How is the Nisab (minimum threshold) for Zakat calculated?

The Nisab is traditionally based on either the value of roughly 87.48 grams of gold or roughly 612.36 grams of silver, and scholars differ on which standard to apply and how to value mixed assets in cash-based economies today. Because Nisab values change with market gold/silver prices and the calculation can involve combining different asset types, it's best to calculate your specific Nisab and Zakat amount with the help of a knowledgeable scholar or a trusted Zakat calculator reviewed by one, rather than estimating.
