Netflix account premium version?

I plan to increase my Netflix account from Standard to Premium.

If I have already paid for this month and buy the premium version, then I have to pay 16 euro or only 4 euro more for this month.

The premium version will not apply until next month.

and from next month you have to pay the 16 euro

Does that mean that if I buy it now, I can't have it yet?
