If you work for the state of Washington as a teacher, a public employee, or a school employee, there is a good chance you are on what is called “Plan 2.” PERS 2, TRS 2, and SERS 2 all use the exact same formula, the exact same rules for cost-of-living raises, and the exact same penalties for retiring early. Once you understand one, you understand all three. In this post, we will walk through exactly how the Plan 2 pension works, step by step, with real numbers so you can see how it applies to your own paycheck.
What Is Plan 2, and Who Is On It?
Washington State runs three big retirement systems that share the same “Plan 2” rules: TRS 2 for teachers, PERS 2 for public employees, and SERS 2 for school employees like paraeducators, bus drivers, and office staff. If your paycheck comes from a public school district, a city, a county, or most state agencies, you are probably in one of these three plans. The good news is that once you learn the Plan 2 formula, it does not matter which of the three you are in. The math is identical.
Think of Plan 2 like a big, shared recipe. TRS, PERS, and SERS are just three different kitchens using the same recipe card. The ingredients (your years worked and your pay) are personal to you, but the recipe itself never changes between the three systems.
The Simple Formula Behind Your Plan 2 Pension
The Plan 2 formula has just two ingredients: how many years you worked, and your average pay during your five highest-earning years. In plain English, it’s 2% for every year you worked, multiplied by the average of your top five years of income. Pay attention to the word “top.” It is not your last five years, and it is not an average of your whole career. It’s whichever five years paid you the most, wherever they fall in your career.
That detail matters a lot for people who cut back their hours near the end of their career, or who took an administrative pay bump earlier on before moving back into the classroom. The state is going to hunt through your whole work history and use your five best years, not just whatever you were making right before you retired.
Let’s put real numbers on it. Say you worked 20 years in Washington State, and your average pay across your top five years was $100,000. Twenty years times 2% equals 40%. Forty percent of $100,000 is $40,000 per year, for the rest of your life once you retire. The table below lays out that same math so you can see how it changes with more years of service.
| Years Worked | Formula (Years × 2%) | Top 5-Year Average Pay | Annual Pension |
|---|---|---|---|
| 10 years | 20% | $80,000 | $16,000 |
| 20 years | 40% | $100,000 | $40,000 |
| 30 years | 60% | $100,000 | $60,000 |
| 35 years | 70% | $110,000 | $77,000 |
It does not matter how much money you personally put into the pension fund over the years. Whether you contributed $10,000 total or $100,000 total, your future benefit is decided entirely by this formula. Your contributions fund the plan, but they do not directly determine your check.
How Vesting Works
“Vesting” means you have worked long enough to lock in your right to a pension in the future. For Plan 2, that number is five years of full-time work. Once you hit five years, you are entitled to a pension check down the road, even if you quit tomorrow and never came back to Washington State employment.
Using our formula, five years of service equals 10% of your top five-year average pay. It will not be a huge check, but it is guaranteed once you are vested. Below five years, you have no pension entitlement at all if you leave state employment.
What You Pay Into the Plan
While you are working, a set percentage of your paycheck goes into the pension system automatically. Right now, that rate sits somewhere between 7% and 8%, though it is slightly different depending on whether you are in TRS, PERS, or SERS. The state reviews and adjusts these rates roughly every two years.
This is a mandatory, set amount. You cannot choose to put in more to boost your future pension, and you cannot put in less. Since your benefit is based purely on the years-and-pay formula, extra contributions would not increase your check anyway.
Ways to Increase Your Future Pension
You cannot change the 2% multiplier, but you have real control over the other two pieces of the formula: how long you work, and how much you earn. Working more years is the most obvious lever. The other lever, earning more, is broader than most people realize.
“Pay” for pension purposes is not just your base salary. It includes extra income like coaching stipends, national board certification pay, or advanced degree pay bumps. All of that gets added into your reportable income, which then raises your top five-year average and your eventual pension check.
A lot of people miss this detail: it does not matter which school district pays you for coaching. Even if you coach at a completely different district than where you teach, that pay still counts toward your pension, as long as it’s properly reported to the state. Mistakes happen here more often than you’d think. In one case, a coach’s stipend was never reported correctly, and fixing it added a couple hundred dollars a month to his eventual pension. It’s worth double-checking your own pay records for gaps like this.
The Little-Known Deferral Benefit
Plan 2 has a quirky feature that most members never hear about: a deferral benefit. If you leave state employment, say at age 55, but choose not to start collecting your pension right away and do not cancel your membership, your contribution balance grows by a guaranteed 5.5% interest rate for as long as you wait.
The catch: that 5.5% growth only matters if you’re planning to cash out your contributions entirely, which means forfeiting your future monthly pension for life. For most vested members, cashing out is a bad trade. Giving up a guaranteed lifetime income to collect a lump sum, even one growing at 5.5%, usually means losing far more money over a normal retirement than you gain. This deferral feature really only makes sense for someone who never vested in the first place and has no future pension to protect.
How Your Pension Adjusts for Inflation (COLA)
Once you retire and start collecting, your pension is eligible for an annual cost-of-living adjustment, or COLA. This adjustment can range from 0% to 3% each year, depending on inflation and what the state legislature approves. COLAs are applied once per year, on July 1st.
To qualify for a COLA, you must have been retired and collecting your pension for a full year already. One timing tip: if you retire shortly after July 1st, you could end up waiting almost two full years for your first cost-of-living increase. Timing your retirement date so it falls right before that July 1st cutoff can help you qualify for a COLA sooner.
When Can You Retire With Full Benefits?
Your full retirement age depends on when you were first hired. This is one of the most important rules in the entire Plan 2 system, so it gets its own table.
| Hire Date | Service Credit | Full Benefit Age |
|---|---|---|
| Before May 2013 | 30+ years | Age 62, no penalty |
| Before May 2013 | Fewer than 30 years | Age 65 |
| After May 2013 | Any amount | Age 65 |
In other words, if you were hired before May 2013 and built up 30 years of service credit, you can retire at 62 with your full, unreduced pension. Everyone else, regardless of how many years they have worked, has a full retirement age of 65. The one small break for newer hires: if you have at least three years of service credit, the state reduces (but does not eliminate) the penalty for retiring early.
The Real Cost of Retiring Early
Retiring before your full benefit age comes with a permanent reduction to your monthly check, and the size of that reduction depends heavily on your service credit. If you were hired before May 2013 and have 30 years of service credit, the penalty is fairly gentle: 2% off for the first year early, then 3% for every year after that. Retiring at 55, seven years early, would mean roughly a 20% permanent reduction.
Newer hires with 30 years of service credit face a flat 5% reduction for every year they retire before 65. That is steeper than the older schedule, but still manageable for someone with a long career.
The penalty gets much more severe for anyone without 30 years of service credit who wants to retire early, regardless of hire date. It starts around 8% to 9% for just the first year early and grows quickly from there. Someone in this group retiring at 55 might keep only about 30% of their full pension benefit. This is the single biggest reason to think carefully before retiring early if you have not hit that 30-year mark.
Choosing How Your Spouse Is Protected
When you retire, you also choose how your pension is paid out, and this choice affects your monthly amount. “Option 1” pays your full, unreduced benefit for your lifetime only, with nothing continuing to a spouse after you pass away.
The alternative is a survivorship option, where your spouse continues receiving a portion of your pension after you die: 100%, two-thirds, or half, depending on which option you select. Choosing survivorship always means a smaller monthly check while you are both alive, and the size of that reduction also depends on the age gap between you and your spouse. A bigger age gap (especially a younger spouse) means a bigger reduction, since the pension has to be spread over more expected years.
Why You Still Need to Save on Your Own
Plan 2 is a strong, dependable pension, but it has one real weakness: there is no cash value you can tap for emergencies. It pays you a steady paycheck for life, but if your water heater breaks or your car needs a new transmission, there is no lump sum sitting in the pension you can pull from.
That is exactly why most public employees in Washington also save through a supplemental account, like a 403(b) plan or the state’s Deferred Compensation Program (DCP), also known as a 457 plan. These accounts give you a pool of liquid savings that Plan 2 alone cannot provide, and starting one early gives you far more flexibility, including the option to retire earlier without leaning entirely on those early-retirement penalties we covered above.
Deciding between a 403(b), a DCP, or some mix of both depends on your personal situation: your current tax bracket, how close you are to retirement, and what other savings you already have.

Frequently Asked Questions
Is the Plan 2 formula the same for TRS, PERS, and SERS?
Yes. TRS 2, PERS 2, and SERS 2 all use the exact same formula: 2% times your years of service, times the average of your top five years of pay. The only differences between the three systems are small variations in the contribution rate you pay in while working.
How many years do I need to vest in Plan 2?
You need five years of full-time service to vest. Once vested, you are entitled to a pension in the future, even if you leave state employment and never return.
Can I retire at 62 under Plan 2?
Only if you were hired before May 2013 and have at least 30 years of service credit. Everyone else has a full retirement age of 65, though those with fewer years may retire earlier at a reduced benefit.
Does coaching pay count toward my pension?
Yes, coaching pay counts as reportable income for pension purposes, even if you coach at a different district than the one you teach in. Just make sure it is reported correctly to the state, since reporting errors can quietly shrink your future benefit.
Should I take the lump sum instead of my pension?
For most vested employees, no. Cashing out your contributions means giving up a guaranteed lifetime income, and the numbers usually favor keeping your pension intact rather than taking a lump sum, even with the 5.5% deferral interest rate applied.
Plan 2 is a solid foundation for retirement, but it works best when you understand exactly how the formula treats your years of service, your top five years of pay, and your chosen retirement age. Small decisions, like when you retire or how your coaching pay gets reported, can add up to real money over a lifetime of collecting.
