# High 3 Calculator Military high-3 retirement calculator and FERS high-3 calculator. Enter years of service and your three highest-paid years to estimate monthly pension pay. ## What this calculates Estimate your high-3 retirement pension for the military High-3 system or the federal FERS high-3 system. Enter your creditable years of service, the three highest consecutive years of base pay, and your retirement age to see your annual and monthly benefit with the correct accrual multiplier applied automatically. ## Inputs - **Retirement System** — options: Military High-3 (DoD, pre-BRS), FERS High-3 (federal civilian) — Military High-3 applies to members who entered service Sep 8, 1980 through Jul 31, 1986, or who opted out of BRS. FERS High-3 applies to federal civilian employees. - **Years of Creditable Service** — min 0, max 45 — Total creditable years of service at retirement. - **Highest Annual Salary (Year 1 of High 3)** ($) — min 0 — Base pay for the highest of your three consecutive highest-paid years. For military, use monthly base pay x 12 for the rank and longevity held that year. - **Second Highest Annual Salary** ($) — min 0 — Second year of the three highest consecutive years. - **Third Highest Annual Salary** ($) — min 0 — Third year of the three highest consecutive years. - **Age at Retirement** — min 38, max 75 — Age when you separate. FERS multiplier bumps from 1.0% to 1.1% if you retire at 62+ with 20+ years of service. ## Outputs - **High-3 Average Salary** — formatted as currency — Average of your three highest consecutive years of base pay. This is the figure the pension formula multiplies against. - **Multiplier Applied** — formatted as percentage — Accrual rate per year of service used in the benefit formula. - **Annual Retirement Pay** — formatted as currency — Gross annual pension before taxes, Survivor Benefit Plan deductions, or FEHB premiums. - **Monthly Retirement Pay** — formatted as currency — Monthly pension payment before deductions. - **Income Replacement Rate** — formatted as percentage — Annual pension as a percentage of your high-3 average salary. ## Details ## How the high-3 formula works Both the military High-3 retirement system and the FERS high-3 pension use the same core structure. The **high-3 average** is the mean of the three consecutive highest-paid years of base pay (no bonuses, no housing allowance, no overtime). That average is then multiplied by an accrual rate and the number of creditable years of service. **Military high-3 retirement pay chart formula**: Annual pension = high-3 average x 2.5% x years of service, capped at 75% of the high-3 average. A retiring O-5 with a $120,000 high-3 and 22 years earns 55% of $120,000 = $66,000 per year. **FERS high-3 calculator formula**: Annual pension = high-3 average x 1.0% x years of service. If you separate at age 62 or later with at least 20 years of creditable service, the multiplier bumps to 1.1%. A GS-13 with a $105,000 high-3 and 30 years retiring at 62 earns 30 x 1.1% x $105,000 = $34,650 per year. ## Military high-3 retirement vs BRS Military high-3 retirement applies to service members who entered between Sep 8, 1980 and Jul 31, 1986, or who opted out of the Blended Retirement System (BRS) during the 2018 election window. Members who entered on or after Jan 1, 2018, are automatically under BRS, which reduces the multiplier to 2.0% but adds a TSP match. If you are under BRS, use a BRS calculator rather than this high-3 tool. ## FERS high-3 calculator inputs For FERS, the high-3 is based on your basic pay, which includes locality pay but excludes overtime, bonuses, and cash awards. Locality pay is a major component (often 15-40% of salary) and is fully creditable. Run OPM's retirement estimator or use this FERS high-3 calculator to sanity-check your numbers before filing paperwork. Many federal employees also build unofficial FERS high-3 calculator Excel sheets to stress-test promotion and locality scenarios; this tool replaces that spreadsheet with the same math. ## Special category employees Law enforcement officers, firefighters, air traffic controllers, and certain other FERS employees use an enhanced formula: 1.7% per year for the first 20 years plus 1.0% per year after. This calculator uses the standard FERS formula. Adjust manually if you fall into a special category. ## Frequently Asked Questions **Q: What is the high-3 in military retirement?** A: The high-3 is the average of your three highest consecutive years of base pay. Military High-3 retirement pay is calculated as: high-3 average x 2.5% x years of service, capped at 75% of the high-3 average. A member with a $90,000 high-3 and 20 years earns 50% of $90,000 = $45,000 per year. At 30 years it maxes at 75% = $67,500. **Q: How is the FERS high-3 calculated?** A: The FERS high-3 calculator uses: annual pension = high-3 average x 1.0% x years of service. If you retire at 62 or older with at least 20 years, the multiplier is 1.1%. The high-3 includes base pay plus locality pay, but not overtime, bonuses, or awards. A federal employee with a $100,000 high-3 and 25 years retiring before 62 earns 25 x 1.0% x $100,000 = $25,000 per year. **Q: Is there a military high-3 retirement pay chart?** A: Rather than a fixed military high-3 retirement pay chart, the benefit is computed from your specific high-3 average and years of service. A reference example: an E-7 with a high-3 of about $63,600 and 20 years receives 50% = $31,800 per year. An O-5 with a high-3 of $125,000 and 22 years receives 55% = $68,750. Use this calculator with your actual high-3 inputs for an accurate estimate. **Q: Can I build a fers high 3 calculator excel sheet instead?** A: Yes, but the formulas are simple enough that a calculator like this one is usually faster. If you prefer a fers high 3 calculator excel workbook, the core cell formula is =AVERAGE(year1, year2, year3) * IF(AND(age>=62, years>=20), 0.011, 0.010) * years. That single line reproduces the OPM computation for standard FERS employees. Special-category employees (LEO, firefighter, ATC) need an enhanced multiplier. **Q: What counts as creditable service?** A: For military, creditable service includes active duty, qualifying Reserve and Guard service (converted using the points system), and any deposit-credited prior service. For FERS, creditable service includes covered federal employment, unused sick leave (added to length of service at retirement), and certain military service if you pay a deposit. Part-time service is prorated based on actual hours worked. **Q: Does the high-3 average include allowances?** A: No. For military, only base pay counts toward the high-3 average. BAH, BAS, special pays, and bonuses do not. For FERS, the high-3 includes base pay and locality pay, but excludes overtime, night differential, Sunday premium, bonuses, and cash awards. Always pull the actual basic pay figure from your LES or SF-50 for accuracy. --- Source: https://vastcalc.com/calculators/finance/high-3 Category: Finance Last updated: 2026-04-08
