How Much Does It Cost to Run a Coffee Maker?
About 2-5 cents a day, or roughly $1.44 per month for a typical 900W drip maker brewing one pot a day. At the 2024 US average rate of $0.16/kWh, the 10-minute brew uses 0.15 kWh (about $0.02) — but leave the warming plate on for 2 hours and the day's total roughly doubles to 0.30 kWh. That keep-warm plate, not the brewing, is where the real cost hides.
US average is $0.16/kWh.
A drip warming plate draws 70-80W. Pod tanks and espresso boilers idle hot too, but don't print the figure — measure yours with a plug-in monitor.

Your habit
0.30 kWh a day, every day
Keeping coffee hot is 50% of your daily energy — $8.76 a year. Pour into an insulated carafe and switch the machine off and that goes to zero, leaving just $8.76 for the coffee itself.
Push the wattage up and watch how little the annual figure moves; drag the keep-hot hours and watch it climb. That is the whole story of this appliance — a brew is a ten-minute burst, and a warming plate runs all morning at a tenth of the power but sixty times the runtime. Figures assume the machine draws its full brew wattage for the whole cycle and nothing at all once it is switched off.
Prefilled with the typical drip maker below. Change the wattage, the number of brew cycles, and how long the plate stays on — or check your state's electricity rate first.
How much electricity does a coffee maker use?
Daily cost = (watts ÷ 1,000) × hours running × price per kWh
A coffee maker has two phases that each count: a short, high-wattage brew and a long, low-wattage keep-warm. The brew is over in about 10 minutes; the warming plate can run for hours, and at ~75W it adds up to about as much energy as the brew itself.
Worked example (900W brew + 75W plate for 2h, $0.16/kWh): (0.9 kW × 0.17 h) + (0.075 kW × 2 h) = 0.30 kWh × $0.16 = $0.05 per day — or $1.44/month, $18/year.
How much does it cost to brew coffee daily?
One pot is one brew either way — what changes the bill is how long the warming plate stays on afterward. All rows are a 900W drip maker at $0.16/kWh.
| Daily habit | kWh per day | Cost per day | Cost per month | Cost per year |
|---|---|---|---|---|
| Brew only, switch off — Thermal carafe or pour-and-go | 0.15 | $0.02 | $0.72 | $9 |
| Brew + 1h warming plate | 0.22 | $0.04 | $1.08 | $13 |
| Brew + 2h warming plate (typical) | 0.30 | $0.05 | $1.44 | $18 |
| Brew + 4h warming plate — Plate left on | 0.45 | $0.07 | $2.16 | $26 |
| Two pots, 2h plate each — Heavy household | 0.60 | $0.10 | $2.88 | $35 |
Notice that the brew never changes: every row buys the same pot of coffee for the same 0.15kWh. Brew-only is a third of the "4-hour plate" row, and the whole difference is plate time — the warming plate, not the coffee, is the lever you control.
Drip vs. pod vs. espresso machine energy costs
Brew wattage is only half the story — what really separates these machines is how much energy they spend staying hot. Typical daily kWh below assumes a couple of cups a day at $0.16/kWh.
| Machine type | Brew watts | kWh per day | Cost per year | Where the energy goes |
|---|---|---|---|---|
| Drip (auto, warming plate) (typical) | 900W | 0.30 | $18 | Plate is ~half the daily energy |
| Drip (thermal carafe) | 900W | 0.15 | $9 | No plate — carafe holds the heat |
| Single-serve pod (Keurig-style) | 1,400W | 0.12 | $7 | Fast per-cup brew; reheats the tank |
| Semi-automatic espresso | 1,300W | 0.30 | $18 | Boiler heats up, then idles hot |
| Super-automatic espresso | 1,400W | 0.45 | $26 | Stays hot all day, grinds per shot |
Daily kWh for pod and espresso machines depends heavily on whether you leave them powered on. Switched fully off between uses, all five land near the brew-only figure — the spread above is mostly idle and keep-warm heating.

Even in a high-rate state, a daily pot is a rounding error on the power bill — but the warming-plate column shows how an everyday habit quietly adds up over a year.
What Drives the Cost
The warming plate, not the brew
Brewing is a 10-minute burst — about 0.15 kWh. The keep-warm plate sips just ~75W, but it can run for hours, and 2 hours of warming (0.15 kWh) matches the entire brew. Over a year that plate alone is roughly $9— about half the machine's total running cost, spent reheating coffee you may not even drink.
Staying hot vs. brewing hot
Pod and espresso machines barely cost anything to brew — the draw is over in seconds. The expense is the internal tank or boiler they keep at temperature so they're instant-ready. An espresso machine left on all morning can use more than a drip maker; switched off between cups, it's one of the cheapest.
It's pennies either way
Put it in perspective: a full year of daily coffee costs about $18 in electricity. An Energy Star fridge gets through $64 over the same year — so your whole year of coffee costs roughly what the fridge costs in 3 months, and the fridge never switches off. The coffee maker is one of the cheapest appliances in the kitchen to run, so the savings here are small in dollars but easy wins in habit.
Your electricity rate
The same pot costs three times as much in Hawaii (~$0.40/kWh) as in a low-rate state (~$0.11/kWh). It's still cents per day, but it's the one variable that shifts every appliance on your bill — check your state's average rate before trusting any single number.
How to Lower the Cost
Pour into an insulated carafe
Decant the pot and switch the machine off. A vacuum carafe holds heat 4-6 hours on zero watts — and kills the warming plate, your biggest line item.
Shorten the auto-off timer
Many programmable makers default to a 2-hour keep-warm. Set it to 0-30 minutes so the plate isn't cooking an empty pot all morning.
Switch espresso machines off between cups
The boiler's idle heating is the cost, not the shot. If you only drink twice a day, don't leave it warming for hours in between.
Right-size the brew
Brewing a full pot for one cup means more plate time keeping the rest warm. Make what you'll drink, or use a single-serve machine for solo cups.
Recommended picks
Coffee Gear That Skips the Warming-Plate Cost
The coffee maker is already cheap to run — the only real waste is the keep-warm plate and the idle heating on pod and espresso machines. These picks let your coffee stay hot without staying plugged in.
Thermal Carafe Drip Maker
No warming plate at all
A double-wall stainless carafe holds heat for hours, so the machine shuts off right after brewing — cutting out the 70-80W warming plate that quietly doubles a drip maker's daily energy.
Programmable Maker with Auto-Off
Plate can't run all morning
A short auto-off timer (many default to 2 hours) stops the warming plate cooking your coffee — and your bill — long after the pot's gone cold. Look for a 0-30 minute setting.
Insulated Travel Carafe / Mug
Keep heat without watts
Pour the pot into a vacuum carafe and switch the machine off. Coffee stays hot 4-6 hours on zero electricity — the cheapest possible way to keep a second cup warm.
Smart Plug Energy Monitor
Measure pod & espresso idle
Pod and espresso machines spend most of their energy staying hot, not brewing. A plug-in monitor shows the real idle draw — and a timer plug can cut power when nobody's pouring.

Frequently Asked Questions
How much does it cost to run a coffee maker?
A typical 900W drip coffee maker uses about 0.15 kWh to brew a pot — roughly $0.02 at the 2024 US average rate of $0.16/kWh. Leave the warming plate on for 2 hours and the day's total roughly doubles to about 0.30 kWh, or $0.05. Brewing one pot a day works out to roughly $1.44 a month and $18 a year — pennies a day either way.
Does leaving the warming plate on use a lot of electricity?
For a single appliance, yes — it's the surprise of the coffee maker. The keep-warm plate draws about 75W, so 2 hours of warming uses 0.15 kWh, almost exactly as much as the 10-minute brew itself. Over a year of daily use, the plate alone adds about $9 — roughly half your coffee maker's total bill. Pouring the pot into an insulated carafe and switching the machine off eliminates it entirely.
Are pod machines (Keurig) cheaper to run than drip?
Per cup, they're close. A pod machine draws more watts (around 1,400W) but brews in under a minute and has no warming plate, so the brew itself is cheap. The catch is the internal hot-water tank: if you leave the machine powered on all day it keeps that tank warm, which can quietly use more than a quick drip brew. Switched off between uses, a pod machine is one of the cheapest ways to make a single cup.
Do espresso machines cost more to run?
Usually, but not because of brewing — it's the boiler. A semi-automatic or super-automatic espresso machine heats a boiler to temperature and then idles hot so it's ready on demand. That standby heating, plus an auto-on schedule, is where most of the energy goes. Pulling a shot is seconds of draw; leaving the machine on for hours is what runs up the cost. Switching it off when you're done is the single biggest saving.
Is a coffee maker cheaper than a microwave or kettle for hot water?
For a single cup, the microwave usually edges it — heating one mug for ~2 minutes uses about 0.04 kWh, less than running a whole 0.15 kWh drip brew. But when you make a full pot, drip wins per cup: that 0.15 kWh spread across a 12-cup pot is barely 0.01 kWh per cup. Either way you're talking fractions of a cent — the appliance you use matters far less than whether you leave it switched on afterward.
How much does a coffee maker cost per month and per year?
At the US average rate, a 900W drip maker brewing one pot a day with a 2-hour warming plate costs about $1.44 a month and $18 a year. Skip the warming plate and it drops to about $0.72/month and $9/year. A two-pot household leaving the plate on lands closer to $35/year. It's one of the cheapest appliances in the kitchen to run.
