You can perform you own retirement estimates as often as you like by using the online calculator. However, Merced County Employees' Retirement Association (MCERA) recommends that you request a formal estimate about one year in advance of your anticipated retirement date by submitting a Retirement Estimate Request form. For comparison, there are merits in requesting estimates for various dates.
You can request up to three retirement dates on a Retirement Estimate Request form. The formal estimate will provide estimated benefit amounts for the various benefit payment options. It will also tell you the value of converting your current balance of accrued sick leave to retirement service credit.
