I use a small portion of 3 acres of land for my gardens, orchard, aquaculture pond, and livestock. I do not have any debt at all and only need to pay taxes and scant utilities per month. A small portion of taxes is negated via a farm tax since my small farm is registered as such. A small portion of the utilities are used for maintaining farm/garden-related things (electric for light, heat, and water pump).
Plant-based costs are rather low, but I do spend extra money on that just for experimentation. The largest cost for plants is for infrastructure elements & maintenance like fencing to keep varmints out, replacing pots/trays, grow lights & their electric use for early season plant starts, replacing polytunnel plastic, and replacing older fruit trees. Animal-based costs are completely different. There's utility usage (light/heat/water pump), some feed costs (depending on animal type), infrastructure (repairs/additions,) predator traps, fencing, and so on.
I also make a small amount of income from the plants and animals in the form of currency, services traded, and goods traded. I consider all money spent on the farm as my monthly food bill. If I were to buy all my food instead of grow/raise/local trade all my food then the cost would be slightly less in currency. However, I do this for my health; body, spirit, and mind.
I spend about $300-$350/month on my small farm. Keep in mind that I'm always trying to add new infrastructure to make long term things easier. I need a larger coop, more fencing, more raised beds, etc.
I fucking love it.
