How we worked it out

  1. Energy per hour: 300 W ÷ 1,000 = 0.3 kWh
  2. Cost per hour: 0.3 kWh × $0.175 = $0.053
  3. Cost per day: × 0.3 hours = $0.016
  4. Month and year: × 30 days = $0.473, × 365 days = $5.75

About electric drill running costs

Corded electric drills draw power only while the motor runs. Battery models need charging-energy estimates instead.

Typical sizes: 300 W, 500 W, 700 W, 1,000 W.

How to spend less: Use the right bit and speed to avoid wasting time and energy.

What this estimate assumes

  • The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
  • Wattage is the typical label value, not a measured value. Check the label on your own appliance.
  • The rate is an approximate residential average. 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.
