It is necessary to calculate Zakat correctly to ensure one is fulfilling this command of Allah properly. It is strongly encouraged that one reviews his accounts and finances for the previous years and the amount of Zakat disbursed. This will clarify if there is a deficit in payment. One can make amends thereafter. Please be aware that zakat is the right of the eligible recipient (and not the “Donor’s”). In other words, it is as if he/she has given you an asset to safeguard on their behalf and which you need to return at the prescribed time. Therefore, you should try your best to calculate your zakat liability as accurately as possible.
And Allah knows best!
