At Everyday Calculators, our mission is simple: to provide fast, accurate, and reliable tools that help you make better decisions in your daily life. Whether you are managing a home improvement project, tracking your finances, or caring for your pets, we believe that having the right data at your fingertips should be easy, accessible, and stress-free.
Everyday Calculators is managed by Robert Henigan. With a professional background in manufacturing quality assurance and herbal supplement production, I bring a technical, precision-focused mindset to every tool I build. My goal is to combine the rigor of industrial standards with the simplicity of user-friendly design.
We have a special focus on pet health. As pet owners ourselves, we know the panic that sets in when you aren’t sure if a certain food is toxic to your dog or cat.
Our pet safety resources are developed in collaboration with , Dr Monica Watts, BVSc a practicing veterinarian with over 25 years of clinical experience. Her expertise ensures that our toxicity calculators and safety guidelines align with current veterinary medicine standards.
Note: While our calculators are built on professional veterinary standards, they are intended for informational purposes and should not replace the advice of your local veterinarian in an emergency.
Beyond pet health, this site was born from a personal need. As a fitness enthusiast, I wanted a way to track my workouts and energy expenditure effectively while on the move. I couldn't find a suite of tools that were fast, clean, and mobile-friendly enough for the gym floor. So, I built them myself.
Today, this site has grown into a comprehensive library of over 20 calculators covering construction, finance, health, and fitness—all optimized to work perfectly on your mobile device.
Every calculator on this site is derived from industry-standard formulas, whether it is the MET system for our fitness tools or standard veterinary dosage guidelines for our pet health resources.
