Use CalculatorFederal employees, state and local government workers, military personnel, and government contractors navigate complex compensation, retirement, and travel systems that require precise calculations. From projecting FERS retirement income with High-3 salary calculations and TSP projections, to understanding GS pay scales with locality adjustments, CPAF contract award fees, GSA per diem rates for official travel, and public pension benefits—our Government & Public Sector calculators bring clarity to federal employment math using 2026 official data from OPM, GSA, and federal regulations.
Why Use Our Government & Public Sector Calculators
Government employment involves unique financial systems that civilian calculators do not address. FERS retirement requires understanding the three-tier system (pension + Social Security + TSP), High-3 base pay rules (excluding locality pay), and the FERS Supplement for early retirees. GS pay calculations must account for the 1% 2026 base pay raise, frozen locality rates, and the 2,087-hour federal work year. Cost Plus Award Fee contracts under FAR 16.404 involve subjective evaluation scoring that determines fee percentage. GSA per diem has first/last day 75% rules and location-specific rates. Our calculators incorporate these federal-specific rules and 2026 official data for accurate results you can rely on for career and retirement planning.

Frequently Asked Questions
Are these calculators based on official government data?
Yes. Our Government & Public Sector calculators use 2026 official data from OPM (GS pay tables, FERS formulas), GSA (per diem rates), and FAR 16.404 (award fee regulations). Data is updated annually following federal budget and pay adjustment announcements. We reference OPM.gov, GSA.gov, and official federal regulations for all formulas and rates.
What is the difference between GS base pay and locality-adjusted pay?
GS base pay is the standard rate before location adjustments, published by OPM for grades 1-15, steps 1-10. Locality pay is an additional percentage added to base pay based on your duty station (ranging from 17.51% Rest of U.S. to 44.61% San Francisco). Your actual salary is base pay multiplied by (1 + locality percentage). Our GS Pay Scale Calculator handles both components.
How accurate is the FERS retirement estimate?
The FERS calculator uses official OPM formulas: High-3 average base pay × years of service × multiplier (1.0% or 1.1%). It projects TSP growth using standard compound interest formulas. Results are directionally accurate for planning, but actual benefits depend on your specific service history, retirement date, and TSP investment performance. Always verify with your agency HR and OPM retirement services for official estimates.
Do you store any of my government employment data?
No. All calculations run entirely in your browser. We do not collect, transmit, or store any salary information, service years, retirement dates, or travel data. Your federal employment information never leaves your device, ensuring privacy and security for sensitive government employment details.
Can contractors use the GSA per diem calculator?
Yes. Government contractors on official travel typically follow the same per diem rules as federal employees, per their contracts. However, verify your specific contract terms—some contractors use different reimbursement structures. The calculator provides GSA rates for reference, but your actual reimbursement depends on contract terms.
