Chit Fund Calculator
Calculate your chit fund returns, installments, and auction values with precision
Comprehensive Guide to Chit Calculator Formula in Excel
Chit funds are a popular savings and borrowing instrument in India that combine the benefits of regular savings with access to lump sum amounts when needed. Understanding how to calculate chit fund returns, installments, and auction values is crucial for making informed financial decisions. This guide will walk you through the chit calculator formula in Excel, helping you create your own chit fund calculator spreadsheet.
Understanding Chit Fund Basics
A chit fund is a type of rotating savings and credit association where a group of people come together to pool their money through monthly contributions. Each month, the collected amount (minus the foreman’s commission) is auctioned to the lowest bidder, who gets to take home the prize money.
Key Components of Chit Funds
- Chit Amount: The total value of the chit (e.g., ₹1,00,000)
- Duration: Number of months the chit runs (typically 12-50 months)
- Monthly Installment: Fixed amount paid by each subscriber
- Foreman Commission: Percentage deducted from the prize amount (usually 5%)
- Auction Discount: The bid amount that determines who gets the prize money
- Dividend: The difference between chit amount and auction amount, distributed to subscribers
How Chit Funds Work
- Group of subscribers agree on chit amount and duration
- Each subscriber pays monthly installments
- Each month, the collected amount is auctioned
- Lowest bidder gets the prize money (after commission)
- Dividend is distributed among all subscribers
- Process repeats until all subscribers have received their prize
Chit Calculator Formula in Excel
To create a chit calculator in Excel, you’ll need to understand and implement several key formulas. Here’s a step-by-step breakdown:
1. Basic Chit Fund Parameters
Start by setting up your basic parameters in Excel:
| Parameter | Example Value | Excel Cell |
|---|---|---|
| Chit Amount | ₹1,00,000 | B2 |
| Duration (months) | 20 | B3 |
| Foreman Commission (%) | 5% | B4 |
| Number of Subscribers | 20 | B5 |
2. Calculating Monthly Installment
The monthly installment is calculated by dividing the chit amount by the duration:
=B2/B3
For our example: ₹1,00,000 / 20 months = ₹5,000 per month
3. Calculating Prize Amount After Commission
The prize amount available for auction is the chit amount minus the foreman’s commission:
=B2*(1-B4/100)
For our example: ₹1,00,000 × (1 – 5%) = ₹95,000
4. Auction Process and Dividend Calculation
The auction process determines who gets the prize money each month. The key formulas are:
Auction Amount (Bid Amount): This is the amount the winning bidder is willing to accept (less than the prize amount)
Dividend per Subscriber: The difference between the prize amount and auction amount, divided by the number of subscribers
=((B2*(1-B4/100))-AuctionAmount)/B5
For example, if someone bids ₹80,000 for a ₹95,000 prize amount with 20 subscribers:
(₹95,000 – ₹80,000) / 20 = ₹750 dividend per subscriber
5. Net Amount Received by Winner
The net amount received by the auction winner is:
=AuctionAmount-(B2/B3)
This is because the winner still needs to pay their monthly installment. For our example with an ₹80,000 bid:
₹80,000 – ₹5,000 = ₹75,000 net amount received
6. Total Amount Paid by Subscribers
Each subscriber pays monthly installments for the entire duration:
=B3*(B2/B3)
For our example: 20 months × ₹5,000 = ₹1,00,000 total paid
7. Effective Interest Rate Calculation
Calculating the effective interest rate is more complex. You can use Excel’s RATE function:
=RATE(B3,-(B2/B3),-NetAmountReceived)*12
Where NetAmountReceived is the amount the winner actually gets to use.
Advanced Chit Fund Calculations in Excel
For a more comprehensive chit calculator, you can create a month-by-month breakdown:
| Month | Installment Paid | Prize Amount | Auction Discount | Dividend Received | Net Cash Flow | Cumulative Paid |
|---|---|---|---|---|---|---|
| 1 | ₹5,000 | ₹95,000 | ₹15,000 | ₹750 | ₹79,250 | ₹5,000 |
| 2 | ₹5,000 | ₹95,000 | ₹12,000 | ₹600 | ₹5,000 | ₹10,000 |
| … | … | … | … | … | … | … |
| 20 | ₹5,000 | ₹95,000 | ₹0 | ₹0 | ₹90,000 | ₹1,00,000 |
To create this table in Excel:
- Set up columns for each parameter
- Use the monthly installment formula for all months
- For the prize amount column, use:
=$B$2*(1-$B$4/100)
- For the auction discount, you’ll need to input the actual bid amounts (these can’t be calculated without knowing the bidding pattern)
- For dividend received:
=IF(Month=AuctionMonth, (PrizeAmount-AuctionAmount)/$B$5, (PrizeAmount-AuctionAmount)/$B$5)
- For net cash flow:
=IF(Month=AuctionMonth, AuctionAmount-Installment, Dividend-Installment)
- For cumulative paid:
=SUM($B$10:B10)
(assuming installments start at row 10)
Comparing Chit Funds with Other Investment Options
To understand whether chit funds are right for you, it’s helpful to compare them with other investment options:
| Parameter | Chit Funds | Recurring Deposits | Mutual Funds SIP | Fixed Deposits |
|---|---|---|---|---|
| Liquidity | High (can get lump sum early) | Low (locked until maturity) | Medium (can redeem with exit load) | Low (premature withdrawal penalty) |
| Returns | Varies (8-15% typically) | Fixed (5-7% typically) | Market-linked (7-12% typically) | Fixed (5-7% typically) |
| Risk | Medium (depends on organizer) | Low | Medium to High | Low |
| Tax Benefits | None | None (except 5-year tax-saving RDs) | ELSS funds have tax benefits | None (except 5-year tax-saving FDs) |
| Flexibility | High (can choose when to bid) | Low | High (can stop anytime) | Low |
| Minimum Investment | Varies (typically ₹5,000+ per month) | Low (₹100+ per month) | Low (₹500+ per month) | Varies (₹1,000+ typically) |
Legal Aspects of Chit Funds in India
Chit funds in India are regulated by the Reserve Bank of India under the Chit Funds Act, 1982. Key legal aspects include:
- Only registered chit fund companies can operate legally
- Chit agreements must be in writing and registered
- The maximum commission a foreman can charge is 5% of the chit amount
- Chit funds cannot accept deposits from the public
- States have their own chit fund regulations in addition to the central act
The Ministry of Corporate Affairs maintains a list of registered chit fund companies. It’s crucial to verify that any chit fund you consider participating in is properly registered and compliant with all regulations.

Real-World Example: Calculating a ₹1,00,000 Chit Fund
Let’s walk through a complete example using our calculator:
Input Parameters:
- Chit Amount: ₹1,00,000
- Duration: 20 months
- Foreman Commission: 5%
- Number of Subscribers: 20
- Expected Auction Month: 10
- Expected Discount: 20%
Calculations:
- Monthly Installment: ₹1,00,000 / 20 = ₹5,000
- Prize Amount: ₹1,00,000 × (1 – 5%) = ₹95,000
- Expected Auction Amount: ₹95,000 × (1 – 20%) = ₹76,000
- Dividend per Subscriber: (₹95,000 – ₹76,000) / 20 = ₹950
- Net Amount Received: ₹76,000 – ₹5,000 = ₹71,000
- Total Amount Paid: 20 × ₹5,000 = ₹1,00,000
Month-wise Breakdown (partial):
| Month | Installment | Prize Amount | Auction Amount | Dividend | Net Cash Flow | Cumulative |
|---|---|---|---|---|---|---|
| 1-9 | ₹5,000 | ₹95,000 | – | ₹950 | -₹4,050 | Varies |
| 10 | ₹5,000 | ₹95,000 | ₹76,000 | ₹950 | ₹71,000 | ₹50,000 |
| 11-20 | ₹5,000 | ₹95,000 | – | ₹950 | -₹4,050 | ₹1,00,000 |
Effective Interest Rate:
Using Excel’s RATE function for the net amount received:
=RATE(10,5000,-71000)*12 = ~14.5% annualized
Alternative Chit Fund Calculation Methods
While Excel is powerful, there are alternative methods to calculate chit fund returns:
Manual Calculation
For simple chit funds, you can do manual calculations:
- Calculate monthly installment = Chit Amount / Duration
- Calculate prize amount = Chit Amount × (1 – Commission%)
- Estimate auction amount = Prize Amount × (1 – Discount%)
- Calculate dividend = (Prize Amount – Auction Amount) / Subscribers
- Net receipt = Auction Amount – Monthly Installment
Online Calculators
Several financial websites offer chit fund calculators:
- BankBazaar chit fund calculator
- PolicyBazaar chit fund calculator
- Various chit fund company websites
These provide quick estimates but may lack customization options.
Mobile Apps
Several mobile apps are available for chit fund calculations:

These often include additional features like payment reminders and auction tracking.
Tax Implications of Chit Funds
Understanding the tax treatment of chit funds is important for accurate calculations:
- Dividend Income: Dividends received from chit funds are taxable as “Income from Other Sources”
- Capital Gains: The difference between the amount received and installments paid may be considered capital gains in some cases
- Deductions: Monthly installments are not eligible for any tax deductions under Section 80C or other provisions
- TDS: Chit funds may deduct TDS on dividends if they exceed ₹5,000 in a financial year
For detailed tax implications, consult the Income Tax Department website or a qualified tax advisor.
