How Chit Fund Works (Simple Explanation)

Understand the difference between Fixed Increment Chit and Auction Chit with simple examples.

Fixed Increment Chit

The payout amount increases incrementally each month. Monthly installment varies based on the payout for that month. You pay installments for all months, regardless of when you take the chit.

  • Base installment: Chit Amount ÷ Total Members (for Month 1 & Last Month)
  • Month 1 (Organizer) & Last Month: Get full amount (Chit Amount - Commission)
  • Other months: Payout = Base Payout + (Increment × (Month - 2))
  • Monthly Installment = (Payout + Commission) ÷ Total Members
  • Dividend = Base Installment - Monthly Installment (saved by members)
Example (₹1,00,000 chit, 10 members, Commission ₹5,000):
Month 1: Installment ₹10,000, Payout ₹95,000 (Organizer takes)
Month 5: Payout ₹75,000 → Installment ₹8,000, Dividend ₹2,000/member
Month 10: Installment ₹10,000, Payout ₹95,000 (Last member takes)
You take in Month 5: Receive ₹75,000, Pay sum of all installments

Key point: You pay installments for ALL months (1 to 10), even after taking the chit. Early takers get money faster but receive lower payout. Late takers receive higher payout amounts. Your profit/loss = Amount Received - Sum of All Installments Paid.

Auction Chit

Every month, members bid for the chit. The lowest bid wins. The discount (difference between chit amount and bid) is shared as dividend among all members.

  • Base installment: Chit Amount ÷ Total Members
  • Discount = Chit Amount - Winning Bid Amount
  • Dividend per member = Discount ÷ Total Members
  • Your monthly payment = Base Installment - Dividend per member
Example (₹1,00,000 chit, 10 members, Month 5 taker):
Base installment: ₹10,000/month
Month 5 bid: ₹75,000 → Discount: ₹25,000
Dividend per member: ₹2,500
Monthly payment: ₹10,000 - ₹2,500 = ₹7,500
You receive: ₹75,000 (bid amount)

Key point: Your monthly payment varies based on the discount each month. Early takers get lower cash but pay less monthly. Late takers usually get higher bid amounts but may pay more overall.

Simple rule: In Fixed Chit, you pay the same amount every month. In Auction Chit, your monthly payment changes based on discounts. Early takers get money faster but may receive less. Late takers usually get higher amounts but wait longer. Your profit/loss = Amount Received - Total Amount Paid.

Many people face times when they need money quickly. It could be for a hospital bill, family expenses, studies, or an emergency that comes without warning. If they go to a bank for a personal loan, they are often rejected due to low credit score, irregular income, or lack of documents.

Private money lenders are even worse, because they charge extremely high interest, sometimes ₹2 or ₹4 per month per ₹100 borrowed. In such cases, people end up paying only interest for years without ever reducing the principal amount.

For people facing these problems, chit funds can feel like a great alternative.

A chit fund is not like taking a normal loan from a bank. Here, a group of people put in a fixed amount every month. When someone needs money urgently, they can take the full amount earlier from the group.

After taking the money, they still keep paying their monthly amount. Since the payment stays the same every month, it feels easier to handle. Over time, the amount gets settled through these monthly payments, instead of interest increasing like it does with private loans.

Chit funds are also useful for people who struggle to save money. Some individuals may have cash in hand, but if it stays with them, it often gets spent on unnecessary things. A chit fund creates a forced saving habit.

They pay the same amount every month. This builds a habit of saving money.

If they take the chit in the later months, they may get a little extra. It feels like earning some interest.In the end, a chit fund is about people helping each other. Some need money early. Some want a lump sum later, without going to a bank. That said, chit funds are not risk-free.

The main issue with chit funds is trust. If the chit is run by someone you don’t know well, there is always a risk. Sometimes a member may stop paying or leave in between, and then the group has to find a replacement.

This requires an active and responsible group organizer. Without proper handling, the entire system can collapse.

This is why many people prefer running chit funds only with close friends, relatives, or long-term neighbors. When there is mutual trust and accountability, problems can be resolved easily.

There are also registered chit fund companies that work legally. They follow rules and provide documents, but that does not mean they are completely safe. If a company runs into trouble, getting your money back can take a long time and may involve court cases.

Because of this, chit funds should not be treated as a sure way to invest money. They can help in some situations but can also cause problems in others.

People who already have money and are only looking for safe returns may be better off with options like post office recurring deposits, which offer steady interest with much lower risk.

  • when someone urgently needs money and has no access to bank loans
  • when someone wants a disciplined way to save money over time.

But above all, trust is the foundation.

Without trust, a chit fund can become a problem very fast. It is important to know how it works and who you are dealing with. This matters more than quick money or extra returns.
