Lighting Operating Cost Calculator
What does the Operating Cost Calculator do?
It estimates annual electricity cost for any lighting system using wattage, hours, and your rate.
Do I need utility bills?
Not required, but your cost per kWh makes results more accurate.
Can I use it for just one fixture?
Yes, it works for single fixtures or whole buildings.
Does it include demand charges?
No, it calculates energy cost only. Add demand separately if your bill includes it.
Can I test different schedules?
Yes, adjust the hours to see how usage affects annual cost.
Can it compare two systems?
Yes, run the calculator twice (legacy vs LED) to see the difference in cost.
Does it show monthly cost?
Yes, results show both monthly and annual operating costs.
What rate should I use?
Enter your blended $/kWh. For TOU or ULO overnight, estimate a weighted average.
Does it include maintenance?
No, this tool focuses only on energy cost.
Does it save my data?
No, save or print your results before closing.
Can I use it for non-lighting loads?
Yes, it works for any electrical load if you know wattage and hours.
Who should use this tool?
Facility managers, small business owners, or anyone budgeting energy costs.
