Calculate Newsletter Signups Ratio

Hi Guys,
Im trying to figure out from my intranet traffic and news letter sign ups, the sign up ratio between Cellphone and Desktop in Excel.

I need a formula that calculates for every X cellphone visits I get 1 newsletter signup and for every X desktop visits I get 1 newsletter signup.

I would have something like this "Every 10 cellphones visits = 1 newsletter signup" and "Every 5 Desktop = 1 newsletter signup"

Do I simply divide cellphones and desktop signups  by intranetvisits ?

Thanks
jay


Newsletter Signups,

                   Week1            Week2            Week3            Week4
CellPhones      110                       90                    113                     134      
Desktops              234                      300            310                     320
Total SignUp      344                      390            423                     454

IntranetVisits 2040            2400            2521            2701

Yes. For example you have 234/110 = 2.127 desktops per cell phone for week 1.
For week 1, 234/110 = 2.12 which means 2.12 desktop signups for every cellphone signup
I would think you need something like:

=B2/10+B3/5

where B2 is Cellphones for Week1 and B3 is Desktops for Week1,

You can copy formula across the other weeks.
Note that if you keep your units it makes sense mathematically.
For example 2040 visits/344 signups = 5.9 visits/1 signup or 5.9 visits for every 1 signup.
For week 1, 110/234 = 0.47 which means 0.47 cellphone signups for every desktop signup

The total number of intranet visits is irrelevant for your purposes.

Use these calculations fo a nice pie chart in excel
234/344 = 0.68 = 68% Desktop
110/344 = 0.32 = 32% Cellphone
