Estimate household or small-business electricity use from the equipment you actually operate. Start with an appliance load list, then enter quantity, electrical input watts, daily operating hours and the fraction of those hours drawing the stated power. The Electricity Cost Calculator reports kWh and energy charges for each load using your chosen number of days and tariff. It supports scenario comparisons, input links and a downloadable inventory. Use 100% duty when your watt value is already an average over the entered operating window. For lighting upgrades, compare the existing and proposed input power at the required light output, then include purchase and installation costs when assessing payback. Generator planning is a separate task because starting demand and transient performance matter. Browse the tools below and read each model’s assumptions.
