Purification Calculator
Even Shariah-compliant funds can earn a small share of income from non-permissible sources (under the 5% screening ceiling). Purification means donating that share of your dividends to charity. Pick your fund below — we pull its latest published purification factor automatically. Then enter your dividends and the calculator does the rest.
Donate this amount to charity. Keep a record with your tax files.
How it works
One line of arithmetic per holding: dividends received × purification factor = amount to donate. Funds that publish purification data (like SP Funds) release a new factor each quarter; we track the latest one so you don't have to hunt it down. Add up every holding and you have your annual purification amount.
Where the factors come from
- SP Funds (SPUS, SPTE, SPWO, SPRE) — looked up automatically from SP Funds' published quarterly purification factors (AAOIFI methodology, via ShariaPortfolio). SPSK needs no purification — sukuk are Shariah-compliant by definition.
- WSHR — Wealthsimple publishes dividend purification figures quarterly on their website (per their halal investing help article). Grab the latest figure and enter it manually below.
- HLAL and individual stocks — no published factor we've been able to verify. Check your screening tool (Zoya shows a purification ratio per stock) or enter the figure manually.
- Your brokerage statements — total dividends received per holding for the year (T5 slips in Canada reconcile the numbers at tax time).
When to do this
Once a year, after the calendar year ends and your dividend totals are final — many investors do it alongside their zakat calculation. Our zakat calculator for Canadian investors handles TFSA, RRSP, and FHSA on that side of the annual cleanup (we also compared five third-party zakat calculators).
FAQ
What exactly is purification?
Purification is the practice of donating the non-permissible share of your investment income to charity. Shariah-compliant companies may still earn small amounts of interest income (under the 5% screening threshold), so screening methodologies pair compliance with purification to keep the portfolio clean.
How current are the auto-filled factors?
They're the latest quarter published by the fund — currently Q2 2026, published by SP Funds in September 2026. Funds typically publish new factors about 2.5 months after quarter-end. We update this page as new quarters are released.
Do I purify capital gains too?
Published methodologies differ. The widely practiced retail approach purifies dividends; some scholars extend purification to capital gains realized on sale. This calculator covers the dividend case — for gains, ask a qualified scholar which methodology to follow.
Where should the money go?
To charity — any charitable cause, given without expectation of return. If you want the Canadian charitable donation tax credit, the recipient must be a registered charity and you need the official receipt.
