How the Montana TRS formula works
Montana TRS uses a 1.6667% multiplier (one-sixtieth) on your average final compensation. Tier Two members, hired on or after July 1, 2013, use the average of their highest five years and reach full retirement at age 60 with five years or under the Rule of 90.
This calculator uses a single percentage and a simplified formula, so treat the result as an estimate and confirm your figure with TRS. Montana teachers also pay into Social Security.

Questions
How is a Montana TRS pension calculated?
The TRS benefit multiplies a 1.67% multiplier by your average final compensation by your years of service. For example, 30 years at a $50,000 average final compensation is 1.67% × $50,000 × 30 = $25,050 per year before any early-retirement reduction.
What multiplier does Montana TRS use?
It is 1.67% per year of service. Adjust the percentage on the calculator if your tier or service level uses a different rate.
Do Montana teachers get Social Security?
Yes. Montana teachers pay into Social Security, so most receive a TRS benefit plus a Social Security benefit. Adding any 403(b) or 457(b) savings completes the picture.
