The cost to host a home poker game is broken into 2 groups: mandatory costs (for things you need), and optional costs (for things you don't need). You can check out my home poker game spreadsheet if you want a calculator to see how much the game will cost you over the long run.
The only mandatory costs are the costs for the cards and the chips. You can get regular cards (i.e. Bicycle playing cards) for $2 per pack. More expensive Kem cards will cost about $15. Poker chips will run you about $20 for a set of $300 to $40 for a set of 500. These are for used poker chips. In my opinion, there is no need to buy new chips.
Some poker game hosts will also put out food for people. If you do this, it will probably cost about $10 per night. But this is entirely optional.
A good used poker table may cost you about $50-$100 depending on the quality. Many casual games are just played on a kitchen table that doesn't cost anything.
