Zakat is one of the five pillars of Islam --- an annual obligation for eligible Muslims to give a portion of their wealth to those in need. In the U.S., calculating zakat accurately can feel confusing, especially when you're dealing with multiple income sources, investments, and varying gold/silver values.
This guide explains the step-by-step process for calculating zakat in 2025 based on U.S. nisab values and financial conditions, and lists a few free online zakat calculators you can use right now.
What Is Zakat?
Zakat is a mandatory form of charity required for Muslims who meet the nisab threshold --- the minimum amount of wealth one must have before zakat becomes due. It is generally 2.5% of qualifying wealth held for a full lunar year (hawl).
Purpose of zakat:
- Purifies wealth
- Supports the poor and needy
- Redistributes resources to maintain social balance
Step 1 -- Determine Your Nisab
The nisab can be calculated using either gold or silver values. In 2025, U.S. Muslims typically use gold prices to set a higher, more realistic threshold for local economic conditions.
- Gold: 87.48g (3 oz) = ~$6,300 USD
- Silver: 612.36g (21.6 oz) = ~$550 USD
Prices are estimates based on current spot rates in early 2025. Always check the latest prices before calculating.
If your total zakatable assets meet or exceed the nisab value, you must pay zakat.
Step 2 -- Identify Zakatable Assets
Include the following:
- Cash on hand and in bank accounts
- Gold and silver (jewelry or bullion)
- Stocks and investments (at market value)
- Business inventory (at wholesale value)
- Rental income savings
Exclude:
- Primary residence
- Personal items (car, furniture, clothes)
- Immediate living expenses
Step 3 -- Deduct Liabilities
Subtract debts that are due for payment within the lunar year:
- Credit card balances
- Outstanding bills
- Business payables
Step 4 -- Apply the 2.5% Rate
Once you have your net zakatable assets: Zakat = Net Assets × 2.5%
Example: Total zakatable assets: $50,000, Liabilities: $5,000, Net assets: $45,000, Zakat due: $45,000 × 2.5% = $1,125
