Resting energy at that weight is about 860 kcal per day. The Merck neutered-adult factor of 1.6 puts maintenance near 1376 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.

Reading the portions

Compared with other single-size large breeds, that neutered-adult portion is 54 kcal higher than the 1322 kcal for an average large breed at 59.2 lb.

Portions are a starting estimate. Boxer individuals can vary by body condition, neuter status, and how much they work. Adjust the bowl from what you see on the ribs, not from the table alone.
