Understanding Your Pension Accrual Rate

A pension accrual rate is one of the most critical components of a Defined Benefit (DB) pension scheme, such as a "Final Salary" or "CARE" (Career Average Revalued Earnings) plan. It determines how much annual pension you earn for every year you are an active member of the scheme.

How the Accrual Rate Formula Works

The standard formula used by most traditional pension schemes to calculate your retirement income is:

Annual Pension = (Years of Service / Accrual Rate Denominator) x Final Salary

Common Accrual Rates Explained

Accrual rates are typically expressed as a fraction. The smaller the denominator (the bottom number), the more generous the pension scheme is:

• 1/60th Accrual: This is a common rate in many public sector and older private sector schemes. If you work for 30 years, you will receive 30/60ths (or half) of your final salary as an annual pension.
• 1/80th Accrual: Often found in schemes that also provide a mandatory tax-free lump sum. This provides 1/80th of your salary for each year of service.
• 1/40th Accrual: An extremely generous rate, usually reserved for specialized executive schemes or accelerated accrual plans.

Practical Example

Imagine an employee who retires with a Final Salary of £45,000 after 25 years of service in a scheme with a 1/60th accrual rate:

1. Divide years of service by the rate: 25 / 60 = 0.4166
2. Multiply by the salary: 0.4166 x £45,000 = £18,750 per year.

This individual would receive an annual pension of £18,750 for life, usually increasing annually to keep pace with inflation.

Why Accrual Rates Matter for Retirement Planning

Understanding your accrual rate allows you to project your future income with high accuracy. If you find your accrual rate provides a lower "Replacement Rate" (the percentage of your working income that the pension covers) than you require, you may need to consider Additional Voluntary Contributions (AVCs) or personal pension savings to bridge the gap.
