My network is 192.168.30.0/24, if I want subnet to 8 networks.  Based on my calculation, the result should be this... 192.168.30.0/27.  Is it correct?

Onther way to look at this is, you have a /24 "supernet".  If you want 8 subnets, you need 2 [to power 3 = 8] meaning add 3 (the power factor) to your "supernet" mask (which is 24).  That will give you a /27.
