Hi Suzanne
Compound Average Growth Rate?
i = (FV/PV)^(1/n)-1
Where:
FV = Value at end of periods counted by n
PV = Value at start of periods counted by n
n = number of periods
i will be the rate per period.
You can calculate variously in Excel.
From formula above.
Or:
=RATE(nper,pmt,pv,fv,type,guess)
Note that starting value (PV) is input as negative and end value (FV)
as positive. The rate returned will be the rate per period counted by
NPER argument
Or:
=XIRR(values,dates,guess)
Returns the annual effective growth rates.
All are fairly well covered in Help but by all means give a few
examples of your dates and the figures and they can be slotted into
formulas with appropriate proofs and checks that all is working OK.
