What this calculator does not tell you

It counts electricity only. Purchase price, repair costs, delivery, and whether your current monitor still works well are separate parts of the decision.
The ENERGY STAR figure for a new model is a standardized value. Your own use will differ with how the appliance is used and where it stands.
Your old figure may be a guess. If you can, measure it.

Typical numbers for each type and state are on the cost to run a monitor by state page. Browse all computer monitors.
