Sanlaam has a crazy rate of a deal there is for both short term and longterm. With the percentage calculated the returns in the 1st withdrawal for unit trusts is 11.0640(no of days) / 100= 4.24 this gives you an exact yield expected then multiply by the cash you have i.e the minimum 2500 4.424= 11060ksh, so by a period of a month and 10 days 2,500 gives you 11k. Good deal
