Seems like you haven't understood the system yet even though hosseinimr93 has explained it above, and id5000 has shown you the calculation. Freebitco team has mentioned this in the premium membership page

They have said about the increase of the 4.08% interest rate by the 'X' percentage. The 7.5% increase of 4.08 is: (7.5÷100) × 4.08 = 0.306%. It has been rounded up to 0.31%. Therefore, your interest boost amount is accurate there. Try to understand the system properly.
Firstly thanks for your example. Please correct me If I understood something wrong. Thats why I am here. What can easily be misunderstood is that there is a difference between Annual and Daily Interest separately calculated.
I understand the value in brackets (0.31%) is the so-called Bonus Interest for FUN holders that is already included in the value before the brackets (4.39%).
To get the
Daily Interest calculated based on the
Annual Interest 4.39% (Bonus of 7.5% already included) then I result in 0,0121944444 and not 0.01178082%.
My calculation is 4.39/360=0,0121944444 to get the daily interest. But on my EARN BTC tab is just @ 0.01178082% * per day given..
