Resting energy at that weight is about 1446 kcal per day. The Merck neutered-adult factor of 1.6 puts maintenance near 2314 kcal before activity is added. The dog food calculator on this page uses that same resting-energy formula, then applies the activity and size adjustments from the main dog food calculator.
