How it works

For each appliance: kWh_month = watts x hours_per_day x quantity x days / 1000. cost = kWh_month x tariff. total_kwh = sum of kWh_month; total_cost = total_kwh x tariff. The three largest users are listed. Fixed monthly charges and stepped (block) tariffs are not modelled, so the real bill can differ.
