He split the $3 million deal with Jesse -- $1.5 million each. The deal was changed in "Kafkaesque" to $15 million for the year, open-ended, and that was was also split with Jesse -- $7.5 million each, minus expenses. Walt brings in $274,000 every two weeks (Walt tells Skyler this in "Problem Dog").

Walt only worked for Gus in the superlab for about two months, I think, or maybe two months and one week or two weeks. I'm working with this timeline, plus Jesse's "A couple of weeks back, I killed a dog" statement in "Problem Dog," and I'm only guessing how much time passed between "Problem Dog" and "Crawl Space," so someone correct me if they have a better estimate. BB's timeline can be hard to keep straight. Let's say he completed at least eight or ten weeks of work. That works out to $1.096 million or $1.37 million. Add that to the approximately $500,000 Walt still had from the initial thirty-eight pound/$1.2 million deal with Gus (he had to give Saul a cut, and he split the money with Jesse -- Jane tried to blackmail Walt, Walt delivered Jesse's half of the money, Jane died, Saul held the money for Jesse while he was in rehab, and when Jesse left rehab he used $400,000 to buy his aunt's renovated house from under his parents), and you have about $1.596 million or $1.87 million.

Let's suppose that he made at least $2 million. The $800,000 car wash ate up a good chunk of that. Ted's $617,000 ate up quite a bit too. Together that's $1.417 million. Then we have Jr.'s Challenger, paying for the destruction of the Challenger, Walt's condo, the .38 snub with the serial numbers filed off, Jr.'s PT Cruiser, Walt's medical bills, Hank's rehab bills, paying Saul to perform various jobs, etc.
