The public employees retirement association of colorado (PERA) is the retirement system serving over 600,000 current and former public employees across the state of Colorado. According to PERA's own published data, the system manages approximately $60 billion in assets, making it one of the largest public pension funds in the Rocky Mountain region.
Yet many members struggle to understand their benefits, navigate the complex tier system, or plan confidently for retirement.
This article breaks down the essential facts about the public employees retirement association of colorado, including how membership tiers affect your benefits, what the funding status means for your pension security, how to access your account, and the most common mistakes members make when planning their retirement.
What Is the Public Employees Retirement Association of Colorado?
The public employees retirement association of colorado is a defined benefit pension plan established in 1931 to provide retirement security for Colorado's public workforce. Unlike a 401(k), where your retirement income depends on investment returns, PERA promises a specific monthly benefit based on a formula.
Who Belongs to PERA?
PERA covers employees from over 500 government agencies, including:
- State government workers
- Public school teachers and staff
- Employees of many cities, counties, and special districts
- Judges and judicial staff
- State troopers and other public safety workers
The system operates through five divisions: State, School, Local Government, Judicial, and Denver Public Schools. Each division has slightly different contribution rates and benefit structures.
How Membership Works
When you start a covered job, you and your employer both contribute a percentage of your salary to PERA. These contributions fund the retirement pool that pays benefits to current retirees.
How to apply this: Log in to your PERA account and confirm which division and membership tier you fall under, since this determines your contribution rate and benefit formula.
Funding Status: What the Numbers Mean for Your Pension
The financial health of the public employees retirement association of colorado directly affects benefit security. PERA publishes an annual Comprehensive Annual Financial Report (CAFR) that details its funding ratio — the percentage of promised benefits backed by current assets.

Understanding the Funding Ratio
A funding ratio below 100% means the system has an unfunded liability. PERA's board and the Colorado legislature have taken steps to address this through reforms. Senate Bill 18-200, passed in 2018, increased member and employer contributions while adjusting benefits for future retirees.
The Colorado PERA Board of Trustees states that "the plan is designed to achieve full funding over a specified amortization period, with adjustments triggered if funding falls off track." This automatic adjustment mechanism, known as the "guardrail" provision, is a unique feature of PERA's reform framework.
What This Means for You
Your pension benefit is protected by Colorado law. The Colorado Supreme Court has ruled that PERA benefits earned under existing contracts cannot be substantially impaired. However, future benefit accruals can be adjusted by legislation.
How to apply this: Review PERA's latest CAFR funding summary on their website to understand where the system stands and what automatic adjustments, if any, are scheduled.
PERA Membership Tiers: Why Your Hire Date Matters
The public employees retirement association of colorado uses a tiered system based on your date of hire. This is one of the most important factors affecting your retirement benefit.
| Tier | Hire Date Range | Key Difference | Action to Take |
|---|---|---|---|
| Pre-2007 | Before January 1, 2007 | Most generous benefit formula, earlier full retirement | Verify your tier on your annual statement |
| Tier 1 | 2007 – 2010 | Slightly reduced benefits, higher age requirements | Calculate projected benefit under current formula |
| Tier 2 | 2011 – 2019 | Higher contribution rates, later retirement age | Consider supplemental savings to bridge gap |
| Post-2019 | After January 1, 2020 | Latest adjustments under SB 18-200 | Review your projected benefit annually |
Each tier has different rules for:
- Normal retirement age
- Benefit multiplier (the percentage of salary you receive per year of service)
- Highest average salary calculation
- Cost-of-living adjustment (COLA) eligibility
How to apply this: Find your hire date, identify your tier, then use PERA's online benefit calculator to estimate your monthly retirement income under your tier's specific formula.
Accessing Your PERA Account and Managing Benefits
The public employees retirement association of colorado provides online tools that most members underutilize. Your PERA account portal gives you access to contribution history, service credit, and benefit estimates.
Key Online Resources
PERA offers several tools through its official website:

- Member Account Portal — view contributions, service credit, and beneficiary designations
- Benefit Estimate Calculator — project your retirement income under different scenarios
- PERA's Retirement Planning Guide — detailed documentation of all benefit rules
You can access these through the Colorado PERA website. Additionally, PERA hosts educational webinars and one-on-one counseling sessions.
Monitoring Your Account
Check your account at least annually for accuracy. Verify that your employer is reporting your salary and service correctly. Errors caught early are much easier to fix than errors discovered at retirement.
How to apply this: Log in to your account this week, verify your service credit matches your employment history, and update your beneficiary designation if your life circumstances have changed.
Common Mistakes Members Make with the Public Employees Retirement Association of Colorado
Understanding the public employees retirement association of colorado rules helps you avoid costly errors. PERA's member education team reports that many members misunderstand key provisions.
Mistake 1: Assuming You'll Receive Full Social Security
Many PERA members do not pay into Social Security through their PERA-covered employment. This means your PERA pension may be your primary retirement income. The Windfall Elimination Provision (WEP) and Government Pension Offset (GPO) may also reduce any Social Security benefits you earned from other jobs.
Mistake 2: Retiring Without Understanding the COLA
PERA's annual increase (COLA) is not guaranteed at a fixed rate. It depends on the division's funding status and is calculated annually. Assuming a 3% annual increase when the actual COLA may be lower can significantly impact your long-term retirement income planning.
Mistake 3: Overlooking the PERAPlus 401(k) and 457 Plans
The public employees retirement association of colorado offers voluntary supplemental savings plans. Many members miss the opportunity to save additional pre-tax dollars beyond their mandatory pension contribution.
How to apply this: Review your Social Security statement to see whether you have WEP-affected benefits, and consider opening a PERAPlus account for supplemental retirement savings.
