How do I measure the annual running cost of a 18 W LED ceiling lighting fixture compared to 40W fluorescent lamp?

The running costs can be determined by the following.
Annual running cost $ = Wattage /1000 KWH x Hours (Number of hours use per day) x cents per KWH (Cost of electricity)
Example: What is the annual savings when I compare a Dailux energy saving 18 W LED ceiling lighting fixture used for 10 hours per day, 7 days per week, 52 weeks per year, with the cost of electricity at 21 cents per KW Hour ?
Annual Cost for 18 W LED ceiling lighting fixture = 18/1000 x (10 x 7 x 52) x $0.21 = $13.759
Annual Cost for 40W fluorescent lamp = 40/1000 x (10 x 7 x 52) x $0.21 = $30.576
Based on the medium size parking garages with an average of 30x 40W fluorescent lamp and a cost of electricity at 21 cents per Kilowatt hour, the annual savings would be more than $500 per year.
