Need help calculating MAX CPC

Hi everyone I really need help on figuring out MAX CPC. Did research online but everyone seems to have their own formula which makes this all confusing. I have provided the following stat below from my recent AdWords for your reference. Thank you very much!

-Gross sales = $91.73
-Total clicks = 49
-Total advertising cost = $26.05
-Conversion = 30.6% -> 49 clicks divided by 15 sales

 

need your profit margin to calculate anything, gross sales is irrelevant (unless by that you meant affiliate commission)

 

Yes this is affiliate commission. So earnings would be calculated as gross commission or as net commission (minus advertising cost)?

 

your max CPC (at which you would only break even): 91.73/49=$1.87 per click

 

Interesting. I thought Max CPC was calculated as:

MAX CPC = Average Payout * Conversion %

No?

Isn't your formula equal to earnings per click and not MAX CPC?

 

it should give you the same result, just more calculations:
91.73/15*0.306=$1.87

 

Ok got it. Would it make more sense to subtract 91.73-26.05 and then divide by 15? Or it's better to get the gross amount versus the net amount? Thanks!

 

that would give you "by how much can I increase my current CPC" value

 

[100%-(desired ROI in percentage)]*[gross sale/(# of clicks*cost per click)]

try that..
