How Much Does It Cost to Run a Coffee Maker? $0.15/Hr, $1.84/Mo

Running a coffee maker at 900 watts for 0.4 hours a day costs about $0.06 a day and $1.84 a month at 17¢/kWh, the EIA 2025 annual US average (July 2026 monthly: 18.31¢) — roughly $22 a year.

The same a coffee maker at 0.4 hours a day costs $1.30 a month at 12¢ and $4.86 at 45¢ — usage held constant, only the rate moving:

Why this number

Running a coffee maker at 900 watts for 0.4 hours a day costs about $0.06 a day and $1.84 a month at 17¢/kWh, the EIA 2025 annual US average (July 2026 monthly: 18.31¢) — roughly $22 a year. The formula for a coffee maker: 900 W ÷ 1,000 × hours × your rate per kWh. For a coffee maker your own rate changes the answer: at 12¢/kWh that month costs $1.30, at 45¢/kWh it costs $4.86.

A coffee maker rated at 900 watts, run 0.4 hours a day, costs about $0.06 a day — about $1.84 a month, or $22 a year — at the US average electricity rate of 17¢/kWh. That places it 33th of the 40 appliances tracked here, near the bottom. It is not where a high bill comes from, and switching it off will not rescue one.

What actually drives this number

Brewing is brief and cheap; the warming plate is where cost quietly accumulates if it stays on for hours. A thermal carafe removes that entirely.

What about an electric kettle? Same appliance class, same answer. A kettle is a resistance element in water, so energy per boil is set by physics, not the brand: heating one litre from tap temperature to boiling takes about 0.09-0.10 kWh (1 kg × ~80°C rise × 4.186 J/g°C), a cent and a half at the US average rate. Boil twice a day and a kettle lands within pennies of the coffee maker above — which is why it does not get its own page.

At 900 W every hour of this load costs about $0.15, and no more efficient unit exists to buy — resistance heat is resistance heat at any price point. At this scale the levers are habit-sized, not equipment-sized: its closest heat-category neighbor on a monthly bill is the hair dryer at about $1.91, and the electricity cost calculator prices any wattage-and-hours pattern at your own rate.

Where this number comes from

• Benchmark: 130 kWh/year — Merced ID’s appliance table rates a 1,000 W coffee maker at 0.25 kWh per use
• Assumed use for a coffee maker: 0.4 h/day, 30 days/month, 12 months/year — every one of these is editable in the calculator above
• Rate for a coffee maker: 17¢/kWh, the EIA 2025 annual US average (July 2026 monthly: 18.31¢), from EIA Electric Power Monthly, Table 5.6.A ; the state selector above fills in yours

Putting Coffee maker in proportion

At 17¢/kWh, a coffee maker next to the rest of the bill:

• Coffee maker at $1.84 a month is close to Wi-Fi router and modem at $1.84, and just under Hair dryer at $1.91
• One hour of a coffee maker uses as much as 15 hours of a 60 W Wi-Fi router
• Over a year a coffee maker comes to $22 — about 0.1 months of a $150 monthly electricity bill

For a coffee maker: making heat is where household electricity goes, but how it is made decides the bill. A resistance element — an oven, a dryer, a resistance furnace, a kettle — converts every watt into exactly one watt of heat, so a cheap appliance and an expensive one with the same rating cost the same to run and efficiency is not something you can shop for. Equipment that moves heat instead of making it, like a heat pump, delivers several units of heat per unit of electricity and breaks that rule entirely. The only levers on a resistance load are running it less, running it lower, or heating a smaller space. On this site’s own numbers, a coffee maker lands at #33 of 40 on the monthly-cost ranking, at about $1.84 for a typical month.

The formula, in full

The 900 W arithmetic for a coffee maker, step by step:

1. Watts to kilowatts. 900 W ÷ 1,000 = 0.90 kW.
2. Energy per day. 0.90 kW × 0.4 hours = 0.36 kWh.
3. Cost per day. 0.36 kWh × $0.17 = $0.06.
4. Cost per month. $0.06 × 30 days = $1.84.

For a coffee maker the two levers are run-hours (0.4 h/day here) and your rate; used this briefly, even 900 W costs little — which is why anything that makes heat dominate the rankings.

Frequently asked questions

How we calculated this

Worked for a coffee maker: 900 W ÷ 1,000 × 0.4 h × $0.17 = $0.06 a day; × 30 days = $1.84 a month; × 12 months in use = $22 a year. 900 W and 0.4 h are the typical figures cited for a coffee maker; 17¢ is EIA’s 2025 annual US average.
