Sir, I tried but failed in my attemptHave you tried the XIRR function?
The year numbers would need to be turned into date serial numbers and I suspect the final return you quote is out by a factor of 10.
Thanx a lot : The rationale is similar to lending where IRR Rule helps companies /lenders decide whether or not to proceed / extend credit with a projectNot being an accountant, I do not know what the convention is but one sign represents in-flows of money and the other out-flows.
