Federal Retirement & TSP Calculator

FERS pension + military buyback + TSP projection — your complete retirement picture.

Your Federal Service

Tell us about your federal career to calculate your FERS pension.

$0

Auto-detects your FERS type and calculates years of service.

Enter your hire date above to auto-calculate, or enter manually below.

100% of unused sick leave adds to your pension computation. 2,087 hrs = 1 year. Check your LES.

Military Service Buyback

Buy back your military time to increase your FERS pension.

Total base pay (not BAH/BAS) earned during your entire military career. Check your military pay records, LES history, or ask DFAS.

If completed, your military time already counts toward your FERS pension.

Interest accrues on your deposit after 2 years of federal service at ~4%/year.

Where to find your total base pay

Best source: Contact DFAS at 1-888-332-7411 and request your earnings statement, or check myPay (mypay.dfas.mil) for LES history.

Alternative: Your HR/payroll office can calculate the exact deposit amount when you file SF-3108.

Important: Deposit must be paid in full before retirement or the option is lost forever.

Thrift Savings Plan (TSP)

Project your TSP balance and optimize your contributions.

Contribute at least 5% to get the full agency match (5% total from your agency).

Roth TSP: 0%

Catch-up contributions are auto-calculated based on your age: $8,000 extra at 50+, $11,250 at ages 60-63 (SECURE 2.0).

Most federal retirees drop 1-2 brackets in retirement.

Additional Retirement Income

Optional — include these for your complete retirement picture.

VA disability compensation is tax-free and not affected by federal retirement.

Check ssa.gov/myaccount for your estimate. FERS employees DO pay into Social Security — WEP does not apply.
