So, from 3.0% increase one year ago, to a proposed 6.2% increase 1Q13/1Q12.
The trouble with your numbers from a year ago is that a year ago DISH also increased their rates by "about $5" across the board. Which would naturally be a higher increase than the proposed $5 increase this year. ($75 to $80 is a higher percentage increase than $80 to $85.)
Increasing rates by 6% does not increase ARPU by 6%. Such a claim would be false.
One of the reasons why is that DISH is *NOT* increasing all rates by 6%. Even if they raised all package prices by $5 that does not raise the additional receiver fees and other add ons by the same percentage as the core packages. Plus consumers react to price increases. After the 2013 price increase some consumers scaled back their subscriptions (as reported by representative consumers on the Internet). In response to the price increase they lowered the revenue they sent the company.
Which is why the 2013 price increase of "about $5" turned in to an ARPU increase of less.
The 2013 price increase was $5 on most packages (7 to 11%), $10 on AT120+ (20%) and $15 on AEP (14%). That did not translate into a 7%+ increase in ARPU.
