Induction cooktops deliver 85 percent of input energy to the pan. Gas ranges deliver 40 percent. Water boil time: induction 3:48 vs gas 6:42 for the same pan. Per-meal cost: $0.18 induction vs $0.31 gas at current US average rates. 5-year cooking-cost savings: roughly $640 for a 1.5-meal-per-day household. Installation: $1,800 to $3,500 for an induction cooktop including 240V circuit if needed.
Boil time and efficiency
1 gallon water at room temp: induction boils in 3:48 on high. Gas boils in 6:42 on high. Electric resistance coil boils in 4:12.
Energy efficiency: induction 85 percent, gas 40 percent, electric coil 70 percent. Induction wins both speed and efficiency.
Install cost and 240V requirement
Induction cooktop cost: $1,200 to $2,800 for unit. Install with existing 240V: $300 to $600. New 240V circuit: $1,500 to $2,500 if no existing.
Total install: $1,800 to $5,000 depending on electrical work. IRA HEAR program covers up to $840 for income-qualified.
