How google deduct bidding amount.

Let have an example :-  Google is running ads for top of page bid position

1. A Advertiser Put his bid (Default CPC Cost per click) :- 10
2. B Advertiser Put his bid (Default CPC Cost per click) :-10
3. C Advertiser Put his bid (Default CPC Cost per click) :- 10

Google deduct bidding acmount on the basis of adrank, Then how much cost/amount for 1st Position advertiser when someone click on that ads.

Formula for Ad rank:- Max CPC * Keywords Quality Score

A advertiser :- 

      Max CPC :- 10

      Quality Score :- 10

Ad Rank for A ;- 10*10 = 100

B advertiser :- 

      Max CPC :- 10

      Quality Score :- 8

Ad Rank for B ;- 10*8 = 80

C advertiser :- 

      Max CPC :- 10

      Quality Score :- 5

Ad Rank for C ;- 10*5 = 50

Actual CPC deduct:-  Ad rank of your nearest competitor/your quality score + 0.01

                                      

                                       80/10+0.01=8.01 Actual CPC for A  

                                        

Exact amount deduct when someone click on A advertiser ad:- 8.01
