Just feeders, New bulbs every six months & gutload for feeders. Your looking at over $200 a year. Vet costs are different everywhere so its hard to say how much that would be.
It depends on what you buy but you can go through the list, tally up what applies to your situation, and get a rough estimate. Starting up is the most expensive part, since you're buying everything from scratch, but how much you spend every year afterwards will depend on whether you breed or buy feeders, how many you get, if you have any vet visits, changing UVB bulbs, etc.
Once you are set up you will mainly need feeders, gut load, chance your lights every six months and vet bills. You can get 500 crickets shipped from Lazy H cricket farm here in FL for $15.00 and if you start with a tad on the small size and keep them clean and well fed they will last you 3 to 4 weeks. You can also get super worms there. I'm not sure about the price of 500 because I always get 1000 and they are $15.00 shipped and 500 will last you 6 to 8 weeks. You are going to have some die off in both but this is way cheaper that buying at the unsanitary pet stores. You are going to want to feed a large variety of feeders and you can get a colony of Discoids (roaches) going. They are legal here in FL. He may or may not eat those. Some of my chams like them and a few do not. You'll also want to order hornworm or silkworms once every month or so and shipped they will cost you around $30.00. You can get butter worms for around $20 shipped and you'll want to offer a veiled fresh veggies and fruits. You will want to buy a good temp gun and down the road you will definallely want to get a UV meter. If you do everything right and are able to keep your guy healthy you will only need well check ups and fecals 2 to three times a year. You can call the vet I gave you in your other thread to see what they charge for that. My vets charge anywhere from $50 to $65 for a check up and $17 to $25 for a fecal. Fecals are very important because chameleons often get parasites.
I'm sure there's more but that's all I can think of right now. I would recommend you buy form a small time breed that really cares about their animals. I believe I recommend one to you in another thread. It's much easier for a new keeper to start with a nice healthy animal. I'm attaching my blog for new keepers for you. I hope you will find it helpful. https://www.chameleonforums.com/blo...-keepers-young-veiled-panther-chameleons.html
