Maximum cap: 50%
2. Blended Retirement System Formula
M=2y
- Base calculation is 2% per year
- Adjusted up to a maximum of 40–50% depending on service time
3. Monthly Pension Formula
Pmonthly=BasePay×100M
4. Annual Pension Formula
Pannual=Pmonthly×12
Example Calculation
Let’s understand how the calculator works with a real example.
Scenario:
- Years of Service = 20
- Monthly Base Pay = $5,000
- Retirement Type = High-3
Step 1: Calculate Multiplier
2.5% × 20 years = 50%
Step 2: Monthly Pension
| Item | Value |
|---|---|
| Base Pay | $5,000 |
| Multiplier | 50% |
| Monthly Pension | $2,500 |
Step 3: Annual Pension
| Item | Value |
|---|---|

|---|---|---|---|
| 10 years | 25% | 20% | $1,250 / $1,000 |
| 15 years | 37.5% | 30% | $1,875 / $1,500 |
| 20 years | 50% | 40% | $2,500 / $2,000 |
| 25 years | 50% (capped) | 50% | $2,500 / $2,500 |
How Retirement Multiplier Affects Your Pension
The retirement multiplier is the most important factor in determining your pension amount. Even a small increase in percentage can significantly impact your lifetime earnings.
For example:
- 40% multiplier = lower pension
- 50% multiplier = significantly higher pension
This is why reaching 20+ years of service is often a key milestone.
