Missed Fast (Qada) Calculator
Estimate your total missed Ramadan fast (qada) debt and build a weekly or monthly make-up plan with an estimated finish date.
Ramadan is 29 or 30 days each year. Fasts missed due to illness, travel, pregnancy or forgetfulness must be made up as qada.
This calculation is an estimate and is not a religious ruling (fatwa). It is recommended to consult a qualified scholar about your missed fasts.

What is a qada fast, and how is the debt calculated?
A qada fast makes up a Ramadan fast that was missed for a valid reason, and a make up fast calculator turns that obligation into a number you can plan against. The arithmetic is plain: from the days missed since religious maturity, subtract the days you have already made up.
For women, menstruation days count towards this total. Unlike prayer, fasting remains a debt and has to be made up later, and that is the single most confused difference between the two duties. Seven days a year comes to roughly 70 fasting days over a decade.
The tool works two ways: enter the yearly average of days missed, or enter the total directly. Add how many days a week you plan to fast and this fasting debt calculator returns an estimated finish date, so two days a week clears 70 days in about eight months.
The intention and when to make it
The intention for a qada fast is made the night before, unlike a voluntary fast. In the Hanafi and Shafi'i schools, obligatory and make-up fasts require the intention to be settled before dawn, so at the latest during suhoor. A qada fast cannot be started once the day has begun.
Holding the intention in the heart is enough; saying it aloud is sunnah. There is no need to name which year the missed fast belongs to.
Can a qada fast be broken?
Yes, a qada fast that has already begun can be broken. In that case only one day is made up in its place and no expiation (kaffara) applies. Kaffara concerns the deliberate breaking of a Ramadan fast without excuse and means 60 consecutive days of fasting. Knowing the difference prevents taking on a burden that is not owed.
Eating or drinking by mistake does not break the fast; you stop as soon as you notice and carry on.
Forbidden days, and when fidya applies
Five days of the year are closed to fasting: the first day of Eid al-Fitr and the four days of Eid al-Adha. Every other day is open. Winter makes the debt easier to clear simply because the days are short.
Anyone permanently unable to fast because of chronic illness or old age pays fidya instead of making up the days: the cost of feeding one person for a day, for each day missed. A temporary illness with a prospect of recovery does not qualify, and the fast stays a debt.

Frequently Asked Questions About the Missed Fast (Qada) Calculator
The intention can be made up to before dawn. It is enough to intend the night before, before the pre-dawn meal (suhoor), "I intend to keep a make-up fast tomorrow." The intention is essentially of the heart; saying it aloud is recommended but not required.
If a qada fast is broken intentionally, only that day needs to be made up again; the expiation (kaffarah) required for breaking a Ramadan fast (60 days of fasting or feeding 60 people) does not apply. For qada fasts, only re-doing that day is needed.
Determine the number of Ramadans since you started fasting, estimate how many days of make-up fasts you have for each Ramadan, then subtract the days you have already kept. The remaining number of days is your total fasting debt.
Fidya applies to those who permanently lose the ability to fast, such as the elderly or those with a chronic illness with no hope of recovery. Those who are able to make up fasts must fast rather than pay fidya. The exact amount is set locally and updated each year.
