Work out fridge energy cost instantly with clear inputs, formula shown and shareable results.
A fridge freezer runs continuously, so its modest power draw accumulates into one of the larger appliance loads in a home. Efficiency has improved dramatically — a fifteen year old unit can use twice the electricity of a new one — but replacement payback is still usually a decade.
Fridge cost
annual cost = annual kWh x tariff; replacement saving = (old kWh - new kWh) x tariff
Roughly, but ambient temperature and how full the appliance is both matter. A fridge in a warm kitchen or garage uses noticeably more.
Cleaning the condenser coils, checking the door seal and leaving a gap behind the unit for airflow. All are free and can cut consumption by 10-15%.
