🕊️ Kaffarah Calculator

Calculate the Kaffarah (expiation) you owe for breaking a sworn oath (Kaffarat al-Yameen) or deliberately breaking a Ramadan fast without a valid excuse (Kaffarat Ifsad al-Sawm), for the common, mainstream simplified cases.

🕌 Expiations & Fidyah
🛡️ Reviewed by: Ihsabha Editorial Team · Method: Qur'an 5:89 for oath expiation and the well-documented hadith of Kaffarat Ifsad al-Sawm (Sahih al-Bukhari & Sahih Muslim), covering the common, mainstream simplified cases only — no sectarian rulings, no data ever leaves your browser · Last updated: August 13, 2026
📖 Note: This tool covers only the common, simplified cases of these two expiations. Freeing a slave (an option mentioned in the original texts for both types) is no longer practically applicable today. If your situation involves a repeated broken fast, a disputed oath, or another edge case, please consult a qualified scholar.

About this tool

Kaffarah (Islamic expiation) is a fixed, prescribed act of worship owed for two very different situations that this calculator handles separately. The first is Kaffarat al-Yameen, the expiation for breaking a deliberate oath sworn by Allah's name, based on Qur'an 5:89: feeding 10 poor persons, clothing 10 poor persons, or freeing a slave, and only if a person is genuinely unable to do any of these, fasting 3 days instead. The second, far heavier, is Kaffarat Ifsad al-Sawm, owed by someone who deliberately breaks a Ramadan fast during daylight hours without any Shari'a excuse — drawn from the well-known hadith of a man who came to the Prophet Muhammad ﷺ confessing this, recorded in Sahih al-Bukhari and Sahih Muslim, where he was instructed to free a slave, then fast 60 consecutive days, then feed 60 poor persons, in that order of ability. This calculator focuses on the mainstream, practically applicable options — fasting and feeding — since freeing a slave no longer applies in practice, and gives a simplified estimate of the people to feed, the days to fast, or the total cost involved.

Kaffarah Explained: Expiation for a Broken Oath and a Deliberately Broken Fast

Kaffarah, often translated as expiation or atonement, is one of the few areas of Islamic worship with a fixed, numerically defined remedy rather than an open-ended act of repentance. Two situations trigger it most often in everyday life, and this Kaffarah calculator is built to handle both: breaking a sworn oath (Kaffarat al-Yameen), and deliberately breaking a Ramadan fast without any valid excuse (Kaffarat Ifsad al-Sawm).

Kaffarat al-Yameen applies whenever someone swears a serious oath by Allah's name — "I swear by Allah I will do X" — and later breaks that promise. Qur'an 5:89 lays out the remedy with unusual clarity: feed 10 poor persons, clothe 10 poor persons, or free a slave, treating all three as equally valid and interchangeable choices. Only when a person genuinely cannot afford or manage any of these three does the ayah permit the lighter alternative of fasting three days instead. This structure matters for a Kaffarat al-Yameen calculator, because it means the fasting option is not simply "whichever is easiest" — it is specifically a fallback for financial hardship.

Kaffarat Ifsad al-Sawm sits in an entirely different category of severity, because it is not about a promise but about intentionally violating one of the five pillars of Islam without excuse. The foundational hadith, recorded by both Imam al-Bukhari and Imam Muslim, describes a man who broke his Ramadan fast during the day and came to the Prophet Muhammad ﷺ in distress. He was told, in strict sequence, to free a slave; if unable, to fast 60 consecutive days; and if still unable, to feed 60 poor persons. Because the sequence was tied to the man's actual financial and physical ability at the time, contemporary scholars differ on whether today's Muslim — for whom freeing a slave is no longer a live option — must still fast 60 days before feeding is permitted, or may choose freely between the two remaining options. This calculator presents both as valid, common paths so a person can see the real-world numbers for either choice.

A critical distinction worth repeating: this severe Kaffarah is owed only for a fast broken deliberately, with no Shari'a excuse — not for illness, travel, menstruation, pregnancy, or any of the recognized exemptions, which require only Qada (making up the day later) with no expiation at all. Confusing the two leads people to either underestimate a serious obligation or needlessly worry over an ordinary, excused missed day. Whichever expiation applies to your situation, converting the ruling into a concrete number of people to feed, days to fast, or total estimated cost makes it far easier to actually fulfill — and, as with any specific or unusual case, a qualified local scholar remains the right person to consult.

Frequently asked questions

What is Kaffarat al-Yameen (expiation for a broken oath)?

Kaffarat al-Yameen is the expiation owed when a Muslim swears an oath by Allah and then breaks it. Per Qur'an 5:89, it is feeding 10 poor persons, clothing 10 poor persons, or freeing a slave — and only if none of these is possible, fasting 3 days instead.

What is the expiation for deliberately breaking a Ramadan fast?

Deliberately breaking a Ramadan fast without any valid Shari'a excuse (Kaffarat Ifsad al-Sawm) requires, per the hadith in Sahih al-Bukhari and Sahih Muslim, freeing a slave, or fasting 60 consecutive days, or feeding 60 poor persons, in addition to making up the day itself (Qada).

Can I choose freely between fasting and feeding the poor for oath expiation?

Yes. For a broken oath, feeding 10 poor persons, clothing 10 poor persons, and freeing a slave are interchangeable options you may choose between freely. Fasting 3 days is only permitted if you are genuinely unable to do any of the other three.

Must the 60 days of fasting for breaking a Ramadan fast be consecutive?

Yes, according to the mainstream position — the 60 days for Kaffarat Ifsad al-Sawm must be fasted consecutively without a break. If the streak is interrupted without a valid excuse, most scholars hold that the 60 days must restart from the beginning.

Does this Kaffarah apply if I broke my fast for a valid reason like illness or travel?

No. This severe expiation applies only to intentionally breaking the fast without any Shari'a excuse. Breaking a fast for illness, travel, menstruation, or similar valid reasons only requires Qada (making up the day later), with no Kaffarah owed.
