How Much Does It Cost to Run a House Per Month?

US households average $470–$610/month on utilities. See the real EIA-backed breakdown by state, home size, and which fixes actually lower the bill.

How Much Does It Cost to Run a House Per Month? The 2026 Breakdown

Most people know their mortgage or rent to the dollar and have only a vague sense of everything else. That everything else — electricity, gas, water, sewer, trash, internet — typically runs $470 to $610 per month for an average American household, which is $5,640 to $7,320 a year going out the door largely unexamined.

This guide breaks that number into its components using US Energy Information Administration data, shows how dramatically it varies by state and home size, and identifies which reduction strategies actually move the number versus which ones are mostly folklore. It also flags where the available data is genuinely solid and where published figures are modeled estimates rather than measured facts — a distinction most articles on this topic skip entirely.

The National Average

Published estimates for total monthly household utilities cluster in a range rather than converging on one figure:

Source EstimateMonthly TotalWhat It Includes
$470/month$5,640/yearElectricity, gas, water, internet (~$65), trash (~$30)
$610/month$7,320/yearBroader definition of essential utilities

The spread reflects definitional differences — whether internet, trash, streaming, and sewer are counted, and which year’s price data is used. Neither figure is wrong; they are measuring slightly different baskets.

The One Number That Is Genuinely Solid

The most reliable component figure available: the US Energy Information Administration reports the average US residential electric bill at approximately $144 per month in 2024. That is utility-reported grid consumption data rather than a modeled estimate, which makes it more dependable than most figures in this category.

A transparency note worth making Electricity and natural gas figures come from EIA utility-reported data and are solid. Water, sewer, and internet estimates in most published sources are modeled projections scaled to local cost-of-living indices — there is no authoritative national government dataset for residential water or internet pricing. Treat electricity figures as measured and water/internet figures as educated estimates.

Breaking Down the Monthly Bill

CategoryTypical Monthly RangeNotes
Electricity$120–$180Largest single utility for most households; EIA national average ~$144 (2024)
Natural gas$60–$130Highly seasonal; near zero in summer in many climates
Water and sewer$36–$60Sewer often costs more than the water itself
Internet$65–$100Rarely varies with usage; a fixed monthly commitment
Trash and recycling$25–$40Sometimes bundled into municipal taxes rather than billed

Electricity dominates, which is why almost every meaningful reduction strategy targets it. Internet is the second-largest for many households and is also the most negotiable — it is a contracted service with competing providers, unlike water or sewer.

State Variation: The Largest Factor You Cannot Control

Where you live affects this number more than almost any decision you make inside the house. Comparing EIA-anchored estimates for a standard 1,800 square foot, three-occupant home:

StateElectricity RateMonthly ConsumptionEst. ElectricEst. Total Utilities
Texas16.44¢/kWh1,096 kWh$180$405
Pennsylvania21.55¢/kWh817 kWh$176$360
New Jersey23.27¢/kWh662 kWh$154
New York29.93¢/kWh571 kWh$171
California33.25¢/kWh503 kWh$167$407

The Counterintuitive Pattern in That Table

Texas has the cheapest electricity rate on the list at 16.44 cents per kilowatt-hour and one of the highest electric bills at roughly $180 per month. California has the most expensive rate at 33.25 cents — more than double Texas — and a lower bill at roughly $167.

The reason is consumption, not price. Texas households average 1,096 kWh per month against California’s 503 kWh. Air conditioning load in a hot climate overwhelms the rate advantage entirely.

This matters practically: a cheap rate does not mean a cheap bill, and comparing states by rate alone is misleading. Consumption driven by climate and home size is frequently the larger variable.

Highest and Lowest Cost States

Hawaii ($730/month), Connecticut ($580), California ($540), and Massachusetts ($520) sit at the top of total utility costs, driven by expensive electricity, harsh climates, or both. Hawaii and Alaska rely heavily on imported fuel, which raises generation costs substantially. States with hydropower like Idaho enjoy notably low costs.

The West tends to run expensive overall — Hawaii, Alaska, California, and Oregon frequently rank near the top — due to geographic isolation, higher energy prices, infrastructure challenges, and environmental regulations.

How Home Size Changes the Number

Square footage drives heating and cooling load, which drives the largest utility line item.

Home TypeTypical Monthly UtilitiesPrimary Driver
Studio / 1-bedroom apartment$150–$250Small conditioned volume; shared building systems
2-bedroom apartment$200–$320Moderate load; often no separate water bill
1,200–1,500 sq ft house$320–$450Full responsibility for all utilities
1,800–2,200 sq ft house$400–$550Standard benchmark used in most estimates
2,500–3,500 sq ft house$500–$750HVAC load scales with conditioned volume
3,500+ sq ft house$700–$1,000+Often multiple HVAC zones

A useful mental model: the marginal cost of square footage is not linear with purchase price but is roughly linear with conditioned volume. Doubling house size does not double the mortgage in most markets, but it comes close to doubling heating and cooling cost.

What Actually Lowers the Bill

Ranked by return relative to effort and cost, based on where the money actually goes.

1. Thermostat Setpoint — Highest Return, Zero Cost

Heating and cooling is the largest share of the largest bill. Each degree of setpoint change produces a measurable reduction in HVAC runtime, and the change is free.

Practical version: a programmable or smart thermostat that reduces conditioning while the house is empty or occupants are asleep captures most of this benefit automatically. The mistake to avoid is aggressive setback in humid climates, where allowing indoor humidity to climb creates a different problem entirely.

2. Air Sealing Before Insulation

Homeowners typically think about insulation first, but air leakage around windows, doors, outlets, attic hatches, and penetrations frequently costs more than insufficient insulation depth. Caulk and weatherstripping cost under $50 and address the leaks directly.

The diagnostic worth doing: on a windy day, hold a lit incense stick near window frames, door frames, and outlets on exterior walls. Visible smoke deflection marks a leak worth sealing.

3. Water Heater Temperature

Water heating is typically the second-largest energy use in a home after space conditioning. Many water heaters ship set higher than necessary. Lowering the setpoint to 120°F reduces standby losses and the energy required per heating cycle, and also reduces scald risk.

4. Negotiate or Change Internet Service

Internet is often the second-largest line item and the only one genuinely negotiable. Promotional pricing expires and reverts to rack rate, frequently without the customer noticing. Calling to ask for current promotional pricing, or switching providers, commonly saves $20 to $40 per month — $240 to $480 annually for one phone call.

5. LED Conversion — Largely Already Done

Worth mentioning mainly to note that this advice has aged. Most households have already converted, and remaining incandescent bulbs are typically in low-use fixtures where the payback is slow. If you still have incandescent bulbs in high-use fixtures, converting is worthwhile; if not, this is no longer the lever it was a decade ago.

6. Laundry Temperature

The large majority of energy used by a washing machine goes to heating water, not to running the motor. Washing in cold water eliminates most of that, and modern detergents are formulated to work at cold temperatures.

7. Fix Leaks Promptly

A running toilet or dripping faucet wastes water continuously and silently. Toilet flappers are the most common culprit and cost a few dollars to replace. The diagnostic: add food coloring to the tank, wait twenty minutes without flushing, and check whether color appears in the bowl.

What Does Not Work As Well As Advertised

An honest section, because the energy-saving advice ecosystem contains a lot of low-value recommendations presented with the same confidence as high-value ones.

Unplugging Devices to Stop Phantom Load

Standby power draw is real but small for most modern electronics, which are subject to standby efficiency standards. The effort-to-savings ratio is poor compared to addressing HVAC. Exceptions worth targeting: older equipment, devices with external power bricks that stay warm, and anything with an always-on display.

Space Heaters as a Whole-House Strategy

Electric resistance heating is close to 100 percent efficient at converting electricity to heat, which sounds excellent — but electricity is an expensive way to buy heat compared to natural gas in most markets. Space heaters are cost-effective only for heating one occupied room while substantially lowering the whole-house setpoint. Running several simultaneously typically costs more than central heating.

Closing Vents in Unused Rooms

This intuitively should save money and frequently does the opposite. Central HVAC systems are designed for a specific duct pressure and airflow. Closing vents raises static pressure, which can reduce system efficiency, strain the blower, and in some cases cause coil freezing. The savings, if any, are small and the risk of expensive damage is real.

Solar Screens and Window Film Without Context

These help meaningfully on south and west-facing glass in hot climates and do very little on north-facing glass or in heating-dominated climates, where reducing winter solar gain is counterproductive. The blanket recommendation ignores orientation and climate, which are the variables that determine whether it works.

Where the Electricity Actually Goes

Knowing the total is less useful than knowing the distribution, because it tells you which appliances are worth attention and which are noise.

End UseApproximate Share of Home ElectricityPractical Implication
Heating and coolingLargest single share in most homesThermostat and air sealing are the highest-return actions
Water heatingSecond largest in many homesSetpoint reduction and shorter showers both matter
RefrigerationContinuous but moderateAge matters — a 20-year-old fridge can use double a new one
LightingSmall since LED adoptionNo longer a meaningful lever for most households
Laundry (washer and dryer)Moderate; dryer dominatesDryers are among the most energy-intensive appliances
Electronics and standbySmall and shrinkingLow return on effort to address

The Clothes Dryer Deserves Specific Mention

Electric dryers are among the highest-draw appliances in a typical home, and unlike heating and cooling, their use is entirely discretionary in timing and partially discretionary in frequency. Line drying even half of laundry loads produces a measurable reduction, and running full loads rather than partial ones improves efficiency per garment.

A frequently overlooked maintenance item: a clogged dryer vent extends drying cycles substantially, increasing both energy use and fire risk. Cleaning the vent duct — not just the lint screen — annually addresses both.

Refrigerator Age Is a Hidden Variable

Refrigerators run continuously, which makes efficiency differences compound. A refrigerator from the early 2000s can consume roughly double what a comparable current model uses. For households with a second refrigerator or freezer in a garage or basement — often an older unit kept for overflow — that appliance may be costing more annually than its replacement value justifies.

If You Rent Rather Than Own

Most utility advice assumes homeownership and the ability to modify the building. Renters face a different problem: the highest-return interventions are frequently outside their control.

What Renters Can Actually Control

Thermostat management, water heater temperature where accessible, laundry practices, and internet service negotiation are all available to renters and represent most of the achievable savings. Portable draft stoppers and removable weatherstripping address air leakage without permanent modification.

What to Clarify Before Signing

Electricity and internet are almost always tenant-paid. Apartments advertised as “utilities included” typically mean water and trash only. Always ask specifically which utilities are covered rather than assuming, because the difference between water-and-trash-included and all-inclusive is roughly $200 to $300 per month.

Two questions worth asking a landlord that most renters do not: what were the previous tenant’s average monthly bills, and what is the age of the HVAC system and water heater. Neither is confidential, both predict your costs better than the unit’s square footage, and a landlord’s reluctance to answer is itself informative.

The Older-Building Trap

Character-rich older buildings frequently have single-pane windows, minimal wall insulation, and aging heating systems. The rent may be attractive while the total monthly cost is not. When comparing units, comparing rent alone can be misleading by $150 or more per month.

Seasonal Variation: Why Averages Mislead

Monthly average figures conceal a pattern that matters for budgeting. In most US climates the bill is not flat across the year — it has two peaks, or one large one.

SeasonTypical PatternBudgeting Implication
Winter (Dec–Feb)Gas peaks; electricity moderateHighest bills in heating-dominated climates
Spring (Mar–May)Both lowLowest total bills of the year
Summer (Jun–Aug)Electricity peaks sharply; gas near zeroHighest bills in cooling-dominated climates
Fall (Sep–Nov)Both moderateSecond-lowest period

The practical consequence is that a household budgeting from a spring or fall bill will be surprised twice a year. Many utilities offer budget billing or level pay, which averages annual cost into equal monthly payments — this does not reduce total cost but eliminates the seasonal shock, which for tight budgets has real value.

A Realistic Annual Budget

For a 1,800 square foot home with three occupants in a moderate-cost state:

CategoryMonthlyAnnual
Electricity$155$1,860
Natural gas$80$960
Water and sewer$45$540
Internet$75$900
Trash and recycling$32$384
TOTAL$387$4,644

Against a household income at the US median, that represents a meaningful but manageable share. In high-cost states the same house could run $600 to $730 per month — $7,200 to $8,760 annually — which is the gap that makes relocation decisions financially consequential in ways buyers frequently underestimate.

A buyer moving from a mild climate to a hotter or colder market can see the largest jump in this category even when the mortgage payment looks comparable. Asking for twelve months of actual utility history on a specific home before purchase is one of the more useful and least common pieces of due diligence available.

Conclusion

Running a house costs the average American household $470 to $610 per month, with electricity the largest component at roughly $144 nationally per EIA data. The variation around that average is driven far more by state, climate, and home size than by household habits — Texas households consume more than double California’s electricity despite paying half the rate.

Within your control, the ranking is clear and narrower than most advice suggests. Thermostat setpoint and air sealing address heating and cooling, which is the largest share of the largest bill. Negotiating internet service is the easiest three-figure annual saving available. Water heater temperature and cold-water laundry are genuine but smaller. Most of the remaining advice — unplugging devices, closing vents, space heater strategies — ranges from marginal to actively counterproductive.

And the single most useful thing a prospective buyer can do costs nothing: ask the seller for a year of actual utility bills before committing to a house. No national average substitutes for the specific number that house produces.

Frequently Asked Questions

What is the average monthly utility bill in the US?

Estimates range from $470 to $610 per month depending on which utilities are counted. The most reliable single component is electricity, which the EIA reports averaged approximately $144 per month for US residential customers in 2024.

Which state has the most expensive utilities?

Hawaii at roughly $730 per month, followed by Connecticut ($580), California ($540), and Massachusetts ($520). Hawaii and Alaska are expensive largely because they rely on imported fuel for electricity generation, raising costs substantially.

Why is my electric bill high if my rate is low?

Because consumption matters more than rate in many cases. Texas households average 1,096 kWh monthly at 16.44 cents per kWh — roughly $180. California households average 503 kWh at 33.25 cents — roughly $167. Texas pays half the rate and a higher bill, driven by air conditioning load.

What is the biggest utility expense in a home?

Electricity for most households, and within electricity, heating and cooling is the dominant use. This is why thermostat management and air sealing produce more savings than any other single intervention.

Does closing vents in unused rooms save money?

Generally no, and it can cause harm. Central HVAC systems are designed for specific duct pressure and airflow. Closing vents raises static pressure, which can reduce efficiency, strain the blower, and in some cases cause coil freezing. Savings are small and the damage risk is real.

How much can I realistically lower my utility bill?

A household making the high-value changes — thermostat setback, air sealing, water heater temperature, cold-water laundry, and renegotiating internet — can commonly reduce total monthly cost by 10 to 20 percent. On a $470 monthly bill that is $560 to $1,130 annually, most of it from HVAC and the internet renegotiation.

Are water and internet cost figures reliable?

Less so than energy figures. Electricity and natural gas data come from EIA utility-reported sources. Water, sewer, and internet estimates in most published guides are modeled projections scaled to local cost-of-living indices, because no authoritative national dataset exists for residential water or internet pricing. Use them as planning estimates, not verified figures.

Should I ask for utility history before buying a house?

Yes, and it is one of the more valuable and least common pieces of due diligence. Twelve months of actual bills for that specific house accounts for its insulation, HVAC age, window quality, and orientation in a way no regional average can. A buyer moving between climates can see the largest surprise in this category.
