Anyone asking how much do iguanas cost is usually pricing the animal, not the setup behind it. That makes sense at first glance. A hatchling iguana at a reptile show often costs less than a nice dinner out.

The problem is that an iguana does not stay small. Within two or three years it can reach three to five feet long. A full grown male can push six feet nose to tail.

Cost grows with that size. Most new owners underestimate the curve badly. That is one reason so many iguanas end up surrendered or rehomed once they hit adult size.

How much is an iguana to buy

Baby and juvenile green iguanas are widely available. Reported hatchling prices commonly run from around $10 up to about $200. The exact number depends on the seller, the animal’s size, and local demand.

Older juveniles, roughly three to five feet long, often cost more than hatchlings. They have already survived the riskiest early months. Rarer iguana species, such as rhinoceros iguanas, sell for several hundred dollars and are a different animal from the common green iguana.

Price also shifts with where the animal comes from. A private breeder who has handled and fed the iguana from hatching often charges more than a bulk importer or a generic pet chain. That higher price can mean a calmer, healthier start.

Adoption is the other route. Rescues and exotic pet amnesty events regularly take in adult iguanas whose owners underestimated the size. Adoption fees are usually well below breeder prices, and an adopted adult skips the years of enclosure upgrades.

Whatever the sticker price, treat it as a rounding error. Veterinary care sheets describe the species as at least a 10 year commitment and a hefty financial investment. Nearly all of that investment goes to housing, lighting, and food, not the animal.

Setup cost: enclosure and lighting

An adult green iguana needs a large custom enclosure, not a standard glass tank. Full grown iguana housing starts at the 6 by 3 by 6 foot minimum that LafeberVet gives for adults, and many keepers build to about 10 by 5 by 6 feet.

Very few keepers buy this off the shelf. Most build it themselves, and that is where the cost range gets wide. A small premade cage, sized for a young iguana, might run $100 to $300, but it is only a stopgap.

A properly sized adult enclosure, whether custom built from wood and mesh or a walk in room conversion, commonly lands between $800 and $4,000. Materials, size, and whether a contractor builds it all move that number.

Add it up and most keepers spend $1,200 to $4,500 to properly house an adult iguana the first time. Heating and lighting needs and humidity needs both push toward the higher end.

A big enclosure rarely runs on one heat source. It usually needs more than one basking bulb and more than one UVB fixture, such as the Arcadia ProT5 Kit Desert 12%, to cover the whole space evenly. That raises both the setup cost and the monthly bill.

Monthly costs: food, electricity, and UVB replacement

Once the enclosure is built, costs settle into a fairly predictable monthly pattern. Daily iguana care revolves around fresh vegetables and greens. Iguanas are strict herbivores that eat far more plant matter by volume than most reptiles.

Electricity: a worked example

The electricity line is the one you can calculate rather than guess. A typical adult setup runs a 150 watt basking bulb, a 100 watt flood bulb, and a 54 watt T5 HO UVB tube for 12 hours each. Add a 100 watt ceramic heater for about 8 hours on cool nights, and the total is roughly 4.4 kilowatt hours a day, or about 130 kWh a month.

At the 2025 U.S. average residential rate of 17.3 cents per kWh, reported by the Energy Information Administration, that is about $23 a month. The same setup costs about $11 in North Dakota (8.2 cents) and about $47 in Hawaii (35.7 cents).

A room sized enclosure with two or three basking zones can double those figures.

UVB bulbs are a cost that catches new owners off guard. Output drops well before a bulb visibly dims. Most care guides recommend full replacement about every 6 months regardless of how the bulb looks.

Budget $30 to $100 twice a year for fresh UVB tubes or bulbs, on top of the monthly totals above. Electricity also tends to climb in winter, since basking and UVB fixtures run longer to hold daytime temperatures.

Put together, most keepers land around $50 to $150 a month for an adult iguana, before any vet costs. That works out to roughly $700 to $1,800 a year in ongoing care.

Vet care and health reserve

An annual wellness exam for an iguana, including a fecal parasite check, commonly runs $40 to $135. The exact price depends on the clinic and the region.

Reptile literate vets are not evenly spread out. Some owners drive well outside their area to find one, and that travel is its own hidden cost of ownership.

The bigger risk is an emergency. Treatment for a serious illness, such as an abscess or metabolic bone disease, can run well over $1,000. Imaging and medication both add to that total.

Common iguana health problems are largely preventable with correct UVB, calcium, and diet. That is one more reason the lighting and food budget above is not optional spending.

A reasonable approach is to set aside $200 to $300 a year purely as a health reserve, separate from the routine wellness exam. Most years that money goes unused.

The years it is needed, an owner without it faces a hard choice. That choice is between an unaffordable bill and an animal in pain.

Lifetime cost of owning an iguana

Green iguanas commonly live 10 to 16 years in captivity. Well cared for animals have reached 15 to 25 years. That long lifespan is the real answer to how much an iguana costs over time.

A decade or two of monthly bills adds up to far more than the setup ever did. This is why the purchase price question, on its own, misses most of the real commitment.

Those lifetime figures are built from the setup and monthly ranges above, not a single published total. No authoritative source publishes one exact figure for iguana cost, and sources differ on almost every line item.

Treat the ranges as planning numbers, not a fixed bill. For general reptile budgeting outside these iguana specific numbers, the site’s lizard cost of ownership guide compares these categories across species.

Other costs to plan for

A few smaller items rarely make it into the main iguana cost total but still add up. A sturdy harness and leash for supervised outdoor time runs $15 to $30. A digital kitchen or postal scale for weighing the animal costs another $10 to $20.

A humidifier or fogger, useful for keepers whose homes run dry, typically costs $40 to $80. A dedicated travel carrier for vet visits adds another $30 to $60, and it is worth buying once rather than improvising each trip.

None of these items are required on day one. They are worth budgeting for once the core enclosure, lighting, and food costs above are already covered.

Florida: permits and iguana removal cost

In Florida the cost question runs the other way. Green iguanas have been on the state’s Prohibited Species List since April 29, 2021, so they cannot be acquired as pets there. Owners who already had one needed a permit to keep it, and the Exotic Pet Amnesty Program takes surrendered animals without penalty.

Homeowners dealing with wild iguanas pay private removal companies rather than the state; there is no public bounty. Fees vary by company and by the number of animals trapped. Our green iguana habitat page covers the Florida population, the rules on removal, and what cold snaps do to wild iguanas.

How much does an iguana weigh

Size is worth knowing alongside cost, since a bigger animal drives bigger enclosure and food bills. An adult green iguana typically weighs 4 to 8 kilograms, or roughly 9 to 18 pounds, with males running larger than females.

Males and females also differ in length. Males commonly reach 6 to 7 feet, and females rarely pass 5 feet.

That weight and length builds up gradually over two to four years, not overnight. This is exactly why so many owners start with a small enclosure and then face a second, bigger bill once the iguana outgrows it.

Planning for the adult size from day one is usually the cheaper path. It also avoids the stress of moving a large, established iguana into an unfamiliar new enclosure.

Frequently Asked Questions

How much does an iguana cost to buy?

A baby green iguana typically costs $10 to $200 depending on the seller and the animal’s size. That price is a small fraction of what the enclosure, lighting, and ongoing food will cost over the animal’s life.

How much does a full iguana setup cost?

A properly sized adult enclosure with heating and UVB lighting generally costs $800 to $4,000 or more. Combined with the animal and the first months of food, most new owners spend $1,500 to $4,500 in the first year.

How much do iguanas cost per month?

Monthly costs for food, electricity, substrate, and supplements typically run $50 to $150 once an adult iguana is set up. Electricity alone is about $23 at the U.S. average rate, and UVB bulbs add another $30 to $100 roughly twice a year.

How much does an iguana weigh?

Adult green iguanas usually weigh 4 to 8 kilograms, or about 9 to 18 pounds. Males tend to be heavier and longer than females of the same age.

Is an iguana expensive compared to other pet lizards?

Yes. The purchase price is low, but the space and food an adult iguana needs make it expensive to house. Its adult size is the main reason.

Do iguanas need ongoing vet care?

An annual wellness exam with a reptile literate vet is recommended and commonly costs $40 to $135. Setting aside an extra $200 to $300 a year as an emergency reserve is a reasonable safety margin.
