Seven Day Yield

DEFINITION of 'Seven Day Yield'

Interest earned on a money market mutual fund without the compounding interest. This yield is the dividend and interest earned by the fund, and paid out during the seven-day period, minus any management fees incurred during those seven days. Also referred to as the seven-day annualized return.

BREAKING DOWN 'Seven Day Yield'

For example, let's say one share of the fund was $18 in the beginning of a seven-day period, and $18.05 at the end of that same seven-day period. Fees for that week were 3 cents.
