What Is a Pension Buyback?
A pension buyback allows you to purchase additional years of credited service — typically from prior military service or other qualifying employment — and add them permanently to your pension formula. Every year you purchase counts as if you worked that year at the FDNY. You pay a lump sum (or payroll deductions) today. Your pension pays more every month for the rest of your life.
Who Qualifies for an FDNY Military Service Buyback
FDNY members may purchase credit for prior honorable active military service through the NYC Fire Department Pension Fund (NYCFPF). The most common qualifying service is time served in the U.S. Armed Forces before joining the FDNY, or military leave taken during your career.
General eligibility conditions:
- Service must have been active duty with an honorable discharge
- The buyback must be completed before your retirement date — you cannot purchase service after you separate
- Maximum purchasable credit is typically capped (verify the current limit with the FDNY Pension Fund directly)
- Members in both Tier 2 and Tier 3 may have buyback options, though the formulas and costs differ
Prior city service from another NYC agency may also be purchasable under separate provisions. The pension fund can tell you what qualifies for your specific situation.
The Math: How Much Does Your Pension Actually Increase?
This is the only number that matters. A pension buyback is a financial decision, not a sentimental one. The question is: how much does each purchased year add to your annual pension?
Your pension formula determines the answer. For FDNY Tier 2, the commonly cited benchmark is a pension worth approximately 50 percent of final average salary (FAS) at 20 years of service — the "half pay" rule most members know. Each additional year of service beyond that adds incrementally to the total.
When you buy back a year of prior service, you are effectively adding that year to your credited service total. For a member with a $110,000 final average salary, the pension impact of one additional credited year is a meaningful, permanent addition to lifetime income.
"Every year you purchase is a year you already served. You earned it. The question is whether it is worth paying for twice."
The FDNY Pension Fund will give you an official pension projection showing your estimated annual benefit with and without the purchased service. That difference — the annual pension increase — is the number you divide against your buyback cost.
The Break-Even Calculation
The break-even is simple arithmetic:
Break-Even Formula
Break-even years = Total buyback cost ÷ Annual pension increase from purchased service
Example: If buying two years of military service costs $48,000 and increases your annual pension by $5,500, your break-even is approximately 8.7 years. If you retire at 47 and live to 75 or beyond, you collect that extra $5,500 for nearly 28 years — a total of $154,000 in additional pension income on a $48,000 investment.
Break-even benchmarks most members find useful:
| Break-Even | General Verdict | Why |
|---|---|---|
| Under 8 years | Strong case to buy | Most members easily outlive this threshold in retirement |
| 8–12 years | Good case for most | Average retirement spans 20+ years; still a strong net positive |
| 12–18 years | Health-dependent | Longevity and family history matter more at this range |
| Over 18 years | Scrutinize carefully | High cost relative to benefit; verify pension fund numbers |
These are general reference points, not personalized advice. Your actual numbers from the pension fund will determine where your buyback lands.
What the Buyback Costs and How Payment Works
The cost of an FDNY pension buyback is calculated by the pension fund using actuarial factors — your current salary, the years being purchased, your age, and interest rates. You cannot calculate this accurately on your own. The pension fund is the authoritative source.
What members generally experience:
- Costs per year of service typically range from roughly $10,000 to $40,000 or more depending on salary and years of service
- Payment can often be made as a lump sum or through payroll deductions over a period of time
- Some members use a 457(b) distribution to fund a lump-sum buyback — this has tax implications that should be modeled before executing
- Interest accrues on unpaid balances if you choose installments, increasing the total cost
Request the official buyback cost statement early. Processing takes time, and the deadline is your retirement date.
The Tax Picture
Two facts that improve the buyback math for New York residents:
1. NY State does not tax FDNY pension income. The additional pension dollars from a buyback are exempt from New York State and City income tax. The benefit is larger in net terms than the gross number suggests.
2. Buyback payments are made with after-tax dollars. There is generally no deduction for the cost of purchasing service credit. You are paying with money that has already been taxed. Factor this into your cash-flow planning.
Federal tax still applies to FDNY pension income. Your pension increase will be partially offset by federal income tax, depending on your bracket in retirement.
The One Deadline That Catches Members Off Guard
The buyback must be completed before you retire. This sounds obvious, but in practice many members get caught. Here is what happens: a member decides to retire, submits paperwork, and then remembers they had military service they could have purchased. The window is closed.
If you have any qualifying prior service, start the inquiry with the FDNY Pension Fund at least 12 to 18 months before your target retirement date. The application, actuarial calculation, and payment processing all take time. Waiting until the final months of your career is a risk you do not need to take.

Is It Worth It? The Honest Verdict
For most FDNY members with qualifying military service and a break-even under 12 years: yes, the buyback is worth serious consideration. A pension is a lifetime annuity. The income it produces is guaranteed, inflation-adjusted in many formulas, and NY-exempt. Buying more of it at a reasonable cost is one of the few genuinely low-risk retirement decisions available.
Where members get into trouble is treating the buyback as automatic without running the numbers. A $50,000 buyback that adds $1,800 per year to a Tier 3 pension has a 27-year break-even. That changes the calculus entirely.
The steps that matter:
- Request the official buyback cost statement from the FDNY Pension Fund
- Get your pension projection with and without the purchased service
- Calculate your break-even and compare it to your realistic retirement horizon
- Decide how to fund the buyback (lump sum, payroll deductions, or 457(b) distribution — each has different tax consequences)
- Start at least 12 months before your retirement date
The 457(b) Connection
Some members fund a lump-sum buyback with a 457(b) distribution. This can work — but it is a taxable event in the year of withdrawal, and the timing affects your Roth conversion window. Model the tax cost of using 457(b) dollars versus paying from after-tax savings before deciding. The two decisions are linked.
