You have to give more specific details (country/state,marital status etc.) before a reasonable answer can be provided. But to give you a general idea, being self employed in the US can cost anywhere from $100-$1000 per month depending on how kind of insurance you need/want with deductibles, co-insurance limits, out of pocket expenses, in-network vs. out-network etc.

In my case, I use my wife's health insurance from her job and don't bother buying it myself.If I had to, it would probably cost me at least $500 per month.
