Understanding the Municipal Employees’ Retirement System of Michigan (MERS) Defined Benefit Plan

Your future pension starts with a simple calculation tied to final average pay, service credit, and an employer-selected multiplier. These three parts work together to produce a steady, lifelong benefit that does not fluctuate with market returns.

Employers choose the exact multiplier that applies to your work group. To see that number for your account, log in at mymers.mersofmich.com and review your personalized details. The site also lists available plan options and key dates.

The framework is built for stability. Because benefits follow a formula, payout levels remain predictable even when investments swing. A full handbook is available to explain nuances and help you compare options before your retirement date.

Core components: final average compensation, service credit, employer multiplier.
Employer role: selects multiplier and specific plan options.
Member tools: online account and handbook to estimate benefits and plan a date.

Component	What it Means	Where to Find It	Why It Matters
Final Average Compensation	Average of highest earnings over set years	Account statements on portal	Drives base benefit amount
Service Credit	Total credited years and months	Service history in your profile	Multiplied to determine annual payout
Employer Multiplier	Percentage used in formula	Employer adoption note on portal	Directly affects benefit size

Governance and Fiduciary Responsibility

A dedicated board governs benefit policy and steers investment choices to protect long-term payouts.

The Retirement Board

The nine-member Retirement Board includes representatives from employer groups, staff, and retirees. They hold fiduciary duty for all assets and oversee the plan document daily.

The board sets policy, reviews costs, and ensures every pension payment is met. With an 80-year record, the system has never missed a scheduled payment, showing strong financial security.

Investment Strategy

The investment team runs a diversified portfolio and manages activity each business day. This hands-on approach helps preserve assets and support steady retirement income.

Inside MERS Investments offers deeper insight into how the fund balances risk, monitors performance, and keeps fees reasonable for participants.

Fiduciary oversight: active board review and cost control.
Investment focus: diversification, monitoring, and long-term growth.
Reliability: continuous payments backed by prudent asset management.

Area	Role	Impact
Board	Policy and fiduciary oversight	Protects participant benefits and cost controls
Investment Team	Daily portfolio management	Supports long-term fund performance
Governance	Fee monitoring and reporting	Maintains affordable plan costs and payment reliability

How the Defined Benefit Formula Works

A predictable, formula-driven approach turns work time and pay into a steady yearly benefit. The calculation centers on three clear parts that members can verify on their account.

Final Average Compensation

Final Average Compensation (FAC) uses your highest consecutive 36 or 60 months of earnings to create a base salary figure. This average is the first ingredient in the payout math.

Service credit counts every qualified month you earned. A typical standard is 10 eight-hour days per month, though some employers adopt 80 hours or another rule.

The annual payment equals: FAC × total service credit × employer multiplier. For example, 25 years of service with a 2% multiplier on a $35,000 FAC yields a $17,500 yearly benefit.

The FAC period (36 or 60 months) drives the base pay used in the formula.
Service credit reflects total qualified time, including any purchased credit.

Vesting Requirements and Service Credit

Vesting defines how much credited service you must earn before a future benefit becomes payable. Typical vesting options set by your employer require 10, eight, or six years of service credit to qualify for a mers defined benefit.

You can coordinate service credit from other MERS employers to help meet vesting rules, provided you have at least one year with each employer. The Reciprocal Retirement Act (Act 88) may also let you combine time from other Michigan governmental plans to qualify for a pension.

Keep contributions on deposit and watch gaps. A break in service longer than 20 years can block coordination. If you work for two employers in the same month, only one month of credit applies toward eligibility.

Check your account to track credits toward your final retirement date.
Contact the service center for help meet questions and personalized options.

Topic	Rule	Why it Matters
Vesting options	Usually 10, 8, or 6 years	Determines eligibility for a benefit
Credit coordination	One year minimum with each employer	Helps meet vesting and pension thresholds
Breaks in service	Over 20 years prevents coordination	Affects ability to use prior time

Managing Personal Contributions

What you contribute each pay period matters. Payroll deductions help your employer fund future payouts and keep the fund strong. You cannot change the required rate; the employer sets it for your group.

Additional deposits do not raise your formula-based benefit. Extra payments will not increase the final payout tied to your service and salary. Contributions are posted to your account and earn interest annually to grow your assets.

Each year you receive a statement showing total contributions and interest as of December. If you leave before your retirement date, you may request a refund of personal contributions. Doing so forfeits any future benefit under the arrangement.

Required contributions support long-term benefit security and plan funding.
Annual statements document growth and confirm posted interest.
Keeping contributions on deposit protects service credit and eligibility.

Topic	Rule	Impact	What to Check
Contribution Rate	Set by your employer	Determines payroll deduction amount	Review your payroll notice
Annual Statement	Issued every year (Dec snapshot)	Shows contributions and interest	Save for records and planning
Refund Option	Available if you leave before benefit date	Forfeits future benefit rights	Contact service center before deciding

Purchasing Additional Service Credit

Adding purchased service credit can shorten the wait for eligibility and grow your future benefit.

You can purchase extra service to help meet early retirement rules or to increase your monthly payment. Approval from your employer is required so the purchase aligns with your specific plan.

Other Governmental Service

If you worked for another agency and will not receive a benefit from that employer, you may buy that service credit. The cost depends on your age, projected earnings, benefit provisions, and your expected retirement date.

Generic Service Credit

You may purchase up to five years of generic service credit in total, including prior purchases with other employers. Military active duty may qualify for credit up to six years under special provisions.

You can use assets from other retirement plans — such as 457, 401, 403(b) accounts, or certain IRAs — to pay the cost.

Choice matters: purchasing time is a strategic choice that can increase your benefit and improve retirement security.

Designating Your Beneficiaries

A clear beneficiary designation removes uncertainty and speeds benefit delivery after your death. You can name three types: a refund beneficiary, a successor refund beneficiary, and a survivor beneficiary. Each type serves a different purpose for how your funds and future payments are handled.

Update any designation through the mymers.mersofmich.com portal. A survivor beneficiary must have an insurable interest in your life — for example, a spouse, child, sibling, parent, grandparent, or grandchild.

Trusts, estates, or other legal entities may be named as refund beneficiaries, but they cannot serve as survivor beneficiaries. If your spouse chooses to waive rights as a beneficiary, the waiver must be submitted in writing to be valid.

Review and update beneficiary information before your retirement date and after major life events.
To change a designation, complete the MERS Beneficiary Change Request Form 21 and submit it to the service center.
Keeping records current ensures your pension and related benefit options work as you intend.

Navigating Death Benefits for Active Employees

Clear rules govern what beneficiaries receive after an active employee dies, whether the event is duty-related or not. This short guide explains the main differences and what survivors should expect under the program.

Non-Duty Death

To trigger a lifetime payout, you must be vested. If vested, a surviving spouse receives the greater of 85% of the defined benefit formula or the elected survivor option.

If there is no spouse, unmarried children under 21 may share a portion of the benefit. If you are not vested and have no eligible survivors, your named beneficiary may request a refund of any employee contributions.

Duty Death

In a duty death, the spouse gets a minimum payment equal to 25% of your final average compensation, even if you were not vested.

Some employers adopt Program D-2. That option can add up to 10 years of service credit for duty death or duty disability and can increase the payout to better protect the family.

Key points: understanding death benefits supports your family’s financial security after your retirement date.
Active members’ beneficiaries may receive a lifetime pension payment or a refund, depending on vesting and survivors.
Contact your employer or the service center to confirm whether D-2 applies to your account and how to update beneficiaries.

Disability Retirement Provisions

If a medical condition ends your ability to work, disability benefits can provide steady income while you recover or adjust.

Disability retirement is available when an injury or illness prevents you from performing assigned duties. MERS reviews and must approve all claims so members receive the support allowed under their defined benefit plan.

There are two main types: non-duty disability and duty disability. Either type may be filed by you or by your employer. When your employer adopts the D-2 option, the allowance can include up to 10 extra years of service credit to boost the payment.

Purpose: maintain a stable income if you leave work before your planned retirement date.
Process: structured application and medical review to confirm eligibility and secure the benefit.
Support: your employer works with the service team to complete paperwork and verify service and salary records.

Type	Who Applies	Approval	Impact
Non-duty	Member or employer	Medical and administrative review	Stable monthly benefit based on service
Duty	Member or employer	Faster review when work-related	Possible higher payout and survivor protection
D-2 Enhancement	Employer adoption required	Applied at award	Adds up to 10 years service credit; raises pension

Preparing for Your Retirement Date

Before you set a date, check your account for the precise age and service credit needed to qualify. Eligibility depends on both factors and is shown in your online profile.

Early Retirement Options

Some members use the early reduced retirement option to begin payments sooner. This choice lowers the monthly amount but can match life plans and timing.

You must apply through the portal and pick a form of payment for your lifetime benefit. The site offers benefit estimate samples and tutorials that show how different selections affect your monthly pension.

“Reviewing estimates well before your date helps ensure service and salary records are accurate and avoids last-minute surprises.”

Regional teams are ready to answer questions and guide your application. Planning ahead makes it easier to balance employer-sponsored benefits, investment timing, and the payment option that best fits your life after work.

Generate a benefit estimate on myMERS to compare choices.
Consider early reduced retirement only after reviewing long-term impact.
Contact regional staff for hands-on help with the application and timelines.

Tax Implications and Cost of Living Adjustments

Managing withholding before your benefit date makes tax season easier when payments begin.

Most payouts are subject to federal and state income tax. You can set or change withholding through your account to match your expected tax liability.

Cost of Living Adjustments (COLA) may apply to help protect purchasing power. Not every group has the same COLA rules, so check your specific benefit options and effective date for any increase.

Annual statements and regular newsletters keep you informed about taxability, COLA changes, and investment reports. Tax forms and withholding guides are available on the portal to simplify year-end reporting.

Tax tip: review withholding well before your first payment to avoid surprises.
COLA role: periodic adjustments help benefits keep pace with inflation.
Investment focus: mers investments emphasize cost efficiency to support long-term plan security.

Item	Where to Find It	Why It Matters
Withholding settings	Account portal	Controls net payment and tax obligations
Annual statement	Mailbox and portal report	Documents payments, COLA, and tax info
Investment report	Website updates	Shows fund costs and long-term sustainability
