Once a public corp has between $40-50B, cash, it'll pay out around 4B in dividends.
Check the "net profit" graph out for the corp. The big periodic downward spikes are the dividend payouts.
Depending on what you are interested in, you could figure out an average monthly dividend, and multiply by the percentage of shares you hold, and that's the average monthly payout you should get.
say average dividend of $1B/month*10% shares=$100M/month on average.
