Maximum Cost Per Click Calculator

A simple yet effective process for calculating maximum CPC to match-up with estimated keywords CPC..

Max CPC = (ROI per customer) x (1 – projected profit margin) x (website’s conversion rate)

Maximum CPC is determined by the website’s conversion rate, ROI per customer, and projected profit margin.


Conversion rate = 5%
Profit margin = 33%
ROI per customer = Rs.100
So, Max CPC = Rs.100 x (1 – 0.33) x 5% = Rs.3.35

In case the above numbers are missing while setting-up the bid/budget in PPC campaigns, simply start guessing about the figures based on other available source of information and wait for tracking data to get more accurate calculations.
