Calculation for TARPs with ave audience
Calculation: Average Audience/Potential x 100%
GRP or Total TARPs
The total sum of individual TARPs by spot, by market (can’t add up TARPs from different markets)
Average Frequency
Calculation: Total TARPs/Reach%
(Total TARPs) 50 divided by (Reach %) 40 = 1.25x (Average Frequency).
Reach (as a percentage)
Calculation: Reach/Universe Estimates (Potential) x 100%
CPR
Cost per reach
Total budget/reach
E.G. $100,000/40 = $2,500
CPT
Calculation: Cost of spot/TARP
Audience Profile %
Calculation: Target group audience / Total People Audience
Media Levy
0.05%
Gross to Net
Gross x 0.9
Net to Gross
Net / 0.9
Daypart splits
Example: 100 TARPs are to be run as 70% Peak & 30% Off Peak.
Peak = 100 x 0.7 = 70 TARPs
Off Peak = 100 x 0.3 = 30 TARPs
Duration splits
The % of TARPs to be allocated to each duration.
Example: 100 TARPs are to be run as 80% 30s & 20% 15s.
30s = 100 x 0.8 = 80 TARPs
15s = 100 x 0.2 = 20 TARPs

Calculate TARPs
Calculation: Reach x Frequency
Converting a CPT to CPM
Converting a CPT to a CPM
Calculation: CPM = (CPT x 100)/Potential in 000’s
Example: if CPT is $800 in Sydney for W25-54 and the potential is 1,142,000
You would multiply the CPT $800 x 100 and then divide by the potential (in ‘000’s) of 1,142 your
CPM would be $70.05
$800 x 100 = $80,000
$80,000/1142 = $70.05
Converting CPM to a CPT
Converting a CPM to a CPT
Calculation: CPT = (CPM x potential in 000’s)/100
Example: to calculate the CPT in Sydney for W25-54
CPM $70.05 x 1,142 (the potential in ‘000’s) and divide by 100 your CPT would be $800
$70.05 x 1,142 = $79,997.10
$79,997.10/100 = $799.97 = $800
