CPM = 1000/ 10000 = Rs.0.1
4. CTR Formula / Click Through Rate Formula

E.g. If I have got 500 Clicks & 10,000 Impressions, then my Click Through Rate Formula would be;
=> Click Through Rate = 500/ 10000 *100
=> CTR = 0.05*100
=> CTR = 5%
5. CR Formula / Conversion Rate Formula

E.g. If I have got 10 Conversions by getting 100 Clicks, then my CR Formula would be;
=> CR = 10/100 * 100
=> CR = 0.1 * 100
=> CR = 10%
6. ROI Formula/ Return on Investment Formula
To clarify, ROI calculated on the basis of your total investment on the product including the manufacturing, transportation, taxes & all other miscellaneous costs. So here, As a spent, the calculation will contain the advertising cost along with the manufacturing and other costs.

E.g. If I have got a revenue of Rs. 10,000 on spending a total of Rs. 1000 on Google Advertising & Rs.4000 on the manufacturing & other investment of my product, then my ROI Formula would be;
ROI = (Total Revenue – (Google Advertising Costs + Product Manufacturing & Other Costs)) / (Google Advertising Costs + Product Manufacturing & Other Costs) * 100
=> ROI = (10000 – (1000+4000)) / (1000+4000) * 100
=> ROI = (10000 – 5000)/ 5000 * 100
=> ROI = 5000/ 5000 * 100
=> ROI = 1*100
=> ROI = 100 %
Let’s understand this Google Ads PPC Formula with another example
E.g. If I have got a revenue of Rs. 1,000 on spending a total of Rs. 100 on Google Advertising & Rs.500 on the manufacturing & other investment of my product, then my ROI would be;
ROI = (Total Revenue – (Google Advertising Costs + Product Manufacturing & Other Costs)) / (Google Advertising Costs + Product Manufacturing & Other Costs) * 100
=> ROI = (1000 – (100+500)) / (100+500) * 100
=> ROI = (1000 – 600)/ 600 * 100
=> ROI = 400/ 600 * 100
=> ROI = 0.67*100
=> ROI = 67 %
7. ROAS Formula/ Return on Ad Spend Formula

E.g. If I have got a revenue of Rs. 10,000 on spending a total of Rs. 1,000, then my ROAS Formula would be;
=> ROAS = 10000/ 1000
=> ROAS = 10
That means, in ratio, it is 10:1. So, I can say that my ROAS is 10 times of my spending amounts on running Google Ads Campaigns.
8. Quality Score Formula
QS = The combination of Expected Click Through Rate, Keywords Relevancy & Landing Page Experience
9. Ad Rank Formula

E.g. If I am willing to pay a maximum of Rs. 5 for a click & my Quality Score is 10, then my Ad Rank Formula would be;

=> Ad Rank = 50
So, I can say that my Ad Rank is 50.
10. Actual CPC Formula
Actual CPC = Ad Rank of your nearest competitor/ Your Quality Score +0.01 $
11. Total Cost Formula
Total Cost = Total Clicks * CPC
12. Cost Formula (You can also Calculate like this)
