Most homes spend the bulk of their energy budget on heating, cooling and water heating. Electricity usually dominates the bill, with natural gas covering heat and hot water in much of the country. Knowing your annual total is the first step to finding savings.
How it’s calculated & sources
Annual cost = (monthly kWh × rate × 12) + (monthly gas bill × 12). Compare the total to typical national spending to gauge whether you’re high or low.
Benchmark: the average U.S. household spends roughly $2,000/year on home energy — about $1,800 on electricity plus gas (EIA).
