CALCULATION OF XIRR

How do you calculate your returns when you every year you invest different amount and at the end you receive your Money back? Suppose your invest 1000, 1000, 2000, 2000 and 3000 in 5 yrs and Get 11,000 at the end of 5 yrs then what is your Return? It’s 8%. The concept is called IRR.


WHAT IS IRR?


IRR is Internal Rate of Return and it is used to calculate the returns given some amount at a fixed interval i.e. after every 3 months or after every 1 yr. The only thing which matters is that there should be equal distance between two installments. Compared to XIRR it is easy to calculate and you can find so many online IRR calculators.



WHAT IS XIRR?
IRR does not solve one problem and that is when the payments are at Irregular interval. In that case we use XIRR.

CALCULATION OF XIRR

IN XIRR compared to IRR we will take dates in addition as XIRR is for irregular intervals.  The formula for calculating XIRR is given below



where:
di = the ith, or last, payment date.
d1 = the 0th payment date.
Pi = the ith, or last, payment.


Note: A value of N/A will be returned when using this rate of return if the following conditions are
not met:
1. There must be at least one buy in the account.
2. An iterative technique is used for calculating XIRR. Using a changing rate (starting with
guess), XIRR cycles through the calculation until the result is accurate within 0.000001
percent. If XIRR can't find a result that works after 100 tries, the N/A error value is
returned.


Note: One thing which should be kept in mind while calculating IRR/XIRR is Net Present Value is zero (or We can say cash inflows -cash outflows is equal to zero)
