Download excel by clicking the link here!
or , access @downloads on my blog LCDing

3. How to use the tool ?
First read “Readme” sheet in excel. If it makes sense
, try it!
What you need is at least 2-3 years of monthly data
to forecast – the more the merrier!
Follow 3 simple steps

4. Step 1
Just input first month of the past
sales data you have in the format
mmm-yyyy in the cell E10
e.g: January 2006 as Jan-2006
Rest of the months‟ names are
automatically generated

5. Step 2
First delete dummy data
given in the worksheet in
column F from F10 to F81
Now,input sales from cell
F10 …till the present month
(maximum of 180 Months)
As the number of cells in the
column taken for
computations are 192, some
cells in the column may be
found empty. Leave them as
it is…
One Last step to read the
forecast of sales!

6. Step 3
Bingo!
Forecasts
are here!

7. Caution !
Forecasting works on a principle that the future will be like
present ( Similar conditions may prevail ! )
The hope is that near future is not going to be radically
different! ( However, who can predict economic meltdowns and Tsunamis ? )
It is idiocy to forecast sales of next 5 Years when you are not
sure about the present month sales.
Forecasts of distant months (more than 12 Months) could go
grossly wrong.
Despite all, you may find the tool useful !!!
