Sec. 230.7  Payment of interest.

    (a) Permissible methods--(1) Balance on which interest is 
calculated. Institutions shall calculate interest on the full amount of 
principal in an account for each day by use of either the daily balance 
method or the average daily balance method.\1\
---------------------------------------------------------------------------

    \1\ Institutions shall calculate interest by use of a daily rate of 
at least \1/365\ of the interest rate. In a leap year a daily rate of 
\1/366\ of the interest rate may be used.
---------------------------------------------------------------------------

    (2) Determination of minimum balance to earn interest. An 
institution shall use the same method to determine any minimum balance 
required to earn interest as it uses to determine the balance on which 
interest is calculated. An institution may use an additional method that 
is unequivocally beneficial to the consumer.
    (b) Compounding and crediting policies. This section does not 
require institutions to compound or credit interest at any particular 
frequency.
