We don't board our horse, so I 'm not really sure on that cost. We have 2 horses that we board here for a family, but we don't charge them money, they help with upkeep and other yard work for us in exchange.

Food cost is a bit higher in the winter than in the summer. My husband actually does the budget so this is pretty roundabout. I think we spend about $30 a week in the summer and closer to $50 in the winter. That's for feed and hay.

There's also other regular expenses. Shavings for the stall, wormer, vaccinations, farrier expenses, bug spray, etc.

Then there are expenses that are less often, but you'll need to replace every now and again, like water and food buckets, grooming supplies-brushes, etc.

There's also "one time" expenses like tack.

Also are you going to take lessons?
