How Much Does Gerbil Ownership Really Cost?
On This Page▾
Gerbils are one of the more affordable small pets, with one important caveat: like the degu, you're budgeting for two animals, not one.
The Gerbil: $5 to $50 Each
Most gerbils run $10 to $20 at a typical pet store, with adoption often landing at $10 or less, sometimes including a starter cage. Since this species must be kept in same-sex pairs or small groups, plan for at least two from the outset.
Upfront Setup: $165 to $350
| Item | Cost Range |
|---|---|
| 20-gallon long aquarium (terrestrial setup) | $35 - $80 |
| Secure mesh lid | $35 - $45 |
| Solid exercise wheel (10-12 in) | $20 - $40 |
| Hideouts and tunnels | $5 - $30 |
| Water bottle and food dishes | $5 - $15 |
| Digital thermometer | $10 - $35 |
| Two bags of paper-based bedding, enough for 6 to 10 inches (check the quantity against your tank's floor) | $30 - $60 |
| Hay, worked into the bedding to hold tunnel shape | $15 - $30 |
| Chinchilla sand for a sand bath | $10 - $15 |
| Setup total | $165 - $350 |
Typical price ranges across retailers.
A glass tank is the main expense here, not a wire cage, along with genuinely deep bedding, a solid exercise wheel, hides, and chews. A single gerbil's setup runs toward the lower end of this range, a properly housed pair toward the higher end.
Ongoing Costs: Roughly $10 to $20 a Month
Food and bedding make up nearly the entire monthly cost:
| Item | Annual Cost |
|---|---|
| Bedding | $20 - $30 |
| Hamster pellets or lab blocks | $5 - $15 |
| Grass hay (unlimited) | $20 - $25 |
| Sand bath (chinchilla sand) | $5 - $15 |
| Chew toys (smaller, softer) | $5 - $15 |
| Exotic vet check | $60 - $130 |
Typical price ranges across retailers.
Spot-cleaning rather than full bedding changes stretches this further, a genuinely low-maintenance species financially.
Sexing, and What an Accidental Litter Costs
The cheapest line in the budget hides the most expensive mistake: a "same-sex pair" that is not. Sexing works on the gap between the anus and the genital opening, short in a female and clearly longer in a male, and in young gerbils that gap is the most reliable guide there is. Adult males also run heavier, about 80 to 130 grams against 70 to 100 for females, and they develop the scent gland on the belly earlier and larger. Ask the seller to show you the difference on the animals you are buying, then check again at home.
A wrong call compounds fast. Males are mature at 70 to 84 days, and females about a month after their vaginal opening appears at 40 to 60 days. Pregnancy lasts 24 to 26 days, litters run 3 to 7 pups, and the pups are weaned at around 25 days. A female can conceive again while still nursing, with that next pregnancy running 27 days or more, so one mixed pair can turn out a litter roughly every month. Every pup then needs sexing, a same-sex group, and a home. Each extra group needs its own tank and lid, which is $75 to $120 before bedding, going by the table above.
Vet Costs
You'll want an exotics-experienced vet. Scent-gland tumor removal is the most common surgical cost in this species, and because gerbils are small, health problems can progress quickly, prompt vet visits matter more than they might for a larger animal.
Lifespan
2 to 3 years is the normal lifespan for this species.
Shorter than a degu, but still a genuine multi-year commitment worth planning for rather than treating as disposable. A gerbil bought as a "starter pet" for a child is still, on average, a two to three year relationship.
The Honest Budgeting Takeaway
Gerbils are inexpensive individually and inexpensive to maintain, the adjustment for first-timers is the tank itself. A proper glass enclosure with deep digging substrate costs more upfront than the wire cages often marketed for small rodents, but it's the right choice for how this species lives. Guinea pigs trade that digging depth for floor space instead, which changes which room a setup fits in. The closest comparison is the degu, another social, day-active rodent bought in pairs, though with a longer lifespan and a larger cage. Two Pets Where You're Really Buying a Pair sets the two side by side.

Frequently Asked Questions
How much does a gerbil itself cost?
$10 to $20 is the usual pet store price, and adoption often runs $10 or less, sometimes with a starter cage thrown in. They have to live in same-sex pairs or small groups, so plan on at least two.
What does a full gerbil setup cost upfront?
Roughly $165 to $350. The big line is a glass tank instead of a wire cage, and after that come deep bedding, a solid exercise wheel, hides, and chews. One gerbil lands near the bottom of that range, a properly housed pair near the top.
What are the ongoing monthly costs for gerbils?
Roughly $10 to $20 a month once the annual supply costs are spread out, almost all of it food and bedding. Spot-cleaning instead of full bedding changes stretches that further, which makes this a cheap species to run.
How much does gerbil vet care cost?
You'll want an exotics-experienced vet. The most common surgical cost in this species is removing a scent-gland tumor, and since gerbils are small, problems can progress fast, so a prompt visit matters more than for a larger animal.
How long do gerbils live?
2 to 3 years. Shorter than a degu, but a gerbil bought as a starter pet is still a multi-year commitment.
