Understanding Islamic Investing & Zakat
What is Zakat on Investments?
Zakat is one of the five pillars of Islam, an obligatory form of charity calculated at 2.5% of eligible wealth held for one lunar year (hawl). This includes savings, gold, silver, stocks, mutual funds, and investment portfolios that exceed the nisab threshold (equivalent to 85g of gold or 595g of silver).
Halal Investment Principles
Shariah-compliant investing avoids riba (interest),gharar (excessive uncertainty), and haram industries including alcohol, gambling, pork, and conventional financial services. Halal options include Islamic mutual funds, sukuk (Islamic bonds), and Shariah-screened equities.
How This Calculator Works
Enter your initial investment and monthly contributions to project growth using compound returns. Enable the Zakat toggle to see how annual 2.5% payments affect your portfolio over time. The inflation adjustment shows your money's real purchasing power in today's terms.
Compound Growth & Zakat Impact
While compound returns grow your wealth exponentially, paying Zakat annually purifies your earnings and fulfills your religious obligation. This calculator shows both nominal and post-Zakat growth trajectories, helping you plan realistically while staying Shariah-compliant.
Frequently Asked Questions
How is Zakat calculated on investment portfolios?▼
Zakat on investments is calculated at 2.5% of the total market value of your zakatable assets held for one lunar year. This includes the principal amount plus any gains. If you hold stocks, you pay Zakat on the current market value, not the original purchase price. The nisab threshold must be exceeded for Zakat to be obligatory.
Is compound interest halal in Islam?▼
Traditional compound interest (riba) from conventional savings accounts or bonds is considered haram in Islam. However, compound growth from Shariah-compliant investments—such as profit-sharing arrangements, equity investments in halal companies, or sukuk—is permissible. This calculator models growth from halal investment returns, not interest-based products.
Should I calculate Zakat on the full portfolio or just profits?▼
Zakat is calculated on your entire investment portfolio value (principal + profits), not just the gains. According to most Islamic scholars, if you own stocks or mutual funds intended for growth (not active trading), you pay 2.5% Zakat on the current market value of your holdings. Always consult a qualified Islamic scholar for specific rulings.
What is the nisab threshold for Zakat?▼
Nisab is the minimum wealth threshold that makes Zakat obligatory. It equals the value of 85 grams of gold or 595 grams of silver. Most scholars recommend using the silver nisab as it benefits more recipients. As of 2024, this is approximately $400-600 USD depending on current silver prices. If your total zakatable assets exceed nisab for one lunar year, Zakat becomes obligatory.
How does inflation affect my halal investments?▼
Inflation erodes purchasing power over time. While your investment might show nominal growth of 8% annually, if inflation is 3%, your real return is only about 5%. This calculator's "Real Value" feature shows what your future wealth will actually buy in today's terms, helping you set realistic financial goals for your Muslim family's future.
