Undated (AP) A new book is estimating the war in Iraq will cost about $12 billion a month this year.

The authors, including a Nobel prize-winning economist, also predict the total cost of the military operations in Iraq and Afghanistan by 2017 could reach $2.7 trillion or more.

They say interest on money borrowed to pay those costs could alone add $816 billion to the bottom line.

The nonpartisan congressional budget office has done its own projections and comes in lower. It's forecasting a cumulative cost by 2017 of $1.2 trillion to $1.7 trillion for the two wars, with Iraq generally accounting for three-quarters of the costs
