Committee (BC) Calculator
See the payout, the month you collect and what you pay in a committee (BC or ROSCA), round by round.
One payout per member, so this is also the number of months (or rounds).
Payout when it's your turn
Rs 200,000
- You collect in
- Feb 2027 (round 4)
- You pay in total
- Rs 200,000 over 10 rounds
- Paid out ahead of your contributions
- Rs 120,000
10 members paying Rs 20,000 a round make a pot of Rs 200,000. You collect it in Feb 2027, having paid Rs 80,000; you then pay Rs 120,000 more. Everyone pays and receives exactly Rs 200,000, so no one gains or loses money.
How it's worked out
- The pot each round
10 members × Rs 20,000Rs 200,000 - Paid in by your turn
4 rounds × Rs 20,000Rs 80,000 - Still to pay after you collect
6 rounds × Rs 20,000Rs 120,000

- An early turn works like an interest-free loan from the group; a late turn works like saving. Agree the order, the date and what happens if someone stops paying, in writing, before you start.
How it works
Payout = members × amount each round · Total you pay = the same payout, spread over every round
Worked example
Ten members each pay Rs 20,000 a month, so each payout is Rs 200,000. If your turn is fourth, you've paid Rs 80,000 by the time you collect, and you pay the remaining Rs 120,000 over the next six months.
Questions people ask
How does a committee (BC) work?
A group agrees to pay the same amount each month. Every month one member takes the whole pot, until everyone has had a turn. With 10 members paying Rs 20,000, each turn pays Rs 200,000.
Does anyone gain or lose money?
No. Everyone pays in and receives exactly the same total. An early turn is like borrowing from the group with nothing extra to repay; a late turn is like saving.
Is a committee halal?
A committee where everyone pays and receives the same amount, with no extra charge, is widely regarded as permissible. Charging extra for an early turn, or bidding for turns, changes that.
What if a member stops paying?
That's the main risk. Agree the order, dates and what happens if someone drops out, in writing, before the first round.
