How to Use FERSFree to Plan Your Retirement (Step-by-Step Guide)

Planning federal retirement can feel overwhelming because it involves multiple moving parts:

  • FERS pension
  • TSP savings
  • Social Security
  • VA disability
  • Healthcare (FEHB/Medicare)

FERSFree is designed to bring all of these together into one system so you can make informed decisions.

Step 1: Enter Your Profile Information

Start by entering your basic information:

  • Age
  • Years of federal service
  • Expected retirement age
  • Salary (high-3 estimate)
  • Military service (if applicable)
  • VA disability (if applicable)

This forms the foundation for all calculations.

Step 2: Calculate Your FERS Pension

Next, use the FERS calculator to estimate your pension.

This includes:

  • High-3 salary
  • Years of service
  • Multiplier (1.0% or 1.1%)

Test multiple scenarios:

  • Retire at 57 vs 60 vs 62
  • With vs without military buyback

Step 3: Project Your TSP Income

Use the TSP tool to estimate how much income your savings can generate.

Compare:

  • Different withdrawal rates (3%, 4%, 5%)
  • Monthly income outcomes
  • Longevity of your balance

This helps you understand how much of your retirement depends on TSP.

Step 4: Add Additional Income Sources

FERSFree allows you to layer multiple income streams:

  • VA disability
  • Social Security (estimated)
  • Military retirement
  • Other pensions

This is where your plan becomes realistic.

Step 5: Build Your Retirement Timeline

This is one of the most important features.

Map out:

  • Retirement age (pension start)
  • FERS Supplement (if applicable)
  • Age 62 (Social Security eligibility)
  • Age 65 (Medicare)

You will see how your income changes over time.

Step 6: Identify Income Gaps

Once your timeline is built, look for gaps:

  • Early retirement gap before Social Security
  • Loss of FERS Supplement at age 62
  • Healthcare cost increases

Then adjust:

  • TSP withdrawals
  • Retirement age
  • Social Security timing

Step 7: Compare Multiple Scenarios

Do not rely on a single plan.

Compare:

  • Retire early vs wait
  • Take Social Security at 62 vs 70
  • Different TSP withdrawal strategies
  • With vs without buyback

This is where the tool provides the most value.

Step 8: Estimate Your Total Monthly Income

At this stage, you should have:

  • Pension estimate
  • TSP monthly income
  • Additional income sources

Combine them to determine:

Your total retirement income at each stage of life

Step 9: Stress-Test Your Plan

Ask:

  • What happens if markets underperform?
  • What if expenses increase?
  • What if I retire earlier than planned?

Adjust inputs and re-run scenarios.

Step 10: Use Your Results to Make Decisions

FERSFree is not just for numbers—it is for decisions.

Use it to answer:

  • When should I retire?
  • Do I need more TSP savings?
  • Should I delay Social Security?
  • Is military buyback worth it?

5 Common Mistakes When Using Retirement Tools

  1. Only running one scenario
  2. Ignoring timeline changes
  3. Overestimating TSP withdrawals
  4. Not including all income sources
  5. Focusing only on totals instead of monthly income
