How Much Does Spaying or Neutering Cost?

Spay and neuter costs in the U.S. span an unusually wide range — commonly anywhere from about $50 at a subsidized clinic to over $800 at a full-service veterinary hospital, depending on your pet's species, sex, size, and above all, where you live and what type of clinic you use. This is a sourced breakdown of what the procedure actually costs, why the range is so wide, and where to look if cost is the main barrier.

Dog Spay and Neuter Costs

Two sourced figures worth putting side by side, because they illustrate just how much this varies by dataset as well as by clinic. CareCredit's 2026 pricing guide, reviewed by a board-certified veterinary practitioner, states: "The national average cost for spaying a dog is $455, with a range of $361 to $829. The average cost of neutering a dog is $487, with a range of $385 to $885." A separate published price guide (Pawlicy Advisor, also reviewed by a licensed veterinarian) put dog spay costs at roughly $400–$800 and dog neuter costs at roughly $300–$700 — a range that puts spaying somewhat above neutering, which lines up with the general expectation that spaying (an abdominal ovariohysterectomy) is a more invasive procedure than neutering (a simpler, more externally accessible surgery) and is often — though not universally — priced higher at an individual clinic. CareCredit's national average shows neutering slightly higher than spaying, which the source doesn't explain and likely reflects how its data was aggregated across many providers and regions rather than a claim about surgical complexity. The honest takeaway: expect somewhere in the broad $300–$900 range at a full-service veterinary practice, confirm the actual price with your own vet's office, and don't treat either published average as a quote for your specific dog.

Cat Spay and Neuter Costs

Cat procedures are consistently cheaper than dog procedures, reflecting less tissue and a shorter, simpler surgery overall. Based on Pawlicy Advisor's published veterinary cost guide, cat spaying typically runs $200–$600 and cat neutering typically runs $50–$400 at full-service veterinary practices in the U.S. — with, again, spaying (the more invasive of the two procedures) generally priced at the higher end relative to neutering. As with dogs, low-cost and nonprofit clinics can charge well below these full-service ranges for both sexes.

Why the Price Swings So Much by State and Clinic Type

CareCredit's state-by-state breakdown makes the regional gap concrete: the lowest average costs in its dataset were in Mississippi and West Virginia, both landing in the roughly $367–$393 range for spay or neuter, while the highest were in Hawaii, averaging roughly $814–$874, with Massachusetts also running well above the national average at around $635–$685. That's more than a two-to-one difference for what is, medically, a similar procedure — driven mainly by regional cost-of-living and clinic overhead (staff wages, rent, equipment) rather than any difference in the surgery itself.

Clinic type matters at least as much as geography. A full-service veterinary hospital — the same practice you'd use for annual exams and sick visits — typically charges more than a dedicated low-cost or nonprofit spay/neuter clinic, partly because the hospital's overhead and staffing model is built around a broader range of services, not high-volume, single-procedure surgery days. Low-cost and nonprofit clinics, by contrast, are often specifically structured to bring the price down through high patient volume, external funding, or a narrower scope of services around the surgery itself.

Low-Cost and Subsidized Options

If cost is the main barrier, it's worth actively looking for a subsidized option rather than assuming only full-price veterinary surgery is available. The ASPCA maintains and points pet owners toward the SpayUSA database to help locate lower-cost providers by location, and operates its own low-cost spay/neuter services directly in select regions, including New York City, the Los Angeles area, and western North Carolina. Many local humane societies and animal shelters also run their own low-cost or mobile spay/neuter clinics, sometimes open to the public regardless of whether the pet was adopted from that organization — worth a direct call to your local shelter even if you didn't adopt through them. Costs at these clinics can run well below full-service veterinary pricing, though exact figures vary by organization, location, and funding availability, so confirm current pricing directly with the specific clinic rather than assuming a fixed number applies everywhere. Some clinics also limit eligibility by income, location, or species, so it's worth calling ahead to confirm your pet qualifies before counting on a specific low-cost date.

Does Your Pet's Age or Size Affect the Price?

Yes, in both directions. Larger dogs generally cost more to spay or neuter than smaller dogs at the same clinic — more tissue, more anesthesia by body weight, and typically a longer procedure — which is part of why the published ranges above are wide enough to cover everything from a small-breed dog to a giant breed in the same figure. Age matters too, though less predictably: a healthy young adult is usually the most straightforward, lowest-cost surgical candidate, while an older pet may need additional pre-surgical bloodwork to confirm anesthesia safety, adding to the total even before the surgery itself. The right age to spay or neuter a specific pet is a question for your veterinarian, not a cost article — it depends on breed, size, and individual health factors that a general guide like this one can't evaluate.

What's Usually Included — and What Isn't

Published pricing guides consistently note that the quoted procedure cost doesn't always represent the full bill. Common additions to budget for:

• A separate office visit or exam fee — CareCredit's guide specifically flags that a clinic may charge an "in-office visit" fee in addition to the surgical procedure cost.
• Pre-surgical bloodwork, especially for older pets, to confirm they're a safe candidate for anesthesia.
• Pain medication to send home for recovery, sometimes bundled, sometimes billed separately.
• An e-collar or recovery suit to prevent licking or chewing at the incision site.
• Complication surcharges — a female pet who is pregnant or actively in heat at the time of surgery is a more complex, longer procedure at most practices, and is commonly priced higher than a routine spay.

Ask for a full written quote before the day of surgery, specifically confirming what's bundled into the headline price versus billed as an add-on — the same advice that applies to routine and emergency veterinary costs generally, covered in more detail in our guide to what a vet visit costs.

How This Fits Your Broader Budget

Spay/neuter surgery is typically a one-time cost, usually incurred in the first year of ownership, and it's generally treated as an elective or preventive procedure by pet insurers rather than something an accident-and-illness policy reimburses — worth knowing if you're weighing whether pet insurance is worth it as part of your first-year budget, since it typically won't offset this particular cost regardless of when you enroll. It's still worth planning for specifically rather than lumping it into a vague "vet costs" line item, alongside the other first-year expenses covered in our guides to what it actually costs to own a dog and what it actually costs to own a cat. And for large, deep-chested dog breeds at elevated risk of gastric bloat, some owners discuss a preventive gastropexy with their vet at the same time as spay or neuter surgery, since it's already an anesthesia event — our German Shepherd breed guide covers that specific tradeoff in more detail as one example.
