How can you predict your sales in a year with a statistical method?

Question

for examlple I have 2006 sales were of 300; 2007 sales were of 100 and 2008 sales were 209. How can I know aproximately what the sales are going to be in 2009?

Answer 1

You'd have to run it against other statistical variables.  For example, were there more client renewals due in 2006?  Did you make more client calls in 2006?   You need something to compare the data against.

I find once you remove the renewals, you can't predict with terrible accuracy.  There are too many outside variables impacting sales and I find often it's simply a matter of staying with it and staying in touch with customers and prospects.

Three sites that seem to have a lot of statistical research and you may be able to find answers: millerheiman.com, salesguy.org, bdmnews.com.

Answer 2

You could run a best-fit regression - the following web site has instructions:
