If you work under FERS and are planning your retirement, you have three pieces to line up: a pension, a supplement, and a TSP. Your date, your survivor election, and your withdrawal order can each affect your income for years. Some of those choices are hard to undo once you file.
Before you retire, the work of FERS retirement planning comes down to a handful of decisions that interact, and getting their order wrong can cost you income you cannot recover. Federal benefits look simple on a benefits statement. In practice, the pension, the supplement, and the Thrift Savings Plan answer to different rules, different ages, and different tax treatment. This guide walks federal employees through the choices that matter, and shows where a quiet mistake can follow you into retirement.
What Should Federal Employees Decide Before They Retire?
Federal employees face four big decisions: when to retire, how to elect survivor benefits, how to carry health coverage into retirement, and how to draw the TSP. Each one affects the others. The date you pick can change your pension formula, your supplement, and the years your savings must last, so the order you decide them in matters.
The Three Parts of Your FERS Benefit
A sound approach to FERS retirement planning treats the pension, the supplement, and the TSP as one system rather than three separate accounts. The pension is a monthly payment from the government, based on your salary and your years of service. The FERS supplement is a temporary payment that bridges certain retirees to age 62. The TSP is your own retirement savings, much like a workplace plan in the private sector.
These three pieces pay out on different schedules. The pension lasts for life. The supplement stops at 62. The TSP lasts as long as your balance and your withdrawals allow. Reading them together is the only way to see your real income in any given year.

The Order Matters
Five retirement decisions and why timing matters.
How Your FERS Pension Is Calculated
Your pension rests on three inputs: your high-3 average salary, your years of creditable service, and a multiplier. The high-3 is the average of your highest three consecutive years of basic pay, which are usually your final three years. Your service is the time you earned credit toward retirement. The standard multiplier is 1.0 percent per year of service.
One detail changes the math. If you retire at age 62 or later with at least 20 years of service, the multiplier rises to 1.1 percent per year. On a 30-year career, that small shift can raise your pension by 10 percent for life, which is why your exact date and service total deserve a careful look.
Coordinating that decision is part of a wider set of workplace and rollover planning choices that federal and private-sector workers both face as they near retirement.
The FERS Supplement and the Bridge to Social Security
The FERS supplement is a payment that helps bridge the gap until you can claim Social Security. It applies to retirees who leave at their minimum retirement age with enough service, and it ends the month you turn 62, whether or not you actually file for Social Security then. The supplement also has an earnings test, so wages from a post-retirement job can reduce it.
This is where timing the bridge matters. The choice between the supplement years and your eventual Social Security claim runs alongside the broader question of getting the most from Social Security over your lifetime. The two decisions are linked, and reading them apart can leave income on the table.
Where Your TSP Fits When You Leave
When you separate from federal service, you decide what happens to your TSP. You can leave it in place, move it to an IRA, or combine it with another retirement account. Each path carries different costs, investment options, and withdrawal rules. The TSP is known for low fees, so moving money out is a decision to weigh, not a default step.
This coordination sits at the center of FERS retirement planning, because the order you draw the TSP, the pension, and the supplement drives both your yearly income and your tax bill. Your rollover choices when you change jobs follow similar logic, and the same questions about fees and flexibility apply.
Survivor Benefits and Health Coverage in Retirement
At retirement you elect whether to provide a survivor annuity for a spouse. A full or partial election reduces your monthly pension, but it continues income to your spouse after your death and, in most cases, keeps their access to federal health coverage. Waiving it raises your check now and can leave a gap later. This election is difficult to change once you file, so it deserves real thought.
Health coverage is part of the same decision. To carry federal health benefits into retirement, you generally need to have held them for the five years before you retire. This rule is firm, so check it well before you pick a date.
Timing Your Retirement Date
Much of FERS retirement planning is really about timing. Your minimum retirement age depends on your birth year and sits between 55 and 57 for many people. Retiring at that age with enough service gives you an immediate pension. Leaving earlier, or with fewer years, can mean a reduced or deferred benefit instead.
A date a few months one way or the other can change your high-3, your supplement eligibility, and your leave payout. This is the kind of decision where a second set of eyes can help you compare scenarios before you commit.
How to Choose a FERS Retirement Advisor
If you are looking for a FERS retirement advisor or planner, start with two questions: how is the person paid, and do they act as a fiduciary? A fiduciary has to put your interests first when giving advice. Ask for both answers in writing, and ask who else pays them when you buy a product.
Be careful with names and titles that sound official. The SEC has warned that some firms put words like “federal” in their names, or hint at a government connection, to win the trust of TSP participants. No federal agency endorses a private advisor, and the TSP will not contact you by phone or email asking for your account details.
If Someone Suggests Moving Your TSP Into an Annuity
Some federal employees nearing retirement are pitched a plan to move the TSP into a commercial annuity, sometimes at a free seminar. Before you move any money, compare these four things:
- What you would pay. TSP funds have historically carried very low costs. For 2025, the G Fund’s net expense ratio was 0.034 percent. Many commercial annuities cost more, and indexed and variable contracts may add surrender charges that last for years.
- What you would give up. Money in the TSP can stay invested, come out in installments, or be rolled over later. Money in a contract with a surrender period can cost you to reach.
- Whether you already have lifetime income. Your FERS pension pays for life and can include a survivor benefit, so a second annuity may duplicate part of what you have.
- What the TSP itself offers. You can buy a life annuity through the TSP from its annuity provider, MetLife, with a $3,500 minimum. Once the money is paid out, you cannot cancel it or change the option.
An annuity can make sense for some retirees, for example when you want more lifetime income than the pension provides. It still pays to compare it in writing before you sign. An annuity review looks at the costs, the exit terms, and how the contract fits the rest of your plan.

Five Decisions to Review Before You File
Before you set a date, walk through these five choices and how they affect one another:
- Confirm your high-3 salary and your total years of creditable service, since both feed the pension formula.
- Check whether retiring at 62 with 20 or more years lifts your multiplier to 1.1 percent.
- Decide on the survivor annuity election, because it is hard to reverse after you file.
- Confirm you meet the five-year rule so you can carry health coverage into retirement.
- Map the order you will draw the supplement, the pension, and the TSP to manage taxes.
It helps to look at these decisions together instead of one at a time. They also feed into broader retirement income planning, where the goal is steady, tax-aware income in every year of retirement.

Frequently Asked Questions
What Is the FERS Supplement?
The FERS supplement is a temporary monthly payment that bridges eligible retirees to age 62. It is paid to those who retire at their minimum retirement age with enough service, and it ends the month you turn 62. The payment has an earnings test, so a post-retirement salary can reduce it.
When Can I Retire Under FERS?
You can retire with an immediate pension once you reach your minimum retirement age with enough years of service. That age falls between 55 and 57, depending on your birth year. Different service combinations, such as 30 years at your minimum age or 20 years at age 60, carry different rules.
How Is the FERS Pension Calculated?
Your pension multiplies your high-3 average salary by your years of service and a multiplier. The multiplier is 1.0 percent per year, or 1.1 percent if you retire at 62 or later with at least 20 years. A longer career and a higher final salary both raise the benefit.
Should I Keep My Money in the TSP or Roll It Over?
It depends on fees, the investments you want, and how you plan to take withdrawals. The TSP is known for very low costs, which is a strong reason many people keep it. An IRA can offer more investment choices and more flexible withdrawals, so the right answer turns on your goals rather than a rule of thumb.
Does the FERS Supplement Have an Earnings Limit?
Yes. The supplement is subject to an annual earnings test similar to the Social Security rules. If you earn wages above the limit after you retire, your supplement can be reduced. Income from the pension and the TSP does not count toward that earnings test.
Can I Lose My FERS Pension If I Leave Early?
You do not lose what you earned, but leaving early can change how and when it pays. With enough service you may take a deferred pension later, and in some cases a reduced immediate benefit applies. The details depend on your age and years of service when you separate.
Should I Move My TSP Into an Annuity?
Not without comparing costs and exit terms first. Fees in the TSP have historically been very low, while many commercial annuities cost more and carry surrender charges that can last for years. Your FERS pension already pays lifetime income, so a second annuity may duplicate it. If you want more lifetime income, compare any commercial contract with the life annuity you can buy through the TSP.
Do I Need a Financial Advisor for FERS Retirement Planning?
Not everyone does, but the decisions interact in ways that are easy to miss. A fiduciary advisor can model your date, your survivor election, and your withdrawal order side by side. For more depth, the employer and government retirement planning guide covers how these benefits fit together.
