The difference between a felony and a misdemeanor is mainly in the severity of the crime and the punishment. These differences affect:
How much your case will cost
How long your case will go on
The amount of jail or prison time you face if found guilty
The amount of fine you could receive if found guilty
Your ability to vote
Your right to serve on a jury
Your ability to possess a firearm
A felony is more expensive, will likely go on longer, have increased jail or prison time, have higher fines, and could take away your ability to vote, serve on a jury, and ability to possess a firearm.
