Home Utility Cost Estimator
Estimate your monthly home utility bills — electricity, gas, water, internet, and trash — by home size and region. Use these benchmarks when budgeting for a new home or comparing total cost of ownership.
Monthly Utility Costs by Home Size
Small = under 1,500 sq ft | Medium = 1,500–2,500 sq ft | Large = 2,500+ sq ft
| Utility | Small Home | Medium Home | Large Home | Varies With |
|---|---|---|---|---|
| Electricity | $80–$120 | $120–$180 | $180–$280 | Climate, AC usage, EV charging |
| Natural Gas | $40–$70 | $70–$120 | $120–$200 | Heating climate, gas stove/dryer |
| Water & Sewer | $30–$50 | $50–$80 | $80–$130 | Lawn irrigation, family size |
| Trash & Recycling | $20–$35 | $25–$40 | $30–$50 | Municipality, frequency |
| Internet | $40–$80 | $50–$90 | $60–$100 | Provider, speed tier |

Frequently asked questions
What is the average monthly utility bill for a house?
Average monthly home utility costs: Electricity: $100–$200 (US average: $137). Natural gas: $50–$150 (higher in cold climates). Water & sewer: $40–$100. Trash & recycling: $25–$40. Internet: $50–$80. Total average: $265–$570/month depending on home size, climate, and region. Larger homes and extreme climates (hot South, cold Northeast) push costs higher. Energy-efficient homes with solar can reduce electricity to near zero.
How can I reduce my home utility bills?
Top ways to lower utility bills: Upgrade attic insulation to R-49+ (saves 15–25% on heating/cooling). Install a programmable or smart thermostat (saves 10–12% on HVAC). Seal air leaks around windows, doors, and attic penetrations. Replace windows older than 20 years with double-pane low-E glass. Upgrade to a high-efficiency HVAC (20+ SEER AC, 96%+ AFUE furnace). Switch to LED lighting throughout. Install a tankless or heat pump water heater. Fix dripping faucets and running toilets.
Which states have the highest home utility costs?
States with highest total utility costs: Hawaii (highest electricity rates, $0.35+/kWh), Connecticut and Massachusetts (high electric rates + cold winters), Alaska (extreme heating costs), New York and New Jersey (high rates across all utilities). Lowest utility costs are typically in the Mountain West (Utah, Idaho) and parts of the Southeast with mild climates. Texas has moderate rates but high summer AC bills due to heat.
How much are utilities for a 2,000 square foot house?
For a 2,000 sq ft house, expect: Electricity: $120–$180/month. Natural gas: $70–$130/month in cold climates, $30–$60 in warm. Water & sewer: $50–$90/month. Internet: $50–$80/month. Trash: $25–$40/month. Total: $315–$520/month. Climate zone has the biggest impact — a 2,000 sq ft home in Phoenix pays much more for AC than the same home in Seattle, while a Minneapolis home pays far more for heating.
