Pet-calc honestly calculates the true cost of owning a pet: from the initial purchase price to monthly and annual costs, all the way through its entire lifespan. Completely offline, ad-free, and no account required.
THE CALCULATORS
• Dog – size, origin (shelter or breeder), food quality, insurance, grooming, dog tax, training, and care.
• Cat – food, litter, veterinary care, insurance, indoor or outdoor access.
• Rabbits & Guinea Pigs – honest calculations are provided for two or more animals, as keeping them alone is considered animal cruelty. Costs per animal scale, the enclosure remains shared; indoor or outdoor housing changes the initial setup costs.
WHY RANGES INSTEAD OF APPARENT PRECISION
Each result shows a realistic range, in addition to the typical value, based on verified sources (including GOT, ZZF, and the German Animal Welfare Federation). Pet costs can only be honestly stated as a range – not down to the last euro.
Rabbits & Guinea Pigs – honest calculations are provided starting with two animals, as keeping them alone is considered animal cruelty. FEATURES
• Emergency Reserve: The item almost everyone underestimates – a single emergency surgery can quickly cost thousands. If you choose surgical insurance, the calculator automatically reduces the reserve to prevent double billing.
• Donut chart of cost distribution: First year vs. subsequent year in comparison.
• Explanation Mode: Tap and read technical terms, plus A-Z glossary – each entry includes a source.
• German and English, light and dark modes.
• Save and share calculations, and the last entry is remembered.
PRIVACY FIRST
pet-calc deliberately does NOT require internet access. All calculations run 100% on your device – nothing is transmitted, nothing is collected, no advertising, no tracking.
