Brewing and warming are different
A drip coffee maker uses the most energy while heating water for brewing. After brewing, a warming plate may use less power but can still add cost if it stays on for hours.

A 1,000 watt coffee maker costs about $0.09 to run for 30 minutes at $0.17 per kWh.
Quick estimate
This uses 1000 watts, 0.5 hours per day, and an electricity rate of $0.17 per kWh.
Brewing uses the most power, while warming plates can add cost if left on.
Many coffee maker units fall around 1000 watts, with a rough range of 600 to 1500 watts. Check the product label, user manual, or manufacturer specifications for the most accurate number.
| Estimate | Watts | Hours per day | Daily cost | Monthly cost |
|---|---|---|---|---|
| Low estimate | 600W | 0.25 | $0.03 | $0.77 |
| Typical use | 1000W | 0.50 | $0.09 | $2.55 |
| High estimate | 1500W | 0.75 | $0.19 | $5.74 |
Convert watts to kilowatts, multiply by the number of hours used, then multiply by your electricity rate.
Cost = Watts / 1000 x Hours Used x Electricity Rate For this coffee maker example: 1000 / 1000 x 0.5 x 0.17 = $0.09 per day.
These details make this estimate more useful for real-world use.

Single-serve coffee makers usually run for short bursts, so each cup may use little energy. If the machine keeps water hot between cups, standby or ready mode can become part of the total daily use.
Turn off the warming plate or use an insulated carafe.
The easiest way to improve the estimate is to replace the default values with your actual wattage, average runtime, and local electricity rate.
