http://www.mogs.com/eve-isk/Tranquility (just the first google result i found that would quote me a price) sells 40000 Million Isk for $2,098 USD, so that puts the bank in the hole something on the order of $62,500 in actual dollar terms, assuming that I did the math right, and with that exchange rate/liquidity/market.
Not too shabby for an in-game private venture!
