If you are buying a typical home in Clarksville or Montgomery County, plan on budgeting roughly $300–$400 per month for electricity, water and sewer, natural gas if applicable, trash service, and internet combined. Smaller, newer, or energy-efficient homes may cost less, while larger or older homes can cost considerably more during periods of heavy heating or air-conditioning use.
Your actual utility costs in Clarksville TN will depend on the home’s size, age, insulation, HVAC system, number of occupants, water usage, service providers, and seasonal weather. Use the figures below as a planning range: not a guaranteed bill: and contact each provider for current rates before you close.

What should Clarksville homebuyers budget for utilities?
A practical monthly planning range for a typical owner-occupied home looks like this:
| Utility | General monthly planning range |
|---|---|
| Electricity | Approximately $120–$200 or more |
| Water and sewer | Approximately $60–$110 |
| Natural gas, if used | Approximately $25–$90 depending on season |
| Trash service | Approximately $15–$30 |
| Internet | Approximately $50–$90 |
| Estimated total | Approximately $300–$400 for many households |
These ranges are intentionally broad because utility bills are property-specific. A 1,500-square-foot townhouse with efficient appliances will not use energy the same way as a 2,500-square-foot home with an older HVAC system, several occupants, and extensive lawn watering.
If you are comparing monthly ownership costs, include utilities alongside your mortgage payment, property taxes, insurance, HOA dues, maintenance, and commuting expenses. For additional budgeting guidance, review Haus’s guide to how much house you can afford in Clarksville.
Electricity costs in Clarksville
Electricity is often the largest and most variable utility expense for Clarksville homeowners. Many properties in the Clarksville area receive electric service from CDE Lightband, although the provider can vary by location.
Your electric bill generally includes a customer charge, energy usage, and other applicable charges. CDE Lightband publishes its current residential rates and fees online, so check the official schedule rather than relying on an older estimate.
For planning purposes, many buyers should expect electricity to fall somewhere in the low hundreds of dollars per month, with significant variation throughout the year. A smaller or newer home may stay toward the lower end of the range. A larger home, an older HVAC system, poor insulation, or extensive summer cooling can push the bill much higher.
Why summer electric bills can rise
Clarksville’s warm, humid summers can place substantial demand on an air-conditioning system. Your electric usage may increase when:
- The home has an older heat pump or central air unit
- The HVAC system is oversized, undersized, or poorly maintained
- The attic or ductwork is inadequately insulated
- The thermostat is set significantly lower during the day
- Windows allow substantial heat transfer
- Several people are home throughout the day
- The home has electric water heating or other high-use appliances
Ask the seller or listing agent whether utility history is available. A full year of bills is more useful than a single mild-weather month.
Water and sewer costs
Clarksville Gas & Water generally provides water and sewer service within its service area. The monthly bill may include a base charge plus charges based on consumption.
For many households, a reasonable planning range for water and sewer combined is approximately $60–$110 per month. Lower-use households may spend less, while larger families or properties with significant outdoor watering may spend more.
Water usage can increase because of:
- Lawn and garden irrigation
- Leaking toilets or faucets
- Older plumbing fixtures
- Frequent laundry
- More household occupants
- Filling pools or watering new landscaping
- Guests or short-term increases in occupancy
Before purchasing, ask whether the property has a separate irrigation meter, unusual plumbing features, or a history of elevated water consumption. You can also review the City of Clarksville’s water and sewer rate information and confirm current charges directly with the utility department.
A home with a large yard may have attractive curb appeal but require more water and ongoing landscaping expense than a townhome or smaller-lot property.
Natural gas costs
Some Clarksville homes use natural gas for heating, water heating, fireplaces, dryers, or cooking. Other homes are fully electric. Clarksville Gas & Water provides natural gas service in portions of the area, but availability depends on the property.
If a home uses gas, plan for seasonal variation rather than one consistent monthly amount. Gas costs may be relatively low during warmer months and increase substantially when the furnace operates regularly.
Your gas budget will depend on:
- Whether the home uses gas heat
- Whether the water heater is gas or electric
- The age and efficiency of the furnace
- Thermostat settings
- Home insulation and air sealing
- Winter temperatures
- The size of the home
An all-electric property may have no separate gas bill, but that does not mean the home has lower total energy costs. Electric heating and water heating can shift more of the household’s energy expense onto the electric account.
During your inspection period, ask the inspector to identify the heating and water-heating systems. Knowing the equipment type will help you estimate how the home may perform during both summer and winter.
Trash and solid-waste service
Trash collection is another expense that buyers sometimes overlook. In many Clarksville and Montgomery County neighborhoods, homeowners arrange curbside pickup through a private provider rather than receiving the service as part of a single municipal utility bill.
A general planning range is approximately $15–$30 per month for routine residential pickup, although service levels and provider pricing vary. Additional charges may apply for large-item pickup, extra containers, recycling, or special disposal.
Ask these questions before closing:
- Is trash service already active at the property?
- Which company currently provides pickup?
- How frequently is collection scheduled?
- Are recycling or yard-waste services included?
- Are there separate county or landfill-related fees?
- Does the neighborhood have an HOA-arranged service?
If you are purchasing in a planned community, the HOA may include or coordinate trash service. Confirm whether that expense is included in your monthly dues or billed separately.
Internet costs for Clarksville homes
Internet service is usually separate from traditional utilities, but it belongs in your monthly homeownership budget. Many households should plan for approximately $50–$90 per month, depending on speed, equipment, promotions, and whether internet is bundled with television or phone service.
Your needs may differ based on:
- Remote work or telehealth
- Online gaming
- Streaming across multiple devices
- Home security cameras
- Smart-home equipment
- Number of residents
- School or work requirements
Before making an offer, verify which providers serve the exact address. Availability can differ between nearby streets, especially in developing areas or more rural portions of Montgomery County. Promotional pricing may also expire after the first year, so ask for the regular monthly rate, equipment charges, installation fees, and contract terms.
What factors affect utility costs the most?
The biggest drivers of utility costs in Clarksville are usually the home’s size, construction quality, HVAC system, and occupancy.
Home size and layout
A larger home generally requires more energy to heat and cool. High ceilings, bonus rooms, finished basements, and multiple HVAC zones can also affect consumption.
Age and condition
Newer construction may have more efficient windows, insulation, appliances, and HVAC equipment. Older homes can still be economical, but you should examine insulation, ductwork, air sealing, and equipment age carefully.
Seasonal weather
Expect utility use to fluctuate. Summer cooling can increase electricity consumption, while winter heating can increase either electric or natural-gas usage.
Number of occupants
More residents generally means more showers, laundry, cooking, lighting, electronics, and water consumption.
Maintenance and habits
Replacing HVAC filters, sealing drafts, repairing leaks, using programmable thermostat settings, and maintaining appliances can help control bills over time.
How to verify utility costs before buying
Online averages are useful for an initial budget, but the best information comes from the specific property.
Before you close, ask for:
- At least 12 months of utility bills, if the seller is willing to provide them.
- The current provider for each service.
- The age and type of HVAC and water-heating equipment.
- Information about irrigation systems or unusually high water use.
- Any HOA-provided or separately billed services.
- The regular internet rate after promotional pricing ends.
Remember that a seller’s bills may not match yours. A property may have been vacant, occupied by fewer people, or kept at different thermostat settings. Treat the history as useful evidence: not a promise.
How utilities fit into your homebuying budget
Utilities should be included in your complete monthly housing calculation. If your mortgage, taxes, insurance, HOA dues, and maintenance already stretch your budget, even moderate utility costs can make ownership uncomfortable.
When you compare Clarksville with nearby communities, look beyond the purchase price. Haus’s Oak Grove versus Clarksville cost-of-living guide can help you consider housing, commuting, amenities, and other expenses across the Clarksville and Fort Campbell area.
You may also want to compare ownership costs with rental expenses using Haus’s guide to renting versus buying in Clarksville.
Final answer: What are utility costs in Clarksville TN?
For many Clarksville homebuyers, $300–$400 per month is a reasonable starting budget for electricity, water and sewer, gas if applicable, trash, and internet. Smaller, newer, or highly efficient homes may cost less. Larger homes, older systems, heavy HVAC use, and high occupancy can push monthly expenses higher.
Before you finalize your purchase, verify current provider rates and request the property’s utility history. A Haus professional can help you evaluate the home’s full monthly cost: not just the list price or estimated mortgage payment.
