Free Islamic calculators, built to be accurate and easy to use.
DeenHisab is a free collection of Islamic calculators: zakat, Islamic inheritance (Fara'id), zakat on stocks and on money lent out, Ushar, Fitrana, prayer times, Qibla direction, Hijri date conversion, Ramadan tools, and an Islamic baby name generator. Everything is free to use — no accounts, no paywalls, no watermarks.
These calculations matter — how much zakat you owe, how an estate is shared, when to break your fast — but the rules are detailed and easy to get wrong. DeenHisab exists to make them simple and reliable: type in your numbers, get a clear answer, and see the reasoning behind it.
Where scholars differ, we show the difference instead of hiding it. Our calculators show both Hanafi and Jumhur (Shafi'i, Maliki, Hanbali) views where they differ, and our inheritance engine was tested against a published Fara'id reference implementation across 2,000+ heir combinations. Sources are cited on each calculator page.
That said, DeenHisab is an educational tool, not a fatwa. For a final ruling on your own situation, please consult a qualified scholar.
Every calculation runs in your browser. Nothing you enter is sent to a server. See our Privacy Policy for details.
DeenHisab is made by Muhammad Iftkhar in Pakistan, who also runs the WaliInsights YouTube channel, sharing Islamic stories, reminders and practical guidance in Urdu.
