Colorado Utility Cost Calculator
Calculate utility costs in Colorado using real EIA electricity (16.16¢/kWh) and natural gas rates. Estimated electric ~$109/mo, gas ~$49/mo, water ~$42/mo for a typical home.
Estimate only — these are not official figures
EIA supplies Colorado's 2024 residential electricity-consumption anchor, May 2026 electricity price, and May 2026 natural-gas price. Every displayed result is still an estimate: electricity scales the EIA account average by entered home size and occupants; gas consumption, water use/rate, internet price, and cost-of-living scaling are modeled; aggregate outputs inherit those assumptions. The stored Census income and cost-of-living index do not record a source vintage.
Do not rely on these amounts for budgeting or payment. For exact amounts, check the EIA-861 Table 5.A: https://www.eia.gov/electricity/sales_revenue_price/xls/table_5A.xlsx; Electric Power Monthly Table 5.6.A: https://www.eia.gov/electricity/monthly/xls/table_5_06_a.xlsx; Natural Gas Monthly residential prices: https://www.eia.gov/dnav/ng/ng_pri_sum_a_EPG0_PRS_DMcf_m.htm.

How This Calculator Works
Calculation methodology and assumptions
Utility cost estimation for Colorado. Electricity consumption starts from EIA's published 2024 average monthly consumption per residential customer in Colorado (674 kWh, Form EIA-861 Table 5.A). This is utility-reported grid consumption; electricity produced and consumed behind the meter, such as customer-sited solar, is not a utility sale and is not included. Home-size and occupant scaling remain modeled assumptions, not EIA figures. The electricity price is 16.16¢/kWh (EIA Electric Power Monthly, Table 5.6.A, May 2026), so the estimate intentionally combines the latest annual state consumption anchor (2024) with the latest monthly price available when compiled (May 2026); recheck after EIA's next annual release by 2026-11-15. Colorado's residential natural gas price is $11.92/Mcf (May 2026), from EIA Natural Gas Monthly and converted to $1.1495/therm using EIA's published heat-content factor (1,037 Btu/cubic foot; divide $/Mcf by 10.37). Natural gas consumption (50-80 therms/month depending on climate) and water usage (80-100 gallons per person per day) are modeled planning estimates only; no safely parseable EIA/BLS/Census state-level anchor exists for either. Water and internet/cable rates are likewise modeled estimates scaled to Colorado's cost of living index (105.1, where 100 = national average) -- there is no authoritative statewide government source for either, so these should not be read as verified figures the way the electricity consumption and energy rates are. Percent of income uses Colorado's $82,254 median household income. Colorado's modeled water/internet estimates are near the national average.
Key State Information
Colorado utility context: Electricity consumption 674 kWh/month per residential customer (EIA-861, 2024) | Electricity price 16.16¢/kWh (EIA, May 2026) | Natural gas $11.92/Mcf (EIA, May 2026) | Cost of living index 105.1 | Median household income $82,254 | Estimated monthly electric ~$109 | Estimated monthly gas ~$49 | Estimated monthly water ~$42 (modeled estimate) | Median rent (2BR) $1895/mo.
How to Use This Utility Costs Calculator
- 1
Enter your home details
Enter home size and occupants. Colorado's EIA electricity consumption and energy-rate anchors are pre-filled; home-size and occupant adjustments are modeled.
- 2
Check the energy rates
Review the editable electricity and natural-gas rates against your latest bill. The Colorado defaults come from EIA, but an individual utility plan can differ.
- 3
Adjust the modeled water rate
Replace the water/sewer starting estimate with your local utility rate when available. Water and internet have no authoritative statewide price source and remain planning estimates.
- 4
Review monthly estimates
Compare electricity, natural gas, water/sewer, and modeled internet costs. The result separates source-backed state inputs from modeled usage and scaling assumptions.
Example Calculation
Let's estimate monthly utility costs for the calculator's default 1,800 sq ft, 3-occupant home in Colorado.
The electricity estimate starts from 674 kWh/month, EIA's 2024 average per residential customer in Colorado, at 16.16¢/kWh. Natural-gas usage, water, internet, and the home-size/occupant adjustments remain modeled assumptions.
Result: Estimated monthly utilities: $274 ($3,288/year) — electricity $109, natural gas $49, water/sewer $42, and internet $74. Replace the editable rates with your provider's figures for a household-specific estimate.
What Affects Your Results
Climate
Colorado's climate drives 40-50% of utility costs. Extreme heat or cold increases HVAC usage dramatically. Moderate climates (Pacific Northwest, parts of California) have the lowest energy costs.
Home Size and Age
Larger homes cost more to heat, cool, and illuminate. Older homes (pre-1980) often lack insulation and have single-pane windows — costing 30-50% more than modern efficient construction.
Energy Source
Natural gas heating costs roughly half as much as electric heating in most markets. Solar panels can eliminate electricity bills entirely. Your energy mix drives costs significantly.
Local Utility Rates
Electricity rates range from $0.08/kWh (Louisiana) to $0.45/kWh (Hawaii). Colorado's rate structure (flat, tiered, time-of-use) affects how usage translates to cost.
Tips for Colorado Residents
- Check if Colorado utility company offers time-of-use rates. Running dishwashers, laundry, and EV charging during off-peak hours (typically 9 PM - 7 AM) can cut electricity costs 20-30%.
- A programmable or smart thermostat saves $10-20/month by automatically adjusting temperatures when you're away or sleeping. The $50-$250 device pays for itself in 3-12 months.
- LED lighting uses 75% less energy than incandescent. Replacing 20 bulbs saves approximately $120/year. Many utilities offer free or subsidized LED bulbs through energy efficiency programs.
- Audit your internet bill annually. Call your provider and mention competitor rates — retention departments routinely offer $10-$30/month discounts to prevent cancellations.
- Water heater: lower the thermostat to 120 degrees F (from the typical 140 degree F default) to save $40-$60/year. Add an insulation blanket ($20-$30) for another $20-$40 in annual savings.

Our editorial standardsFrequently Asked Questions
How much are utilities in Colorado?
At the calculator's default home-size and occupant scaling, monthly utilities in Colorado are approximately $274, including electricity (~$109, combining EIA's 2024 state consumption average with its May 2026 price), natural gas (~$49, using Colorado's EIA-verified rate with modeled usage), water/sewer (~$42, modeled), and internet (~$74, modeled). Home-size and occupant adjustments, gas consumption, water, and internet remain planning assumptions you can edit.
What is the average electric bill in Colorado?
Using EIA's 2024 average of 674 kWh/month per residential customer in Colorado with its May 2026 residential price of 16.16¢/kWh gives approximately $109/month. This mixes the latest annual consumption anchor with a newer monthly price, so it is a current-price estimate rather than EIA's published 2024 bill. The EIA figure is utility-reported grid consumption and excludes electricity produced and consumed behind the meter, such as customer-sited solar. Home-size and occupant scaling are modeled assumptions, not EIA household figures.
What is the average natural gas price in Colorado?
Colorado's average residential natural gas price was $11.92/Mcf in May 2026, per the U.S. Energy Information Administration's Natural Gas Monthly report. That converts to about $1.1495/therm using EIA's published heat-content factor of 1,037 Btu/cubic foot.
