Four details that change the number
Scope
What work or usage does the estimate actually cover?
Units
Check whether the price is per project, hour, square foot, or kWh.
Location
Rates and local conditions can change the total.
Timing
Confirm when a price or rate was checked and when it applies.
Electricity prices depend on where you live.
The U.S. Energy Information Administration reports a preliminary 2025 residential average of 17.30¢ per kWh. That historical national average is context, not a quote for your current bill.
For your own estimate, use the rate and charges that apply to your utility plan. See the EIA data and its explanation.
A starting point for a better estimate.
Every project and household is different. Check the assumptions, compare like-for-like quotes, and confirm current prices with the provider before committing.
