Catering portion guide
Plan on about 3 oz of cooked taco meat per person, which fills 2 to 3 tacos. Ground beef loses about 25 percent in the pan, so buy roughly 4 oz raw per person: 50 guests needs about 9.5 lb cooked from about 12.5 lb raw.
Ground beef loses roughly a quarter of its weight to rendered fat and moisture. Leaner blends lose less.
Planning factor: 1.33x. For every 1 lb you want to serve, order about 1.33 lb of raw ground beef.
Order is what to buy as raw ground beef. Serves is what reaches the plate after trim and cooking.

These are standard food-service planning figures, not fixed constants. Real yield moves with cut, trim level, cooking method, and how long the food is held. Weigh your own results once and adjust the factor to your kitchen.
