6 Dhruva 2016 66.50 82.95 15.30 98.25

Step #2 - Adjust collections based on inflation rate

We all know that movie ticket prices aren't what they used to be. The cost of consumer goods and services rise each year. So, taking inflation into account is the only way to meaningfully compare the box office collection of movies over time. Ideally we should use India inflation rate for adjusting box office collection in India and inflation rate from respective countries for overseas collection. For simplicity, our calculations assume US inflation rate as the basis for adjusting the box office collection of all overseas countries. We also take into account the currency rate change over a period of time to accurately calculate the present box office collection values of historical movies.

Step #2a - Collect data to calculate inflation (courtesy www.worldbank.org, www.wikipedia.org/)

Year India Inflation Rate India CPI (Consumer Price Index)
2012 9.312445605 118.9951729
2013 10.90764331 131.9747419
2014 6.353194544 140.7504026
2015 5.872426595 147.6569875
2016 4.97 154.99553977
2017 0.8 156.235504088
Year US Inflation Rate US CPI (Consumer Price Index)
2012 2.069337265 105.2915045

2014 1.622222977 108.5669321
2015 0.118627136 108.695722

2017 2.5 112.86148554565
Year Average US Dollar to Indian Rupees Exchange Rate
2012 54.4091

2015 64.20012
2016 67.26527
2017 67.69355

Step #2b - Apply inflation

Present box office collection value of historical movies is calculated by using a simple formula:

Collection(y) = ( CPI(y) / CPI(x) ) * Collection(x)

where "x" represents historical CPI and box office collection values and "y" represents current values.

Example domestic calculations for Racha
Racha release year
2012
2012 CPI value
118.9951729
Current CPI value
156.235504088
India collection in 2012
78.15 Cr
Inflation adjusted collection
(156.235504088 / 118.9951729 ) * 78.15 = 102.61Cr
Example overseas calculations for Racha
Racha release year
2012
2012 CPI value
105.2915045
2012 USD to INR exchange rate
54.4091
Current CPI value
112.86148554565
Current USD to INR exchange rate
67.69355
Overseas collection in 2012
2.63 Cr = 2.63/54.4091 = $0.48MM
Present value of collection USD
(112.86148554565 / 105.2915045 ) * 0.48337502366332 = $0.52 MM
Present value of collection INR
$0.52MM * 67.69355 = 3.51 Cr

Total Racha collection in 2012 = 78.15 + 2.63 = 80.78 Cr

Present value of Racha collection = 102.61 + 3.51 = 106.11 Cr

Step #2c - Calculate present value of collection based on inflation for all movies

No Movie Year Inflation Adjusted Tamilnadu Collection Inflation Adjusted Domestic Collection Inflation Adjusted Overseas Collection Inflation Adjusted Total Collection
1 Racha 2012 83.04 102.61 3.51 106.11
2 Naayak 2013 76.95 93.64 3.97 97.61
3 GAV 2014 59.94 72.43 6.12 78.55
4 Yevadu 2014 71.37 85.80 3.36 89.16
5 Bruce Lee 2016 50.90 62.72 8.25 70.97
6 Dhruva 2016 67.03 83.61 15.78 99.40

Step #3 - Calculate expected collection based on weightage

For calculating expected collection for an actor, we give appropriate weightage to the movies based on several factors. The weighted average is used to calculate the expected collection of an actor.
No Movie Year Inflation Adjusted Total Collection Weightage Collection * Weightage
1 Racha 2012 106.11 2.00 212.23
2 Naayak 2013 97.61 2.00 195.22
3 GAV 2014 78.55 1.00 78.55
4 Yevadu 2014 89.16 2.00 178.33
5 Bruce Lee 2016 70.97 1.00 70.97
6 Dhruva 2016 99.40 3.00 298.19
Total 11 1,033.48

Total expected collection for Ram Charan = 1,033.48/11 = 93.95 Cr
