Definition of vesting. : the conveying to an employee of inalienable rights to money contributed by an employer to a pension fund or retirement plan especially in the event of termination of employment prior to the normal retirement age; also : the right so conveyed.
Vesting refers to ownership. Another way of looking at it is, if you have $10,000 in your retirement plan and you are 30% vested, you own $3,000. Your vested portion can never be reduced. If you leave your employer, the vested portion of your account can go with you or (in some cases) you can cash it out.
