What were the outcomes of the American revolution?

The primary outcome of the American Revolution was the independence of fourteen formerly British colonies in North America; thirteen of which would immediately form the United States and the fourteenth, Vermont, which would accede to the United States shortly thereafter.
An additional outcome of the American Revolution was an ideological cleansing of royalists in the fourteen formerly British colonies, many of whom were compelled to relocate to Canada. Among these were a number of slaves who had fought on the side of the British.
The Six Nations Confederacy, a 500-year-old alliance of the Seneca, Cayuga, Onondaga, Oneida, Tuscarora, and Mohawk tribes, was also splintered and ended as a result of the American Revolution, the Oneida and Tuscarora having sided with the Americans, with the other tribes having made a ruinous decision to ally with the defeated British.
Returning French soldiers evangelized some of the ideological underpinnings of the American Revolution in Europe through groups such as the Society of the Thirty. This proselytizing encouraged, in part, the later French Revolution with the Declaration of the Rights of Man and the Citizen inspired heavily by the United States Declaration of Independence.

There were many outcomes of the American Revolution. The immediate result was the achievement of independence from Great Britain for the colonies. Longer-term effects include the creation of the United States after the ratification of the Constitution in 1787, the influencing of the French Revolution, beginning in 1789, and the expansion of the territory of our new country Westward. This last effect, the expansion of US territory, made it possible for the new country to absorb large numbers of immigrants. It also created conditions for a significant expansion of slavery in the US, which set the stage for the US Civil War, which began in 1860.
Other outcomes, which had mainly international effects, were the growth of trade and industry related to cotton, as its cultivation increased, along with slavery in the American South, the growth of banking and manufacturing in New England, and the mid-Atlantic states. The American Revolution also had powerful exemplary effects internationally in the nineteenth- and twentieth-centuries. This means the Revolution was used as an example, or imitated, by rebellions and protests the world over.

The main outcome that came out of the 1783 Treaty of Paris was that the colonists gained their independence from Britain.  The United States gained the territory between the Appalachian Mountains and the Mississippi River.  The new nation was also responsible for paying all of its outstanding debts to British merchants incurred before the war.  Britain still maintained forts along the Great Lakes, which it used to arm Native Americans in the region against encroaching American settlers. This was a clear violation of the treaty.  
Internationally, a spirit of democracy seemed to take hold in the Atlantic World.  Haitian slaves overthrew their French masters in the spirit of all men being created equal.  The United States, afraid that such an uprising would inspire insurrection in Southern slaves, did not recognize the existence of the Haitian nation until 1862.  The French monarchy was bankrupted by helping the Americans in this war, and many commoners sought to overthrow the French thrown. The French Revolution began in 1789, which then transformed into the Reign of Terror. Ultimately, this would lead to the rise of Napoleon and a very costly war which engulfed all of Europe.  
As a result of the American Revolution, other colonies of European powers sought their independence, often using the same rhetoric of the Declaration of Independence.  As late as the twentieth century, Ho Chi Minh, the leader of North Vietnam, created the Vietnamese Declaration of Independence; he sought to create a nation of equality under the law that did not have to worry about foreign interference.  He used a great deal of the rhetoric used in the Declaration of Independence—demonstrating the continuing influence of the colonists' struggles in 1776.
