About Insulin Calculator

Meet the Founder

“I built Insulin Calculator on one rule: never ask anyone to trust a number they can't trace. Every formula here is published, cited, and shown alongside your own figures — so you can check the math, understand it, and take it to your care team with confidence.”

Our Mission

Insulin Calculator exists to make the math behind diabetes care clear and freely accessible — to patients, caregivers, students, and anyone learning how insulin dosing actually works. We believe people managing diabetes deserve accurate, jargon-free educational resources without paywalls, logins, or hidden assumptions.

Insulin dosing is one of the most consequential things a person does for their own health, and misunderstanding the formulas behind it can be dangerous. Our goal is to close the gap between clinical knowledge and everyday understanding — not to replace your provider, but to help you have better, more informed conversations with them.

How We Earn Your Trust

Every formula is sourced

We don't invent dosing math. Each calculator uses a formula that is:

• Published in peer-reviewed literature or major clinical guidelines (ADA, AACE, NIDDK, CDC)
• Cited on the page, with the specific source named and linked where possible
• Shown transparently — the equation and your exact inputs appear with every result
• Framed as an estimate, never as a prescription or a definitive dose

Content is reviewed and dated

Clinical content is written against primary sources (listed on each page) and checked against the current ADA Standards of Care in Diabetes. Every substantive page carries a “Last reviewed” date, and we revisit pages when guidelines change.

What we will never do

• Fabricate credentials, reviewers, testimonials, or trust badges
• Claim our founder or team are doctors when they are not
• Present a calculator's output as a prescription or clinical recommendation
• Use formulas that lack published clinical support
• Let advertising influence clinical content
• Collect or transmit your health data — every calculation runs locally in your browser

Our Honesty About Expertise

Because this is a health-related site, we want to be completely clear about what we are — and what we are not. Insulin Calculator is an educational publisher, not a medical practice. Our founder and contributors are not your healthcare providers, and using this site does not create any clinician–patient relationship.

What we bring is editorial rigor: faithful reproduction of well-established, published formulas; transparent calculations you can verify; and clear, repeated signposting to professional care. The clinical authority behind the numbers belongs to the sources we cite — the ADA, AACE, NIDDK, and the peer-reviewed researchers who developed and validated these methods. Where a calculation touches higher-risk situations (children, pregnancy, IV insulin, severe resistance), we say plainly that specialist supervision is essential.

Who This Site Is For

• People with diabetes and their caregivers who want to understand the logic behind a dose
• Nursing, pharmacy, and medical students learning clinical calculation methods
• Diabetes educators and coaches who explain these concepts to others
• Anyone curious about the math behind insulin therapy

These tools are not a substitute for a certified diabetes care and education specialist (CDCES), endocrinologist, or primary care physician. If you are newly diagnosed, changing regimens, or managing complications, work directly with your care team.

Accuracy & Limitations

Standard formulas like the 500 Rule (insulin-to-carb ratio) and the 1800 Rule (sensitivity factor) are widely used as starting points. They are not precise for every individual, because real insulin requirements shift with:

• Physical activity level and exercise timing
• Diet beyond carbohydrate counting (fat, protein, glycemic index)
• Stress, illness, and hormonal changes
• Kidney and liver function
• Other medications
• The specific insulin and injection site

We acknowledge these limits on every tool page and ask you to treat all outputs as educational estimates to verify with your provider.

Who Operates This Site & How to Reach Us

We believe a trustworthy health resource should be accountable and easy to reach. Insulin Calculator is independently operated, and you can contact a real person with corrections, questions, or feedback — we especially welcome corrections from clinicians and educators.
