Two interest rates are used to calculate service purchases.
Buyback interest is 4.125%.
Actuarial assumed interest if 8.25%.
Interest is compounded annually on service purchases.
Chapter 176 of the Acts of 2011 amended the interest rate used to calculate purchases of creditable service that are defined under MGL Chapter 32, s.3.
- An individual who became a member prior to April 2, 2012 has until April 2, 2013 to apply for and enter into a payment agreement to qualify for buyback interest (4.125%). If the individual defaults on any payment plan, actuarial assumed interest (8.25%) will be charged on any balance.
- An individual who returns to service after April 2, 2012, has until April 2, 2013 or one (1) year from the date of re-entry, whichever is later to apply for and enter into a payment agreement to qualify for buyback interest (4.125%). If the individual defaults on any payment plan, actuarial assumed interest (8.25%) will be charged on any balance.
- An individual who first becomes a member after April 2, 2013 is subject to actuarial assumed interest (8.25%) on all service purchases which fall under MGL Chapter 32, s.3.
