Electricity Cost Per Day Calculator
U.S. residential EIA benchmark: 18.34¢/kWh ($0.1834) — June 2026 (Table 5.6.A)
The Electricity Cost Per Day Calculator determines daily electricity expenses from measured daily kilowatt-hours or device runtime. It projects weekly, monthly, and annual expenses to help manage daily household energy budgets.
U.S. residential EIA benchmark: 18.34¢/kWh — June 2026
This is a state/national macroeconomic benchmark from EIA Table 5.6.A, not a guaranteed residential tariff. Your actual electric bill can vary by utility, electricity plan, usage band, fixed customer charges, fees, taxes, riders, and other applicable charges.
Electricity Cost Per Day Calculator
Calculate daily electric power costs from metered daily kWh or appliance runtime and project weekly and monthly totals.
Editable. Enter your volumetric supply + delivery rate per kWh from your electric bill.
Defaults to $0 for pure volumetric electricity cost. Enter your utility's monthly/annual account fee if estimating a full bill.
Defaults to $0. Enter any specific municipal utility taxes or regulatory rider amounts from your bill.
Assumes electricity usage, rate, and fixed charges remain unchanged.

Daily Electricity Cost Formula
Multiply total daily kilowatt-hour consumption by your volumetric electricity rate per kWh.
- Daily Energy (kWh/day): Total kilowatt-hours consumed over a 24-hour day.
- Electricity Rate ($/kWh): Volumetric utility rate per kWh ($0.1834/kWh EIA benchmark — June 2026).
- Weekly Cost ($): Projected 7-day electrical energy expense.
Worked Example: Typical US Home Consuming 30 kWh per Day
Calculating daily, weekly, and monthly costs for a home consuming 30 kWh per day at the national benchmark average rate ($0.1834/kWh — June 2026):
Calculation Assumptions & Cost-Saving Strategies
- Calculations reflect volumetric energy consumption without fixed monthly meter fees.
- Daily usage can be checked via utility smart meter dashboards (Green Button data).
Target 5 kWh Daily Reduction
Turning off unused appliances, adjusting thermostat 2 degrees, and washing clothes in cold water saves ~5 kWh daily.
Air Dry Laundry on Sunny Days
Electric clothes dryers draw 3–4 kWh per cycle ($0.55–$0.75 per load). Air drying saves $15–$25 monthly.

Frequently Asked Questions: Electricity Cost Per Day Calculator
How many kWh per day is normal for a house in the US? +
The average US household uses about 29.5 to 30 kWh per day (899 kWh per month). Small apartments use 10–15 kWh/day, while large all-electric homes with EV charging can exceed 50 kWh/day.
How do I calculate my daily electricity cost from my monthly bill? +
Divide your total monthly bill by 30 days. For instance, a $165 monthly electric bill averages $5.50 per day.
