About Plug & Penny

What your home really costs to run.

Energy bills are made of small numbers that add up: the watts on a label, the hours something runs, the price per kWh on your bill. Plug & Penny turns those into plain answers for households in the United States and the United Kingdom: what an appliance costs to run, which option is cheaper, and where the savings really are.

How we work

• Official data first. Prices come from the U.S. Energy Information Administration and Ofgem; appliance figures from ENERGY STAR and manufacturers' specifications. Every guide lists its sources.
• Show the working. Our calculators show the formula, and you can enter your own price.
• Dated and updated. Prices change, so every guide shows when it was last checked, and we update the figures when new official data comes out.
• No fake testing. We don't claim to have tested products we haven't. Comparisons are based on published specifications and official data, and say so.
