Generally, if you are a non-retired Tier III or IV member, you may use this feature to obtain estimates of the cost to purchase your eligible prior service credit with a single lump-sum payment by check or through various payment plans of payroll deductions. (Prior service is service that you performed with a New York City and/or a New York State public employer before joining TRS and that was not transferred to TRS.)
Even if otherwise eligible, you may not be able to use the calculator for one of the following reasons:
- According to our records, you do not have any verified prior service credit eligible for purchase.
- You are currently purchasing your eligible prior service credit through a payment plan.
- You have recently requested a Cost Letter.
- TRS is revising your current payment plan after receiving additional information.
Start and End Dates: You may enter the start and end dates of the prior service by clicking the calendar to select a date, or type in the date directly in MM/DD/YYYY format.
Salary Earned: Enter the salary you earned for the period of prior service you entered. Do not enter a dollar sign, comma, or decimal point. Do not enter an annual salary unless the period of prior service above equals one year.
Payment Option: Select a payment option: lump-sum payment by check, biweekly payroll deductions, or semimonthly payroll deductions. (If you are paid biweekly, you receive 26 paychecks each year; if you are paid semimonthly, you receive 24 paychecks each year.)
Contribution Rate: The contribution rate used in this calculation is based on the most recent QPP contribution rate on record for you. In general, your contribution rate depends on your tier status. If you are a Tier IV member, your rate also depends on your membership date and whether you participate in the Age 55 Retirement Program.
Interest Rate: For Tier IV members, the 5% interest included in the cost of the service credit purchase represents the annual interest that would have accrued on your pension contributions had you been contributing as a TRS member.
