Built for clarity, not just answers
How pancalc works
Every calculator pairs a live tool with a long-form article: formula notes, worked examples, and limitations written for that specific tool — not generic filler copied across pages.
Calculations run in your browser. No account is required, and we document which fields are inputs versus computed outputs so you can reproduce a scenario later.
How we verify calculations
Engine logic lives in a typed registry with automated golden tests — reference inputs and expected outputs checked on every build.
When we expand an article, worked examples must match those golden values. If something drifts, the build fails before the page ships.
