UK Defined Benefit Pension Calculator — 2026-27
Work out what your NHS, LGPS, Teachers’, USS or Civil Service pension will pay.
Estimate your defined benefit pension at retirement. Supports NHS 2015 (1/54), LGPS 2014 (1/49), Teachers’ 2015 (1/57), USS post-2016, Civil Service Alpha, plus legacy final-salary schemes. Model commutation to a tax-free lump sum, income tax on pension income, and compare to an equivalent defined contribution pot.
Estimates only. Scheme rules and commutation factors change. Always check your Annual Benefit Statement and seek FCA-regulated advice before transferring or commuting.
How UK defined benefit pensions are calculated
The defined benefit formula
Annual pension = Pensionable salary × Years of service × Accrual rate. For a career-average (CARE) scheme like NHS 2015 or LGPS 2014, “salary” is the revalued average of your pensionable earnings across your career. For a legacy final-salary scheme like NHS 1995 or pre-2014 LGPS, “salary” is your pay at or near retirement.
The accrual rate is almost always quoted as a fraction: 1/54 in NHS 2015 means you earn 1/54th of your pensionable pay as annual pension for each year of service — or roughly 1.85%. Over 30 years that’s 30/54 = 55.5% of final (or career-average) pay, payable for life and index-linked to CPI.
| Example | Pension |
|---|---|
| NHS 2015 · £52,000 · 30 years | £52,000 × 30 × (1/54) = £28,889/yr (55.6% of pay) |
| LGPS 2014 · £38,000 · 25 years | £38,000 × 25 × (1/49) = £19,388/yr (51.0%) |
| Teachers’ 2015 · £45,000 · 30 years | £45,000 × 30 × (1/57) = £23,684/yr |
| USS · £55,000 · 25 years | Pension £55,000 × 25 × (1/75) = £18,333/yr + 3× automatic lump £55,000 |
| Alpha (Civil Service) · £40,000 · 30 years | £40,000 × 0.0232 × 30 = £27,840/yr |
CARE revaluation vs final salary
In CARE schemes, each year’s accrued pension slice is revalued every year until retirement — NHS 2015 uses CPI + 1.5%, Teachers’ 2015 uses CPI + 1.6%, LGPS 2014 uses CPI, Alpha uses CPI. This calculator simplifies by assuming your “salary” input already represents the revalued average. For rough planning this is usually close enough.
State Pension on top
Your DB pension is on top of the new State Pension, which pays £221.20/week (£11,502/yr) in 2026-27 if you have 35 qualifying NI years. A 30-year NHS member on £52k reaches around £40,400/yr gross combined — comfortably above the Pensions and Lifetime Savings Association “Moderate” retirement standard of £31,300/yr.
NHS, LGPS, Teachers’, USS, Alpha — accrual rates and key features
| Scheme | Key details |
|---|---|
| NHS 2015 | CARE 1/54 · Revaluation CPI + 1.5% · NPA = State Pension Age → Main scheme for NHS staff since April 2022. Commute to lump sum at 12:1. |
| NHS 2008 (closed) | Final salary 1/60 · NPA 65 → Benefits earned between April 2008 and March 2022. No automatic lump sum. |
| NHS 1995 (closed) | Final salary 1/80 + 3/80 automatic lump sum · NPA 60 → Pre-April 2008 service. Automatic lump sum = 3× pension, tax-free. |
| LGPS 2014 | CARE 1/49 · Revaluation CPI · NPA = State Pension Age → Local Government Pension Scheme. 6.8 million members. Most generous CARE accrual. |
| LGPS pre-2014 (closed) | Final salary 1/60 (post-2008) or 1/80 + 3/80 lump (pre-2008) → Legacy benefits preserved — final salary link kept on the old “underpin”. |
| Teachers’ 2015 (TPS) | CARE 1/57 · Revaluation CPI + 1.6% · NPA = State Pension Age → Teachers’ Pension Scheme. Covers all state-school and most academy teachers. |
| Teachers’ Final Salary (closed) | 1/60 (2007–2015) or 1/80 + 3× lump (pre-2007) · NPA 60 → Legacy final salary section, benefits preserved after 2015 CARE move. |
| Civil Service Alpha | CARE 2.32% of pensionable earnings · Revaluation CPI · NPA = State Pension Age → Main civil service scheme since April 2015. Replaced classic/premium/nuvos. |
| USS (post-2016) | CARE 1/75 + automatic 3× lump sum · Salary threshold £70,296 (2024) → Universities Superannuation Scheme. Above the threshold, contributions go to the Investment Builder (DC). |
| Armed Forces AFPS 15 / Police CARE / Firefighters’ | CARE with scheme-specific accrual → AFPS 15: 1/47. Police 2015: 1/55.3. Firefighters’ 2015: 1/59.7. |

Should you commute UK DB pension to a lump sum?
How commutation works in UK DB schemes
Most UK public sector DB schemes let you give up part of your annual pension in exchange for a tax-free lump sum, at a fixed rate set by the scheme. The standard commutation factor across NHS, LGPS, Teachers’ and Civil Service schemes is 12:1 — for every £1 of annual pension you surrender, you receive £12 as a one-off tax-free lump sum. Some scheme factors are considerably lower (USS is currently around 10:1 on added years), which weakens the case for commutation.
The 25% tax-free maximum
HMRC allows you to take up to 25% of the capital value of your pension as a tax-free lump sum, subject to the Lump Sum Allowance of £268,275 (2026-27). The capital value is roughly 20× your annual pension plus any automatic lump sum. In NHS 1995 and pre-2007 Teachers’, the automatic 3/80 or 3× lump already uses up much of the 25% — leaving less room to commute further.
The break-even calculation
At 12:1 commutation with CPI-linked DB indexation (~2.5% pa) and a real return of 3% on the invested lump sum, break-even is around 15–18 years of retirement. Cohort life expectancy at 67 is 85 (men) / 87 (women) — i.e. 18–20+ years of retirement for most healthy people. The pension wins in most cases.
| Scenario | Which wins & why |
|---|---|
| Healthy, normal life expectancy | Pension almost always wins → 20+ years of CPI-linked income beats a 12:1 lump invested at 3% real |
| Serious health condition | Lump sum may win → If your life expectancy is below the break-even (roughly 15 years) |
| Mortgage or debt to clear | Partial commutation → Clear high-interest debt with part, keep the indexed income on the rest |
| Low commutation factor (e.g. 10:1) | Keep the pension → Poor value — break-even pushes out past most life expectancies |
Commutation is irreversible. Once taken, you cannot reverse it. Transfers out of an unfunded public sector DB scheme (NHS, Teachers’, Civil Service) are generally not permitted; transfers from LGPS and private DB schemes above £30,000 require FCA-regulated advice by law.
Income tax and the Lump Sum Allowance on UK DB pensions
Pension income is taxed as earned income
Your DB pension is paid through PAYE by the scheme administrator. It counts as earned income for income tax but is exempt from National Insurance. Bands for 2026-27 (rUK — Scotland differs):
| Band | Income range | Rate |
|---|---|---|
| Personal Allowance | £0 – £12,570 | 0% |
| Basic rate | £12,571 – £50,270 | 20% |
| Higher rate | £50,271 – £125,140 | 40% |
| Additional rate | Above £125,140 | 45% |
A 30-year NHS 2015 member on a £52k salary retires on a £28,889 pension. Combined with the full new State Pension (£11,502), total taxable income is £40,391. After the Personal Allowance, £27,821 is taxed at 20% = £5,564 tax — leaving about £34,800 net.
The Lump Sum Allowance (LSA)
From 6 April 2024, the Lifetime Allowance was abolished and replaced by the Lump Sum Allowance: £268,275 of tax-free cash across all your pensions. You get up to 25% of each pension’s capital value tax-free, up to this overall cap. Anything over the LSA is taxed as income.
Protected lump sum amounts
If you hold Fixed Protection, Individual Protection, or Enhanced Protection from the pre-2024 LTA regime, your personal LSA may be higher — check with HMRC or an IFA. Protected cash from before A-Day (April 2006) can also give a higher tax-free lump sum.
Transfer and annual-allowance considerations
Taking a DB pension does not trigger the Money Purchase Annual Allowance (MPAA), unlike accessing DC pots flexibly. You keep the full £60,000 annual allowance. Transferring a DB scheme above £30,000 requires regulated advice (FCA-authorised adviser with pension transfer permissions).

| Civil Service Alpha | 2.32% per year | State Pension Age | CPI | No (commute) |
| Armed Forces 2015 | 1/47.875 | State Pension Age | CPI | No |
CARE vs Final Salary
Career Average Revalued Earnings (CARE) schemes use each year's salary, revalued forward each year. Final Salary schemes use your salary at retirement (or just before). Public sector schemes moved from Final Salary to CARE between 2014-2016 — protecting accrued rights but applying CARE to future service.
How the McCloud remedy affects UK public sector DB members
The 2015 reforms ruled discriminatory
When most public sector schemes moved to CARE in 2015, older members were "protected" and stayed in the legacy schemes. The Court of Appeal in 2018 ruled this was age discrimination (the McCloud case). The remedy applies to all members who were active in a public sector scheme between 1 April 2015 and 31 March 2022.
The "deferred choice" period
Eligible members can choose between the legacy scheme and CARE for the period 2015-2022 (the "remedy period"). The choice is made at retirement, not now, so members get to see actual pensions before deciding.
Who benefits most
Members whose salary grew quickly post-2015 are usually better off with the legacy Final Salary calculation. Members with steady or modest salary growth are usually better off with CARE. Public sector pension administrators provide modeller tools to help you decide.
Tax implications
The McCloud remedy may retrospectively change tax positions for the remedy period — including annual allowance excess charges. Members can request adjustments via the Public Service Pensions Remediable Service (PSRS) process.
Application to private sector
The McCloud remedy applies only to public sector schemes. Private sector DB members are not affected.
UK DB pension worked examples at retirement
NHS Band 7 nurse (30 years service)
Final salary £43,000, all service in NHS 2015 CARE: Annual pension ≈ £21,900/year. With 25% commutation: ≈ £16,400/year + £109,500 lump sum. Survivor's pension: 37.5% = £8,200/year.
Teacher (35 years, mix of pre/post 2015)
15 years on old Final Salary 1/80 + 20 years on Teachers' 2015 1/57 CARE: Final salary £55,000. Annual pension ≈ £10,300 (legacy) + £19,300 (CARE) = ≈ £29,600/year, plus automatic 3× = £30,900 lump sum from legacy scheme.
Senior university academic — USS
20 years on USS Final Salary + 15 years on USS CARE: £65,000 final salary, full career service. Approximate annual pension £24,500 + auto 3× lump sum £73,500. USS DC tier may add a separate pot of ~£200,000+ for above-threshold income.
Local government officer — LGPS
25 years' service, final salary £41,000, all on LGPS 2014 CARE: Annual pension ≈ £20,900/year (best of all the major schemes due to 1/49 accrual). No automatic lump sum — option to commute up to 25% at 12:1.
Early retirement reductions on UK defined benefit pensions
Standard reduction
If you retire before your scheme's Normal Pension Age (NPA), your annual pension is reduced by an "early retirement factor" — typically 4-5% per year early. Reductions are larger the further from NPA. A 10-year early retirement can reduce annual pension by 40-50%.
Examples by scheme
| Scheme | Years early | Pension reduction | Lump sum (auto) |
|---|---|---|---|
| NHS 2015 (NPA = SPA, 67) | 10 years (at 57) | ~46% | n/a |
| NHS 1995 (NPA = 60) | 5 years (at 55) | ~24% | Reduced by same % |
| LGPS (NPA = SPA) | 10 years | ~45% | n/a |
| USS (NPA = 66) | 10 years | ~50% | Auto 3× reduced by same % |
Protected pension ages
Some schemes preserve older NPAs for members with sufficient pre-reform service. NHS members with 1995-section service can usually access from age 60 without reduction. Teachers' pre-2007 members can usually access from age 60 unreduced.
Ill-health retirement
If you can't continue working due to ill-health, most public sector schemes pay an unreduced pension from any age, often with enhanced years of service added. Approval requires occupational health assessment.
Phased / partial retirement
NHS, LGPS, and USS now allow partial retirement — drawing some pension while continuing to work and accrue further benefits. Useful for transitioning to retirement gradually.
Common UK DB pension mistakes
Transferring out of a DB scheme
The FCA presumes that transferring a DB pension to a DC scheme is NOT in your best interests. Despite this, between 2015-2022 many members transferred and lost guaranteed lifetime income for cash they spent quickly. Only consider a transfer with FCA-regulated advice from a pension transfer specialist (PTS), and only if your circumstances are exceptional.
Underestimating the value of DB
A £25,000/year DB pension is the equivalent of approximately £500,000-£700,000 in a DC pot — much more than most people realise. Treat your DB scheme as a major retirement asset, not just a "small employer pension."
Not commuting when it makes sense
If you have substantial mortgage debt or need cash at retirement (one-off home modification, debt payoff), commuting 25% can be valuable. The breakeven is typically 15-18 years of retirement, so commutation is more attractive in poorer health or with high-interest debt to clear.
Forgetting to check Annual Benefit Statement
Each year you receive an Annual Benefit Statement from your scheme. Check accrual is correctly recorded, pensionable salary is accurate, and there are no missing years of service. Errors discovered years later can take significant effort to correct.
Ignoring Pension Tracing
If you've worked for multiple employers, you may have small DB entitlements from previous schemes. Use the government's Pension Tracing Service (free) to identify them — many small DB pensions go unclaimed.
❓ Frequently asked Frequently asked questions
How is a UK defined benefit pension calculated?
Annual pension = Pensionable salary × Years of service × Accrual rate. NHS 2015: 1/54 (1.85%). LGPS 2014: 1/49 (2.04%). Teachers’ 2015: 1/57. USS post-2016: 1/75 plus an automatic 3× lump sum. Civil Service Alpha: 2.32% of pensionable earnings per year. Check your Annual Benefit Statement for the authoritative figure.
How much tax-free lump sum can I take?
Up to 25% of the capital value of your pension, capped at £268,275 across all pensions (2026-27 Lump Sum Allowance). In schemes with an automatic lump sum — NHS 1995 (3/80), pre-2007 Teachers’ (3×), USS (3×) — the automatic cash already uses part of that 25%. Any additional commutation must fit within the remaining room.
What happens to my DB pension if I leave employment before retirement?
You become a “deferred member” — your accrued benefits are preserved and typically revalued by CPI until Normal Pension Age. You can usually take the pension from age 55 (57 from April 2028) with an early-retirement actuarial reduction, normally about 4–5% per year early.
Should I commute DB pension to a lump sum?
At the common 12:1 commutation rate, break-even is around 15–18 years of retirement. Most healthy UK retirees have a life expectancy well beyond that, so keeping the pension usually produces more total income. Commutation is more attractive if your scheme’s factor is generous, you have debt to clear, or your health is poor. It is irreversible — get FCA-regulated advice before deciding.
Is a UK DB pension protected if my employer fails?
NHS, Teachers’, LGPS, Civil Service, Armed Forces, Police and Firefighters’ schemes are underwritten by government and effectively guaranteed. Private sector DB schemes are covered by the Pension Protection Fund (PPF) — typically paying 90% of accrued benefits (capped for higher earners) with reduced indexation if the sponsor becomes insolvent.
What is the survivor pension on a UK DB scheme?
Most public sector DB schemes pay a spouse/civil partner pension of 37.5% of your pension for life. Children’s pensions are usually payable while children are under 23 and in education. Some schemes pay higher survivor rates or include dependant “nominations” — check your scheme rules.
Can I transfer a DB pension to a SIPP?
Only from a funded DB scheme (private sector, LGPS, USS). Unfunded public sector schemes (NHS, Teachers’, Civil Service, Armed Forces) are closed to transfers out. Any DB transfer over £30,000 requires FCA-regulated advice from an adviser with pension-transfer permissions (PTS). The FCA presumption is that transferring out of DB is not in your best interests — be sceptical of anyone who tells you otherwise.
