Calculate the portion of your dividend income to give away so your investment returns stay Shariah-compliant.

When you receive dividends from a company that has some non-compliant income, you need to purify (give away as charity) a portion of your dividend equal to the company's purification ratio. This ratio represents the percentage of the company's income that comes from non-compliant sources.
Screen your stock in the Shariah Screener to get the purification ratio automatically.
Multiply your dividend by the purification ratio to find the amount to give in charity.
The remainder is your halal dividend income, free from non-compliant earnings.
Net Halal Income
After purifying Rs 5,000, your halal income is Rs 95,000.
