How Zakat is Calculated
Step 1: Nisab Check
Total wealth must exceed the nisab threshold (85g gold or 595g silver) before zakat is due.
Step 2: Hawl Tracking
Assets must have been owned for a full lunar year (354 days). Assets held shorter are excluded.
Step 3: 2.5% Rate
Apply 2.5% on the total zakatable value of all eligible assets. This is the standard rate.
