Why does this differ from my actual utility bill?
Nameplate wattage is often a maximum, not a constant draw. Cycling appliances like fridges and freezers, your exact usage pattern, and your utility's rate structure can all shift the real number.
Where do I find my appliance's actual wattage?
Check the nameplate or label on the unit itself, usually on the back or bottom, or the manufacturer spec sheet.
Should I use a plug-in energy monitor instead of estimating?
If you want an exact figure rather than an estimate, yes — a plug-in monitor measures actual draw over time, which accounts for cycling and real usage patterns an estimate cannot.
Does time-of-use electricity pricing change this?
Yes, if your utility charges different rates by time of day, your actual cost can differ from a flat-rate estimate — check your specific rate plan.
