CalPERS Classic vs PEPRA: Which Tier Are You In?

How Your Tier Is Determined

Your CalPERS membership tier depends mainly on your membership date, with later employer changes, breaks in service, and qualifying reciprocity also affecting the classification.

Classic members generally entered membership before January 1, 2013, or qualify for the Classic enrollment level through reciprocity. They operate under the benefit formulas, final compensation rules, and compensation limits that existed before the California Public Employees' Pension Reform Act (PEPRA) took effect.

PEPRA members generally entered CalPERS membership on or after January 1, 2013, and do not qualify for the Classic enrollment level through prior membership in a reciprocal system. PEPRA established a new set of standardized rules with lower benefit formulas, stricter compensation averaging, and tighter caps.

Promotions or years of service alone do not change your classification. However, CalPERS may treat a member who joined before January 1, 2013, as a PEPRA new member when they join a different CalPERS employer after a break in service of more than six months; certain employer groups count as a single employer. Qualifying reciprocity can also affect enrollment level.

The Reciprocity Exception

There is one major exception. If you left a Classic-era position in one California public retirement system and were hired by a CalPERS employer after January 1, 2013, you may qualify for the Classic enrollment level through reciprocity. Generally, you must join the new reciprocal system within six months after leaving the prior system, with no overlapping service.

This matters for members who moved from CalSTRS to CalPERS, from a county '37 Act system to a state position, or between any qualifying reciprocal systems. If you think you may qualify, submit the Reciprocal Self-Certification Form (CalPERS-2593) to CalPERS and confirm your tier before making any retirement calculations.

Benefit Formula Differences

The most visible difference is the retirement benefit formula.

Classic Miscellaneous members have formulas set by their employer's contract with CalPERS. Common formulas include 2% at 55, 2% at 60, and 2.5% at 55. The percentage is the benefit factor at the target age, and it increases in quarterly increments until it caps.

PEPRA Miscellaneous members are on a standardized 2% at 62 formula. The factor starts at 1.000% at age 52 and increases quarterly to a maximum of 2.500% at age 67. No employer can contract for a higher formula for PEPRA members.

Classic Safety formulas vary — commonly 3% at 50 or 3% at 55. PEPRA Safety members are on 2.7% at 57, starting at 2.000% at age 50 and capping at 2.700% at age 57.

The practical effect: a Classic member on 2% at 55 can reach a 2% factor five to seven years earlier than a PEPRA member on 2% at 62.

Final Compensation Period

Classic members may have their final compensation calculated using either the highest single 12-consecutive-month period or the highest 36-consecutive-month period, depending on their employer's contract. The 12-month option is more favorable because a single strong year of pensionable earnings (including eligible special pay or a late-career raise) can set the entire final compensation figure.

PEPRA members must always use the highest 36-consecutive-month average. This smooths out spikes and generally produces a lower figure than a 12-month window would.

If you are Classic and unsure which period applies to you, check with your employer's HR department or look at your CalPERS Annual Member Statement.

Compensation Caps: 2025 and 2026

Both tiers have caps on pensionable compensation, but they are vastly different.

Classic members hired on or after July 1, 1996, are subject to the IRC Section 401(a)(17) limit. For 2025, the cap is $350,000. For 2026, it rises to $360,000. Classic members hired before July 1, 1996, are exempt from this cap entirely.

PEPRA members face much lower caps under Government Code Section 7522.10, indexed annually to CPI:

The "without Social Security" cap applies to members whose employer does not participate in Social Security — common among safety personnel and some local agencies. Once your pensionable compensation hits the cap during a calendar year, contributions stop for the rest of that year and earnings above the cap are excluded from your benefit calculation.

PEPRA Pay Exclusions

PEPRA also restricts what counts as pensionable compensation. Government Code Section 7522.34 excludes 13 categories of pay, including:

• Overtime and overtime allowances
• One-time bonuses not provided to all similarly situated employees
• Uniform, housing, automobile, and transportation allowances
• Cash-outs of unused vacation, annual leave, or personal leave
• Employer contributions to deferred compensation accounts
• Pay adjustments made in contemplation of retirement

Classic members generally have broader "compensation earnable" definitions that include more pay types. This means two employees in the same position earning the same gross pay can have different pensionable compensation figures depending on their tier.

Why the Distinction Matters for Your Retirement Planning

The tier you are in determines almost every number in your retirement estimate. Classic and PEPRA members with identical years of service, at the same age, in the same job, will receive different monthly pensions — sometimes substantially different.

If you are approaching retirement and are not certain of your tier, verify it before doing any benefit modeling. Log into myCalPERS and check your membership classification on your Annual Member Statement. If it says PEPRA and you believe you had qualifying reciprocal service, contact CalPERS to investigate before you file.
