Based on quarterly data released by the US Treasury, the debt at the end of 2008 — just before Obama took office — stood at roughly $10,699,805,000,000. As of the third quarter of 2016, the most recent data available, the debt as Obama is set to leave office stood at $19,573,445,000,000. Based on the website USdebtclock.com, which extrapolates the US national debt in real time based on committed government spending, the debt will be roughly $19.97 trillion when President-elect Donald Trump takes office on Friday. Thus, the national debt under Obama will have grown by about $9 trillion, or an increase of 86%. Some of this debt is attributable to bills passed by Obama's predecessor, George W. Bush, since the federal government's fiscal year budget operate differently from the calendar year. Also, both Bush and Obama rolled out large investment bills to help the US recover from the depths of the financial crisis.
