Effective rate for period = (1 + annual rate)^(1 / # of periods) - 1

So for monthly, quarterly, and semiannual rates, the math becomes:
Monthly rate = (1 + annual rate)^(1/12) - 1
Quarterly rate = (1 + annual rate )^(1/4) - 1
Semiannual rate = (1 + annual rate)^(1/2) - 1
Similary:
Daily rate = (1 + annual rate)^(1/365) - 1
or
Daily rate = (1 + annual rate)^(1/366) - 1
Depending on which year we are analyzing.
