If my LLC is loosing money, how much of that pes through to your own earnings?

If I form a LLC and I spend over 7000 dollars in marketing, rent, technology and other costs, how much will be ped through to my taxes? If I earn 30G a year and get taxed 5G, how much do I expect to get back? Do I get back the whole 5000G in my tax return or just part of it?
