Federal Employee FIRE Starter Pack

FERS Supplement Bridge Guide

The Supplement matters because early retirement is not just about lifetime income. It is about what keeps the bridge years from chewing through your portfolio before age 62.

What it is

The FERS Special Retirement Supplement is a bridge payment that can approximate the Social Security benefit earned through federal service until age 62. It is not forever income. It is a timing tool.

Why it matters for FIRE

It can reduce portfolio withdrawals during the most fragile early-retirement years.
It changes the drawdown picture between separation and age 62.
It can make a "not yet" plan look much closer once the bridge is counted correctly.

Rough worksheet prompts

Planned retirement age
Years until age 62
Estimated monthly Supplement
Estimated annual withdrawal pressure reduced
Total bridge support across the pre-62 years

What to verify

Whether your retirement path actually qualifies
Whether your assumed amount is remotely realistic
Whether your plan is over-dependent on a bridge assumption you have not confirmed

Decision question

If the bridge income disappeared, would the plan still work? If the answer is no, the issue is not the worksheet. The issue is the fragility of the plan.
