To atone for a missed/intentionally broken fast, you must fast continuously for 60 days. However, if you are unable to do that, then you have to feed 60 poor people at a rate of £6 per person (the cost of two average meals in the Pakistan). As a result, this amounts to £360 for each missed/intentionally broken fast.

Fast a prescribed number of days. But whoever of you is ill or on a journey, then let them fast an equal number of days after Ramadan. For those who can only fast with extreme difficulty, compensation can be made by feeding a needy person for every day not fasted. But whoever volunteers to give more, it is better for them. And to fast is better for you, if only you knew.
Quran 2:184

• Kaffarah costs $480 per missed fast
