CalPERS Classic vs PEPRA — Side-by-Side

Same age, same years, same salary — different formula

Classic and PEPRA are two CalPERS membership classifications. Your hire date and prior CalPERS membership determine which one you fall under — you do not choose. PEPRA (the Public Employees' Pension Reform Act of 2013) applies to most members hired on or after January 1, 2013, while Classic applies to members hired before that date or with prior CalPERS service.

The differences that actually move your pension dollars: (1) Classic formulas hit their full benefit factor at an earlier age, so retiring in your mid-50s is far more valuable under a Classic formula. (2) Classic uses a 12-month final compensation average; PEPRA uses 36 months. (3) PEPRA caps the compensation that counts toward your pension. (4) PEPRA members pay a higher share of their own pension cost out of their paycheck.

Classic vs PEPRA at Reference Age — 25 Years, $8,000/Month Final Comp

Each row compares a Classic formula and its PEPRA counterpart, both evaluated at their own reference age. The dollar difference shown is per month — multiplied across a typical 20-year retirement, the lifetime gap is substantial.

The "Gap" column shows how much more a Classic member receives per month than a PEPRA member, both at their formula's reference age. Note that PEPRA reference ages are higher, so PEPRA members also wait longer for the full benefit factor.

Classic vs PEPRA — Frequently Asked Questions

Does the PEPRA salary cap affect my pension?▾
Yes, if your final compensation exceeds the cap. PEPRA limits the compensation used in the pension formula to a published annual cap that is adjusted yearly. Compensation above the cap does not increase your pension benefit, regardless of years of service. Classic formulas do not have this cap, though their compensation is subject to IRS Section 401(a)(17) limits.
Why does the benefit factor change every quarter year?▾
CalPERS publishes benefit factors at quarter-year intervals (e.g., 55.00, 55.25, 55.50, 55.75). This means your exact retirement date within a year affects your benefit factor. Retiring even three months later can increase your benefit factor and monthly pension.
What is the minimum retirement age?▾
The minimum retirement age varies by formula. Most PEPRA formulas allow retirement at age 52, while classic formulas may allow retirement as early as age 50. Your benefit factor at the minimum age is typically much lower than at the reference age.
What are the survivor benefit options?▾
CalPERS offers four retirement options: Unmodified (no survivor benefit, highest monthly payment), 100% Survivor (your beneficiary receives the same monthly benefit after your death), 75% Survivor, and 50% Survivor. Choosing a survivor option reduces your monthly pension. The reduction depends on your age and your beneficiary's age at retirement.
What is final compensation?▾
Final compensation is the average of your highest salary over a specific period, typically your highest 12 or 36 consecutive months depending on your formula. PEPRA members use a 36-month average; classic members typically use a 12-month average.
Which survivor option should I pick?▾
There is no single right answer — it depends on your beneficiary's age, your beneficiary's expected income without your pension, and your own life expectancy. The 100% survivor option costs roughly 12.25% of your monthly check but guarantees your beneficiary the same payment for life. The 50% survivor option costs roughly 6.5% and continues half. The unmodified option pays the most but ends at your death. Run all four side by side in the calculator's survivor selector.
