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)
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)
2013 1.464832656 106.8338489
2014 1.622222977 108.5669321
2015 0.118627136 108.695722
2016 1.3 110.108766386
2017 2.5 112.86148554565
Year Average US Dollar to Indian Rupees Exchange Rate
2013 60.936
2014 63.469
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 Singam 2
Singam 2 release year
2013
2013 CPI value
131.9747419
Current CPI value
156.235504088
India collection in 2013
95.30 Cr
Inflation adjusted collection
(156.235504088 / 131.9747419 ) * 95.30 = 112.82Cr
Example overseas calculations for Singam 2
Singam 2 release year
2013
2013 CPI value
106.8338489
2013 USD to INR exchange rate
60.936
Current CPI value
112.86148554565
Current USD to INR exchange rate
67.69355
Overseas collection in 2013
27.98 Cr = 27.98/60.936 = $4.59MM
Present value of collection USD
(112.86148554565 / 106.8338489 ) * 4.5917027701195 = $4.85 MM
Present value of collection INR
$4.85MM * 67.69355 = 32.84 Cr

Total Singam 2 collection in 2013 = 95.30 + 27.98 = 123.28 Cr

Present value of Singam 2 collection = 112.82 + 32.84 = 145.66 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 Singam 2 2013 71.03 112.82 32.84 145.66
2 Anjaan 2014 47.73 72.76 22.42 95.18
3 Masss 2015 31.21 52.90 27.20 80.10
4 24 2016 32.76 74.94 32.84 107.79
5 Singam 3 2017 43.00 80.45 26.16 106.61
6 Thaanaa Serndha Koottam 2018 44.00 70.65 22.44 93.09

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 Singam 2 2013 145.66 2.00 291.31
2 Anjaan 2014 95.18 1.00 95.18
3 Masss 2015 80.10 1.00 80.10
4 24 2016 107.79 3.00 323.37
5 Singam 3 2017 106.61 3.00 319.83
6 Thaanaa Serndha Koottam 2018 93.09 3.00 279.27
Total 13 1,389.06

Total expected collection for Suriya Sivakumar = 1,389.06/13 = 106.85 Cr
