The number that matters most is your own electricity rate. Rates range from under 11¢ per kWh in some regions to over 30¢ in others, so the same electric toothbrush dock charger can cost two or three times as much depending on where you live.

As a personal care device, the electric toothbrush dock charger sits in the middle of most household energy budgets. The number that moves your bill is total run time, so the usage hours in the calculator above matter as much as the wattage.
At 5 watts, the electric toothbrush dock charger is a low-power device, so its cost per hour is small. The annual total only becomes meaningful if it runs for many hours a day — which is exactly why long-running low-wattage devices are easy to overlook on a bill.
Over a full year this electric toothbrush dock charger uses about 1.8 kWh of electricity and is responsible for roughly 0.7 kg of CO₂ emissions on an average grid. Because it runs more or less year-round, even a small reduction in daily use carries straight through to a lower annual total.
To put the draw in everyday terms, one hour of running this electric toothbrush dock charger uses about as much electricity as charging a smartphone 1 time. It is a rough comparison, but it makes an abstract wattage figure easier to picture.
If this electric toothbrush dock charger is one you use daily, even small efficiency gains compound. Cutting its usage or wattage by 20% would save around $0.06 every year — money that an efficient replacement can recover over its lifetime.
