Calculating Yearly Gains

From: Glenn Mott


I am trying to calculate the average yearly gains for suburbs from data given at http://www.reiwa.com.au and would like to know if anyone could suplly a formula given the following:

Present value = x dollars
Past value = y dollars
Time = z years

Average yearly gain = ?

Thanks in anticipation...

yearly gain = g ie 1.08
present value = x
past value = y
time = z years


g to the power of z = x/y

therefore g = x/y to the power of 1/z

(ie for z = 4 years then 1/z = 0.25)
