FACTBOX: Details on the White House's new deficit forecasts

(Reuters) - The Obama administration will publish updated budget and economic forecasts next week.

Below are the key figures that are already known:

* The White House budget office will raise its 10-year budget deficit projection by some $2 trillion to approximately $9 trillion, according to an administration official. The previous forecast was $7.108 trillion.

* The administration will trim its projection for the fiscal 2009 budget deficit to $1.58 trillion from $1.84 trillion.

* The main reason for drop in the projected deficit is the elimination of a $250 billion "placeholder" that had been set aside in previous budget forecasts for potential future bank rescues.

* Another $78 billion set aside for the Federal Deposit Insurance Corp to pay for bank failures also will be saved because fewer banks went under than first expected.

* U.S. officials said spending in the 2009 fiscal year would total $3.653 trillion and revenues would be $2.074 trillion.

* The $1.58 trillion deficit would account for 11.2 percent of U.S. gross domestic product -- the highest deficit as a percentage of GDP since 1945.

* In May, the White House pushed up its budget deficit estimates for 2009 to $1.84 trillion -- representing 12.9 percent of GDP.

A White House forecast released in February projected a deficit of $1.75 trillion, or 12.3 percent of GDP.

The 2009 fiscal year ends on September 30.
