CalculatorPro is run by a small team led by Furqan Haider. We started this site because we wanted a place with fast, uncluttered calculators — tools that give you a straight answer without paragraphs of filler before you even reach the input box. We launched in 2026 and are still actively adding to the collection.
Every calculator on this site is coded by our own team — we don’t license or embed third-party calculator widgets. For health and fitness tools, we base the underlying math on established public references: CDC growth charts for the kids’ BMI tool, WHO’s adult BMI classification, ACOG and NICHD guidance for pregnancy dating, and the Devine, Robinson, Miller, and Hamwi formulas for ideal body weight. Where we can, we link to the specific source we used directly from the calculator’s page.
Some questions — like “ideal body weight” — don’t have one universally agreed formula. In cases like this, our Ideal Weight Calculator shows results from multiple recognized formulas side by side instead of picking one and hiding the disagreement. These tools are built for everyday, informational use and aren’t a substitute for advice from a doctor or other qualified professional.
We’re a small team, not a large publisher — which means when something’s wrong, we can usually fix it fast. If you spot an error in a calculator’s result, a mistake in an article, or anything else that looks off, email us using the contact details below and we’ll look into it.
All health and medical content on this site is reviewed by Dr. Imtiaz A Chaudhry, MD, PhD, FACS. Dr. Chaudhry has full access to our site and reviews our health calculators, articles, and their underlying formulas for medical accuracy. You can view his professional credentials on LinkedIn.
