Calculating zakaat

Q: For Zakaat calculation; silver has very less value compared to gold. So which one should be considered to calculate Zakaat? 52g of silver is worth $380 and Gold which worth $4000.

Q: My father saves enough money and my mother has jewellery. I know the nisaab for savings, gold and silver. As per the criteria, Zakat is wajib on my parents. Till now, in their entire life they didn't pay zakat. They did toubah (repented) for not paying it. Now how do they pay zakah for all the previous years because they don't know when they became sahib-e-nisaab.

Also determining the savings of my father for all the previous years is quit complicated. How much should they start giving from this year?

Q: Should one pay zakaat on the money given as a deposit for purchasing a house?

Q: I want to know how much zakat I have to give. I have started earning on my own. How much amount after completion of one year I have to give and to whom?

Also, if I use money for construction or buying any property, is Zakat mandatory for that purchased land or home?

Q: I'd like to know how to calculate zakaat. I am 25 years old and have never paid it as I don't know how to calculate it. I do tutoring for 2 children, I have some shares, I have some money in my bank account and I have money in a money box but I don't know how much money I have in that money box. I also have some gold jewellery of which I wear some of it but not all and I don't know the value of it.

Is it true that you have to also pay zakat on clothing that you have not used in over a year? Please assist. 

Q:

1. Is zakaat payable on provident fund?

2. If payable is it only on employees portion or employers portion?

3. If payable, is the value based on market value less estimated tax payable? Note tax is only paid when money is withdrawn from the fund.

Q: If one has not payed zakaat for previous years and now wishes to do so, will they calculate when they became saahib nisab based on todays nisab or nisab of that particular day?

Q:

1. I want to ask about the obligatory charity (zakat). There are some things which I want to know about rules of zakat. First of all I want to know rules about paying zakat on inherited wealth. My father died and the money in his account was given to me after 7 months. My father died in 8th month of Islamic calender. He used to give zakat in Ramadan. Maybe the time was complete for giving zakat ( i do not know for sure) but he died before that. So the question is that was I supposed to pay on his behalf or not. If not then when should i pay zakat. Should I calculate day from that one on which he died or the one which i received money from bank 7 months later.

2. Also the money in bank is of two kinds. One is that which me and my father saved. The other is not ours. It is security deposit of the shop keeper and the person who lives at rent in our house. Some of the shop keepers have been here for 20 or 25 years. So am I supposed to pay zakat including the deposit or just the one we saved.

Q: On which amount zakat should be paid "on market value of rental property or on the rent"?

Q: I earn a salary upto 40,000 rupees per month. Sometimes I save the complete salary and sometimes I give part of my salary (20,000 to 30,000) to my family for their shop. Currently I have 60,000 rupees in the bank and I have been working since last year, is zakaat waajid upon me? If yes, how do I calculate the zakaat?
