Most Muslim investors never calculate their Zakat on stocks.

Not because they don't want to — because it's genuinely confusing. Nisab thresholds, purification percentages, CGT allowances. This spreadsheet does all of it for you. Fill in the yellow cells, the rest is automatic.

6 Tabs. Everything You Need.

Each tab is pre-built with formulas — no setup required.

▶ Start Here

Your 5-Step Setup Guide

Opens to a personal onboarding page. Know exactly what to fill in first, in what order, and why — no confusion, no guesswork.

Dashboard

Your Full Financial Picture

Total portfolio value, gain/loss, zakat due, and purification — all auto-calculated the moment you update your holdings.

Holdings Log

Track Every Investment

Enter symbol, quantity, buy price, and current price. Gains go green, losses go red — automatically. Includes a Halal status dropdown with dropdown validation.

Zakat Calculator

Know Your Zakat Exactly

Add your cash, gold/silver, and debts. Portfolio value is pulled in automatically from your Holdings Log. Zakat (2.5%) only calculates if you exceed the nisab — just like it should.

Purification Tracker

Never Miss a Purification

Enter dividends received and the haram revenue percentage per stock. The exact amount to donate to charity is calculated for you — no mental arithmetic needed.

UK Tax Estimator

Maximise Your Tax Allowances

CGT (£3,000 allowance), dividend tax (£500 allowance), ISA (£20k), and SIPP relief — all for 2025/26. See exactly where you stand before the tax year ends.

You're already ahead of most investors.

The fact that you're here — thinking about Zakat on investments, purification, and halal compliance — puts you in a very small group. This spreadsheet makes it easy to act on that intention.
