I recently read that the average cost per child to homeschool was $500. So $1300 for 3 kids has you below average. I'm not sure what I spend on my son. Maybe $40 per month, tops. I'm including gas to go to park days in that figure. So that's about $360 for 9 months. Probably 3/4 of that is gas and 1/4 is for activity fees. None is for curriculum.
ETA: I probably save that much money on clothes. Since ds is homeschooled, he doesn't need as many. He can stay home if his shoes are wet. Since he doesn't see the same people each day, he doesn't need to have as much variety just so that they don't comment about his wearing the same few clothes over and over. He can have just one pair of shoes, a few pants, and a half dozen t-shirts. I also save money because we don't have to participate in fund raisers or buy a list of specific school supplies that we wouldn't ordinarily use (lysol wipes, kleenex, etc.) In addition, I probably spend less on lunch at home than I would if I had to pack food. There is also less "keeping up with the Joneses." Ds is less likely to want things that are a fad or want a gadget (or clothing style) that all of his friends have.
