High 36 Calculator
What is the High-36 Retirement System?
The High-36 (or High-3) retirement system is a formula used by the U.S. military to calculate retirement pay for service members. Under this system, your retirement pay is based on:
- The average of your highest 36 months of basic pay (usually the last 3 years of service).
- Your years of creditable service (how long you served).
- A 2.5% multiplier for each year of service.
For example:
- If you served 20 years, your retirement multiplier is 50% (20 × 2.5%).
- If you served 30 years, your multiplier is 75% (30 × 2.5%).
This means the longer you serve, the larger your retirement check.
How the High-36 Calculator Works
Our High-36 Calculator automates this process in seconds. Here’s what it does:
- Takes your monthly base pay (the most recent amount, assuming stable pay).
- Calculates the average high-36 pay (in many cases, your last 3 years’ pay is the same, so we use your current monthly base pay).
- Multiplies years of service by 2.5% to find your retirement multiplier.
- Applies the formula: RetirementPay=(AverageHigh−36MonthlyPay×12)×(YearsofService×2.5Retirement Pay = (Average High-36 Monthly Pay × 12) × (Years of Service × 2.5%)RetirementPay=(AverageHigh−36MonthlyPay×12)×(YearsofService×2.5
The result gives you:
- Average High-36 Pay
- Retirement Multiplier (%)
- Estimated Annual Retirement Pay

Example: High-36 Retirement Calculation
Let’s say a service member has:
- Monthly Base Pay: $6,200
- Years of Service: 25
Step 1: Average High-36 Pay = $6,200
Step 2: Retirement Multiplier = 25 × 2.5% = 62.5%
Step 3: Annual Retirement Pay = $6,200 × 12 × (62.5 ÷ 100) $6,200 × 12 × 0.625 = $46,500 per year
So, this retiree would receive $46,500 annually in retirement pay.
