Service tax nil interest for delay/min interest payable

Do we need to pay interest on swachh bhart cess for 6 days delay.

Swachh Bharath Cess : Rs.107

Due date : 06/01/2016

Delay : 6 days

Interest @ 15% ,being a P. Ltd company with foriegn Turn Over  2crore but domestic T.O is only Rs.12 lacs. So using 3% concession SBC interest is only 22 paise. But using a excel for service tax interest calcultor- interest payable on above is Nil.

Is there any minimum interest payable

Please comment.
