Utilities in Apartment: Average Monthly Costs Explained

Rent is only part of what an apartment costs. Utilities are billed on top in most leases, and the bill depends on which services the landlord includes. A building might cover water, sewer and trash in the rent and leave you to pay electricity, gas and internet. Another might split everything by unit, meter by meter, or charge a flat fee. Reading the lease for what is included is the first step toward a realistic budget.

The figures here come from a rental-advice guide, a crowd-sourced cost-of-living database, an electricity-rate estimate and a local example for Houston. They define "utilities" differently, so read each description before comparing them.

Utilities usually cover six services:

• Electricity for lights, appliances and cooling
• Natural gas for heating, hot water or cooking, in buildings that use it
• Water and sewer
• Trash and recycling
• Internet
• Sometimes cable or streaming, though that is closer to a discretionary expense

Some tenants also pay a pest-control or common-area fee, which usually shows up in the lease as a flat charge. Internet is not a utility in the strict sense, but most budgeting guides include it because a household needs it.

The two sources below take different approaches. Trulia, a rental marketplace, gives a range for a typical apartment that covers electricity, gas, water, sewer, trash and internet. Numbeo draws on user submissions and reports basic utilities for a mid-sized apartment. Its figures cover electricity, heating, cooling, water and garbage, and the crowd-sourced data has a wide spread.

Because Numbeo is built from user reports, treat its numbers as a rough reference. The page says it was updated in October 2026. Its average sits inside the Trulia range, though its low and high values are much more spread out.

Electricity is often the biggest utility bill for apartment renters. One estimate that applies a national electricity rate to a typical one-bedroom puts the bill at $90 – $134/mo. That estimate is a calculation based on the federal Energy Information Administration's average rate for August 2026, so a building in a high-rate state or a hot climate could be above it, and a mild climate with efficient appliances could be below it.

Heating and cooling account for much of the variation. A unit with electric heat and no insulation can cost far more in winter than one with gas heat. Window position, the age of the building and the floor you live on also affect how hard the system works.

A national average hides regional differences. A SmartAsset cost-of-living guide for Houston puts a basic utility package for an apartment there at $211.55/mo. That figure applies to one city with a hot climate and heavy air-conditioning use. A renter in a cold northern city would face a different mix of costs, so use your local utilities to check any national figure.

Several factors matter more than the listed averages:

• Climate: both extreme heat and cold raise energy use
• Apartment size: larger units take more energy to heat and cool
• Number of residents: water, trash and electricity rise with occupancy
• Heating fuel: gas, electric and shared building systems price differently
• Local rates: electricity, water and sewer rates vary widely across cities and utilities
• Habits: thermostat settings, laundry and long showers

Whether the building bills by meter or splits shared costs by a formula changes things too.

Ask the landlord or property manager what the previous tenant paid. Some local utilities will share a unit's usage history if you ask, and some publish typical bills. Check whether the apartment uses gas or electric heat. Read the lease for which utilities are included, and look for flat fees for trash or pest control.

Also compare internet options in the building. Some properties have exclusive providers, which limits your choices. If the landlord bundles internet with rent, compare the total with what you would pay on your own.

Small changes add up over a year. Set the thermostat a few degrees closer to the outdoor temperature, seal gaps around doors and windows, and run full loads in the dishwasher and washer. Switch to LED bulbs if the landlord has not. Close blinds in summer to block sun and open them in winter. Ask your utility about budget billing, which spreads costs evenly through the year, and about low-income or senior assistance programs.
