The process of planning for retirement, specifically in terms of making financial plans. Most often, retirement planning involves depositing money into a retirement account, and purposefully saving money for the future. There are many different types of retirement plans available, including an Individual Retirement Account (IRA) and a 401(k) plan. In most cases, employees are provided with a retirement plan by their employer, and contributions to the plan are deducted from the employee's paycheck. Some employers will match a certain percentage of an employee's contributions, adding more money to their account. Most plans have different rules and guidelines, including details such as when the money can be withdrawn.
