Use the kWh figure from the label or spec sheet, then multiply by your electricity unit rate.

Use the kWh figure from the label or spec sheet, then multiply by your electricity unit rate.

If it’s listed as kWh per 24 hours (kWh/24h):

Annual kWh = (kWh/24h) × 365

Annual cost = Annual kWh × your € per kWh

If it’s listed as kWh per year (kWh/annum):

Annual cost = (kWh/year) × your € per kWh

If you only have a power figure in kW:

Annual kWh ≈ kW × average hours running per day × 365

(Commercial freezers don’t run 24/7 at full load, so this is only a rough estimate unless you measure it.)

For a quick “owner quick checks card” beside the unit, write your current rate and a one-line formula staff can use: € per year = (kWh/24h × 365) × € per kWh.
