Calculation of Reach
Universe: 10 individuals.
For a single episode of Chhoti Maa:
if out of the above 10 people 6 saw atleast 1 minute of the
programme then,
Reach:6 out of 10
Therefore, reach = 60%

• Cumulative Reach
• Net Reach

Gross Reach
•Gross Reach = Summation of all audiences who
have been exposed to the vehicle
•Week 1 : 1000
•Week 2 : 2000
•Week 3 : 1500
•Week 4 : 1200
Hence, Gross Reach = ?
1000+2000+1500+1200=5700

Net Reach
• Week 1 : 1000 -- 1000
• Week 2 : 2000 (300) 2700
• Week 3 : 1500 (900) 3300
• Week 4 : 1200 (1000) 3500

• Principle : Audiences accumulate over time
• The number of individuals within the TG who are
exposed to the medium/vehicle over a certain
period of time

Universe : 11089000
Calculation Explained
Total Time: Avg. minutes ( universe) x Universe
Total Time / Reach = Average Minutes viewer.
Therefore, (1056 x 11089000)/ 10314000= 1135

• People that saw the programme for atleast 1
continuous minute :
A + B+D+E =4
Therefore, Reach=4/5
Reach=80%
