About pancalc

What we do

pancalc is a free online calculator platform covering health, finance, math, science, and everyday topics. Every tool runs in your browser — no account required.

Our mission

We aim to make reliable calculations accessible to everyone. Each calculator pairs clear explanations with transparent formulas so you can understand the result, not just the number.

Who runs pancalc

pancalc is operated by a small independent team focused on building useful, well-documented calculator tools. We are not affiliated with any government agency, medical institution, or financial firm.

How the site is funded

pancalc is free to use. We may show third-party advertisements (such as Google AdSense) to support hosting and development. Advertising practices are described in our Privacy Policy.

Editorial standards

Each calculator page is written for that specific tool — not mass-produced from a single template. Articles include worked examples, formula notes, practical tips, and limitations that name the actual inputs and outputs on the page.

We avoid generic FAQ boilerplate and duplicated walkthrough text across unrelated calculators. When you read a pancalc article, the scenarios and field names should match the live tool above the prose.

How we verify math

Calculator logic lives in a typed engine registry with automated golden tests: reference inputs and expected outputs that must pass on every build. Worked examples in articles are checked against those same reference values.

If you believe a formula or example is wrong, email us with the calculator URL, the inputs you used, and the result you expected. We treat corrections seriously and update both the engine and the article together.

Updates and corrections

We add calculators and expand articles over time. Significant formula or copy fixes ship as soon as they are verified — you do not need an account to receive updated pages; refresh the browser to load the latest static build.
