Chit Fund Calculator
This chit fund calculator estimates your average monthly payment, dividend and total savings on an Indian chit fund — a rotating savings scheme where a group of members each pay a fixed monthly installment, and one member is paid the full pooled amount every month via auction. Enter your chit's value, member count, average bid discount and the foreman's commission to see a simplified average-case outcome across the full tenure.
The total pooled amount your chit group contributes toward and pays out to one member each month.
A chit runs for as many months as it has members — one member is paid out each month. A ₹1,00,000 chit with 25 members runs 25 months with ₹4,000 monthly installments.
The average percentage of the chit value that winning members forfeit when they take the prize early — typically 15-30%, higher in the earlier months and lower toward the end.
The chit fund company/organizer's fee, usually around 5% of the chit value, deducted from the discount pool before it's distributed as dividends.

How to use this chit fund calculator
- 1Total chit value: the full pooled amount paid out to the winning member each month.
- 2Number of members: how many people are in the chit — this also sets the duration in months, since one member wins each month.
- 3Average bid discount: the average percentage of the chit value that winning members forfeit in the auction — typically 15-30%, higher in early months and lower toward the end.
- 4Foreman's commission: the organizer's fee, usually around 5% of the chit value, taken out of the discount pool before the rest is distributed as dividends.
Understanding your results
Average monthly payment is your typical net outflow after the dividend is subtracted from the fixed installment, averaged across the whole tenure — your actual payment varies month to month depending on that month's winning bid. Total paid over tenure extrapolates that average across the full duration. Effective savings compares that total to what you'd have paid with no dividend at all — the value of the bidding pool over a plain fixed-installment loan of the same size.
The formula
Payable installment = Original installment − (Bid discount − Commission) ÷ Number of membersEach month, the winning member's forfeited bid discount, minus the foreman's commission, is pooled and split evenly among the other members as a dividend — this reduces what everyone else effectively pays that month. This calculator applies that formula using your average discount percentage across the whole tenure, rather than simulating each month's real auction result, since actual bids vary a lot from month to month — typically higher in early months when more members compete to win early, and lower in late months when fewer members still need the payout.
A worked example
A ₹1,00,000 chit with 25 members runs 25 months, with a ₹4,000 fixed monthly installment. At a 20% average bid discount and 5% foreman's commission: the average bid discount is ₹20,000, commission is ₹5,000, leaving ₹15,000 to distribute — ₹600 per member. That brings the average monthly payment down to ₹3,400, for a total of ₹85,000 paid across the 25 months — a ₹15,000 effective saving versus paying the plain ₹4,000 installment every month with no dividend.
Things to know
This is a simplified, average-case model, not a month-by-month simulator — real chit funds vary significantly depending on which month you actually win the auction. Winning early gets you a lump sum sooner but at a steep discount, with little to no dividend benefit for the rest of the tenure; winning late gets you close to the full chit value plus the dividend benefit accumulated from months you didn't win, but ties up your money the longest. Chit funds also carry real counterparty and default risk, unlike government-backed schemes such as PPF or NSC — the foreman or other members can default, and unregistered or informal chit schemes offer little recourse. Only participate through RBI/state-registered chit fund companies operating under the Chit Funds Act, and verify registration before committing money.
Frequently asked questions
How is a chit fund different from a fixed deposit or recurring deposit?+
An FD or RD pays you a fixed, guaranteed return with no counterparty risk beyond the bank. A chit fund instead pools members' contributions and rotates the payout via auction, so your effective cost or return depends on when you win — it can beat an FD/RD in some scenarios, but it also carries organizer and default risk that a bank deposit doesn't.
Is my money safe in a chit fund?+
Only if it's run by an RBI/state-registered chit fund company operating under the Chit Funds Act. Unregistered or informal chit schemes offer little legal recourse if the foreman or a member defaults — always verify registration before joining.
Should I try to win the auction early or late?+
Winning early gives you a lump sum sooner, useful if you need the money, but at a steeper discount and little dividend benefit. Winning late means a smaller discount (closer to the full chit value) plus dividends collected from earlier months, but your money stays locked in longer — the right choice depends on whether you need cash now or are optimizing for total return.
How accurate is this calculator's estimate?+
It's a simplified, average-case model using one flat bid-discount percentage across the whole tenure. Real chit funds see bids vary a lot month to month, so treat the results as a rough approximation of your average cost, not a month-by-month prediction.
