How Much Does a Green Iguana Really Cost?

Green iguanas are cheap to buy as babies, and that low starting price is exactly what leads so many owners to underestimate what they're taking on.

The iguana: $20 to $1,000+

Baby green iguanas are farm-raised and inexpensive, commonly $20 to $100. Color morphs push the price up considerably. Albino, hypomelanistic, axanthic, and purple translucent lines commonly run $300 to $1,000 or more. A related but different, IUCN-endangered species, the blue iguana, can run into the tens of thousands. Worth noting so you don't confuse the two when shopping.

First-year kit: about $985 to $1,100

This is the working box for a growing juvenile, plus the heat, UVB, and humidity gear that carries over to the adult enclosure. Nothing on this table is the walk-in. That is a second purchase.

Add those rows and the kit lands at about $1,041 to $1,105. Lighting and the mister move with the animal into the adult enclosure, so that spend is not thrown away.

Adult enclosure: a second purchase

The hatchling setup and the adult enclosure are two different purchases a year or two apart. Price both on the day you buy the lizard.

Prices last checked September 2026 at Pangea Reptile, Reptile Basics, Toad Ranch and Zen Habitats. Retail prices move; treat the table as a snapshot, not a quote. The added kit rows use the Amazon bands already in the site gear list.

An adult is 6 feet or more including the tail and needs a 6 by 3 by 6 foot arboreal enclosure at a floor, with 10 by 5 by 6 as the working minimum. The two ready-made boxes on that table reach 6 or 8 feet long but stop at 2 feet deep and 4 feet tall, so they miss the floor. You can buy a box. You cannot buy one that meets the minimum. The first enclosure that meets 6x3x6 outright is a made-to-order box at $3,740, and nothing ready-made reaches 10x5x6, which is walk-in territory. A walk-in build from plywood, welded mesh, and hardware runs several hundred dollars in materials. A custom builder starts around $1,000.

Ongoing costs: roughly $60 to $150 a month

Fresh produce, supplements, substrate, and electricity to run heating and lighting for a large enclosure add up higher than most pet reptiles. Produce alone commonly runs $30 to $50 a month, with electricity adding another $20 to $50. Some of that salad can be grown or foraged instead of bought, and the safe weeds and wild plants list covers what is safe to pick.

Vet costs

Reptile vets are specialized, and iguana-specific issues, metabolic bone disease treatment or egg-binding surgery among them, can run into real money. Budget for an annual exam at minimum, and know that emergency care for this species tends toward the expensive end.

Lifespan: 15 to 25 years, if the iguana survives its first year

With excellent care, green iguanas live 15 to 20 years, sometimes 25. Inadequate diet, lighting, and housing are so common in this species that an estimated 70% of captive green iguanas die within their first year of life. The low purchase price has nothing to do with what it costs, in setup and in animal welfare, to keep this species alive long-term.

What the budget comes to

A green iguana's sticker price is almost irrelevant to what responsible ownership costs. This is one of the more expensive reptiles to house correctly, and the setup is the difference between an iguana that reaches 20 years and one that does not survive the first. If you're weighing this against another large lizard, the savannah monitor and the Argentine tegu are similarly demanding, with an omnivorous diet instead of a strictly herbivorous one.
