Tips for a fair comparison

Compare at the same output. A 1,500 W space heater on high and an oil-filled radiator on high deliver the same heat, but the radiator cycles less once the room is warm. Set the "Runs % of the time" field to reflect that.
Use real hours. Running costs scale directly with hours. Use Duplicate to compare the same device at two schedules.
Check the EnergyGuide label. For fridges, freezers, washers, water heaters and TVs, the label's kWh/year is the most accurate number. Pick "kWh per year" and enter it, or look up the model.
Add the purchase price. Divide the price difference by the yearly saving to get the payback in years.
