If you previously served in the military and now work as a federal employee, you may be sitting on one of the most overlooked retirement opportunities available under FERS.

It’s called the military buyback program.

Many federal employees in Puerto Rico are unaware that eligible military service can potentially increase their future federal retirement income significantly. In some cases, buying back military time may help increase pension income, improve retirement eligibility, and create greater long-term financial security.

But despite the financial advantages, many employees delay taking action because the rules can feel confusing.

Questions like these are extremely common:

• Should I buy back military time?
• Is military buyback worth it under FERS?
• How much does military buyback cost?
• Can military service increase my federal pension?
• Does military buyback affect Social Security?

Understanding how military service credit works under the Federal Employees Retirement System (FERS) can help you make smarter retirement planning decisions — especially if your goal is to maximize retirement income and avoid costly mistakes later.

According to the U.S. Office of Personnel Management (OPM), millions of federal employees and retirees are covered under FERS retirement benefits. 

For veterans who transitioned into civilian federal service, military buyback may become one of the most valuable retirement planning strategies available.

 

Military buyback, also called military service credit or military deposit, allows eligible federal employees to receive retirement credit for active-duty military service.

In simple terms, it means your years in military service may count toward your federal civilian retirement pension.

That additional service credit can potentially:

• Increase your FERS pension
• Help you retire sooner
• Improve retirement eligibility
• Increase survivor benefit calculations
• Add more years to your pension formula

Many federal employees are surprised to learn that military service does not automatically count toward civilian retirement benefits under FERS. In most situations, employees must complete a military deposit process to receive full retirement credit.

For federal employees living in Puerto Rico, this can become especially important when building long-term retirement income strategies that combine:

• FERS pension
• Thrift Savings Plan (TSP)
• Social Security
• Veteran benefits
• Personal savings

Your FERS pension is generally based on three main factors:

FERS Pension=High-3 Salary×Years of Service×Multiplier

Military buyback mainly affects the “Years of Service” portion of the formula.

That means additional military service years may increase your pension income for the rest of your retirement.

For example, imagine a federal employee has:

• High-3 salary of $95,000
• 25 years of civilian service
• 5 years of eligible military service

Without military buyback:

95,000×25×1%=23,750

Estimated annual pension:
$23,750

With military buyback included:

95,000×30×1%=28,500

Estimated annual pension:
$28,500

That difference may create thousands of additional retirement dollars every year.

Over a 20–30 year retirement, the long-term financial impact can become substantial.

Many federal employees qualify for military service credit, but eligibility depends on several factors.

Generally, eligible military service may include:

• Active-duty military service
• Army, Navy, Air Force, Marines, Coast Guard
• Certain reserve active-duty periods
• National Guard active service in qualifying situations

However, the rules can vary depending on:

• Retirement system
• Military retirement status
• Type of discharge
• Length of service
• Federal employment history

This is one reason why many federal employees research topics like:

• “Who qualifies for military buyback?”
• “Military deposit rules explained”

Because retirement regulations can be complex, many employees review their records carefully before making retirement decisions.

The military buyback process usually requires paying a military deposit based on a percentage of your military base pay earned during active-duty service.

In many cases, the earlier you begin the process, the lower the cost may be.

Why?

Because interest charges can begin accumulating after certain deadlines.

This is where many federal employees unintentionally lose money.

Waiting too long may increase the total military deposit significantly.

According to OPM retirement guidance, interest may begin accruing if military deposits are not completed within the applicable interest-free period. For employees approaching retirement, understanding these timelines is extremely important.

If you are unsure whether your military service qualifies or how much your deposit may cost, it may help to Schedule a Meeting to review your retirement records and estimate the long-term pension impact before making a final decision.

This is one of the most searched questions related to federal retirement planning.

And in many cases, the answer may be yes.

Why?

Because military buyback can potentially create:

• Higher lifetime pension income
• Earlier retirement eligibility
• Increased survivor benefits
• Greater retirement stability

However, every situation is different.

The financial value of military buyback often depends on:

• Years of military service
• Current federal salary
• Retirement age
• Future pension estimates
• Expected retirement timeline

For some federal employees in Puerto Rico, military buyback may become especially valuable when combined with long-term retirement income planning and TSP strategies.

The key is understanding whether the future pension increase outweighs the cost of the military deposit.

Many federal employees make costly military buyback mistakes simply because they wait too long or misunderstand the rules.

Here are some of the most common issues.

Waiting Too Long to Start the Military Deposit Process

One of the most common mistakes is waiting too long to take action.

Interest charges may continue increasing over time, making the buyback more expensive later.

Employees who begin the process earlier often have more flexibility and potentially lower costs.

Assuming Military Service Automatically Counts

Many employees believe military years automatically apply toward civilian retirement.

Unfortunately, that is not always true.

Without completing the required deposit process, eligible military service may not fully count toward your FERS pension.

Ignoring the Long-Term Retirement Impact

Some employees focus only on the upfront military deposit cost and overlook the long-term retirement income increase.

Even modest annual pension increases may add up significantly across decades of retirement.

This is especially important when planning for:

• Inflation
• Healthcare costs
• Survivor income needs
• Retirement lifestyle goals

Not Coordinating Military Buyback With TSP and Social Security

Military buyback should not be viewed in isolation.

Your retirement strategy should also consider:

• TSP withdrawals
• Social Security timing
• Tax planning
• Survivor benefits
• Healthcare expenses

The most effective retirement plans typically evaluate all income sources together rather than separately.

Military buyback is not just about adding years to your pension.

It is about improving overall retirement confidence.

Federal employees in Puerto Rico often face unique retirement planning considerations, including:

• Cost-of-living concerns
• Healthcare planning
• Long-term income stability
• Tax-efficient retirement strategies
• Inflation risk

Military service credit can potentially strengthen your retirement foundation by increasing predictable pension income over time.

This may help reduce reliance on market-based withdrawals and improve long-term financial flexibility during retirement.

For employees approaching retirement eligibility, now may be the right time to Schedule a Meeting and review how military service credit could affect future retirement income projections.

Military buyback may be one of the most valuable retirement opportunities available to eligible federal employees under FERS.

For veterans who transitioned into federal civilian service, understanding how military service credit affects retirement income can help improve long-term financial planning and potentially increase lifetime pension benefits.

The earlier you understand your options, the more time you may have to make informed retirement decisions.

Whether you are still early in your federal career or approaching retirement eligibility, reviewing your military service history carefully can help you avoid missed opportunities and better maximize your future federal government employee pension.
