Is that graphic from the Navy website? I haven't seen it before, looks cool.
I think there's some caveat to the education, and I generally don't count medical stuff as compensation because it's not cash in my bank account so I conceptualize it differently. Otherwise, that feels pretty accurate, depending on where you're pulling in BAH from. I'm a collegiate right now making E-4 and these calculators are accurate to what I'm making, so I trust that the jump to O-1 will be accurate as well.
