Let's compare two individuals: one with a Defined Benefit (DB) pension (e.g., a teacher), and one with a Defined Contribution (DC) pension (e.g., a private sector employee).
| Person | Job | Pension Type |
|---|---|---|
| Sarah | Secondary School Teacher | Defined Benefit (DB) |
| James | Marketing Manager (private sector) | Defined Contribution (DC) |
Both:
Work from age 25 to 65 (40 years)
Earn £35,000/year on average over their career
Receive the full State Pension (currently ~£11,500/year)
Typical formula:
1/57th of average salary - years of service
So:
£35,000 - (40 - 57) = £24,561/year DB pension income
£11,500 State Pension
= £36,061/year total income in retirement (inflation-linked)
Guaranteed for life
Adjusted annually for inflation
No investment risk
He and his employer contribute 8% total of salary each year:
£35,000 - 8% - 40 years = £112,000 contributions
Let&'s assume 5% annual investment growth, Pot grows to ~£260,000 at age 65
Using a conservative annuity rate of 4%:
£260,000 - 4% = £10,400/year pension income
£11,500 State Pension
= £21,900/year total income in retirement
Not inflation-proof unless he buys a costly inflation-linked annuity
Risk of running out of money if he lives long
Subject to market ups & downs
| Feature | Sarah (DB) | James (DC) |
|---|---|---|
| Private Pension Income | £24,561/year | £10,400/year |
| State Pension | £11,500/year | £11,500/year |
| Total Retirement Income | £36,061/year | £21,900/year |
| Guaranteed? | Yes | No |
| Indexed to Inflation? | Yes | Optional (expensive) |
Sarah (DB): £36,000 - 25 = £900,000+ (inflation-adjusted!)
James (DC): £21,900 - 25 = £547,500 (flat)
Thats a £350,000+ difference, not accounting for inflation protection or lifespan.
Alright, let's see how things change for James (DC pension) if he:
Invests more aggressively
Retires later (at age 68 instead of 65)
Salary: £35,000
Contributions: 8% of salary for 40 years = £112,000
Retirement age: 65
Growth rate: 5%
Pot at retirement: ~£260,000
Annuity rate: 4% à ¢" ' £10,400/year
Lets assume James still retires at 65, but aims for a 7% average return (reasonable with long-term equity investing).
Estimated pot at 65: ~£420,000
4% annuity, £16,800/year
State Pension: £11,500
= £28,300/year retirement income
Better, but still £7,700 less than Sarah (with her DB pension)
Now assume:
James contributes for 43 years instead of 40
He still earns 5% investment returns
Shorter expected retirement = cheaper annuity
His pot:
Grows from £260,000, ~£310,000
Annuity rate for age 68 is higher: ~5.2%
£310,000 - 5.2% = £16,120/year
State Pension: £11,500
= £27,620/year
Closer to DB level, but:
He worked 3 years longer
Still less predictable income
7% return for 43 years à ¢" ' Pot = ~£520,000
Annuity at 68 (5.2%) = £27,000/year
£11,500 State Pension = £38,500/year
Now James slightly overtakes Sarah, but only by:
Investing aggressively
Working 3 extra years
Taking on all market risk himself
| Scenario | James' Pension Pot | Annuity Income | Total Income (w/ State Pension) |
|---|---|---|---|
| Base Case (5%, retire at 65) | £260,000 | £10,400 | £21,900 |
| Aggressive (7%, retire at 65) | £420,000 | £16,800 | £28,300 |
| Later Retirement (5%, age 68) | £310,000 | £16,120 | £27,620 |
| Both (7%, age 68) | £520,000 | £27,000 | £38,500 |
| Sarah (DB, retire at 65) | N/A (guaranteed) | £24,561 | £36,061 |
