I don't think the women's tournament has a payout.
The NCAA doesn't have an individual contract for the women's tournament - they have a contract with ESPN for the women's championship, plus lacrosse, etc., etc. That contract pays out like $15M a year, so the women's tournament gets some fraction of that.
But the NCAA loses a substantial amount just hosting the event in various venues - ticket sales do not pay the expenses.
At the end of it, if the schools participating don't lose money, I think they're happy.
