Fitra is a required charity given at the end of Ramadan, and before Eid-ul-Fitr prayers, to show gratitude to Allah for allowing us to observe the obligatory fasts in Ramadan with compassion and steadfastness. The head of household pays it on behalf of every family member, and it is compulsory for every individual who has sufficient food for themselves and their family.
The estimated cost is $10 per person in each household.

When a person is unable to fast due to a valid reason such as travel, illness, old age, harmful levels of thirst or hunger, or oppression, Allah allows them to make up the missed fast(s), if possible, or offer fidya in which a needy person is fed for each missed fast.
The estimated fidya is $10 for each missed fast, or $300 for all of Ramadan.
If the donor is from a low-income family and cannot afford the payment, they should prioritize their family’s needs before giving a fidya donation.

Kaffarah may also be given to compensate for unfulfilled oaths or promises. In such situations, 10 underprivileged people should be fed for each occurrence.
The estimated kaffarah is $100 per unfulfilled oath.
If the donor is from a low-income family and cannot afford the payment, it is recommended they fast for three days and make sure to fulfill their oath and stay true to their word going forward.
