Measured, not marketed.
Official registry data, priced with your utility's actual tariff.
The label on an appliance estimates a year's cost on a national average price. This site takes the same filed test figures and prices them on the tariff your own utility charges, with the source and pull date on every number. Water heaters and clothes washers in the United States are open.

About this site
What it does, what it refuses to do and who to write to when a number looks wrong.
Why this number differs from the label
The yellow label's yearly cost is built on a national average energy price, and it stops at one year — not the ten or fifteen you will own the heater. The figure you actually want is derivable from the same published test data, priced on your own rate. Nobody derives it for you; this site does, and shows the source and the pull date next to the result.
How every figure is calculated, and where published costs disagree with each other.
