The counter at the top of the screen shows budget. This is derived from the hull table. It decreases as you add components, until it reaches zero, at which point you have no budget left.
The line in the stat block is slightly different:
Cargo Units X (Y available; capacity Z tons)
X is the initial budget
Y is what’s left of the initial budget
Z is Y in tons where 1Y = 50 tons.
So here’s an example from the book:
Gagarin Class VI Research Vessel
Weight 75777 tons; Cargo Units 800 (76 available; capacity 3800 tons)
