Assalamualykum,
I Need a comprehensive guidance of zakat calculations. Is this methodology (https://youtu.be/JdQ2VjnllSU) correct. If no, please let me know the correct procedures.

الجواب وبالله التوفيق
You should take out 40th portion of the amount you own for the payment of Zakat. It would be beneficial to review Bahishti Zewar for further details.
واللہ اعلم بالصواب
