There are several factors used to determine your retirement benefit. First we consider your length of service. Then we calculate your high-five average salary, using your highest five years of salary.
We take these two pieces and apply it to a benefit multiplier, also known as a benefit formula, to determine your retirement benefit. The benefit formula is based a service-credit percentage and an aged-based factor.
SERVICE-CREDIT PERCENTAGE
Service years and months are converted to a percent of your average monthly salary.
- Years served started January 1, 1979 and after - you receive 2.5% for each year of service.
 - Years served before January 1, 1979 - you receive 5% for each year up to eight years and 2.5% for each year over eight years.
 
Example of how we calculate your benefit:
| 
			 The assumptions - first entered service 1/1/1985  | 
		|
| 
			 Age at retirement  | 
			
			 62  | 
		
| 
			 Allowable service  | 
			
			 12 years  | 
		
| 
			 Average monthly salary  | 
			
			 $3,083  | 
		
| 
			 The calculation  | 
		|
| 
			 12 years x 2.5% = 30% $3,083 (your average monthly salary) $925 computed monthly benefit* *Please note: if you decide to end your legislative career and apply for retirement benefits prior to age 62, an early-retirement reduction will apply.  | 
		
AGED-BASED FACTOR APPLIED
The computed benefit has an age-based factor applied, which was passed into law in 1997. This increases your benefit to compensate for slightly lower, future cost-of-living increases over your lifetime.
Example of how aged-based factor is applied:
| 
			 The assumptions  | 
		|
| 
			 Age at retirement  | 
			
			 62  | 
		
| 
			 Allowable service  | 
			
			 12 years  | 
		
| 
			 Average monthly salary  | 
			
			 $3,083  | 
		
| 
			 Computed monthly benefit  | 
			
			 $925 (calculated in above example)  | 
		
| 
			 Age-based factor  | 
			
			 9.0% (currently)  | 
		
| The calculation | |
| 
			 $925 x 8.7% = $80 $925 (your computed monthly benefit) $1,005 monthly benefit * * Please note: if you end your legislative career and apply for retirement benefits prior to age 62, an early-retirement reduction will apply.  |
