This calculator estimates the pension you could build as a prison officer in the Civil Service Pension Scheme, in its career-average section known as alpha. You pick your pay (the pay picker uses the 2026 Prison Service Pay Review Body scales) or type in your own pensionable pay, say how many years you have in the scheme and how many more you expect to work, and it shows the yearly pension, the contribution you pay, how the pension changes with the age you retire, and what happens if you swap some pension for a tax-free lump sum.
It runs in your browser and updates as you type. Nothing you enter is sent anywhere unless you choose to ask the AI question on the Ask AI tab, and then only the numbers on screen are used. Figures are as at 3 October 2026 and are estimates. Your real entitlement is held by the scheme administrator, and your annual benefit statement and any retirement quote are what count.
The free tabs are Your result, Year by year, Retirement ages, Real terms, Scenarios (A/B), Lump sum, Contributions and Divorce and sharing. The tabs after those (State Pension income to 90, the annual allowance check, a McCloud remedy estimate, a four-scenario lab and a printable briefing) are paid tools, and show a locked preview with a headline from your own numbers until you unlock them. The quick start at the top fills the whole calculator from four answers. The free tabs are not time-limited and do not need an account.
Alpha is a career-average scheme. Each scheme year (1 April to 31 March) you earn a pension of 2.32% of your pensionable earnings for that year. That block of pension is then revalued each following 1 April in line with CPI inflation while you stay in service. When you retire, the blocks are added together. The pension is not based on your final salary, so a pay rise late in your career lifts only the years after it.
A worked example. On £40,000 of pensionable pay, the pension earned in the year is £40,000 x 2.32% = £928. If you earned exactly £40,000 for 30 years and ignored revaluation altogether, the pension would be 30 x £928 = £27,840 a year. Real figures will differ, usually upwards, because each year's block is revalued by CPI (3.8% in April 2026, the figure confirmed from the September 2025 CPI used for public service pensions increase; the Great Britain revaluation order itself was not opened, so treat it as the working figure) and because your pay is likely to rise.
Alpha has no automatic lump sum. That is a difference from the older classic section, which paid three times the pension as a lump sum on retirement. In alpha you can choose to give up some pension for a tax-free lump sum, covered below. You need two years of qualifying service to be entitled to a pension at all.
Basic pay is pensionable. Whether particular allowances, Payment Plus or market supplements are pensionable is decided by the scheme manager under the scheme rules, and we have not been able to confirm it from a primary source, so we do not state it as fact. The calculator therefore asks you to enter the pensionable pay you want to model, and the pay picker is a starting point only.
The practical check is your payslip and your annual benefit statement. If an element of your pay does not attract a pension deduction, it is very likely not pensionable. If you are unsure, ask your establishment's HR or the pension administrator before relying on any estimate that includes it.
Your member contribution depends on your pensionable earnings for the year. The 2026/27 rates are set out below. The band rate applies to all of your pensionable earnings, not just the slice above a threshold, so crossing a boundary changes the rate on every pound. That is why £36,199 at 4.6% costs £1,665 a year but £36,200 at 5.45% costs £1,973.
| Annual pensionable earnings | Member rate |
|---|---|
| Up to £36,199 | 4.60% |
| £36,200 to £56,000 | 5.45% |
| £56,001 to £150,000 | 7.35% |
| Above £150,000 | 8.05% |
Source: Civil Service Pension Scheme contribution rates page and EPN743. The thresholds move each year with inflation.
On £40,000 of pensionable pay you are in the 5.45% band, so you pay £2,180 a year in member contributions. In return you earn £928 of pension for that year. The employer rate is separate and is paid by the department, not you: 28.97% of pay until 1 April 2027, then 22.32% (22.1% plus a 0.22% administration levy) from 1 April 2027. The employer rate matters when you compare alpha with a private or partnership arrangement, because the employer money alpha buys is large.
Use the Contributions tab to see your own figure and the Scenarios tab to compare, for example, a promotion that moves you across a band boundary with staying put.
In alpha your normal pension age is the later of your State Pension age and 65. For anyone born on or after 6 March 1961 and before 6 April 1977 that is 67. For those born from 6 April 1978 onwards, State Pension age is currently legislated to be 68, and the years in between phase in. A third State Pension age review was launched in July 2025 and no conclusion had been published as at 3 October 2026, so the legislated dates could change.
Prison officers have no lower pension age in alpha. The Public Service Pensions Act 2013 sets age 60 only for firefighters, police and the armed forces. The Prison Officers' Association has campaigned that a retirement age of 68 is too late for a physically and mentally demanding operational job, and the issue has been raised in Parliament, but we found no decision to change the age as at 3 October 2026. If that changes, this page and the calculator will be updated. Until then, the calculator uses the rules as they stand.
Older schemes are different. If you have service in classic, premium or classic plus, the normal pension age for that service is 60 and in nuvos it is 65. Prison officers in post on 30 September 1987 (31 October 1987 in Scotland) have special pre-Fresh Start rules in the 1972 classic section, but few serving officers remain in that group.
You can usually start an alpha pension from the minimum pension age, which is 55 now and rises to 57 from 6 April 2028. Taking it before your normal pension age means it is reduced, and the reduction is permanent. The size of the reduction depends on how many years and months early you are and on your own normal pension age.
The calculator uses the 2019 actuarial (GAD) reduction table, published by the Northern Ireland Department of Finance because the Great Britain version could not be opened. The Civil Service Pension Scheme says new factors apply to retirements from 1 November 2026, so these are illustrative estimates and are labelled as such. For example, on that table a £10,000 pension taken at 60 with a normal pension age of 67 pays 68.4% (£6,840), and with a normal pension age of 68 it pays 64.4% (£6,440). Retiring at 55 with a normal pension age of 65 pays 61.0% (£6,100).
If you already have a quote from the administrator, type the reduction from your quote into the Retirement ages tab. It overrides the table and your own figure is always the better one to use. Reductions apply to your own pension only, not to a survivor's pension, and the reduction is applied before any lump sum is taken.
You can give up some yearly pension for a tax-free lump sum at retirement. The scheme pays £12 of lump sum for each £1 a year of pension you give up. Give up £1,000 a year and you receive £12,000. The pension you keep falls by £1,000 for the rest of your life. On a flat pension the break-even is 12 years; if your pension rises by 2% a year with inflation the break-even is about 10.9 years, because the pension you gave up would have grown.
HMRC limits how much of the benefit can be taken as tax-free cash. The 25% test caps the fraction of the pension you can give up at 20 divided by (3 x 12 + 20), which is 35.7%. On a £10,000 pension that means a maximum lump sum of £42,857 and a remaining pension of £6,429. Separately, the lump sum allowance for 2026/27 is £268,275, which only starts to bind for pensions above roughly £62,600. The lifetime allowance was abolished from 6 April 2024.
Whether to take a lump sum is personal. It depends on debts, other income, health and how you feel about a guaranteed inflation-linked income versus cash now. The Lump sum tab shows both sides with your own numbers, and the separate pension lump sum calculator goes deeper. See also the lump sum guide.
Civil Service staff can generally choose between the defined-benefit alpha scheme and the partnership pension account, a money-purchase (defined contribution) arrangement where the money is invested with a provider. The Scottish Prison Service's own careers page mentions a partnership option with Legal & General as provider. Alpha is the default scheme.
The partnership account has an employer basic contribution, plus the employer matches your own contributions up to a further 3% of pay. We have not been able to verify the employer percentage by age band for Great Britain, so we do not quote one and the calculator does not model partnership as a like-for-like comparison. If you are weighing it up, ask your pension administrator for the current employer rates for your age.
The main differences are structural. Alpha promises a pension from a formula, revalued with inflation and paid for life, with a survivor's pension of 37.5%, death in service benefits and ill-health retirement terms built in. Partnership builds a pot whose size depends on contributions and investment returns, which you then turn into income yourself. The member contribution in alpha is a banded percentage and the large employer contribution (28.97%) buys a guaranteed benefit. Partnership trades that guarantee for flexibility and a pot you can pass on. For most prison officers who intend to stay in service the alpha formula is valuable, but your own plans, health and other pensions matter, and this is information rather than advice. A regulated financial adviser can help you decide.
Older members were protected when the 2015 reforms moved people into alpha, but the protection was found to be unlawfully age discriminatory (the McCloud case). The remedy covers service from 1 April 2015 to 31 March 2022. For that period you will be able to choose between legacy benefits (classic, premium, classic plus or nuvos) and alpha benefits. Service from 1 April 2022 is alpha for everyone.
For most active and deferred members the choice is deferred: you get a remediable service statement when you tell the scheme you plan to claim, and you choose then. The rules are in the Public Service (Civil Servants and Others) Pensions (Remediable Service) Regulations 2023 (SI 2023/942). Members who opted out between 12 March 2012 and 28 February 2022 may be able to buy back remedy-period service (see EPN738).
The calculator's McCloud tab is an opt-in, assumption-driven estimate. It is meant to show whether the choice is likely to matter for you, not to predict the answer. The remediable service statement from the administrator overrides it. Read the McCloud remedy guide before making a choice, and be aware we could not verify how the legacy pension age of 60 interacts with the remedy choice for prison officers in detail.
Your alpha pension is separate from the State Pension. The full new State Pension is £241.30 a week as published on GOV.UK, but your own amount depends on your National Insurance record, so check your forecast on GOV.UK. The paid Income to 90 tab layers the State Pension on top of your alpha pension so you can see the income picture across retirement.
The annual allowance for 2026/27 is £60,000. For a career-average scheme like alpha, the pension input amount for the year is 16 times the pension you earned in that year, so £40,000 of pay produces an input of 16 x £928 = £14,848. On this simple basis the allowance is only reached at pensionable pay above about £161,638. Tapering for very high earners and carry forward of unused allowance from the previous three years add complexity, and the paid Tax and allowance tab handles the main checks. Most prison officers will never reach it, but a large added-pension purchase can change that, so see the annual allowance guide if you are buying extra.
The Civil Service Pension Scheme has been administered by Capita since 1 December 2025. Before that it was MyCSP. Your annual benefit statement and the retirement quote you request from the administrator are the numbers that count. A pension statement guide explains how to read yours, and the Civil Service pension overview explains the schemes in more detail.
Pensions in payment rise each year. Public service pensions increase was 3.8% from 6 April 2026. Future increases depend on inflation, which nobody knows, so treat any projection that includes them as an assumption. See pension increases.

In alpha you earn 2.32% of pensionable pay each year, revalued by CPI. On £40,000 that is £928 for the year, and 30 years of flat £40,000 would be £27,840 a year before revaluation. Real pensions depend on your pay history, service, revaluation and the age you retire. Use the calculator for your own estimate.
In alpha it is the later of your State Pension age and 65, so 67 for most people born in the late 1960s and 1970s and 68 for those born from 6 April 1978. Prison officers have no lower age in alpha. The POA campaigns that 68 is too late, and no decision to change it had been found as at 3 October 2026.
You can usually start an alpha pension from 55, rising to 57 from 6 April 2028, but it is reduced for taking it early and the reduction is permanent. On the illustrative 2019 table, retiring at 55 with a normal pension age of 65 pays about 61% of the unreduced pension. Ask the administrator for a quote because new factors apply from 1 November 2026.
In 2026/27 the alpha member rates are 4.6% up to £36,199, 5.45% from £36,200 to £56,000, 7.35% from £56,001 to £150,000 and 8.05% above. The band rate applies to all pensionable earnings, so £40,000 pays 5.45%, which is £2,180 a year.
Not automatically in alpha. You can choose to swap pension for a tax-free lump sum at £12 for each £1 a year given up, subject to HMRC limits. Older classic service paid an automatic lump sum of three times the pension.
England and Wales (HMPPS) and Scotland (SPS) are both in the Civil Service Pension Scheme. Northern Ireland has the separate NICS scheme with different contribution bands, so do not apply the Great Britain figures to a Northern Ireland pension.
If you were in service between 1 April 2015 and 31 March 2022 you will be able to choose between legacy and alpha benefits for that period, usually when you retire. The calculator offers an opt-in estimate, but your remediable service statement overrides it. See the McCloud remedy guide.
Alpha gives a formula-based, inflation-linked pension for life with a large employer contribution. Partnership is a money-purchase pot with an employer contribution plus matching up to a further 3%. We could not verify the employer percentage by age for Great Britain. Which is better depends on your circumstances, so consider independent advice.
Capita has administered it since 1 December 2025, taking over from MyCSP. Your administrator holds your real figures and issues your annual statement and retirement quotes.
It applies published rules to the figures you enter, but it is an estimate. It does not know your pay history, which allowances are pensionable, exact revaluation or the new early-payment factors from 1 November 2026. Your administrator's statement is the authority.
Yes. The free tabs need no account. Pension Command (£39, one payment) adds State Pension income to 90, the annual allowance check, a McCloud estimate and a scenario lab, and the Pension & Lump-Sum Report (£14.99) gives a printable briefing.
