Formulas and Methodology

Final Salary Formula

Annual Pension = Final Salary × (Accrual Rate × Years of Service)
Lump Sum = Final Salary × (Lump Sum Rate × Years of Service)

Typical accrual rate is 1/80th (1.25%) per year of service, with lump sum at 3/80ths.

Career Average Formula

Annual Pension = Career Average Salary × Accrual Rate × Years of Service
Lump Sum = Career Average Salary × Lump Sum Rate × Years of Service

Career average salary is typically revalued annually by CPI or other inflation measure.

Integration Formula

Integrated Pension = Gross Pension - (State Pension × Integration Rate)

Integration reduces your occupational pension to account for State Pension benefits.

Frequently Asked Questions

What is a defined benefit pension?

A defined benefit (DB) pension provides a guaranteed retirement income based on your salary and years of service, rather than investment returns. The benefit is defined by a formula.

What's the difference between final salary and career average?

Final salary schemes base your pension on your salary at retirement, while career average schemes base it on your average earnings throughout your career, typically revalued for inflation.

How do accrual rates work?

Accrual rates determine how much pension you build up each year. For example, 1/80th means you accrue 1.25% of your salary as annual pension for each year of service.

What is pension integration?

Integration reduces your occupational pension to account for State Pension benefits, ensuring your total retirement income is appropriate.

Can I commute my pension?

Many DB schemes allow you to exchange part of your annual pension for a larger tax-free lump sum at retirement, subject to Revenue limits.
