3 ways to estimate utility costs
If you’re looking to get a general idea of how much you’ll spend per month on utilities in your new home, there are three main ways to obtain this information:
1. Ask your real estate agent
Real estate agents can help estimate utility costs by reviewing historical data from the seller’s agent or annual utility costs of comparables. If you’re looking to estimate utility costs for a rental home or apartment, you can ask a landlord or apartment manager instead.
2. Ask the current resident
If possible, ask the current homeowner what they typically pay each month. You don’t need exact bills – even a ballpark range can be helpful. “The most reliable way to estimate monthly utility expenses before purchasing a home is to request a 12-month usage history from the current owner.” says Kelly Bedrich, the cofounder of ElectricityPlans.com, a comparison site for electricity in states where energy choice is deregulated. “While this will not account for differences like thermostat settings or number of occupants, it’s the best way to approximate your usage. “
3. Ask utility providers
You can reach out to local utility providers and ask for an estimate for the place you’re moving into. Most companies can give you an average monthly cost for your specific address based on the past year’s usage.

Factors that influence utility costs
Utility costs vary greatly by home, state, size, etc. so it’s important to look at the variables that can affect these costs when estimating.
- Location: Utility costs vary greatly by state due to differences in energy sources, pricing regulations, and infrastructure.
- Climate: Climate plays a big role in specifically heating and cooling costs. For example, homeowners in colder climates may spend more on heat while those in hotter regions may have higher electricity bills from air conditioning usage.
- Number of occupants: Larger households can see higher electricity, water, sewer, and sometimes internet bills due to increased usage. Households with young children or retirees can also see higher bills due to the increased time spent at home.
- Usage habits: Frequency and efficiency heavily influence utility costs, specifically the energy, water, gas, and sewer bills.
- Home size: The larger the home, typically the higher the utility bills. More square footage means more energy to heat, cool, and power.
- Home age: Older homes have the potential for outdated infrastructure like less efficient insulation or aging HVAC systems that will require more energy to operate. Some newer homes have updated systems and modern technology like double-pane windows or solar panels that can help reduce utility expenses.
- Inflation: Inflation affects every aspect of the economy, including rates charged by utility providers so you can expect costs to change as the economy does.
According to Kelly Bedrich, heating and cooling your home “accounts for around 50% of your electricity usage. You can keep your electricity bill low by using recommended thermostat settings and by running a DIY energy audit on your home shortly after you move in. That helps identify where air and energy are escaping from your home and driving up your utility bills.”

What are energy efficiency ratings?
