Calculate Zakat on business assets, inventory, trade receivables, and cash — based on current Nisab threshold.
Zakat is 2.5% of net zakatable wealth held for one full lunar year (Hawl) above the Nisab threshold.
The Silver Nisab (612.36g silver) is generally considered more inclusive and is recommended by many scholars for business owners.
Fixed assets (machinery, property, vehicles) used in business are not zakatable. Only liquid and tradeable assets count.
