Sirran: Zakat Calculator

Sirran helps you work out your zakat obligation with precision and care. Every calculation uses exact rational arithmetic — no rounding errors, no floating-point shortcuts.

Enter your assets across standard categories:
• Cash and bank balances
• Gold holdings
• Silver holdings
• Business inventory (valued at market or cost price)
• Receivables (good and doubtful)
• Liabilities due this year
• Agricultural produce (irrigated and rain-fed)

Choose your nisab standard — gold (85 g) or silver (595 g) — and see results under both. Scholars differ on which standard to use, and Sirran shows both so you can follow the opinion you trust.

Every calculation line shows its working and scholarly source reference. You can expand the full breakdown to see exactly how each figure was derived.

Community distribution:
When you know someone who qualifies, Sirran lets a small group of trusted people confirm it without ever publishing who received. The people who confirm can never afterwards tell which help was theirs — the system is built so that connection simply does not exist.

Recipients collect an envelope code or mobile transfer, and the giver never learns who received their zakat. Requests are gathered and shuffled together so that timing cannot identify anyone.

The server cannot connect a confirmation to a payment. This is not a policy choice — the arithmetic makes it structurally impossible.

Key features:
• Exact arithmetic using rational numbers — never rounds during calculation
• Both gold and silver nisab amounts compared side by side
• Inline method pickers for stock valuation and doubtful receivables
• Community confirming — the people who confirm can never learn which payment was yours
• Requests are gathered and shuffled so timing cannot identify anyone
• Save calculations locally for future reference
• All calculations run on-device — community features need connectivity

Sirran stores calculation data locally on your device. Community features use Firebase for authentication and coordination. Help requests go to a server that checks the mathematics without receiving any identity information.

The calculation follows standard fiqh methodology. Different scholarly positions may give different results — Sirran presents the method you select without concluding any obligation.
