Seriously -
Each academy determines the "cost" in different ways - some take the actual academy budget and divide by the number of cadets/mids (taking into account building/grounds maintenance, snow removal, etc) while others include (or exclude) the ~$11k pay of each. Some include the cost of summer training & transportation, some do not.
The USCGA values the "scholarship" (whatever that entails) at $290,000.
I have no information as to what this amount includes or excludes.
