"A vote to leave the EU would be the start, not the end, of a process. It could lead to up to a decade or more of uncertainty," the report by British civil servants and government officials said.
The process of agreeing on the terms of withdrawal if the country was to vote in favour of an exit from the 28-member bloc in the June 23 referendum would hit financial markets, the pound and 2 million British citizens based outside the country, The Guardian reported, citing the analysis.
The document says they would only be completed at the end of a three-stage process that will be triggered in June if Britain votes to leave the EU in the planned referendum.
"This government analysis shows that leaving the EU would lead to a decade of damaging uncertainty. The risks to our economy are clear and would leave the jobs and prosperity of the British people dangerously exposed," UK Cabinet Office minister Matthew Hancock said.
The government argues that British trade would also be plunged into uncertainty as it would become necessary to renegotiate individual deals with more than 50 countries that have an arrangement with the EU.
The Cabinet is split over the issue with 17 full members in favour of staying in the EU and five wanting to leave.
Cameron yesterday warned that gaps in the case for a "Brexit" made it the "gamble of the century".

Chris Grayling, the leader of the Commons, who is one of five Cabinet ministers campaigning to leave the EU, said: "People will not be impressed with this relentless campaign of fear. Claims that it will take twice as long to sort out a free trade deal with the EU as it did to win world war two are clearly ludicrous.
"It isn't true. The real uncertainty is voting to stay in an EU, which is already struggling with the euro crisis, the migration crisis, and a youth unemployment crisis. It is safer to take back control and spend our money on our priorities."
The government's official policy is that Britain should remain in the EU - and civil servants are duty-bound to support government policies.
