SFERS Pension Calculator (San Francisco Tier 6)

SFERS Tier 6 applies to miscellaneous employees hired on or after January 7, 2012. The plan is a defined benefit pension, meaning your payout is based on a strict formula rather than investment performance. Before you can collect a benefit, you must meet specific age and service thresholds.

If you are unsure whether you have reached the minimum requirements to draw a benefit, you can use a pension eligibility calculator to map out your exact timeline based on your hire date.

Unlike some pension systems that apply a flat penalty for early retirement, SFERS Tier 6 uses a sliding scale for your benefit factor. The older you are when you retire, the higher the percentage of your salary you receive for every year you worked.

The benefit factor starts at 1.5% at age 50 and increases by 0.1% for every year you delay retirement, capping at 2.5% at age 60 and above.

Because the factor increases each year, working from age 55 to age 60 does more than just add five years of service to your calculation. It also increases the multiplier applied to all your previous years of service, resulting in a significantly larger monthly check.

The calculator applies the official SFERS Tier 6 formula to project your future income.

Annual Pension = Benefit Factor × Years of Service × Final Average Compensation

Where:

• Benefit Factor = The percentage assigned to your age at retirement (ranging from 1.5% at age 50 up to 2.5% at age 60+).
• Years of Service = Your total credited years working for the City and County of San Francisco.
• Final Average Compensation = The average of your highest 36 consecutive months of base pay.

Once you retire, your pension is protected against inflation, but the adjustment is calculated differently than Social Security. SFERS uses a "simple" Cost of Living Adjustment (COLA) capped at 2% per year.

Pension with COLA = Annual Pension + (Annual Pension × COLA Rate × Years Retired)

Where:

• Annual Pension = Your original base pension amount at the time of retirement.
• COLA Rate = The annual adjustment rate (maximum of 0.02).
• Years Retired = The number of years since your retirement date.

Because the COLA is simple rather than compound, the 2% increase is always based on your original retirement amount, not on the previous year's inflated amount. Over a 20- or 30-year retirement, this means your pension's purchasing power may gradually decline if actual inflation exceeds 2%.

Deciding when to leave city employment is the most impactful financial choice you will make. SFERS Tier 6 offers two distinct paths for defined benefit pension eligibility.

The Unreduced Path

You qualify for an unreduced benefit in two scenarios:

1. Age 65 with at least 5 years of service.
2. Age 55 with at least 30 years of service.

If you meet the 55/30 rule, you receive the 2.0% benefit factor for your age, but you are not penalized for retiring before age 65. Because you have 30 years of service, your pension will replace 60% of your Final Average Compensation (30 years × 2.0%).

The Early Retirement Path

You can retire as early as age 50 as long as you have 5 years of vested service. However, your benefit is permanently reduced because you are subject to the lower age-based benefit factors.

Scenario Example: Consider a city worker who has 20 years of service and a Final Average Compensation of $100,000.

• If they retire at age 50, their factor is 1.5%. Their pension is 1.5% × 20 years = 30%. They receive $30,000 per year.
• If they wait until age 60, they add 10 years of service (30 years total), and their factor jumps to 2.5%. Their pension is 2.5% × 30 years = 75%. They receive $75,000 per year (plus any salary growth that increased their FAC over that decade).

Delaying retirement in the SFERS system provides a massive financial advantage because you are simultaneously increasing your service years, your FAC, and your age multiplier.

Financial planners generally recommend replacing 70% to 80% of your pre-retirement income to maintain your standard of living. For most San Francisco city employees, the SFERS pension alone will not reach this threshold, especially if you retire before age 60 or have fewer than 30 years of service.

To close the gap, you will need to rely on supplemental income sources:

San Francisco Deferred Compensation Plan (SFDCP) The city offers a 457(b) plan, which functions similarly to a 401(k). Contributions can be made pre-tax or as Roth contributions. Because 457(b) plans do not have a 10% early withdrawal penalty if you separate from service before age 59½, they are the perfect bridge account if you plan to retire in your 50s. You can use a 457 plan withdrawal calculator to see how long your deferred comp savings will last.

Social Security Benefits As a San Francisco city employee, you pay into Social Security (unlike some California public employees who only pay into their pension system). This means you will receive both your SFERS pension and Social Security benefits. Deciding when to take Social Security (62 vs 67 vs 70) requires coordinating with your pension. Many retirees choose to claim their pension early and spend down their 457(b) assets while delaying Social Security to age 70 to maximize the guaranteed, inflation-adjusted payout.

Required Minimum Distributions (RMDs) If you hold pre-tax money in your SFDCP or traditional IRAs, you will eventually be forced to take taxable withdrawals starting at age 73. Because your pension already provides a high floor of taxable income, RMDs can push you into a much higher tax bracket later in retirement. Learning how to reduce taxes on Required Minimum Distributions through strategies like Roth conversions in your early 60s is critical for city retirees.

What is the SFERS Tier 6 plan?

Tier 6 is the defined benefit pension plan for San Francisco miscellaneous employees hired on or after January 7, 2012. It requires 5 years of service to vest, calculates benefits using your highest 36 consecutive months of pay, and scales the benefit multiplier based on your age at retirement (from 1.5% at age 50 to 2.5% at age 60+).

How is Final Average Compensation (FAC) calculated?

For Tier 6 members, your FAC is the average of your highest 36 consecutive months of compensation earnable. This typically consists of your base pay. Overtime pay and most irregular bonuses are generally excluded from the FAC calculation.

Is my SFERS pension taxable?

Yes. At the federal level, your SFERS pension is treated as ordinary income and is fully taxable. At the state level, California taxes all pension income. If you relocate in retirement, your tax burden will depend on your new state's laws. You can use a pension tax by state calculator to compare how moving might impact your net income.

What happens if I leave San Francisco city employment before retiring?

If you leave with fewer than 5 years of service, you are not vested. You must withdraw your own contributions (plus interest), but you forfeit the city's contributions and any right to a future pension. If you leave with 5 or more years of service, you are vested. You can leave your money in the system and claim a deferred retirement benefit once you reach age 50.

Can I collect Social Security and my SFERS pension?

Yes. San Francisco city employees contribute to Social Security. Because you paid Social Security taxes on your city earnings, your SFERS pension does not trigger the Windfall Elimination Provision (WEP), which reduces Social Security for public employees who did not pay into the federal system.

Does SFERS Tier 6 include survivor benefits?

Yes. If you are married or have a registered domestic partner at the time of retirement, you can choose a continuation option. You can elect to leave a percentage of your monthly pension (such as 50%, 75%, or 100%) to your surviving spouse after you die. Choosing a survivor benefit will permanently reduce the monthly amount you receive while you are alive.

What is the maximum pension I can receive under Tier 6?

For miscellaneous Tier 6 members, the maximum allowable pension benefit is capped at 75% of your Final Average Compensation. To reach this cap, you would need 30 years of service retiring at age 60+ (30 years × 2.5% = 75%).

Your SFERS pension is a powerful asset, but it is only one piece of your retirement puzzle. Once you have estimated your Tier 6 benefit, you should evaluate how your other accounts will generate income.

If you have built up a substantial balance in your SFDCP 457(b) or outside IRAs, use a retirement drawdown calculator to build a sustainable withdrawal strategy that bridges the gap between your pension and your actual living expenses. If you are considering leaving city service and want to understand the current worth of your earned benefits, a pension lump sum calculator can help you compare the value of your guaranteed monthly check against a theoretical cash buyout.
