Fasts missed because of menstruation or postnatal bleeding ARE made up. This is the opposite of prayer, where those days are not made up at all, and people get the two backwards constantly. All four schools agree on it. Enter those days below and they will be counted as qada.
Kaffarah is not a payment. The classical expiation is, in order: freeing a slave, and failing that fasting sixty consecutive days, and failing that feeding sixty poor people. The order is binding — money is the third option, reached only by someone genuinely unable to fast, not a fee to skip the fasting. This tool will not reduce it to a single figure.
No exchange rates and no food prices are fetched. None is configured for this site, and an invented rate would silently produce a wrong obligation — which is worse than asking you to look it up. You enter the local cost of one average meal and pick the currency yourself; everything else is multiplication.
If your case is unusual — a chronic condition whose outlook is uncertain, fasts owed from many years ago, or a fast broken in circumstances you are unsure how to describe — ask a qualified scholar. Nothing on this page is a ruling.
