Standby consumption

Enter one device per line: name followed by its measured average standby power in watts. Spaces or tabs separate the last number from the name; decimal point or comma is accepted, and a separated W may follow the number. Example values are fictional, not typical product specifications. Use actual standby consumption, not rated operating power. For fluctuating loads, average measured energy over time. Invalid line numbers are reported and excluded; correct them for a complete total. Names up to 120 characters, maximum 1000 lines and 100000 characters.

Standby time is the daily duration in that mode; it need not be 24 hours. Disconnection is part of that time and cannot exceed it. All listed devices share these durations. Energy = total watts / 1000 × daily standby hours × 365. After disconnection, subtract the disconnected hours. The comparison shows the original annual amount, remaining amount and amount saved.

Cost = energy × your price per kWh. Enter your own price and choose currency; no exchange conversion. Assumes a constant tariff, 365 identical days and truly zero consumption while disconnected. No subscription charge, variable prices, timer consumption, switching costs or payback.

Only disconnect devices when suitable for their purpose. This calculation does not determine whether a router, alarm, recorder or other device can safely be switched off. Different daily durations should be calculated as separate groups. Active-mode energy is excluded.
