See both the gold-based and silver-based Nisab in your currency, side by side, so you know exactly what threshold your wealth is measured against.
Default values above are only placeholders — enter today's real local gold and silver prices per gram for an accurate result.
Most contemporary scholars recommend using the silver Nisab as the default threshold since it is lower, meaning more people qualify to pay Zakat (and more wealth reaches those in need) — this is considered the safer, more cautious position. Some prefer the gold Nisab for cash-equivalent wealth; if unsure, ask a qualified local scholar which your community/madhhab uses.
