Defined Benefit Pensions: The Holy Grail That's Disappearing

Why They're Called the Holy Grail

A defined benefit (DB) pension does something no other retirement product can: it guarantees you a specific income for the rest of your life, no matter what happens to the stock market, interest rates, or inflation.

You don't manage a pot. You don't make investment decisions. You don't worry about running out of money. On the day you retire, your employer's pension scheme starts paying you a fixed income — typically linked to your salary and years of service — and it keeps paying until you die. If you have a spouse, it usually continues paying a reduced amount to them after that.

No investment risk. No drawdown decisions. No sequence-of-returns anxiety. Just a guaranteed, predictable income for life.

For anyone who's ever stared at a defined contribution pension pot wondering "will this last 30 years?" — a DB pension solves that problem entirely.

How the Calculation Works

Every DB scheme has a formula. The two most common types are final salary and career average (CARE).

Final Salary

The classic formula:

Annual pension = years of service x accrual rate x final salary

The accrual rate is typically 1/60th or 1/80th of your salary per year of service.

Take someone who worked for the same employer for 30 years, with a final salary of £48,000 and a 1/60th accrual rate:

30 x (1/60) x £48,000 = £24,000 per year

That's £24,000 a year, guaranteed, for life. Before state pension. Before any other savings.

With a 1/80th scheme, the same person would get:

30 x (1/80) x £48,000 = £18,000 per year

Some 1/80th schemes also provide a separate tax-free lump sum (typically 3/80ths per year of service), which partly compensates for the lower annual income.

The "final salary" is usually defined as either your actual salary when you leave or an average of your last few years — designed to smooth out any end-of-career changes.

Use the calculator below to see how the formula works with different salaries, service lengths, and accrual rates — and what the equivalent defined contribution pot would need to be.

Career Average (CARE)

Most DB schemes that still exist — particularly in the public sector — have moved from final salary to career average revalued earnings (CARE).

Instead of basing your pension on your salary when you leave, CARE builds up a slice of pension for each year you work, based on your salary that year. Each year's slice is then revalued (increased) annually, usually in line with CPI inflation.

Example: you earn £35,000 in year one. At a 1/57th accrual rate (the current NHS and civil service rate), you bank:

£35,000 x (1/57) = £614 of annual pension

That £614 is then increased by CPI each year until you retire. If you work for 30 years with salary increases along the way, each year adds a new slice at that year's salary, and all previous slices grow with inflation.

CARE is less generous than final salary for people whose salaries rise steeply toward the end of their career. But it's fairer for people whose earnings are relatively flat — you're not penalised for not getting a big promotion at 55.

The Numbers Are Remarkable

To understand the value of a DB pension, consider what it would cost to replicate one.

An annuity — the closest private-sector equivalent — currently pays roughly £6,000-£7,000 per year for every £100,000 of pension pot for a level annuity at age 65, depending on the provider. Inflation-linked annuities pay significantly less upfront — closer to £4,000-£4,500 per £100,000.

So that £24,000/year final salary pension is equivalent to a defined contribution pot of roughly £340,000-£400,000 if you only need a level income. But most DB pensions — particularly in the public sector — are inflation-linked, which makes the equivalent pot much larger: potentially £530,000-£600,000. That's the pot you'd need to replicate what the DB scheme gives you for free.

This is why DB pensions are often described as the most valuable asset someone owns, sometimes worth more than their house. And it's why financial advisers are rightly cautious about anyone considering transferring out of one.

Why They're Disappearing

DB pensions are phenomenally expensive for employers. The employer bears all the investment risk, all the longevity risk (people living longer than expected), and all the inflation risk. If the pension fund's investments underperform, or if members live longer than the actuaries predicted, the employer has to make up the difference.

In the 1960s and 70s, most large UK employers offered DB pensions. It was the standard. By the 1990s, the costs were becoming unsustainable:

• People started living longer. A pension promised in 1970 might have expected to pay out for 10-15 years. By 2000, life expectancy had risen dramatically, and schemes were paying out for 25-30 years.
• Investment returns fell. The high interest rates and equity returns of the 1980s gave way to lower, more volatile returns. Pension funds that had assumed 8%+ annual growth found themselves underfunded.
• Accounting rules changed. FRS 17 and later IAS 19 required companies to show pension deficits on their balance sheets. Suddenly, the true cost was visible to shareholders, and it wasn't pretty.
• Regulation tightened. After the Maxwell scandal and other failures, the Pensions Regulator gained powers to force employers to fund deficits. This turned DB pensions from a vague promise into a hard financial obligation.

The result was a mass closure. First to new members, then to future accrual. Today, almost no private-sector employers offer DB pensions to new employees. The schemes that remain are mostly closed, running down as existing members retire.

The Public Sector Exception

The major exception is the public sector. The NHS, civil service, teachers, police, firefighters, armed forces, and local government all still operate DB pension schemes. These are among the most valuable employment benefits in the country.

Most public sector schemes moved from final salary to CARE between 2014 and 2015 (following the Hutton review), with protected provisions for members close to retirement. The accrual rate is typically 1/57th with CPI revaluation.

Public sector schemes are mostly "unfunded" — meaning there's no investment pot backing the promises. Current pensions are paid from current contributions and general taxation. This makes them cheaper for the government to run in the short term but creates enormous long-term liabilities. The total estimated liability of UK public sector pension schemes exceeds £2 trillion.

Whether this is sustainable is a political question as much as a financial one. But for current members, the benefits are real and contractually guaranteed.

Commutation: The Lump Sum Trade-Off

Most DB schemes offer the option to "commute" — give up some of your annual pension in exchange for a tax-free lump sum at retirement. The exchange rate varies by scheme but is typically 12:1 to 20:1.

At a 12:1 rate, giving up £1,000 of annual pension gets you a £12,000 lump sum. Whether this is a good deal depends on how long you live, what you'd do with the lump sum, and your tax position. There's no universally right answer — it's one of the most personal decisions in retirement planning.

Should You Ever Transfer Out?

Since 2015, it's been possible to transfer a DB pension into a defined contribution pot — taking a "transfer value" (CETV) in exchange for giving up the guaranteed income.

Transfer values during periods of low interest rates were enormous — sometimes 30-40x the annual pension. A £20,000/year DB pension might have offered a transfer value of £600,000-£800,000. This led to a wave of transfers, not all of which were in the member's best interest.

The FCA now requires anyone with a DB pension worth over £30,000 to take regulated financial advice before transferring. The default position of most advisers is: don't transfer. The guaranteed income is almost always worth more than the pot you'd receive, and once you transfer, there's no going back.

There are legitimate reasons to transfer — terminal illness, no dependants, or a strong desire for flexibility and control. But for most people, the guarantee is the whole point. It's the one retirement product that removes the biggest risk of all: running out of money.

Model It

If you have a DB pension alongside other savings — a SIPP, ISA, or state pension — the interaction between them affects your tax position, withdrawal strategy, and how long your other pots need to last. You can build a free scenario to see how the guaranteed income from a DB scheme changes the picture.
