WattNoteRefrigerator replacement: compare annual energy
Your appliance’s estimated energy cost
What this estimate uses
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.

A refrigerator can stay plugged in all day without its compressor drawing the same power continuously. Do not treat instantaneous power multiplied by 24 hours as measured annual consumption. Prefer annual kWh or measurements over a suitable period.
Annual and monthly kWh differ. In the buying calculator, divide an annual value by 12 for monthly energy and enter 12 months. The keep/repair/replace tool accepts annual energy directly.
Fictional example: 480 versus 320 kWh per year differs by 160 kWh. At 0.2 currency units/kWh, that is 32 per year and 160 over five years. If the extra purchase cost exceeds this, energy savings alone do not recover it within that period.
Do not rank refrigerators with different capacities or purposes on cost alone. Include continued use only if the current unit is functional and safe. This tool cannot assess cooling faults or food-storage safety.
Distinguish confirmed repair quotes from guesses. Do not add the original purchase price again when comparing future repair and replacement choices. Historical passport records and future cost comparisons serve different purposes.
