SJCERA’s Retirement Benefit Calculator is intended to provide an estimate only. It is based on the information you enter and should not be your only source of information for retirement planning. The estimates are non-binding and do not constitute a guarantee of plan coverage, eligibility or benefit amount.  The benefit shown will likely differ from the benefit you receive at retirement.*  Your actual retirement allowance, including optional allowances, will be determined by SJCERA in accordance with Federal and State law when you formally apply for retirement. If there is any inconsistency between the estimate generated by this calculator and the governing law, the law will govern, even if it results in a lower benefit or a later retirement date. When you are within twelve months of retirement, ask SJCERA to provide you an estimate by completing a Request for Estimate form, available on or by contacting SJCERA.
For more information on current rules that may limit the compensation used to calculate your benefit, click on the appropriate following link for your tier: Tier 1 annual compensation limit ; Tier 2 annual compensation limit.

* Because the Retirement Benefit Calculator accounts for Social Security integration for General Tier 1 Members only, the estimate will be overstated for Safety Tier 1 Members who work(ed) for the Lathrop-Manteca Rural Fire Protection District.
