We got Micki and my RB cat Lucky fixed for free...our humane society does an annual spay/neuter program, granted, we had to drive all the way to the humane society in a snowstorm but it was worth it. For normal neutering they charge $50-$75 and to spay a female its generally a little more expensive. We haven't gotten Kyra spayed yet, our vet told us that he wouldn't do it, he wants us to take her to MSU because she is supposedly at "high risk" because of her cleft palate. We called them and they will charge us over $200 to spay a 8 pound dog! But yeah, there are some places that do low cost spay/neuters.
