About HalalCalculator

Useful Islamic tools, built around clarity.

A practical companion

HalalCalculator brings together free calculators and planning tools for Muslim everyday life. Our focus is understandable arithmetic, clearly explained methods and a calm experience on both phones and computers.

How we approach trust

We distinguish calculated results from religious decisions. We link to reference material and explain assumptions. We do not claim scholar certification, endorsement or review that has not taken place.

A focused first collection

This collection includes 17 tools and twelve original guides. The inheritance tool covers clearly defined primary-heir cases; extended family cases, investment screening and binding religious verdicts require specialist review. We favour useful tools whose inputs and limitations can be made clear.
