Electric vs Gas Stove Cost: The Full Guide

The efficiency math, in plain terms

A stove does not sell you heat in the food; it sells you heat from a burner, and some of it never reaches the pan. The US Department of Energy puts that transfer efficiency at about 40% for gas, about 74% for an electric coil, and about 84% for induction. In other words, a gas burner throws away roughly 60% of its energy warming the kitchen air, while induction wastes only about 10%. That sounds like an open-and-shut case for induction, until you price the fuel. Gas at $1.60 per therm works out to about $0.055 per kilowatt-hour of heat, while residential electricity at $0.17 per kilowatt-hour costs roughly three times as much per unit. Efficiency tells you how much fuel you need; price tells you what that fuel costs. You need both: useful heat divided by efficiency gives input energy, and input energy times price gives the annual bill.

The default case, line by line

Start with a household that cooks 14 meals a week, two a day, and assume each cooked meal needs 0.50 kilowatt-hours of heat actually delivered to the food. Over a year that is 14 times 52 times 0.50, or 364 kilowatt-hours of useful heat. The gas stove must burn 364 divided by 0.40, which is 910 kilowatt-hours of gas energy, equal to 31.05 therms at 29.307 kilowatt-hours per therm, costing $49.68 at $1.60 per therm. The coil stove needs 364 divided by 0.74, or 491.89 kilowatt-hours, costing $83.62 at $0.17 per kilowatt-hour. Induction needs 364 divided by 0.84, or 433.33 kilowatt-hours, costing $73.67. So gas beats induction by $23.99 a year and beats coil by $33.94, while induction beats coil by $9.95. What did not matter: wattage rating, brand, or burner size. Only efficiency, fuel price, and how much you cook enter the bill.

When cheap electricity flips the winner

Change one price and the ranking changes. At $0.10 per kilowatt-hour, the kind of price found in hydro-powered regions, induction falls to $43.33 a year and coil to $49.19, while gas, untouched by the power price, stays at $49.68. Induction is now the cheapest stove to run, saving $6.35 a year against gas, and even the humble coil stove edges gas by a few cents. Cheap electricity rewards efficiency: the stove that wastes least wins, and the usual “gas is cheaper” advice is simply wrong where power stays cheap.

When expensive gas flips the winner

The mirror image works too. Raise gas to $2.50 per therm, a price some regions already pay, and the gas bill jumps to $77.63 a year, while coil stays at $83.62 and induction at $73.67. Induction is cheapest again, this time saving $3.96 a year against gas, and the margin would widen further if gas rose more. Expensive gas punishes the wasteful burner hardest, because every unit of heat thrown away into the kitchen was bought at the high price. Together the branches give a simple rule: gas wins when gas is cheap and power is dear, induction wins when either price moves against gas, and coil almost never wins. Coil survives on purchase price, not running cost.

The payback question, answered honestly

Induction stoves cost more to buy, so the natural question is whether the savings repay the premium. Against a coil stove at the default prices, induction saves $9.95 a year, so a $300 premium takes about 30.1 years on unrounded figures, to repay — roughly the life of the stove itself. Against gas at the defaults, there is no payback at all, because induction costs $23.99 a year more to run than gas, so the premium only grows. Heavy cooks do better: at 28 meals a week every figure doubles, to $99.36 for gas, $167.24 for coil, and $147.33 for induction, and the induction-versus-coil saving doubles to $19.91 a year, cutting the payback to about 15 years. Even then, payback is a weak reason to buy induction: buy it for speed and control, and treat any energy saving as a bonus at the right prices.

Beyond the bill: speed, control, and air

The energy bill is the smallest part of living with a stove, and the other parts mostly favor induction. It boils water roughly twice as fast as gas, and its heat responds instantly to the dial and stops when the pan lifts. Gas keeps two genuine advantages: it works during a power outage, since most burners light with a match, and many cooks prefer an open flame for wok cooking and charring. Coil keeps one: it is cheap and it works with any pan. On indoor air, gas is the outlier, releasing nitrogen dioxide and other combustion byproducts into the kitchen with every meal, which is why a range hood that vents outside matters far more over a gas stove than over an electric one. Against a bill difference of about $24 a year at average prices, pick the stove you like cooking on and let the bill follow.

Three common mistakes

Mistake one: comparing efficiency instead of cost. Induction at 84% against gas at 40% looks like a rout, but fuel prices reverse it at average rates. Always multiply efficiency by your local prices before concluding anything. Mistake two: using national average prices for a local decision. Averages hide the $0.10 power regions where induction wins and the $2.50 gas regions where it wins again; your bill, not the national bill, is the one you pay. Read both prices off your own utility bills before deciding. Mistake three: buying induction to save money against gas. At average prices induction costs more to run than gas, so a premium paid for savings is a premium lost. Buy induction for speed, control, and clean air, and buy gas if cheap fuel and outage-proof cooking matter most to you.

The bottom line

At 14 meals a week and average prices, gas costs $49.68 a year, coil $83.62, and induction $73.67. Cheap power or dear gas hands the win to induction, heavy cooking doubles every figure without changing the ranking, and a $300 induction premium takes 30.1 years to repay against coil and never repays against gas. Run your own prices through the electric vs gas stove calculator, read your actual utility bills, and choose the stove you will enjoy cooking on — the energy bill, whichever way it falls, is smaller than the argument about it.
