What is the amount of zakat that must be paid on a sum of 2,159,0 Algerian Dinars that has been available since September 2018, knowing that the monthly work allowance is 41,400 Algerian Dinars?

Whoever possesses wealth reaching the nisab (the equivalent of 85 grams of gold or 595 grams of silver) and it remains with them for one lunar year, zakat becomes obligatory on it at a rate of one-quarter of one-tenth (2.5%). Zakat for past years must be paid from the day the nisab was completed, taking into account the change in wealth for each year separately. It is not permissible to delay it except for an overwhelming excuse.
