Operating Cost Calculator
This calculation assumes a continuous load based upon the total watts losses of the transformer.

Definitions
The power from your utility is measured in kilowatts (kW). One kW equals 1000 Watts. The cost per kilowatt-hour (cost/kWh) is the cost of the power from your utility. Call your local utility provider for this information.
No-load losses (in Watts) are energy losses a transformer experiences while not under load. The current necessary to energize the core results in some losses at all times. No-load loss values are available from the transformer’s manufacturer.
100% load losses (in Watts) are energy losses a transformer experiences while under full load. 100% load loss values are available from the transformer’s manufacturer.
A transformer is an electrical device that takes a given input voltage and changes it to a different output voltage. This change can either be an increase or a decrease in voltage. Learn What Transformers Are, and How They Work
