A Zakat calculator is a digital tool or app designed to help Muslims accurately calculate the amount of Zakat (obligatory almsgiving) they are required to pay. Zakat is one of the Five Pillars of Islam and requires Muslims who meet specific financial criteria to donate a portion of their wealth to those in need. A Zakat calculator simplifies the process by providing a user-friendly interface that helps individuals determine their zakat obligation based on their income, savings, investments, and other assets.
