Terms of use

PowerCost Lab provides planning estimates and educational information—not billing guarantees, engineering advice, or a substitute for professional assessment.

Estimates, not guarantees

Results depend on user inputs and simplifying assumptions. Actual consumption and cost can differ because of appliance condition, voltage, weather, occupancy, tariffs, taxes, fixed charges, losses, and measurement error.

Safe use

Do not open electrical panels, modify wiring, or connect unsuitable meters based on this website. Use equipment rated for the appliance and jurisdiction, and consult a qualified professional where appropriate.

Contributed data

Only contribute data you are permitted to share and that does not contain personal information. You grant PowerCost Lab permission to aggregate and use submitted measurements to improve its models, research, and products.
