If it’s a good story, who cares about an extra zero? The Daily Telegraph on Tuesday ran a splash saying that by 2015, public sector pensions would be costing every household £4,000 a year.

This came from the Office for Budget Responsibility figures showing that public sector pensions will cost £9.4 billion a year in 2014-15. There are 26 million households, so the cost per household is 9.4 billion divided by 26 million: £361.53.

The Telegraph miscalculated this as £3,615 then rounded it up to £4,000. (Or at least that's what I'm guessing happened.) That’s the version that ran in the paper, below:
 
      
 
 
Catches the eye, doesn’t it, even without the nice picture of Catherine Zeta-Jones alongside? The Telegraph can never be accused of not knowing its readers.
 
If you search the Telegraph website, there are links to both headlines, though the story they link you to has been corrected. It says £400 in both cases.
 

 
 Lesson: teach journalists to divide. It pays dividends.
