PERSI Retirement Rules: How to Plan for a Secure and Comfortable Retirement

Admin • January 5, 2024

The Public Employee Retirement System of Idaho (PERSI) is a retirement plan for public employees of Idaho, made up of members from over 850 employer organizations across the state. The $22 billion plan offers retirement, disability, and death benefit programs to over 177,000 members. In 2022, over $1 billion in benefits were paid to PERSI retirees living in Idaho, with an average monthly benefit of $1,800. 

Whether you’re a new public employee just entering PERSI, or you’re nearing retirement and thinking about your future, understanding PERSI’s retirement rules can help you in your retirement planning. Having a comprehensive plan that includes your PERSI benefits can lay the foundation for a secure and comfortable retirement in your golden years. 

Understanding PERSI Basics

PERSI was founded in 1963 as a defined benefit retirement plan to offer a measure of retirement security for Idaho’s public employees. Through the plan, retirees receive a fixed monthly pension based on factors including years of service and salary. 

During its first 35 years, PERSI’s plan was a traditional defined benefit plan, now known as the PERSI Base Plan ; in 2001, PERSI added a defined contribution plan, called the PERSI Choice 401(k) Plan , to supplement the Base Plan. 

  • Base Plan : Enrollment in the defined benefit Base Plan is automatic, and once vested, you’ll receive a lifetime benefit at retirement. Both you and your employer make contributions to the Base Plan, which are invested and grow over time. Your contributions go into your personal account, while employer contributions are pooled in a trust fund to cover future benefits for all members. 

For 2023, as a general member, you contribute 6.71% of your annual salary to the Base Plan, and your employer contributes 11.18%. This percentage varies if you are a public safety member or a school employee member, and it will increase for all members in 2024. Retiring as a vested member means you’ll receive a fixed monthly payment for the rest of your life.

  • Choice 401(k) Plan : Participation in the defined contribution Choice 401(k) Plan is voluntary, unlike the Base Plan. The Choice 401(k) Plan allows you to contribute a portion of your salary, pre-tax, via payroll deductions. You can direct your investments among several investment options. The amount available in your Choice 401(k) at retirement is dependent on your contributions and the performance of your investments.

The combination of these two plans from PERSI offers an optimal blend – the security of the Base Plan, and the opportunity for self-directed investments and voluntary contributions in the Choice 401(k) Plan.

PERSI Eligibility and Retirement Rules

Understanding how to join PERSI and what it means for your retirement is paramount for utilizing this helpful benefit and resource. 

Joining PERSI

When you work in an eligible position for one of over 850 PERSI employers, you become a PERSI member. As an eligible employee, you accrue service credit for each month you work; the credited service is used to calculate your PERSI benefit at retirement. You’ll earn one month of service for each calendar month worked, with at least 20 hours worked during a week. You won’t earn additional service credit by working overtime.

Once you’ve earned 60 months of service credit, you’ll be considered vested and receive a lifetime benefit at retirement. The five-month vesting period doesn’t need to be with the same PERSI employer – you can change public service jobs without impacting your PERSI membership.

Planning for Retirement

To receive your full PERSI retirement benefits, you must reach your service retirement age; or, you must meet the minimum age requirement when you retire, have at least 60 months of credited service, and you also must meet the Rule of 80/90 . These requirements differ if you are a general member, or public safety member – police officer or firefighter.

The Rule of 80/90 = your age + your years of service = 80/90 (or more)

For general members, you must be at least 55 years old and meet the Rule of 90. For police officers or firefighters, you must be 50 years old and meet the Rule of 80. For members with mixed service, your requirements depend on your ratio of general and police-firefighter service –  you’ll have to be between 50-55 years old and meet a Rule of 80 or 90, with both depending on your ratio.

If you retire before reaching your service retirement age (65 years old for general members, 60 years old for police and firefighters), or before reaching the Rule of 80/90, your retirement benefit will be reduced.

If you decide to work beyond your service retirement age or the Rule of 80/90, your retirement benefit will continue to increase.

Calculating Your PERSI Retirement Benefits

Determining the amount of your PERSI retirement benefits and how much income you’ll receive can help you better plan for retirement. PERSI benefits are calculated using a straightforward formula involving your average monthly salary during a Base Period (currently 42 months), a multiplier of 2% for general members or 2.3% for police officers and firefighters, and your months of service.

Average Monthly Salary during Base Period  x Multiplier x Months of Service

For example, if you’re a general member, your average monthly salary is $3,000, and you have 360 months of service:

$3000 x 2% x 360 months = $21,600 

÷ 12 months = 

Monthly benefit of $1,800

The value of your PERSI benefits typically far exceeds your contributions – within the first 3-5 years of retirement, most PERSI members have received a return greater than the money they contributed while working. And you’ll continue to receive your benefits payment for the rest of your life. PERSI also considers cost-of-living adjustments (COLAs) to Base Plan benefit payments annually. Your PERSI benefits are a guaranteed, long-term source of retirement income – something very difficult to find in another investment.

Planning for Retirement with PERSI

There are several retirement distribution options available for PERSI members to choose from. The Regular Retirement option provides the largest benefit, with full payment throughout your life, but it has no Contingent Annuitant (CA) protection for your spouse or dependents. PERSI offers two CA Allowance retirement distribution options with either 100% or 50% CA allowances, as well as a Social Security Adjustment option and two options that are a CA/Social Security blend.

If you’re planning on retiring in the next few years, or even if you’re years away from retirement, knowing how the PERSI retirement process works can help make it more efficient and seamless. PERSI provides a helpful retirement checklist to follow throughout your career as a guide.

Comprehensive Retirement Planning

A comprehensive retirement plan that includes income and investments beyond your PERSI Base Plan and Choice 401(k) Plan will offer you more opportunities to save for retirement and reach your financial objectives. Your goals for retirement are based on your unique situation, and working with a financial advisor can help you create a retirement plan that is customized to your individual circumstances, risk tolerance, timeline, and objectives.

How to Build a Retirement Plan That Works No Matter What the Economy Does

August 14, 2025
We’re all feeling it these days: the underlying feeling of uncertainty about what lies ahead. Each day, we see headlines about inflation, Social Security’s future, or market swings. Unsurprisingly, Gallup tells us that the top three American fears have to do with money: the economy, availability/affordability of healthcare, and inflation. If you’re in your 50s and 60s, these concerns probably hit even closer to home. You’re not just thinking about the economy in general terms. You’re wondering how it will affect your specific retirement plans. Your mind likely turns to: Increasing healthcare costs – can you absorb unexpected costs on a fixed income? Inflation and market volatility – will the value of the dollar diminish your retirement savings? Social Security uncertainty – will it exist when you retire? Having enough saved – will your retirement budget hold up when the time comes? About 1 in 4 Americans over 50 are delaying retirement , and it’s not hard to understand why. With thoughtful planning and the right strategies, you can build confidence in your ability to maintain your lifestyle on a fixed income, regardless of what economic curveballs come your way. 5 Key Strategies to Prepare for Living on a Fixed Income Uncertainty doesn’t have to derail your retirement plans. By addressing these five critical areas, you can build a foundation that allows you to enjoy the retirement you’ve worked toward. 1. Review (And Potentially Adjust) Your Retirement Timeline One of the most powerful tools you have is flexibility with your retirement timeline. While certain ages qualify you for benefits or withdrawals from certain accounts, there’s no concrete age you have to retire at. Traditional retirement at 62 or 65 might not make sense for your unique situation; you should feel free to alter your timeline to make sense for you and your family. Consider Your Social Security Strategy Your Social Security benefits increase each year you delay claiming them beyond your full retirement age, up until age 70. For many people, this creates a meaningful boost to their guaranteed monthly income. If you can afford to wait, this strategy alone can significantly strengthen your fixed-income foundation. Explore Phased Retirement Options Rather than going from full-time work to complete retirement overnight, consider a gradual or phased transition. Many of our clients find success with: Part-time consulting in their field of expertise Freelance work that leverages their skills Small business ventures they've always wanted to try Investment properties that generate passive income This approach not only eases the financial transition but often provides a sense of purpose and engagement during early retirement. 2. Fine-Tune Your Investment Mix and Retirement Income Strategy Adjusting your portfolio is an ongoing responsibility, not a one-time task before retirement. Continue to revisit and rebalance as a proactive part of your retirement plan. Equally important is creating multiple income streams to reduce your reliance on any single source. Diversify Your Retirement Income Sources Think of building several income bridges instead of relying on one massive one. Your retirement income might come from Social Security, traditional retirement accounts (401(k), IRA), Roth accounts for tax-free withdrawals, and taxable investment accounts for flexibility. Each serves a different purpose in your overall strategy. Is Your Portfolio Inflation-Resistant? Cash can feel safe, but inflation quietly erodes its purchasing power over time. If you want an honest look at the hard numbers of inflation, see the Bureau of Labor Statistics CPI Inflation Calculator . For example, we see that $1,000,000 in 2015 has the buying power of $1,380,194 in 2025. You would need an extra (almost) $380,000 to make up for inflation. Inflation is a reality of the economy that everyone deals with, but your investment strategies can mitigate its impact on your net worth. Consider allocating a portion of your portfolio to assets that historically perform well during inflationary periods. Don’t Abandon Growth Too Soon If you're retiring in your early 60s, you could have 20-30 years ahead of you. Being overly conservative with your investments might feel safer in the short term, but it could leave you struggling to maintain your lifestyle later. A balanced approach that includes growth-oriented investments can help ensure your money lasts as long as you do. 3. Reduce Outstanding Debts The Federal Reserve’s most recent Survey of Consumer Finances reports that the average older adult (ages 65 and up) carries between $95,000 and $172,000 in debt. The bulk of those debts is from outstanding mortgage balances, but credit card and medical debts contribute significantly. Prioritize Your Debt Payoff Strategy High-interest debts from credit cards and personal loans can take up a lot of room on a fixed income. Consider whether it makes sense to use some of your current higher income to aggressively pay down these balances before you retire. There are two primary ways of tackling multiple debts: Avalanche: Pay off your balances starting with the highest interest rates. Snowball: Pay off your balances from smallest to largest. Entering retirement debt-free can be a very freeing experience. Consider Your Mortgage Your mortgage situation is more nuanced. Some retirees find comfort in owning their home outright, while others benefit from maintaining their mortgage if it's at a low interest rate, and money can be invested for higher returns. The right choice depends on your specific situation and comfort level. 4. Plan for Healthcare Costs and Insurance Transitions Healthcare expenses are frequently retirees' most underestimated cost. Add in Medicare's maze of coverage options, and it's no wonder many retirees feel unprepared. Planning for these expenses and understanding your options before you need them can prevent costly surprises that strain your fixed income. Understand Your Medicare Options If you're 65 or older: Enroll in Medicare during your Initial Enrollment Period (IEP), which begins 3 months before your 65th birthday and extends 3 months after Consider supplemental coverage options: Medigap (if you choose Original Medicare Parts A and B) Medicare Advantage (Part C) as an alternative to Original Medicare Prescription Drug Coverage (Part D), if not included in your plan If you’re under 65 and retiring, consider: COBRA coverage from your employer allows you to keep your current plan for up to 18 months, but you'll pay the full premium plus administrative fees (typically $400-$700 per person monthly) Your spouse's employer plan (if available and you're eligible) An Affordable Care Act (ACA) marketplace plan Prepare for the end of employer-sponsored insurance coverage about a year in advance to avoid lapses in coverage. Build a Healthcare Reserve According to the 2025 Fidelity Retiree Health Care Cost Estimate , a 65-year-old individual may require approximately $172,500 in after-tax savings to cover health care expenses in retirement. Consider establishing a separate savings account specifically for medical expenses. Health Savings Accounts (HSAs), if you're eligible, offer triple tax advantages and can be particularly valuable for retirement healthcare planning. 5. Create a Flexible Retirement Budget It’s wise to reevaluate where your money is going every month so you can enjoy once-in-a-lifetime retirement opportunities fully. This, combined with an emergency fund, helps avoid lifestyle creep and the stress of unexpected expenses. Plan for the “Retirement Smile” Retirement spending tends to move in a “U” shape: higher spending in early retirement, less in the middle, and back up again towards the end. While your bucket list trips and experiences are significant expenses, they’re often one-and-done. Most people do these things early on in retirement and slow down into a more predictable financial rhythm. Towards the end of retirement, costs often increase again to cover long-term care needs. Organize Your Budget Into Categories Consider dividing your retirement expenses into essential costs (housing, utilities, healthcare), lifestyle expenses (travel, dining, hobbies), and discretionary spending (gifts, major purchases). Cover your essentials with your most reliable income sources like Social Security, while funding lifestyle expenses through portfolio withdrawals that can adjust during market downturns. How Can You Reduce Your Future Cost-of-Living? Consider ways you can capitalize on your existing assets to better position yourself for the future. If you’ve built significant home equity, downsizing or moving to a more affordable city may be a great option, as you’ll benefit from liquidity and reduced costs. Rely on A Trusted Fiduciary Financial Planner If you’re feeling anxious about the future, know this: you’re not stuck doing it on your own. With the help of a fiduciary financial planner, you can not only see if your plan holds up against inflation and economic uncertainties, but they will:  Prioritize tax-efficient retirement withdrawal strategies Strategize Required Minimum Distributions (RMDs) Create a sustainable withdrawal strategy The best thing you can do for a healthy retirement is to leverage the experts.

40 and Catching Up: Why This Decade Could Be Your Best for Building Wealth

July 18, 2025
Your 40s arrive with a unique mix of clarity and urgency. You've likely figured out what you want from life, but suddenly retirement no longer feels like a distant concept. If you're looking at your financial situation and feeling behind, you're not alone. Many people in their 40s experience this same wake-up call. The good news is that this decade offers some of the most powerful opportunities to accelerate your wealth-building journey. Think of your 40s as your financial prime time. You're earning more than you ever have, you understand money better than in your 20s and 30s, and you still have 20-25 years to let compound growth work its magic. Instead of dwelling on what you should have done differently, let's focus on what you can do right now to make this decade count. The Reality Check: Where You Stand vs. Where You Want to Be Before exploring strategies, let's acknowledge the elephant in the room. Many financial experts recommend saving three times your annual salary by age 40. If you're reading this and thinking, "I'm nowhere near that," take a deep breath. Life happens. Maybe you started your career later, switched fields, dealt with medical expenses, helped family members, or simply prioritized other goals during your 30s. The key is to start from where you are today, not where you think you should be. Your 40s bring unique advantages: higher earning potential, greater financial discipline, and often more stable life circumstances. Many successful investors didn't hit their stride until their 40s or later. You're not behind; you're just getting started on a more intentional path. Retirement Savings Strategies That Work in Your 40s Your retirement savings strategy in your 40s should differ from someone in their 20s or 30s. You have less time but more resources, which means you need to be both aggressive and smart about your approach. First, maximize your employer's 401(k) match if you haven't already. This is free money, and missing out on it is like leaving cash on the table. Additionally, consider increasing your contribution rate by 1-2% each year, or whenever you receive a raise. This gradual approach makes the adjustment less painful while significantly boosting your long-term savings. Roth conversions become particularly powerful in your 40s. If you expect to be in a higher tax bracket in retirement or if you want to leave tax-free money to heirs, converting some traditional IRA or 401(k) funds to Roth accounts can be a smart move. The key is to do this strategically, perhaps in years when your income is temporarily lower or when you can manage the tax impact. Don't overlook the power of diversification beyond your 401(k). A taxable investment account gives you flexibility and access to your money before age 59½ without penalties. This can be crucial for achieving early retirement goals or covering major expenses that may arise before the traditional retirement age. Catch-Up Retirement Contributions: Start the Habit Now Once you reach 50, you can make catch-up contributions to your retirement accounts, which significantly increases your savings potential. For 2025, this means an additional $7,500 in 401(k) contributions (bringing your total to $31,000). However, you don't have to wait until 50 to think like someone making catch-up contributions. Start now by treating your savings rate as if you're already eligible for these higher limits. If you can save an extra $600 per month ($7,200 annually) starting at 45, you'll have built the habit by the time you're actually eligible for catch-up contributions. Retirement Milestones by Age 40: A New Perspective Traditional retirement milestones can be discouraging if you're starting later or if life hasn’t gone as planned. Instead of focusing on arbitrary multiples of your salary, consider these more practical benchmarks for your 40s: The Emergency Fund Foundation : Before aggressively pursuing retirement savings, ensure you have a solid emergency fund in place. This prevents you from having to tap retirement accounts during tough times. Aim for 3-6 months of expenses, adjusted for your specific situation. The Debt Freedom Focus : High-interest debt can quickly derail retirement plans. If you're carrying credit card debt or other high-interest obligations, addressing these might be more valuable than maximizing retirement contributions beyond your employer match. The Income Replacement Goal : Rather than focusing on net worth multiples, think about what percentage of your current income you're on track to replace in retirement. A good target is 70-80% of your pre-retirement income, but this depends on your lifestyle and retirement plans. The Flexibility Buffer : Your 40s are a great time to build financial flexibility. This means having investments outside of retirement accounts that you can access without penalties, creating multiple income streams, and maintaining career skills that keep you marketable. Insurance: Life and disability insurance coverage should reflect your current income and family needs. Estate Planning : A basic will, power of attorney, and healthcare directive should be in place. Making Your Peak Earning Years Count Your 40s often represent your peak earning years, and how you manage this increased income will significantly impact your financial future. The temptation to inflate your lifestyle with every raise is real, but this decade calls for more strategic thinking. Consider implementing a "pay yourself first" approach where you immediately redirect any income increases to savings and investments. If you get a $5,000 raise, automatically increase your 401(k) contribution by $3,000 and your taxable investment account by $2,000. You'll barely notice the difference in your take-home pay, but you will thank yourself in the future. This is also the time to think seriously about additional income streams. Whether it's consulting in your field, starting a side business, or investing in rental real estate, diversifying your income sources provides security and potential for acceleration. Building Wealth Beyond Retirement Accounts While retirement accounts are crucial, they shouldn't be your only wealth-building tool. Your 40s are an excellent time to diversify your investment approach and build wealth that's accessible before traditional retirement age. Consider opening a taxable investment account if you haven't already done so. This provides flexibility and liquidity while still offering growth potential. Focus on tax-efficient investments, such as index funds, and consider holding dividend-paying stocks or REITs for their income potential. Real estate can be particularly powerful in your 40s. Whether it's paying off your primary residence early, investing in rental properties, or exploring REITs, real estate adds diversification and potential inflation protection to your portfolio. Don’t Forget the “You” Factor We’d be remiss not to mention this: life in your 40s is busy. You might be managing aging parents, teenagers, or a toddler (or all three). You may be helping your partner through a career change or navigating one yourself. It’s a lot. Which is precisely why intentional financial planning matters now more than ever. You don’t need to do it perfectly. You just need a plan that’s rooted in your real life — your values, your vision, and your goals. A good financial advisor can help you prioritize, simplify, and clarify the next best steps, even if you feel like you’ve fallen behind. Ready to Create Your Personal Financial Strategy?
