Calculate water bill metrics, household utility expenses, and home appliance parameters with ease.

💡

Home & Utility Inputs

Enter wattage rating, hours of operation, or utility rate.

Power Rating (Watts) / Room Area (sq ft)

Daily Usage (Hours) / Electric Rate ($/kWh)

$28.80 / Month 180 kWh Monthly Consumption

💡

Replacing incandescent bulbs with ENERGY STAR LEDs reduces lighting power consumption by 75-80%.

📐

Cost ($) = (Watts × Hours / 1000) × 30 Days × Electric Tariff ($/kWh)

Applies US Department of Energy (DOE) appliance testing standards and ASHRAE building load principles.

📢

Electric bills include fixed customer charges and variable tier rates not reflected in simple kWh multiplication.

Follow these simple steps for utility budgeting:

Find the rated power (Watts or kW) on the back UL label of your device.

Enter average hours used per day and your electric utility tariff rate ($/kWh).

Instantly view calculated monthly electricity expense in dollars and annual kWh consumption.

Understanding appliance power draw enables smart home energy management and reduces monthly electric bills.

Input

Appliance wattage consumption rating and daily runtime.

Output

Total kilowatt-hours used and dollar bill amount.

How many BTUs of AC cooling are needed per square foot?

As a general rule, an air conditioner needs 20 BTU per square foot of living space (12,000 BTU = 1 Ton of cooling).

What is insulation R-value?

R-value measures building insulation thermal resistance. The higher the R-value, the greater the insulating effectiveness.
