Everyone's take home pay will be different. Figure out how many spots you can fill, your daily/weekly/monthly rate (however you are going to charge) and go from there. It should hopefully take no longer than a month or two to be full but of course this all depends on the need in your area.

Every year I try to increase my expenses so it decreases the amount I have to pay taxes on. It hasn't worked yet lol. I am going to try soooo hard not to coupon for daycare. It saves me money monthly but I need higher grocery receipts!! I have young children and they don't eat a lot in one sitting though.

We don't have a mortgage so we can't claim the interest paid on that but we do have a car loan and will be able to claim that this year so hopefully that helps!
