Washington DRS Calculator: How to Use It
Washington DRS covers multiple plan tiers. PERS 2 and TRS 2 are straightforward 2.0% DB plans. PERS 3 mixes a smaller DB with a DC account. The 2-year high average salary window is more favorable than most states.
What this calculator does
The Washington DRS Calculator applies the correct DB formula based on your plan: 2.0% per year for PERS 2 and TRS 2 members, or 1.0% per year for the PERS 3 defined benefit component. All plans use a 2-year high average salary. The calculator checks both unreduced retirement paths (age 65 with 5 years, or age 55 with 30 years) and calculates the 3%-per-year early reduction for members who retire from age 55 with 20 or more years but before reaching an unreduced threshold.
The COLA projection uses 2% compounding as a midpoint estimate within the 1-3% annual range. PERS 3 members should note that the DC component value is separate and depends on investment performance. The calculator covers the DB piece only.
What each input means
Plan selection
PERS 2 covers most state and local government employees. TRS 2 covers teachers and educational employees. PERS 3 is a hybrid option for PERS-covered employees who chose it at enrollment. If you're unsure which plan you're in, check your annual DRS statement. It identifies your plan on the first page.
Current age and years of DRS service
Your age today and your current credited service with Washington DRS. The calculator projects additional service from now to your planned retirement age. Decimals are accepted for partial years. Your annual DRS statement shows your credited service balance.
2-year high average salary
Washington DRS uses the average of your two highest consecutive years of salary. This is notably shorter than the 3-year or 5-year windows used in most other states. For members with strong final-year raises or promotions, the 2-year window captures those favorably. Enter the annual average of your two highest consecutive years, not just your current salary.
Planned retirement age
The minimum early retirement age is 55 with 20 or more years of service. The unreduced thresholds are age 65 with 5 or more years, or age 55 with 30 or more years. Retiring between 55 and 64 with 20-29 years triggers the 3% per year early reduction. Retiring at 55 with exactly 30 years is fully unreduced.
Understanding the outputs
The 2-year high average salary window is one of Washington DRS's most member-favorable features. On a salary path of $70,000 in year one and $73,000 in year two, the FAS is $71,500. Under a 3-year window that included a $67,000 year, the FAS would be $70,000, which is meaningfully lower. The 2-year window rewards members who had recent salary growth.
The early reduction of 3% per year before age 65 (for those with 20-29 years) is calculated from the number of years between your planned retirement age and 65. On a $3,000/month benefit, retiring 5 years early means a 15% permanent reduction: $450/month less, every month, for life. At 3% compounding COLA, that lost $450 grows in nominal terms every year, compounding the permanence of the early choice.
For PERS 3 members, the 1.0% DB formula produces a much smaller pension than PERS 2. A member with 25 years on a $72,000 2-year FAS earns $18,000/year from the PERS 3 DB formula, versus $36,000/year from PERS 2. The DC component is intended to compensate, but its value depends entirely on contributions and returns during the accumulation period.
The age 55/30-year path in practice
A state employee or teacher who starts at 25 and accumulates 30 years of DRS service by age 55 qualifies for a full unreduced pension at 55. On a $70,000 2-year FAS with 30 years, PERS 2 produces $42,000/year with no early reduction penalty. That's a compelling outcome for someone who enters public service young and stays.

Frequently asked questions
What is the difference between PERS 2, TRS 2, and PERS 3?
PERS 2 and TRS 2: 2.0%/year DB, 2-year high average salary. PERS 3: 1.0%/year DB plus DC account. PERS 2 and TRS 2 use the same formula and eligibility rules. PERS 3 was a hybrid option for PERS members who elected it.
How does the early retirement reduction work?
3% per year (0.25% per month) before age 65, for members with 20 or more years who retire between 55 and 64. Retiring at 60 with 20 or more years means 5 years early, producing a 15% permanent reduction.
What are the unreduced retirement paths?
Age 65 with 5 or more years, or age 55 with 30 or more years. Both qualify for a full unreduced benefit. The age 55/30-year path carries no early reduction penalty.
How does the COLA work?
1-3% annually, compounding, set each year by DRS. The calculator projects using 2% as a midpoint estimate. Over 20 years at 2%, your benefit grows to about 149% of the original nominal value.
How is the 2-year high average salary calculated?
Average of your two highest consecutive years of salary. This is shorter than most state pension windows. For members with recent salary growth, it captures that growth more favorably than a 3- or 5-year window would.
