About PetCalcHub
Free, science-backed pet calculators with AI-powered health insights.
Our Mission
PetCalcHub was built with a simple belief: every pet parent deserves access to reliable, science-backed tools to make informed decisions about their pet's health — without paywalls, signups, or data collection.
We combine veterinary-standard formulas from trusted sources — including AAHA, AAFCO, NRC, and Merck Veterinary Manual — with AI-powered insights that personalize each result for your specific pet. The result is a tool that doesn't just give you a number; it helps you understand what that number means and what to do next.
Why We're Different
Science First
Every formula is documented and sourced from peer-reviewed veterinary research. No guesswork, no "old wives' tales."
AI-Enhanced
Our AI engine generates personalized care tips based on your pet's specific results — breed, age, weight, and life stage.
Privacy First
All calculations happen in your browser. We never collect, store, or share your pet's information. No accounts, no tracking.
Always Free
We believe essential pet health tools should be accessible to everyone. We're funded by advertising, not your data.
