How to read these numbers
No veterinary organization publishes running costs for this species, so every price below comes from a retailer listing we fetched and recorded on 3 September 2026, with the retailer named. Prices move and promotions end. Use these as calibration rather than as a quote.
The sourced summary of what actually recurs: Documented recurring expenses (no allowed-tier prices published): UVB bulb replacement every 6-12 months, substrate replacement, feeder insects plus fresh greens/vegetables, calcium powder dusted 2-3x/week and multivitamin every two weeks, reptile-safe disinfectant, and electricity for continuous heating and 10-14 h/day lighting.
Feeder insects: the biggest variable
Insect spending depends almost entirely on age, because feeding frequency collapses as a dragon matures.
Hatchlings: Hatchlings (under 1-2 months) should be fed 2-3 times daily, primarily appropriately sized live insects (flightless fruit flies, gut-loaded pinhead crickets, mashed vegetables)
Juveniles: Juveniles 1-4 months old should be fed twice daily (crickets, veggies, occasional super/mealworm)
Sub-adults: From 4 months to adulthood, feed once daily; NCSU lists crickets, super/mealworms, pinky mice, and salad every other day for this stage.
Adults: Adult bearded dragons can be fed every day or every other day; VCA notes adults may only eat every 24-72 hours since they are no longer growing.
A hatchling eating several times daily consumes many times what an adult does. That is why cost guides quoting a single monthly figure are misleading: the first year is expensive and it settles afterward.
The prices we verified: Dubia roaches listed at 7.99 US dollars for 25 small, 9.99 for 25 medium, and 17.99 for 50 medium.
Also: Live crickets listed at 17 cents each up to 35, dropping to 14 cents each at 76 or more.
And for variety: Mealworms listed at 2.99 US dollars for 50 and 13.99 for 500; superworms at 8.99 for 50; hornworms at 9.99 for 4.
For very young dragons: Flightless fruit flies listed at 8.99 US dollars for a 16 ounce culture.
One way to cut this substantially is a self-sustaining dubia colony rather than repeat purchases, which the dubia guide covers alongside the legal restrictions in some regions.
Greens and vegetables
This line comes from your supermarket rather than a pet shop, which keeps it cheap. The staples: Calcium-rich staple greens include collard greens, mustard greens, turnip greens, and dandelion greens.
A bunch of collard or mustard greens feeds a dragon for several days, and the plant portion grows as a share of the diet with age: Diet shifts with age: hatchlings/young juveniles eat roughly 70% insects / 30% vegetation, flipping in adulthood to mostly vegetation (RSPCA Australia: adults ~90% vegetation / 10% animal matter; PetMD: adults 70-80% plants)
So the two main food lines move in opposite directions. Insects fall as greens rise, and greens are the cheaper of the two.
We did not verify supermarket produce prices, since they vary by country and season more than any pet product. Budget for a few bunches of greens a week and a rotating supporting vegetable, per the vegetable guide.
Supplements
Calcium and multivitamin powders last a long time, so the monthly share is small even though the schedule is frequent.
Juveniles: 4 to 5 times a week
Adults: 1 to 2 times a week
Multivitamin: Dust feeder insects with a reptile multivitamin powder 1-2 times per week (PetMD diet guide) or once weekly (PetMD care sheet); RSPCA applies multivitamin powder to vegetables every two weeks.
We could not retrieve current supplement prices from the retailer pages we fetched, so we are not printing a figure. A container typically lasts months rather than weeks. The calcium guide covers the schedule.
UVB bulbs, amortised
This is the recurring cost owners most often leave out of a monthly budget, and it is not small.
Replace UVB bulbs on schedule even if still emitting visible light: every 6 months (NCSU, VCA, PetMD); WSU: every 6-8 months for juveniles, yearly for adults; Merck: fluorescent every 9-12 months; RSPCA SA: effective UVB lifespan typically 6-12 months - follow manufacturer guidance.
The price we checked: Zoo Med T5 High Output 10.0 UVB lamp listed at 23.98 US dollars, from a regular 24.99.
Two replacements a year spread across twelve months is a real monthly line, and skipping it is the most consequential saving anyone makes, since it leads directly to the disease covered in the MBD guide.
Basking bulbs fail on their own schedule: Zoo Med Repti Basking Spot lamp listed at 13.98 US dollars for a 150 watt bulb and 19.98 for a two pack; an Arcadia GoldenSun halogen basking lamp listed at 7.69.
Electricity
A basking lamp and a UVB tube running 12 hours of light a day every day is a continuous draw. In colder rooms, a night heat source adds to it, since temperatures should not fall below no colder than 65 to 70 F (18 to 21 C).
We cannot give a figure here honestly. Electricity tariffs vary enormously by country and by supplier, and wattages vary by setup. What we can tell you is the equipment involved: Heat the basking zone with a 60-100 W reflector bulb (RSPCA UK) or reptile-specific flood/spot lamp on a thermostat (RSPCA SA); ceramic (non-light-emitting) heaters maintain night temperature.
Multiply your own tariff by the wattage of your lamps for a real number rather than trusting a figure from a site that does not know where you live.
Veterinary care
Not monthly, and it belongs in the annual budget: A veterinary wellness examination once every year is recommended for bearded dragons.
For new arrivals: A reptile-experienced veterinarian should examine a new bearded dragon within 48 hours of purchase (physical exam, weight, oral cavity, skeletal evaluation, fecal parasite test)
Reptile and exotic clinics charge more than general practices, and fees vary too widely by region for a published figure to be useful. Call two local reptile vets and ask their exam fee. Then keep a reserve, because the health section covers conditions that arrive without notice.
The monthly picture
| Line | Notes |
|---|---|
| Feeder insects | Largest and most age-dependent line |
| Greens and vegetables | Supermarket produce; grows as a share with age |
| Supplements | Small monthly share; containers last months |
| UVB bulb, amortised | Two replacements a year |
| Basking bulb | Replaced as it fails |
| Electricity | Continuous; depends on your tariff |
| Substrate | Paper-based options are inexpensive |
| Vet care | Annual exam plus a reserve |

Where you can and cannot economise
Reasonable savings: a dubia colony instead of repeat purchases, paper-based substrate instead of specialty products, supermarket greens instead of packaged reptile food, and buying supplements in larger containers.
Do not economise on: UVB replacement, correct enclosure size, thermostat-controlled heat, or veterinary care. Those four are what separate a dragon reaching 7 to 15 years from one that does not.
The honest framing is that ongoing costs are manageable and permanent: Budget for a 10-15+ year commitment (RSPCA UK: 'their lifespan is usually 10 to 15 years or more, so they're quite a commitment')
The setup cost guide covers the one-time spending, which is the larger number by a wide margin.
