How Defined Benefit Pensions Work
The Promise
A DB pension promises you a specific retirement income based on:
- Your salary (final or career average)
- Years of service
- Scheme accrual rate
Formula: Annual pension = Years × Accrual rate × Salary
Example: Final Salary DB
| Factor |
Example |
| Final salary |
£50,000 |
| Years in scheme |
30 |
| Accrual rate |
1/60th |
| Annual pension |
30 × 1/60 × £50,000 = £25,000/year |
Plus: Usually increases with inflation (CPI) and provides spouse pension on death.
Example: Career Average DB
| Factor |
Example |
| Career average salary |
£40,000 (average over career) |
| Years in scheme |
30 |
| Accrual rate |
1/49th |
| Annual pension |
30 × 1/49 × £40,000 = £24,490/year |
Note: Career average is revalued annually, so average salary grows over time.

How Defined Contribution Pensions Work
The Pot
A DC pension builds a pot of money from:
- Your contributions
- Employer contributions
- Tax relief
- Investment growth
Your retirement income depends on:
- How much is in the pot
- How you choose to take it (drawdown, annuity, lump sums)
Example: DC Pension
| Factor |
Amount |
| Your contribution (5%) |
£2,500/year |
| Employer contribution (3%) |
£1,500/year |
| Tax relief (on your contribution) |
£625/year (basic rate) |
| Total annual input |
£4,625 |
Over 30 years at 6% growth: Approximately £365,000 pot
Potential income from pot:
- 4% withdrawal = £14,600/year
- Annuity purchase = ~£17,500/year (rates vary)
DC Pension Benefits
| Benefit |
Details |
| Flexibility |
Choose how and when to take income |
| Death benefits |

| Portability |
Take with you between jobs |
| Control |

| Access from 55/57 |

DC Pension Drawbacks
| Drawback |
Details |
| Investment risk |
Markets can fall |
| Longevity risk |
May run out of money |
| Decisions required |
Must manage investments and withdrawals |
| No guarantee |
Income depends on performance |
| Inflation risk |
Must manage inflation yourself |
| Fees |
Can erode value |
DB vs DC: Income Comparison
Same Contributions, Different Outcomes
Scenario: £4,000/year total contributions for 30 years
DB result (if it offered 1/80th accrual):
- Guaranteed pension based on salary
- Inflation-linked for life
- Employer funds any shortfall
DC result (at 6% growth):
- ~£330,000 pot
- Income depends on how you use it
- Investment risk on you

Valuing Your DB Pension
Transfer Value
DB schemes provide a “Cash Equivalent Transfer Value” (CETV):
- The lump sum you’d receive to give up DB benefits
- Often £20-40 for each £1 of annual pension
- Not necessarily a fair swap
Why CETVs Can Be Misleading
| Factor |
Reality |
| CETV seems high |
But buying equivalent annuity costs similar |
| Freedom appears attractive |
But you lose guarantees |
| Investment hopes |
Markets can disappoint |
| Longevity risk |
You might live 30+ years |
True Value of DB
£20,000/year DB pension (inflation-linked, with spouse pension):
- To replicate: Would need ~£500,000-800,000 pot
- CETV offered might be only £400,000
- Gap represents the value of guarantees
Should You Ever Transfer Out of DB?
The Strong Default: Keep DB
| Reason to Keep |
Explanation |
| Guarantees |
Impossible to replicate cheaply |
| No risk |
Investment decisions not required |
| Inflation protection |
Automatic in most schemes |
| Spouse protection |
Often 50% pension on death |
| Simplicity |
No management required |
Rare Circumstances to Consider Transfer
| Situation |
Why Transfer Might Make Sense |
| Terminal illness |
May get better death benefits from DC |
| No dependents |
Spouse pension is wasted |
| Very high CETV |
Exceptional circumstances only |
| Scheme in trouble |
Extremely rare, usually PPF protects |
Legal Requirements
| Requirement |
Details |
| Over £30,000 CETV |
Must take regulated financial advice |
| Advice must be independent |
From FCA-authorised adviser |
| Adviser recommends transfer |
Required for transfer to proceed |
| Cost |
£1,000-5,000 for advice |
Key message: The vast majority of people should NOT transfer out of DB pensions.
