What drives the cost
A coffee maker draws around 900 watts while brewing, which takes only a few minutes. The bigger long-run cost is a warming plate left on for hours, which quietly consumes power to keep a pot hot and stale.

How to cut the cost
- Brew into an insulated carafe rather than leaving the warming plate on.
- Switch off the plate as soon as brewing finishes if your model doesn't auto-off.
- Brew only what you'll drink.

Questions
Does leaving a coffee maker on use much power?
The warming plate typically draws 50-100 watts continuously. Left on all morning it can use more energy than the brewing itself.
How do you calculate what a coffee maker costs to run?
Multiply its wattage by the hours it runs per day, divide by 1,000 to get kilowatt-hours, then multiply by your electricity rate. For a coffee maker: 900 W × 0.25 h ÷ 1,000 = 0.23 kWh per day, which at 19.4¢/kWh is $0.04 per day.
How many watts does a coffee maker use?
Typically 900 watts, with most models falling between 600 and 1,500 watts. The label on the appliance or its power supply gives the figure for your specific unit.
