Qada Calculator: How Many Prayers Have I Missed?

Q: How do I calculate how many prayers I have missed?

Estimate the years between when prayer became obligatory for you (puberty) and when you began praying consistently, subtract any periods you did pray, then multiply the missed years by 365 days and 5 prayers per day. Women subtract average menstruation days. When unsure, most scholars advise estimating on the higher side.

Q: Do I really have to make up years of missed prayers?

The four Sunni schools hold that deliberately missed obligatory prayers should be made up (qada) alongside sincere repentance. Some later scholars emphasized repentance and voluntary prayers instead. Ask a local imam or scholar you trust for your personal situation — but no position treats missed prayers as simply forgotten.

Q: How long does it take to finish qada prayers?

At one extra day's worth of prayers per day (5 qada daily), one year of missed prayers takes about a year to repay. Adding one qada prayer after each obligatory prayer clears roughly 1,825 prayers per year. The pace matters less than never letting the count grow again.

If you're asking "how many prayers have I missed?", you're already doing the brave part. This qada calculator turns years into a concrete number — and a concrete number is the beginning of a plan, not a verdict. Estimate honestly, start small, and let the count go down instead of up.

The calculator

Enter your best estimate of the years you weren't praying (or were praying inconsistently — count the missed portion). The math is simple: years × 365 days × prayers per day.

How to estimate your missed years honestly

Nobody kept a spreadsheet through their teens. Scholars have always recognized this, which is why every school allows — in fact requires — a good-faith estimate. Work through it in four steps:

Find your starting line. Prayer became obligatory at puberty. If you can't pin the year, scholars commonly use a reasonable assumption in the early teens — many use around age 12–15. When unsure, choose the earlier age so you don't undercount.
Find your finish line. The point when you began praying all five prayers consistently — not perfectly, consistently.
Subtract what you did pray. If you prayed Fridays only, or Ramadan only, or Fajr and Maghrib for a stretch, subtract honest fractions. "I prayed maybe 2 of 5 for three years" means counting 3 of 5 for those years.
Women: subtract menstruation. Prayers during menstruation are not owed and are not made up. Subtracting your average days per month (the calculator's third field) is the standard approach.

How the madhabs treat the estimate

The four schools agree that deliberately missed obligatory prayers remain a debt to be repaid, and all of them accept estimation where records don't exist — but their emphasis differs slightly:

Hanafi: act on your strongest supposition (ghalabat al-zann) — a settled best estimate is sufficient. Witr is considered wajib, so missed witr is made up too (choose "6" above).
Shafi'i and Hanbali: repay until you're reasonably certain the debt is cleared — which in practice means rounding your estimate up rather than down.
Maliki: similar reliance on considered judgment; err on the side of more when in doubt.

A minority of later scholars held that sincere repentance plus abundant voluntary prayer suffices for prayers missed deliberately. Because rulings differ and your history is personal, ask a local imam or scholar you trust — then commit to one approach and stop re-litigating the number.

The number is not the point — the direction is

Ten years of missed prayers is roughly 18,000. Seeing that number can either crush you or clarify things, and Islam firmly intends the second. You are not asked to repay it this month. You are asked to stop the count growing (guard today's five first) and to chip away steadily — one qada after each obligatory prayer is the classic pace, clearing about a year's backlog per year. The Prophet ﷺ taught that the most beloved deeds to Allah are the most consistent, even if small. That principle was practically made for qada.

Common estimation mistakes

Counting from birth. The debt starts at puberty, not at birth — don't add years you never owed.

Forgetting partial years. Most people didn't stop and start cleanly. Fractions are fine; the estimate just has to be honest.

Recounting forever. Estimate once, carefully, ideally after speaking with a scholar. Then write the number down and never redo the math. Endless recalculation is a door to despair, and despair is exactly what shaytan wants from this exercise.

Repaying the past while losing the present. A qada plan that exhausts you into missing today's Fajr is a bad plan. Today's five prayers come first, always.

FAQ

How do I calculate how many prayers I have missed?

Years between puberty and consistent prayer, minus what you did pray and (for women) menstruation days, times 365, times 5 (or 6 with witr in the Hanafi school). The calculator above does the arithmetic; the honesty is your part.

Do I really have to make up years of missed prayers?

The four schools say yes — qada plus repentance. A minority of later scholars emphasized repentance and voluntary prayers. Ask a scholar you trust for your own ruling, then commit to it.

How long does it take to finish qada prayers?

One extra day's worth of prayers per day repays one missed year per year. It's a long road by design — what matters is that the number only moves in one direction.
