The TRF Optional Service Credit Purchase Calculator allows the calculation of your unofficial
cost of buying service credit. This is not an official cost, and there is no guarantee on the estimated amount.
This calculator should only be used as a preliminary tool to help you understand the potential cost of service credit.
Further, the purchase of service credit is permitted only in limited circumstances. Please note that if you are pursuing
Military or Out of State service, and you currently have less than 10 years of creditable service, an estimated cost will
not be calculated. You can find additional information on permitted service credit purchases
