Three reproducible electric-oven scenarios
| Scenario | Published inputs | Active per session | Annual energy | Annual cost |
|---|---|---|---|---|
| 1.2 kWh for two cooking sessions per week | 1.2 kWh/session; 2 sessions/week; 2 W standby for 24 h/day; $0.18/kWh | 1.200 kWh/use · $0.22/use | 142.663 kWh | $25.68 |
| 2.0 kWh for four cooking sessions per week | 2.0 kWh/session; 4 sessions/week; 2 W standby for 24 h/day; $0.18/kWh | 2.000 kWh/use · $0.36/use | 434.663 kWh | $78.24 |
| 3.2 kWh for seven cooking sessions per week | 3.2 kWh/session; 7 sessions/week; 2 W standby for 24 h/day; $0.18/kWh | 3.200 kWh/use · $0.58/use | 1,185.520 kWh | $213.39 |
$0.18/kWh is an illustrative comparison rate, not a national or current market price. Cost per session is active electricity only; annual standby is not allocated across sessions.
Preheat, cycling, and measurement
Oven size, temperature, preheat, fan mode, door opening, cookware, batch size, and duration affect consumption. Thermostat cycling means rated power multiplied by elapsed time can overstate energy. A representative full-session kWh measurement or applicable model-specific energy label is preferable.
A watts-per-use estimate is available when representative electrical input, runtime, and duty cycle are known. It remains an estimate and must include preheating when the cooking session includes it. Standby displays and controls are measured or entered separately.
Electric-only scope and safety
Gas ovens and gas costs are outside this calculator’s scope. The site compares electricity only and does not claim that different appliances deliver equal cooking outcomes.
