Today, CNBC published a report stating Spreadsheet errors are costing businesses billions of pounds.
It cites a research done by financial modeling company, F1F9. The company estimated that 88% of all spreadsheets have errors in them, while 50% of spreadsheets used by large companies have material defects, resulting in loss of time and money, damaged reputations, lost jobs and disrupted careers.
The report's top ranked errors included the omission of a minus sign which cost Fidelity Magellan Fund around 1.6 billion ($2.45 billion) in 1995, and the British government's botched efforts to assess bids for the West Coast Rail Line in 2012, which is estimated to have cost around 50 million.
