Calculation method and limits

Watts ÷ 1000 × hours × days gives energy. Multiply per-cycle energy by cycles; annual energy is used directly. Monthly and daily averages divide the annual estimate by 12 and 365. Seasonal bills, changing fixed charges, tiers and time-of-use rates are not predicted. Maximum label watts may differ from average power.
