Summarize this article:

Start calculating your assets, or what you own. This is the first step is figuring out how much zakat you'll pay. You exclude the assets you use for everyday life. For example, your primary residence, car, clothes and business equipment are not used in your zakat asset calculations. It's based on what's left after you take care of you and your family's living expenses.   Some examples of zakat-eligible assets include stocks, savings, investment properties, cash, business income or precious metals such as gold. Determine how much your zakat-eligible assets are worth for the year. Debt from credit cards, college or other loans subtracts from your personal net worth. These outstanding debts are deducted from your total zakat-eligible assets.  If you obtained a personal loan of any type (car, home, cash), then look at how much you pay per month to your creditors, not the entire outstanding debt. Add up how much you owe each month to your creditors. Multiple this amount by 12 to calculate your annual liability amount. Subtract your liabilities from your zakat-eligible assets. For example, your assets for the year total $6,000 and your liabilities total $2,000. Your zakat net worth or zakat pool of money is $4,000 ($6,000 - $2,000 = $4,000).

Summary:
Identify your assets. Identify your liabilities. Determine your zakat net worth.
