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 Estimate Monthly Total What It Includes $470/month $5,640/year Electricity, gas, water, internet (~$65), trash (~$30) $610/month $7,320/year Broader 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 Category Typical Monthly Range Notes Electricity $120–$180 Largest single utility for most households; EIA national average ~$144 (2024) Natural gas $60–$130 Highly seasonal; near zero in summer in many climates Water and sewer $36–$60 Sewer often costs more than the water itself Internet $65–$100 Rarely varies with usage; a fixed monthly commitment Trash and recycling $25–$40 Sometimes 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: State Electricity Rate Monthly Consumption Est. Electric Est. Total Utilities Texas 16.44¢/kWh 1,096 kWh $180 $405 Pennsylvania 21.55¢/kWh 817 kWh $176 $360 New Jersey 23.27¢/kWh 662 kWh $154 — New York 29.93¢/kWh 571 kWh $171 — California 33.25¢/kWh 503 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 Type Typical Monthly Utilities Primary Driver Studio / 1-bedroom apartment $150–$250 Small conditioned volume; shared building systems 2-bedroom apartment $200–$320 Moderate load; often no separate water bill 1,200–1,500 sq ft house $320–$450 Full responsibility for all utilities 1,800–2,200 sq ft house $400–$550 Standard benchmark used in most estimates 2,500–3,500 sq ft house $500–$750 HVAC 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.
