Built to provide Better care under pressure
We built this because we needed it ourselves.
A clinical calculator suite built by veterinary professionals for veterinary professionals. We handle the maths that slows you down — so you can focus on the patient.
The problem we solved
Every vet nurse and clinician knows the drill. A critical patient arrives, you need a fentanyl CRI, and you’re reaching for a textbook, a calculator app that wasn’t designed for veterinary use, or a crumpled piece of paper with a formula you wrote during training.
We built VetCalculate to replace all of that. One tool that covers CRI dosing, sodium correction, potassium supplementation, phosphorus infusions, enteral and parenteral nutrition planning, solution dilutions, and unit conversions.
How we’re different
VetCalculate is instant and build for veterinary medicine. You get calculations as you enter values. You can modify the drug product concentrations or use a searchable database of diet products, and PN components rather than being locked to specific brands. Personalize the default configurations to your patient, your stock, your protocols.
Every algorithm is cross-checked against multiple textbook authorities and developed in collaboration with ECC and anesthesia nurses and diplomates. We don’t just provide a number — we provide a validated clinical trajectory.
And we chose one-time pricing ($49) in a market saturated with SaaS subscriptions. Pay once, yours forever.

To Get Started
What we believe
01
Clinical accuracy first
Every algorithm is cross-checked against multiple textbook authorities. We don’t just provide a number — we provide a validated clinical trajectory.
02
Product agnostic
Use the provided defaults or update with your own drug concentrations. Access a searchable database of dietary products, and PN components. No brand lock-in. Your stock, your protocols.
03
Safety is non-negotiable
Max rate warnings, osmolarity validation, correction rate limits, line safety checks. Every calculation runs through validation before showing a result.
04
Fair pricing
Core calculators free forever. Pro is a one-time $49 — no subscriptions, no recurring charges, no annual renewal.
Built for the vetside
Designed for the person at the bedside making calculations under time pressure.
Vet Nurses
Daily calculator use — CRI setups, potassium supplementation, tube feeding, solution dilutions.
ECC & ICU Veterinarians
Specialist modules — parenteral nutrition formulation, sodium correction, phosphorus infusions.
Veterinary Students
Learning tool for understanding clinical calculations and building confidence before practice.
VetCalculate is part of the Spawtlight suite. We also built CPR Protocol Guide — a RECOVER 2.0 algorithm tool for veterinary cardiac arrest management and Vetside — an evidence-based clinical assistant.
