Arizona ASRS Calculator: How to Use It
Three numbers drive an ASRS pension: credited service, the graded multiplier and average monthly compensation. Your membership date decides when it's unreduced and how big the early cut is.
What this calculator does
It adds your future service to your current service, applies the graded multiplier for that total, and multiplies by your average monthly compensation. Then it checks your retirement age against the normal retirement rules for your membership date. If you'd be early, it applies the reduction from A.R.S. 38-758 and shows what working to your earliest normal date would pay instead.
The result is the straight life annuity, the largest monthly option. Survivor options pay less.
What each input means
Membership date
Before or on/after July 1, 2011. It sets the AMC window (36 or 60 months), the normal retirement rules and the early reduction schedule.
Current age and planned retirement age
The calculator assumes you keep working until the planned age and start the pension then. Benefits can start at 50 at the earliest.
Years of ASRS credited service
Contributing service plus any service you've bought, from your myASRS account. Fractions count, and the multiplier steps up at exactly 20, 25 and 30 years.
Average monthly compensation
A monthly figure, not annual. Use your highest 36 or 60 consecutive months within your last 120 months, depending on your membership date.
Understanding the outputs
Green means a normal retirement with no cut. Yellow means early, with the permanent reduction shown. Red means you can't draw a pension at that age yet, either because you're under 50 or because you have under 5 years and haven't reached 65.
Lifetime totals assume no Permanent Benefit Increases, since they depend on investment returns and aren't available to newer members.
The early reduction, worked through
Post-2011 member, 57 with 22 years: counted back from 62, that's 2 years at 3% plus 3 years at 5% = 21%. Pre-2011 member, same age and service: 79 points, so the cut is the smaller of 3% (one point short) and 15% (3 years under 60 at 5%). That member gets 3%.

Frequently asked questions
Which membership date should I pick?
The date you first became an ASRS member. Before July 1, 2011 means a 36-month AMC and the 80-point rule. On or after July 1, 2011 means a 60-month AMC and fixed age-and-service combinations instead of points.
What is the graded multiplier?
2.10% with under 20 years, 2.15% with 20 to 24.99, 2.20% with 25 to 29.99 and 2.30% with 30 or more. The rate for your total service applies to all of your years.
How is the early reduction figured?
5% a year from 50 to 60 and 3% a year from 60 to 65, counted back from your reference age: 62 with 10+ years or 65 with 5 to 9.99 for post-2011 members; 60, 62 or 65 for pre-2011 members by service. Pre-2011 members with 77 to 79.99 points can instead lose 3% per point short of 80 if that's smaller.
Does the calculator include the Permanent Benefit Increase?
No. The PBI is paid only in years when investment returns beat 8%, is split by years of service, and isn't available to members who joined on or after September 13, 2013. The calculator assumes no increases.
Is there a maximum benefit?
Arizona statute doesn't cap the benefit at a percentage of AMC.
