# The relationship between basal metabolic rate, calories, and activity level

I have a base BMR of about 2200 calories without the activity multiplier using this formula:

66 + (6.23*240) + (12.7 * 70) - (6.88*31)

I supervise an automotive shop and generally consider walking, sitting, and standing as my daily activities (about 1500 calories burned using weight times METS). In the context of weight loss and calorie intake and calories burned, would my said daily activities be the multiplier (1.2) or is that multiplier added in regardless of what daily activity is?

I ask because 2200 x 1.2 would be 2640 calories burned + work = 4140 which seems high. Without the multiplier 2200 + 1500 = 3700 still seems high. If I'm deducting 500 per day, 3200 calories seems really high. I'm 240lbs with a 5'10" frame and this doesn't really make sense to me. Am I missing something? Is my estimation on calories burned for my daily activities way off? I consume anywhere from 2000 to 3000 calories per day on average.
