About electric toothbrush running costs

How to spend less: Use the manufacturer’s charger and consider standby draw only if you want a detailed annual estimate.

What this estimate assumes

  • Wattage is the typical label value, not a measured value. Check the label on your own appliance.
  • The rate is an approximate residential average in Montana. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
  • A month is 30 days and a year is 365 days.
