After Asiatrip ended, we got back to MIT and immediately got hosed beyond belief. As such, we only just finally figured out our finances. I did a bit more number crunching, because I wanted to figure out my total spending and where all the money went. This is a rough per-person cost breakdown of our trip, which may be valuable to people planning similar trips. Among the four of us, costs vary basically based on how much each of us bought in electronics and souveniors, whether we went to Japan, visa processing time, and things like that. All costs have been converted into USD.

$280 — preparation (costs before the  trip, like travel items, drugs, gifts)
$1130 — flights (3x)
$140 — trains (4x)
$110 — misc transportation (taxis, buses, subway)
$150 — housing
$90 — food
$100 — discretionary (souveniors, electronics, tourism)

Transportation subtotal: $1380
Total: $2000

Our original estimate was $1.8K, and I was hoping the trip would be under $2K, so this is perfect. 😀
