Induction and gas cooktop running costs depend on local utility rates, cooking habits, and how efficiently each system transfers heat to food. At typical U.S. prices, gas often costs less per unit of useful cooking heat, but the gap can narrow or reverse where electricity is inexpensive and gas is costly.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Induction energy per 1 million BTU of useful heat | $45 | $56 | $69 | Assumes 85% efficiency and electricity at $0.13-$0.20 per kWh |
| Gas energy per 1 million BTU of useful heat | $28 | $38 | $50 | Assumes 40% efficiency and gas at $1.10-$2.00 per therm |
| Illustrative annual energy bill | $45 | $56 induction / $38 gas | $69 | Uses 1 million BTU of useful heat per year |
Assumptions: illustrative U.S. utility-rate ranges; actual bills depend on provider charges, taxes, and household use.
Typical induction and gas costs per useful cooking heat
For a fair comparison, the estimates above measure the fuel needed to deliver the same amount of heat to cookware. Induction transfers about 85% of its energy to the pan, while a typical gas burner transfers about 40%; appliance design and cooking conditions affect both figures.
At common U.S. rates, gas can cost about $28-$50 and induction about $45-$69 per 1 million BTU of useful heat. Those figures are energy-only estimates, not monthly bills or appliance purchase prices. On the example annual use of 1 million useful BTU, the average difference is about $18 per year, with gas lower.
How electricity and gas charges shape each cooktop bill
Electricity is billed by kilowatt-hour, while residential natural gas is commonly priced per therm. One therm contains 100,000 BTU before burner losses. The table converts both fuels to the cost of delivering 1 million BTU of useful cooking heat, using the efficiency assumptions above.
| Cost component | Induction calculation | Gas calculation | Estimated cost |
|---|---|---|---|
| Energy needed | About 345 kWh | About 25 therms | Based on 1 million useful BTU |
| Low-rate utility charge | $0.13/kWh | $1.10/therm | $45 induction / $28 gas |
| Typical-rate utility charge | $0.16/kWh | $1.50/therm | $55 induction / $38 gas |
| High-rate utility charge | $0.20/kWh | $2.00/therm | $69 induction / $50 gas |
These simplified calculations exclude fixed monthly service charges, which may remain on a utility bill even if a gas cooktop is no longer used.
When electricity rates, gas prices, or efficiency change the result
The comparison can flip when local rates differ substantially from the assumptions. At $0.10 per kWh, induction costs about $35 per million useful BTU; at $0.25, it costs about $86. Gas costs about $28 at $1.10 per therm, but rises to about $63 at $2.50 per therm.
For these efficiency assumptions, induction and gas break even when electricity costs roughly 68% of the gas price per therm. For example, at $1.50 per therm, the break-even electricity rate is about $1.02 per kWh—well above typical residential rates. However, this simplified threshold can vary with burner efficiency, pan size, and utility pricing structure.
Burner output and cooking technique also matter. A 12,000-BTU gas burner running at full output for one hour uses 0.12 therm; an induction zone averaging 1.8 kW for the same period uses 1.8 kWh. Actual cooking usually involves cycling and lower settings, so those full-power examples do not represent a typical hour of daily use.
What 1 million BTU of annual cooking means in dollars
Annual use varies widely with household size and cooking frequency. At average assumed utility rates, each 1 million BTU of useful heat costs about $56 with induction or $38 with gas. A household using half that amount would spend roughly $28 or $19, respectively; one using twice that amount would spend about $112 or $76.
For a concrete rate-based example, a household using 345 kWh for induction cooking pays about $55 at $0.16 per kWh. A gas household using 25 therms pays about $38 at $1.50 per therm. These are cooking-energy estimates only, not total utility bills, and they assume equal useful heat.
Why regional utility rates create different cooktop comparisons
Electricity and gas prices vary by state, utility, and plan, so national averages can mislead. As a rough comparison, electricity rates 20% below the assumed $0.16 average reduce induction energy cost by about 20%; rates 25% above it raise the cost by about 25%. Apply the same percentage method to the gas rate used in the table.
Gas service may also include a fixed monthly charge. If a home keeps gas service for a furnace or water heater, that charge is not a cooktop operating cost. If switching removes the final gas appliance, the household may avoid some or all of the fixed fee, depending on the utility. Check the bill’s supply, delivery, and fixed charges before comparing.
Installation and cookware expenses are separate from running cost
Purchase and installation costs do not change the energy calculation, but they affect the total cost of switching. An induction cooktop may require compatible magnetic cookware and a suitable electrical circuit; electrical work can add several hundred dollars or more if an upgrade is needed. A gas replacement may require a gas connection, ventilation work, or code-related changes.
Compare upfront quotes separately from annual fuel savings. If the estimated energy difference is only about $18 per year under the average assumptions, a large installation premium may take many years to recover through lower operating bills. Existing wiring, gas piping, and cookware can materially change that payback.
Which controllable choices lower induction or gas expenses
Match pan diameter to the burner or induction zone, keep lids on when practical, and use the lowest setting that maintains the needed simmer. For gas, flames extending beyond the pan waste heat; for induction, using a flat, compatible pan improves contact. Avoid heating an oversized pan on a small zone.
Before replacing a functioning cooktop solely to reduce bills, calculate annual use at the household’s actual rates. Compare at least two installation quotes, ask whether electrical or gas work is included, and verify any fixed utility charges. Reducing wasted heat and checking the full bill often matters more than relying on a national average.
