How much does a Muslim have to pay for chatity?

In Islam, the mandatory form of charity is called Zakat, which is typically 2.5% of a Muslim's accumulated wealth over the course of a lunar year. This includes savings, investments, and certain assets but excludes personal items like one's home or clothing. Additionally, Muslims are encouraged to give voluntary charity, known as Sadaqah, which can be any amount and is given at any time to help those in need.
