Economics = (Land x Technology) +/- Unique "trump" cards - Military strength

Plug in the equation with various navies. Let's start with UAC.

UAC has the most territory and is high tech. But, they field huge numbers of ships and put a lot into research.Let's put the scale for everything on a scale of 1-100, 1 being the least, and 100 being the most.

So.

Economics = (100*90) + (EAF trade relations, which is 50) - 200 (since their fleet, weapons, training and SPARTAN program cost a lot.

In the end, the answer is

Economics = 900 + 50 - 200

So, UAC's economy is 750, on a scale of 0-100, 75.
