized pan on a larger zone wastes unused capacity and heats less efficiently
• Use lids to trap heat and cut cook time, particularly for boiling and simmering
• Take advantage of induction's fast response — turn power down earlier than you would on gas, since heat output drops almost instantly rather than lingering
• If you're on a time-of-use electricity plan, batch-cook during off-peak windows where practical

Bottom line

Induction cooktops are generally the cheapest cooktop type to run per meal cooked among the common domestic options, thanks to fast heat transfer and minimal wasted energy — on top of the safety and cleaning benefits covered in our induction vs electric comparison.

How to work out your own cost in one minute

The arithmetic is simple, and doing it with your own numbers beats any national average. Energy used, in kilowatt-hours, is power in kilowatts multiplied by hours of use. Multiply that by your tariff:

Cost = (zone watts ÷ 1000) × hours × your c/kWh rate

Find your rate on your electricity bill — it's the usage charge in cents per kilowatt-hour, and across Australia it commonly sits somewhere between about 25c and 45c/kWh depending on your state, retailer and whether you're on a time-of-use plan. Then work an example. A 2,000W zone run for 30 minutes uses 2.0 × 0.5 = 1kWh. At 35c/kWh, that's 35 cents.

The catch that makes real bills much lower than people fear: you almost never run a zone at full power for the whole cook. Bringing a pot to the boil might take 4 minutes at full power, after which it simmers at perhaps 20% for 15 minutes. That's about 0.23kWh, or roughly 8 cents at 35c/kWh — not the 50 cents a naive "2kW for 20 minutes" estimate suggests.

These are indicative figures for comparison between cooking methods, not a quote — actual use depends on your pans, how tightly you lid your pots, and your tariff.

Where induction's efficiency advantage actually comes from

Induction's efficiency isn't marketing. Because the pan itself is the heating element, there's no intermediate step losing energy to the air. Gas loses the most: a flame heats the pan base but also spills heat up the sides and into the room, which is why a gas kitchen gets so much hotter to stand in. Radiant electric sits in between — it has to heat a coil, then the glass, then the pan, and each transfer loses something, plus the glass stays hot long after you switch off.

That last point is worth dwelling on, because it's where the everyday saving hides. On a radiant cooktop, the energy stored in the hot glass and element after you finish cooking is simply lost to the room. On induction the glass is only warm from contact with the pan, so there's far less to throw away. The same goes for the heat-up phase: induction reaches working temperature in seconds rather than minutes, so less energy goes into the period before you're actually cooking.

There's a knock-on benefit that doesn't show on the cooktop's own line of the bill. Because induction dumps much less waste heat into the kitchen, air conditioning works less hard during an Australian summer. In a small apartment cooking a hot dinner in February, that difference is noticeable.

What it costs compared with gas, in practice

Comparing fuels properly means comparing useful energy, not billed energy. A megajoule of gas that delivers 40% of its heat to the pan is doing less work than a kilowatt-hour of electricity delivering 85–90%. That's why induction can cost less per meal even where the per-unit price of gas looks cheaper than electricity.

For many Australian households there's a second, larger number in play: the gas daily supply charge. If the cooktop is your last gas appliance, switching to induction can let you disconnect gas entirely and stop paying that fixed charge — which in some cases exceeds the entire cost of the electricity used for cooking. Working out whether that applies to you is usually more financially significant than optimising cooking technique.

Solar, batteries and time-of-use tariffs

If you have rooftop solar, the calculation changes in your favour. Cooking during daylight on self-consumed solar costs you the feed-in tariff you gave up — typically far less than the retail rate you'd otherwise pay. For households that cook lunch at home, or do batch cooking on weekends, induction on solar is about as cheap as cooking gets. A gas cooktop can't use solar generation at all.

On a time-of-use tariff, the opposite risk applies: dinner usually falls squarely inside the expensive evening peak window. The saving levers there are unglamorous but real — cook in batches, use the smallest pan and zone that will do the job, and keep lids on so you can drop to a lower power level sooner.

Standby and idle draw

An induction cooktop uses a small amount of power when switched on but not cooking — running its controls, display and, briefly, its cooling fan after a hot session. This is on the order of a few watts, which is negligible next to actual cooking, and it does not scale meaningfully with how many zones the cooktop has. A 90cm five-zone model costs more to run than a 60cm four-zone one only to the extent that you actually use the extra zones. Buying a bigger cooktop does not quietly raise your standing electricity cost.

Frequently asked questions

Does a bigger cooktop cost more to run even when idle?

No — an inactive zone draws negligible standby power. Running cost is driven almost entirely by how many zones are actively heating and for how long, not by the cooktop's total capacity.

Does induction use less electricity than an air fryer or oven for the same meal?

It depends heavily on the specific meal and cook time — direct comparisons between appliance categories vary too much by recipe to state a single universal rule.

Will solar panels change whether induction is worth it?

If you have solar and cook mainly during daylight hours, induction's efficiency advantage compounds further against self-consumed solar power rather than imported grid electricity, improving the economics further for many households.

How much does it cost to boil a litre of water on induction?

Around 4 cents at a 35c/kWh tariff, using roughly 0.1kWh. Induction is close to an electric kettle for this task because both heat the water directly with little waste, and both comfortably beat gas, which loses a large share of its heat around the sides of the pot.

Will switching from gas to induction increase my electricity bill?

Yes — your electricity usage will rise, because you have moved a task from one fuel to another. The question that matters is your total energy cost. For most households the gas bill falls by more than the electricity bill rises, and if the cooktop was your last gas appliance you may also remove the gas daily supply charge entirely.

Do induction cooktops use a lot of power on standby?

No. Standby draw is a few watts for the control panel and display, which is trivial compared with cooking. If you want to eliminate it entirely you would need to isolate the circuit, which is not worth the inconvenience for the amount involved.

Is it cheaper to cook a meal on the cooktop or in the oven?

For small quantities, the cooktop almost always wins, because an oven has to heat a large insulated cavity before it starts cooking your food. Ovens become competitive when you are cooking enough food at once to justify heating that space — which is the real argument for batch cooking.

Does using a bigger pan cost more to run?

Slightly, because a larger pan over a larger zone draws more power and has more metal and more food to heat. The bigger effect is mismatch: a small pan on a large zone wastes energy that the coil cannot couple into. Matching pan size to zone size, and keeping lids on, saves more than pan size choice alone.
