Hi, I have set up a new SMSF this FY through an accountant. There are four members. One member adds his super every three months. Another member adds his super fortnightly. The other two members only add lump sums at the moment. I trade shares for the fund. Is there a formula for calculating the percentage each member gets of the profits on a fortnightly or weekly or daily basis so that each member has the correct percentage of the profits? I do not want to use proprietary super software as I want to keep costs to a minimum. I have set up my own excel spreadsheets to give a view of each member's inputs and for the overall fund. Thank you.
