Why the cost differs in District of Columbia
District of Columbia has the 42nd cheapest residential electricity of the 51 US states and territories we track, at 25.40¢ per kWh against a national average of 18.44¢. That is +37.7% compared with the national figure. The District is an entirely urban service territory with no generation of its own, so every kilowatt-hour arrives over transmission and the cost profile is dominated by distribution and delivery charges rather than fuel. Retail choice is available. Dense building stock means a high share of apartments, where cooling load per household is lower than the national norm but heating is often electric.
For this appliance specifically, the difference works out to an extra $0.32 a year over what the same printer would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $2.37 a year; in Idaho it would cost $0.56. That spread of $1.81 is entirely down to location.
District of Columbia sits above the national average, so the running cost of this printer is modestly higher than a typical US household would pay. Usage habits still matter more than location at this rate level.
Because District of Columbia has retail supplier choice, the state average blends many different contracted rates. If you have shopped for a plan, your own price per kWh is the number to put in the calculator.

About running a printer
Laser printers spike to several hundred watts during fusing but idle very low, so cost tracks pages printed rather than hours powered. Inkjets draw far less overall and have no fusing stage, though their consumables cost more.
What actually changes the cost
- Nameplate wattage is not running cost. This printer draws about 50W when active, but cycles roughly 50% of the time it is switched on, so effective consumption is near 25W.
- Models vary widely, from about 30W to 500W. Check the nameplate on your own unit rather than assuming an average, because the spread is more than 2x.
- If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.
How we worked this out
The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:
50W ÷ 1000 × 0.5h × 50% = 0.013 kWh/day × 25.40¢ = $0.003 per day
One honest caveat: District of Columbia’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.
Questions about printer running costs
How many watts does a printer use?
A typical printer draws about 50 watts while running, with most models falling between 30W and 500W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a printer use per day?
At around 0.5 hours of use a day and a 50% duty cycle, that works out to roughly 0.01 kWh per day, or about 0 kWh a month. Your actual figure depends on your usage and model.
Why does the cost differ so much between states?
Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same printer, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.
Is it cheaper to run a printer at night?
Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
