In the context of companies and businesses, it is the excess of zakatable assets over short-term liabilities. Zakatable assets are those which meet the conditions of obligatory zakah, that is (1) Unencumbered and full ownership. (2) actual and assumed growth. (3) the passage of one lunar year except for agricultural and horticultural wealth (where zakah falls due at the time of harvesting and picking). (4) attainment of nisab (i.e., the minimum obligatory amount). (5) free of debt which is due at the time.

The short-term liabilities represent all debts and obligations that fall due within a year provided that they are related to the business activities and interest-free (shari’a compliant).

The amount zakah due is, thus, the zakah base, at or over nisab, multiplied by zakah rate:

Amount of zakah payable= zakah base × zakah rate

The rate of zakah varies according to the types of wealth/ assets and activity. Typically it ranges from 2.5% to 20% for lunar years.
