Veterinary Clinical Calculators
Evidence-informed calculators and reference tools developed to support nutrition, weight assessment, and client communication in veterinary practice.
Core calculators
These calculators are currently available and used most frequently in clinical obesity and nutrition workflows.
Daily Energy Needs (DER / MER)
Estimate daily caloric requirements using standard veterinary energy equations and practical activity adjustments.
STEP Weight Loss Calculator
Build a structured weight-loss plan with target calories and stepwise guidance to support client adherence.
Calculators are provided as clinical support tools and educational references. Outputs are estimates and should be interpreted in the context of individual patient assessment and professional judgment. APOP does not provide diagnostic or treatment directives through these tools.
