How to Calculate
The Electricity Cost Calculator estimates energy usage and costs based on appliance wattage and daily usage.
Formula:
- Daily Usage (kWh) = Watts x Hours per Day / 1000
- Monthly Usage = Daily Usage x 30 days
- Cost = Usage (kWh) x Price per kWh
Average US residential rate: ~$0.16/kWh (varies by state)

FAQ
How do I find my appliance wattage?
Check the label on the back of the appliance or its user manual. The energy guide label also shows estimated power consumption.
Does this account for tiered pricing?
This calculator uses a flat rate. Actual costs may differ if your utility uses tiered or time-of-use pricing.
