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.

Types of DB Pension

Type How Salary Is Calculated
Final salary Based on salary at retirement
Career average (CARE) Average salary over entire career
Hybrid schemes Mix of DB and DC elements

DB Pension Benefits

Benefit Details
Guaranteed income Know exactly what you’ll receive
Inflation protection Typically linked to CPI
Longevity protection Paid for life, however long
Spouse pension Usually 50% to surviving spouse
No investment risk Employer bears market risk
No decisions Income set by formula

DB Pension Drawbacks

Drawback Details
Inflexibility Can’t change amount or timing easily
Scheme limitations Early retirement reduces pension
Death before retirement Limited benefits (varies by scheme)
Less common Most private sector closed to new members
Complex rules Harder to understand

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 Full pot to beneficiaries
Portability Take with you between jobs
Control Choose investments
Transparency Know exactly what you have
Access from 55/57 Earlier than State Pension

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

Income Certainty Comparison

Factor DB Pension DC Pension
Know income now? Yes (can calculate) No (depends on markets)
Guaranteed for life? Yes No (unless buy annuity)
Inflation protected? Usually Your decision
Spouse protected? Usually Your decision

Who Has What?

DB Pensions (Where They Still Exist)

Sector Status
NHS Active (CARE scheme)
Teachers Active (CARE scheme)
Civil Service Active (CARE scheme)
Police Active
Local Government Active (LGPS)
Armed Forces Active
Universities (USS) Active (but reduced)
Large private sector Mostly closed
Smaller companies Very rare

DC Pensions (Common)

Context Example
Auto-enrolment (most jobs) Workplace pension (Nest, People’s Pension, etc.)
Personal pensions SIPP, stakeholder pension
Group personal pensions Employer-facilitated SIPP

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
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.

Match employer maximum Never leave free money
Increase with pay rises Save the raises

Check Your Investments

Factor Action
Default fund Often fine, but check it
Fees Lower is better
Risk level Age-appropriate
Diversification Global exposure

Review Regularly

Frequency Action
Annually Check statement, contribution level
Every 5 years Consider increasing contributions
Near retirement Plan withdrawal strategy

Having Both DB and DC

Many people have both:

Integration Strategy

Step Action
1 Value your DB income (guaranteed floor)
2 Build DC for flexibility on top
3 Use DC for early retirement bridge
4 Take DB from Normal Pension Age

Example Combined Approach

Age Income Source
55-60 DC drawdown (flexible)
60-67 DB pension starts + DC top-up
67+ DB + DC + State Pension

Summary Comparison

If You Have… Key Points
DB pension Treasure it. Don’t transfer without strong reason and advice. Enjoy the security.
DC pension Maximise contributions. Keep costs low. Plan for retirement income.
Both Great position. Use each for its strengths.
