If you use the VESTS method, it will delegate SP to the new account. You dont lose delegated SP, its just used by the account that its delegated to.
If you use the STEEM method it will transfer the STEEM to the new account and power it up. This takes a 30 day withdrawal period. But again, you dont lose it, the new account gets it.
The account creation cost is 0.200 STEEM and is required.
It depends what you mean by cost.
