The formula that's been building your retirement since day one

The Pension Formula Nobody Taught You

Most firefighters know they have a pension. Most can tell you roughly what the monthly check will look like. Almost none of them have ever sat down and understood how that number actually gets built — or what they could have done differently if they had known earlier.

That gap costs people money. Not in a single dramatic decision the way the DROP rollover mistake from Issue 1 did. In a quieter way, over years of choices that seemed unrelated to retirement at the time.

Here is the formula. Here is what it actually means. And here is why the decisions you are making right now — regardless of where you are in your career — have more impact on that number than most people ever realize.

Three numbers multiplied together determine every pension check you will ever receive from Fort Lauderdale.

Years of Credited Service × Benefit Rate × Average Final Compensation

Everything flows from those three variables. Understanding what moves each one — and what does not — is the whole game.

Years of Credited Service is straightforward until the DROP enters the picture. Your years of service freeze the day you enter DROP, not the day you walk out the door. Work an 8-year DROP and those eight years do not add to your benefit calculation. The pension is locked on day one of DROP and that frozen number is what deposits into your account every single month for the length of the program.

The Benefit Rate for Fort Lauderdale firefighters is 3.38% per year of credited service. That is not the standard 3% you hear about at most departments — the CBA negotiated a better number. Work 24 years and you are sitting at 81.12%, which puts you right at the plan cap. The difference between 3% and 3.38% sounds like rounding. Over a career it is not. On a $120,000 Average Final Compensation that difference is roughly $10,800 a year in pension income — every year, for the rest of your life, plus whatever the pay steps add on top of it.

Average Final Compensation is calculated as the average of your two highest years of credited service. Not necessarily your final two years — your highest two years. In most cases those are the same thing because pay tends to climb, but understanding the mechanic means you know exactly which years the pension office is pulling. Any compensation that counts as pensionable during those two years feeds the number.

This is where a promotion or a specialty pay assignment earns a second look that most guys never give it. The timing matters most when it falls inside your two highest earning years, which for most people means late in the game — but that is exactly when a lot of guys are tired of the politics and pass on opportunities they would have chased ten years earlier. Picking up a bugle or locking in a specialty assignment that adds $8,000 to your annual base is not just a pay raise. That money moves your Average Final Compensation, which moves your frozen pension benefit, which deposits into your DROP account every month for 8 years, which then pays you every month for the rest of your life — compounding through the pay steps the whole way.

The Fort Lauderdale plan caps at 81% of AFC. At 3.38% per year that ceiling hits right around 24 years of credited service.

Most guys accept 81% as the finish line and move on. The current CBA has something worth knowing before you do that.

Firefighters who have not yet entered DROP can purchase an increase in their maximum benefit accrual — from 81% up to 84.5% — by paying the actuarial cost. That cost can be funded using your Share Plan account, the money that has been accumulating in your name from Chapter 175 premium tax revenues all these years. You do not necessarily have to come out of pocket.

Three and a half additional percentage points on a $120,000 AFC is $4,200 a year in pension income. Over a 30-year retirement, before the pay steps, that is $126,000. Whether the actuarial cost the pension board quotes you is worth that return depends on your specific numbers and your age at retirement. The point is to ask the question before you enter DROP, not after.

The contract allows you to purchase up to five years of prior service as a firefighter at another department or in the military. Those years count toward your benefit as if you were always here. One additional year of credited service at 3.38% on a $120,000 AFC is worth $4,056 a year in pension income for the rest of your life. Find out what your plan charges for that year and you have a real rate of return to evaluate.

What most guys do not know is that your Chapter 175 Share Plan money can fund that purchase through a trustee-to-trustee transfer. Taking 175 money as a distribution at retirement means paying ordinary income tax on every dollar. Using it for a buyback through a trustee-to-trustee transfer is not a taxable event — no cash changes hands and the IRS does not take a cut. You are converting pre-tax dollars directly into permanent pension benefit, which then increases the monthly amount depositing into your DROP account for the length of the program.

The buyback has to happen before DROP entry. Once the benefit is frozen the math on purchasing additional service credit falls apart completely. This topic gets a full issue of its own — but if you have prior service sitting unclaimed, ask the pension office what it would cost before you go any further in your career without looking at it.

Two Fort Lauderdale firefighters, same salary history. One enters DROP at 20 years of service. The other waits until 24.

The conventional thinking is that waiting is always better. The 24-year guy locks a larger pension check and a larger DROP balance. That is real. At 3.38% per year, four additional years of credited service is 13.5 more percentage points of benefit — on a $120,000 AFC that is roughly $16,200 more per year in pension income compounding inside the DROP for 8 years before he ever sees it.

But the 20-year guy walks out the door four years earlier. His lump sum goes into the market four years before his colleague's does. At 8% annual growth that head start produces roughly $210,000 in additional compounding that the 24-year guy never captures — his money is still sitting inside the pension fund earning whatever the fund earns.

Which one comes out ahead depends on your actual benefit numbers, what the fund earns during your DROP versus what the market does in those same four years, and how long you live. There is no universal right answer.

The firefighter who understands this at year 12 has time to think it through properly. The one who first looks at it at year 19 is making a rushed decision on one of the most significant financial choices of his career.

Early career — The benefit rate is fixed at 3.38%. Years of service accrue automatically. The variable you can influence is AFC and the decisions that affect it happen during your working years, not at the end of them. Pay attention to what counts as pensionable compensation and think twice before passing on a promotion or specialty assignment that falls inside your highest earning years.

Mid-career — You are entering the window where AFC starts to matter most. Your two highest earning years are likely still ahead of you. Knowing which years those will be and what falls inside them is worth understanding now rather than at year 22.

Approaching DROP eligibility — Run the timing comparison before you file. Ask the pension office for a quote on the 84.5% buy-up while you have them on the phone. Make the decision with numbers in front of you, not gut feel.

Every decision covered in this issue — pensionable raises, buybacks, DROP timing, the buy-up — feeds directly into one number. The monthly benefit you lock in the day you enter DROP. When you retire you will be asked to choose a pension option that may reduce that number permanently to provide income for a surviving spouse. The bigger the number you bring to that table, the more flexibility you have when you get there.

Call the pension office or log into the portal and ask for three things:

If you have prior service at another department or military time, ask what a buyback would cost while you have them on the phone.

Write those numbers down next to the present value table from Issue 2. The difference between your two projected benefit levels is not just a monthly check difference — it is an asset value difference in the millions. Whether two more years is worth it to you is a personal decision. It should at least be an informed one.

Talk soon.

This is education, not financial advice. Benefit rates, DROP provisions, buy-up options, and buyback eligibility are governed by the Fort Lauderdale Police and Fire Retirement System ordinance and the current collective bargaining agreement. Confirm all calculations, eligibility windows, and how 175 funds can be used with the pension office before making any decisions.
