Zakat Calculator
Free Zakat calculator. Calculate your Zakat obligation on cash, gold, silver, stocks, business assets, rental income, and cryptocurrency.
How This Calculator Works
Calculation methodology and assumptions
Zakat is one of the Five Pillars of Islam — an obligatory charitable contribution of 2.5% of qualifying wealth held for one lunar year. Qualifying assets include cash, gold, silver, investments, business inventory, and receivables. Debts owed by you are subtracted. Zakat is due only if total net assets exceed the Nisab threshold (equivalent to 85 grams of gold or 595 grams of silver — approximately $5,500 using gold standard).
How to Use This Islamic Finance Calculator
- 1
Enter the asset or purchase price
For Murabaha mortgages, enter the property price. For Zakat calculators, enter total qualifying wealth (gold, silver, cash, investments, business inventory).
- 2
Set the profit rate or Nisab threshold
Murabaha uses a disclosed "profit rate" instead of interest. Zakat uses the Nisab threshold (85g gold or 595g silver equivalent) to determine obligation.
- 3
Review the Sharia-compliant structure
The methodology section explains how each calculation conforms to Islamic finance principles — no riba (interest), no gharar (excessive uncertainty), and no investment in haram industries.
- 4
Analyze the total cost
Compare the total cost of Islamic financing vs. conventional. While structured differently (cost-plus vs. interest), the total amounts are often comparable. The critical difference is the structure's compliance with Sharia law.
Example Calculation
Let's walk through a Murabaha home purchase calculation.
You want to buy a $400,000 home. An Islamic bank purchases the property and sells it to you at a disclosed markup. With a 20% down payment ($80,000), the bank finances $320,000. The bank applies a cost-plus markup of 3.5% annually over 30 years. Under Murabaha, this is structured as a sale agreement, not a loan — the total price is fixed upfront.
Result: Total purchase price: $320,000 × cost-plus factor = approximately $517,000. Monthly installment: ~$1,436. The key difference from conventional mortgages: the total price is fixed from day one with no compounding interest, and the structure avoids riba. Actual costs depend on the financial institution's markup and terms. Islamic banks like Guidance Financial and UIF offer Sharia-compliant products in the US.
What Affects Your Results
Profit Rate vs Interest Rate
Islamic finance uses a disclosed profit margin instead of interest. While mathematically similar, the legal and spiritual structure differs — the bank owns the asset and sells it at a markup, rather than lending money at interest.
Nisab Threshold
The Zakat threshold is tied to the current market value of 85 grams of gold (~$7,500–$8,500) or 595 grams of silver (~$450–$550). Most scholars recommend using the silver-based Nisab for a more conservative calculation.
Qualifying Wealth
Zakat applies to savings, investments, gold/silver, business inventory, and receivables — but not personal-use items (home, car, furniture) or business assets (machinery, equipment).
Lunar vs Solar Year
Zakat is calculated on the Hijri (lunar) calendar, which is ~11 days shorter than the Gregorian year. This means your Zakat date advances ~11 days each year.
Tips for Zakat Residents
- Zakat is obligatory at 2.5% of qualifying wealth above the Nisab threshold, calculated on the lunar calendar year. Use the gold-based Nisab for a higher threshold or silver-based for a lower one (more conservative).
- For Murabaha mortgages, compare total cost of ownership (not just the "rate") across Islamic banks. The effective cost can vary significantly between institutions.
- Diminishing Musharaka (partnership) is an alternative home financing structure where you gradually buy out the bank's share — often preferred by scholars over Murabaha for its shared risk.
- Business inventory, trade goods, and agricultural produce each have specific Zakat rates. Cash and investments are uniformly 2.5%, but livestock, crops, and minerals have different rules.
- Several US states have modified their lending regulations to accommodate Islamic finance structures. Check with local Islamic financial institutions for state-specific compliance details.

Our editorial standardsFrequently Asked Questions
What is Nisab?
Nisab is the minimum amount of wealth a Muslim must possess for one lunar year before Zakat becomes obligatory. It is equivalent to 85 grams of gold (~$5,500 USD) or 595 grams of silver (~$450 USD). Most scholars recommend using the gold standard.
Is Zakat due on cryptocurrency?
Most contemporary scholars agree that cryptocurrency is subject to Zakat since it holds monetary value and can be traded. Zakat is calculated at 2.5% of the current market value on your Zakat anniversary date.
Is Zakat due on my primary home?
No, Zakat is not due on your primary residence, personal vehicle, furniture, or personal clothing. These are considered necessities. However, Zakat IS due on rental income saved and investment properties meant for sale.
When do I pay Zakat?
Zakat is typically paid once per lunar year (Hijri year) on the anniversary of when your wealth first exceeded Nisab. Many Muslims choose to pay during Ramadan for increased spiritual reward.
