Speed up your progress to a more comfortable retirement without working extra years.

Purchasing service credit offers a powerful strategy for boosting your monthly pension payments for the rest of your life.

You could be eligible to increase your monthly retirement benefit amount by purchasing “airtime,” allowing you to buy one year of service credit for every five years of employment.1 If you’re vested by having 10 years of service and are an active, currently employed PERF or TRF Hybrid member, you may purchase additional service credit by meeting one or more of the following:

PERF

  • You have been in the fund for one year unless the purchased service is classified as “airtime.”
  • You worked in similar positions in another state.
  • You worked for a quasi-State agency before it became PERF/TRF-covered.
  • You have previous service from participating in the 1977 Fund or State Police Pension Trust and are not vested in that plan.
  • You have prior military service not credited under USERRA or other State pension law.

TRF

  • You have been in the fund for one year unless the purchased service is classified as “airtime.”
  • You worked in similar teaching positions in another state.
  • You worked in similar teaching positions in an accredited Indiana private school.2
  • You have substitute teacher service not included under membership eligibility, as outlined in the TRF Hybrid Member Handbook.
  • You have prior military service not credited under USERRA or other State pension law.

How much does it cost?

The purchase cost of additional service is calculated based on age, years of service, and salary. The calculation of the actual cost to purchase service credit is valid for 30 days. You have 30 days to sign the agreement and lock in the cost, and 90 days to pay in full. The price must be recalculated if the purchase is not completed in 30 days. The service credit must be purchased before separation and retirement.

If you’re interested in getting an estimate of how much it could cost you to purchase extra service credit, you can do one of the following:
