This calculator returns the CAGR value based on Chit fund cash flows using Excel’s XIRR and IRR functions. Even if you have no interest in chit funds (good for you!), if you are someone who uses Excel to calculate returns (of any financial instrument), I strongly urge you play with this calculator as it highlights the limitations of estimating returns for complex cash flows.
Reader R. Siva Prasad, requested that I make this calculator to try and make sense of chit fund returns. Earlier, reader Hari sent a video link which pointed out the limitations of XIRR and IRR when he saw my Investment Returns (XIRR) Calculator
Motivation: I am not a fan of chit funds. I did this for two reasons: Siva Prasad requested it and I saw it as a perfect example for illustrating the limitations of calculating returns for complex cash flows and therefore of the XIRR and IRR functions! No fault of Excels. That is just the way the cookie crumbles.
Chit fund Primer: The way a chit fund operates amazes me. A group of people get together and decide to pay an equal sum of money for a few months. Each month the group members bid on the total amount collected. The person with the lowest bid receives the amount after deducting commission or operating charges and can no longer take part in the bidding. The remaining amount is distributed equally to all the members.
How the calculator works functions:
- CAGR using Excels IRR: If you wish to assume the payment and receipts each month are made on the same date then you need not enter the dates of payment and receipts. However,I strongly suggest that you do.
- CAGR using Excels XIRR: In this case the dates of payments and receipts should be entered (along with amounts of course!).
- Observe the results!
Use this calculator to
- advice your friends or clients not to use chit funds.
- think about the limitation of XIRR and IRR!
Bottom line: Do not enter into chit fund schemes looking for returns. It is one thing to get poor returns, quite another when you cannot even calculate them!
