What Is the Rule of 90?

The Rule of 90 is a retirement eligibility guideline where you can retire without penalty if your age plus years of service equal at least 90.

This rule is often used in public employee retirement systems to reward long-term service and allow workers to retire early with full pension benefits.

Formula

Here’s the simple formula:

Your Age + Your Years of Service = Eligibility Score

If your score is 90 or more, you are eligible to retire under the Rule of 90 without facing early retirement reductions.

Examples:

• Age 60 + 30 years of service = 90 → ✅ Eligible
• Age 55 + 28 years of service = 83 → ❌ Not eligible yet

This rule helps employees who have started their careers early retire in their 50s or early 60s with full benefits.
